Detailed Description
In order to make the technical solutions better understood by those skilled in the art, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Fig. 1 is a system architecture diagram illustrating a control method of a server cluster applied to an embodiment of the present application. As shown in fig. 1, an execution subject of the embodiment of the present application may be, for example, a terminal, which may be an electronic device having a display screen, and the terminal includes but is not limited to: wearable devices, handheld devices, personal computers, tablet computers, in-vehicle devices, smart phones, computing devices or other processing devices connected to a wireless modem, and the like. The terminal devices in different networks may be called different names, for example: user equipment, access terminal, subscriber unit, subscriber station, mobile station, remote terminal, mobile device, user terminal, wireless communication device, user agent or user equipment, cellular telephone, cordless telephone, Personal Digital Assistant (PDA), terminal equipment in a 5th generation mobile network or future evolution network, and the like. The terminal system is an operating system that can run on the terminal, is a program for managing and controlling terminal hardware and terminal applications, and is an indispensable system application of the terminal. The system comprises but is not limited to Android system, IOS system, Windows Phone (WP) system, Ubuntu mobile version operating system and the like.
According to some embodiments, the terminal may be connected to the server through a network. The network is used to provide a communication link between the terminal and the server. The network may include various connection types, such as wired, wireless communication links, or fiber optic cables, to name a few. It should be understood that the number of terminals, networks, and servers in fig. 1 are merely illustrative. There may be any number of terminals, networks and servers, as desired for the reality. For example, the server may be a server cluster composed of a plurality of servers. The user may use the terminal to interact with the server over the network to obtain the desired message, etc.
It is easy to understand that when the server is in a working state, the terminal can monitor the state of the server cluster in real time, so that information that the server cluster has problems can be obtained in time. However, the terminal may adjust the server cluster only when the server cluster has a problem, which may increase the time length of the server cluster in the downtime state, so that the stability of the server cluster operation is poor. In addition, when a server cluster has a problem, a user needs to manually reallocate resources, control steps of the server cluster are increased, and control time of the server cluster is prolonged, so that the server cluster is inconvenient to use. Finally, when the number of servers is large, the monitoring cost of the server cluster can be increased by monitoring the state of the server in real time by the terminal.
The following describes in detail a control method for a server cluster according to an embodiment of the present application with reference to fig. 2 to 9. The execution bodies of the embodiments shown in fig. 2-9 may be terminals, for example.
Referring to fig. 2, a schematic flow chart of a control method of a server cluster is provided in the embodiment of the present application. As shown in fig. 2, the method of the embodiment of the present application may include the following steps S101 to S103.
Step S101, acquiring state parameters of a server cluster, wherein the server cluster comprises at least one server;
according to some embodiments, the execution subject of the embodiments of the present application may be a terminal, and may also be a system. The main implementation body of the present embodiment is described by taking a terminal as an example.
It is readily understood that a server cluster is a collection of servers that includes at least one server. The server cluster does not refer specifically to a fixed server cluster. For example, since the number of servers included in the server cluster is not fixed, when the number of servers changes, the server cluster also changes accordingly. For example, when the number of servers included in the server cluster is increased to 5, the server cluster may include a server cluster including 5 servers.
Optionally, when names of servers included in the server cluster change, the server cluster also changes accordingly.
According to some embodiments, the status parameters include, but are not limited to, Central Processing Unit (CPU) usage, disk input output IO, network input output IO, memory usage, disk usage, and the like. The status parameter may be one or more of the status parameters described above. The kind of the state parameter acquired by the terminal may be set based on a user setting instruction for the kind of the state. The category setting instructions include, but are not limited to, voice setting instructions, click setting instructions, text setting instructions, and the like.
Optionally, the category setting instruction received by the terminal may be, for example, a click setting instruction. When the terminal receives a click setting instruction input by a user, the terminal can set the state parameter corresponding to the click instruction to be in an acquirable state. At this time, an example schematic diagram of the terminal interface may be as shown in fig. 3.
It is easy to understand that the terminal can obtain the status parameters of the server cluster. For example, the terminal may obtain the state parameter of the server cluster when detecting that the current time is the state parameter obtaining time. The state parameter acquiring time can be set by the terminal based on a time setting instruction of a user, and can also be set by the terminal when the terminal leaves a factory. The time setting instruction includes but is not limited to a voice time setting instruction, a click time setting instruction, a timing time setting instruction, a text time setting instruction, and the like.
Alternatively, the time setting instruction received by the terminal may be, for example, a voice time setting instruction, and the voice time setting instruction may be, for example, "setting a time at which the number of minutes per hour includes the number 3 as the state parameter acquisition time". When the terminal receives the instruction, the terminal may set the time at which the number of minutes per hour includes the number 3 as the state parameter acquisition time. Therefore, when the current time is 0:03, the terminal can acquire the state parameters of the server cluster.
Step S102, when the state parameter is not matched with the preset state parameter, acquiring a first number of at least one server;
according to some embodiments, the preset state parameter may be set by the terminal before the state parameter of the server cluster is acquired, or may be set after the state parameter of the server cluster is acquired. For example, when the terminal receives a parameter setting instruction input by a user, the terminal may set the preset state parameter based on the parameter setting instruction. The parameter setting instructions include, but are not limited to, voice parameter setting instructions, click parameter setting instructions, text parameter setting instructions, and the like.
It is easy to understand that when the terminal obtains the state parameter of the server cluster, the terminal may detect whether the state parameter matches with the preset state parameter. When the terminal detects that the state parameter is not matched with the preset state parameter, the terminal can acquire the first number of the at least one server.
Optionally, the first number is a number of servers included in the server cluster, that is, a number of at least one server when the terminal acquires the state parameter of the server cluster. The first number does not refer to a fixed number. When the terminal modifies the number of servers included in the server cluster based on the number setting instruction input by the user, the first number may also be changed accordingly. For example, when the terminal acquires the state parameters of the server cluster for the first time, the first number acquired by the terminal may be, for example, 1. When the terminal acquires the state parameters of the server cluster again, the first number acquired by the terminal may be, for example, 5.
According to some embodiments, the state parameter of the server cluster acquired by the terminal may be, for example, a CPU usage rate, and the CPU usage rate may be, for example, 80%. The preset CPU usage may be 70%, for example. When the terminal acquires the CPU utilization rate, the terminal can detect whether the CPU utilization rate is matched with a preset CPU utilization rate. When the terminal detects that the CPU utilization rate is not matched with the preset CPU utilization rate of 70%, the terminal may acquire the number of servers included in the server cluster, that is, the terminal may acquire the first number of at least one server. The first number acquired by the terminal may be 1, for example.
Step S103, adjusting the first quantity based on the first quantity and the adjusting strategy.
According to some embodiments, when the terminal acquires the first number of the at least one server, the terminal may adjust the first number based on the first number and an adjustment policy. Wherein the adjustment of the first number by the terminal includes, but is not limited to, increasing the first number and decreasing the first number.
It is easy to understand that the adjusting strategy can be set by the terminal in advance based on the strategy setting instruction of the user, can also be determined by the terminal based on the state parameter and the preset state parameter, and can also be an adjusting algorithm trained by the terminal in advance. The policy setting instructions include, but are not limited to, voice policy setting instructions, click policy setting instructions, text policy setting instructions, and the like. For example, when the terminal receives a voice policy setting instruction input by a user, the terminal may set a corresponding adjustment policy. The voice policy setting instruction may be, for example, "1 server is added every time the CPU usage rate exceeds 10% of the preset CPU usage rate". Therefore, when the terminal detects that the CPU usage rate 80% exceeds the preset CPU usage rate 70%, the terminal may increase 1 server, i.e., adjust the first number of 1 to 2.
Alternatively, the adjustment strategy may be, for example, an adjustment algorithm, wherein different state parameters may correspond to different adjustment algorithms. When the terminal acquires that the CPU utilization may be 80%, for example, and the terminal determines that the number of servers included in the server cluster is 2 by using an adjustment algorithm of the CPU utilization, at this time, the terminal may increase 1 server, that is, adjust the first number of servers to 1 to 2.
In one or more embodiments of the present application, the terminal may adjust the first number based on the first number of the at least one server and the adjustment policy when the state parameter is not matched with the preset state parameter by obtaining the state parameter of the server cluster. By adopting the adjustment strategy to adjust the first quantity, the server cluster does not need to be adjusted when the server cluster is in the downtime state, the probability that the server cluster is in the downtime state can be reduced, the time length that the server cluster is in the downtime state is reduced, and the running stability of the server cluster can be improved. In addition, the terminal does not need manual operation of a user for adjusting the first number, so that the waiting time of user operation is reduced, the operation steps of the server cluster can be reduced, and the convenience of server cluster control is improved.
Please refer to fig. 4, which is a flowchart illustrating a control method for a server cluster according to an embodiment of the present application. As shown in fig. 4, the method of the embodiment of the present application may include the following steps S201 to S203.
Step S201, acquiring state parameters of a server cluster;
step S202, when the state parameters are not acquired within a preset time, determining that the server cluster is in a downtime state;
according to some embodiments, the preset duration refers to a duration in which the terminal does not acquire the state parameter. The preset duration may be set by the terminal based on a preset duration setting instruction input by the user. The preset duration setting instruction includes, but is not limited to, a voice preset duration setting instruction, a click preset duration setting instruction, a timing preset duration setting instruction, and the like. The preset time length may be the same as or longer than the interval time length for the terminal to obtain the state parameter.
It is easy to understand that the preset time duration may be greater than the interval time duration for the terminal to obtain the state parameter of the server cluster. For example, the interval duration set by the terminal may be, for example, 5 seconds. The preset time period set by the terminal based on the preset time period setting instruction input by the user may be, for example, 10 seconds. When the terminal does not acquire the state parameters of the server cluster within 10 seconds of the preset time, the terminal can determine that the server cluster is in the downtime state. The downtime state refers to the state that the server cluster is in a crash state.
According to some embodiments, when the servers include a plurality of servers, the terminal may determine that a server in a downtime state exists in the server cluster when the terminal detects that a parameter change of a state parameter of the server cluster within a certain time period exceeds a preset change parameter range. For example, when the server cluster includes 5 servers, and when the parameter variation between the current CPU utilization rate and the last CPU utilization rate acquired by the terminal exceeds 30%, the terminal may determine that there are servers in the downtime state in the plurality of servers.
Step S203, sending a first reminding message, where the first reminding message is a message that the server cluster is in a downtime state.
According to some embodiments, when the terminal does not acquire the state parameter of the server cluster within the preset time length and determines that the server cluster is in the downtime state, the terminal may send out the first reminding information. The first reminding information does not refer to a fixed reminding information. For example, when a server included in the server cluster changes, the first reminding information also changes correspondingly.
It will be readily appreciated that the server cluster may comprise, for example, a servers. When the terminal does not acquire the state parameters of the server A within 10 seconds, the terminal can determine that the server A is in a downtime state, and at the moment, the terminal can send out first reminding information. The first reminding information may be, for example, "please note: server a is in a down state. At this time, an exemplary diagram of the terminal interface may be as shown in fig. 5.
According to some embodiments, when the server cluster includes a plurality of servers, the terminal may detect whether the status parameters of the plurality of servers are received within a preset time period based on the server identifications of the servers. The plurality of servers may be, for example, B1 servers, B2 servers, B3 servers, B4 servers, and B5 servers. When the terminal detects that the state parameter of the B2 server is not received within the preset time period based on the server identifier, the terminal may determine that the B2 server is in a downtime state, and at this time, the terminal may send out the first reminding information. The first reminder may be, for example, that the B2 server is down.
In one or more embodiments of the application, the terminal may determine that the server cluster is in the downtime state by acquiring the state parameter of the server cluster when the state parameter is not acquired within a preset time period, and may send the first reminding information to remind a user of information that the server cluster is in the downtime state, so that the time period for the user to acquire the first reminding information may be reduced, the adjustment time period of the server cluster is reduced, and the operation stability of the server cluster is improved.
Please refer to fig. 6, which is a flowchart illustrating a control method for a server cluster according to an embodiment of the present application. As shown in fig. 6, the method of the embodiment of the present application may include the following steps S301 to S307.
Step S301, setting interval duration of parameter acquisition;
according to some embodiments, the interval duration is a time difference between the current parameter obtaining time point and a last parameter obtaining time point of the current parameter obtaining time point. The terminal may set the interval duration to a fixed duration, and the terminal may also set the interval duration to a non-fixed duration. For example, the terminal may set the interval duration to 5 seconds, and the terminal reaches the parameter acquisition time point every 5 seconds.
Optionally, the terminal may further set the interval duration to be a non-fixed duration. For example, the terminal may set an interval duration between the first time parameter acquisition time point and the second time parameter acquisition time point to be 5 seconds, an interval duration between the second time parameter acquisition time point and the third time parameter acquisition time point to be 10 seconds, and the like.
According to some embodiments, the terminal may further set a parameter acquisition time point within a fixed period. For example, the terminal may use half-hour as a cycle, and every half-hour, the interval between the first 10-minute parameter acquisition is 3 seconds, the interval between the second 10-minute parameter acquisition is 5 seconds, and the interval between the third 10-minute parameter acquisition is 4 seconds.
Step S302, acquiring the state parameters of the server cluster at intervals;
according to some embodiments, when the terminal sets the interval duration for completing parameter acquisition, the terminal may acquire the state parameters of the server cluster once every interval duration. The terminal may control a sampling module in the terminal to collect the state parameters of the server cluster, for example. For example, the terminal may set the interval duration to a fixed duration of 5 seconds. Then after the terminal acquires the status parameters of the server cluster once in 00:05, the terminal may acquire the status parameters of the server cluster once in 00: 10.
Step S303, when the state parameter is not matched with the preset state parameter, acquiring a first number of at least one server;
step S304, acquiring target state parameters;
according to some embodiments, the target status parameter refers to a parameter after the terminal adjusts the status parameter when the status parameter does not match the preset status parameter. The target state parameter does not refer to a fixed parameter in particular, the target parameter may be determined based on a parameter setting instruction of a user, and the target state parameter may also be consistent with a preset state parameter.
It is easy to understand that when the terminal determines that the state parameter does not match the preset state parameter, the terminal may obtain the target state parameter. The step 303 and the step 304 may be interchanged or performed simultaneously, that is, the terminal may obtain the target state parameter while obtaining the first number of the at least one server, the terminal may further obtain the target state parameter after obtaining the first number of the at least one server, and the terminal may further obtain the first number of the at least one server after obtaining the target state parameter.
Optionally, for example, the state parameter of the server cluster acquired by the terminal may be a CPU utilization rate, and the CPU utilization rate may be 80%, for example. The preset CPU usage may be 70%, for example. When the terminal acquires the CPU utilization rate, the terminal can detect whether the CPU utilization rate is matched with a preset CPU utilization rate. When the terminal detects that the CPU utilization rate is not matched with the preset CPU utilization rate of 70%, the terminal may acquire the number of servers included in the server cluster, that is, the terminal may acquire the first number of at least one server. The first number acquired by the terminal may be 1, for example. In this case, the target state parameter acquired by the terminal may be, for example, a CPU target usage rate of 40%.
Step S305, determining an adjusting strategy based on the target state parameter and the state parameter;
according to some embodiments, when the terminal acquires the target state parameter, the terminal may determine an adjustment policy based on the target state parameter and the state parameter. For example, the terminal may determine the adjustment strategy based on the target state parameter and a ratio, difference, etc. between the state parameters.
It is easily understood that, for example, the target state parameter acquired by the terminal may be, for example, the CPU target usage rate of 40%. The state parameter acquired by the terminal may be, for example, a CPU usage rate of 80%. When the terminal acquires the target utilization rate of the CPU and the CPU utilization rate, the adjustment policy determined by the terminal may be, for example, that the number of servers included in the server cluster is 2.
Step S306, acquiring a second quantity adjusted by at least one server corresponding to the adjustment strategy, and adjusting the first quantity to the second quantity;
according to some embodiments, the second number refers to a number adjusted with the at least one server, the second number corresponding to the adjustment policy. The second number does not refer to a fixed number. For example, if the target state variable or state variable changes, the control strategy will also change, as will the second quantity.
It is easy to understand that, when the terminal determines the adjustment policy based on the target state parameter and the state parameter, the terminal may obtain the adjusted second number of the at least one server corresponding to the adjustment policy. When the terminal acquires the second number, the terminal may adjust the first number to the second number.
According to some embodiments, for example, the target state parameter acquired by the terminal may be, for example, that the CPU target usage rate is 40%. The state parameter acquired by the terminal may be, for example, a CPU usage rate of 80%. When the terminal acquires the target utilization rate of the CPU and the CPU utilization rate, the adjustment policy determined by the terminal may be, for example, that the number of servers included in the server cluster is 2. When the terminal determines that the first number is 1, the terminal may adjust the first number 1 to the second number 2.
According to some embodiments, for example, the target state parameter acquired by the terminal may be, for example, that the CPU target usage rate is 40%. The state parameter acquired by the terminal may be, for example, a CPU usage rate of 20%. When the terminal acquires the target utilization rate of the CPU and the CPU utilization rate, the adjustment policy determined by the terminal may be, for example, that the number of servers included in the server cluster is 2. When the terminal determines that the first number is 4, the terminal may adjust the first number of 4 to the second number of 2. That is, when the terminal determines that the CPU utilization is lower than the minimum value of the preset CPU utilization, the terminal may reduce the number of servers to improve the utilization of the servers.
Referring to fig. 7, a flow chart of a sharing screen switching method according to some embodiments is provided. As shown in fig. 7, the method of the embodiment of the present application may include the following steps S401 to S405 when adjusting the first number to the second number. Step S401, when the second quantity is larger than the first quantity, obtaining a third quantity of servers, wherein the third quantity of servers are in an idle state; s402, calculating a fourth quantity, wherein the fourth quantity is the difference quantity between the second quantity and the first quantity; s403, when the third number is larger than or equal to the fourth number, adjusting the first number to the second number; s404, when the third number is smaller than the fourth number, acquiring a fifth number of servers from the cloud server, wherein the fifth number is a difference number between the third number and the fourth number, and the fifth number of servers are in an idle state; s405, when the fifth number of servers are acquired, the first number is adjusted to the second number.
According to some embodiments, when the terminal acquires the second number, the terminal may acquire a third number of servers in an idle state in the server system. For example, when the user acquires that the terminal is in the idle state, the user inputs that the terminal is in the idle state, that is, the terminal may record that the terminal is in the idle state. When the server in the idle state is used, that is, the server is not in the idle state, the terminal may record the server, so that the terminal may acquire the server in the idle state.
It is easy to understand that, when the terminal acquires the second number, the terminal may calculate a fourth number, which is a difference number between the second number and the first number. When the terminal acquires the third number and the fourth number, the terminal may detect a size relationship between the third number and the fourth number. When the terminal detects that the third number is greater than or equal to the fourth number, the terminal may adjust the first number to the second number.
Optionally, for example, when the second number acquired by the terminal is 2 and the first number is 1, the fourth number calculated by the terminal may be 1, for example. The third number acquired by the terminal may be, for example, 4, and when the terminal detects that the third number is 4 greater than the fourth number of 1, the terminal may adjust the first number of 1 to the second number of 2.
According to some embodiments, when the terminal acquires the third number and the fourth number, the terminal may detect a size relationship between the third number and the fourth number. When the terminal detects that the third number is smaller than the fourth number, the terminal may obtain a fifth number of servers from the cloud server, where the fifth number is a difference number between the third number and the fourth number. The fifth number of servers are in an idle state, that is, the terminal obtains the fifth number of servers in an idle state from the cloud server. When the terminal acquires the fifth number of servers, the terminal may adjust the first number to the second number.
Optionally, for example, when the second number acquired by the terminal is 5 and the first number is 1, the fourth number calculated by the terminal may be 4, for example. The third number acquired by the terminal may be, for example, 2, and when the terminal detects that the third number is 2 and is greater than the fourth number by 4, the terminal calculates that the fifth number is 2. The terminal acquires a fifth number of servers in an idle state from the cloud server, that is, the terminal can acquire 2 servers in the idle state. When the terminal acquires the fifth number of servers, the terminal may adjust the first number of 1 servers to the second number of 5 servers.
According to some embodiments, when the terminal acquires the third number and the fourth number, the terminal may detect a size relationship between the third number and the fourth number. When the terminal detects that the third number is smaller than the fourth number, the terminal may directly acquire the fourth number of servers from the cloud server, where the fourth number of servers are in an idle state, that is, the terminal acquires the fourth number of servers in an idle state from the cloud server. When the terminal acquires the fourth number of servers, the terminal may adjust the first number to the second number.
Optionally, for example, when the second number acquired by the terminal is 5 and the first number is 1, the fourth number calculated by the terminal may be 4, for example. The third number obtained by the terminal may be, for example, 2, and when the terminal detects that the third number is 2 and is greater than the fourth number, 4, the terminal may directly obtain the fourth number of servers in the idle state from the cloud server, that is, the terminal may obtain 4 servers in the idle state from the cloud server. When the terminal acquires the fourth number of servers, the terminal may adjust the first number of 1 servers to the second number of 5 servers.
Step S307, sending out second reminding information, wherein the second reminding information is information of adjusting the first quantity to the second quantity.
According to some embodiments, the terminal may send the second reminding message after the terminal adjusts the first number to the second number. The second reminder information may be information that the first number is adjusted to the second number so that the user can know explicitly that the number of servers included in the server cluster has changed. The terminal can be provided with a notification module, and when the terminal sends out the reminding information, the terminal can control the notification module to send out the reminding information.
It is easy to understand that, for example, when the second number acquired by the terminal is 2 and the first number is 1, the fourth number calculated by the terminal may be 1, for example. The third number acquired by the terminal may be, for example, 4, and when the terminal detects that the third number is 4 greater than the fourth number of 1, the terminal may adjust the first number of 1 to the second number of 2. The second reminder information generated by the terminal may be, for example, information for adjusting the first number of 1 to the second number of 2. The terminal may display the second reminder information on a display screen of the terminal, for example. At this time, an example schematic diagram of the terminal interface may be as shown in fig. 8.
In one or more embodiments of the present application, the terminal may set an interval duration for acquiring the parameter, and acquire the state parameter of the server cluster at intervals, and when the number of servers included in the server cluster is large, the terminal may also monitor the operating states of the servers, so as to reduce the monitoring cost of the server cluster. In addition, when the state parameters are not matched with the preset state parameters, the terminal can determine the adjusting strategy based on the target state parameters and the state parameters, and adjust the first quantity to the second quantity based on the adjusting strategy, so that the accuracy of obtaining the adjusting strategy can be improved, the accuracy of adjusting the first quantity is improved, the server cluster does not need to be adjusted when the server cluster is in the downtime state, the probability of the server cluster in the downtime state can be reduced, and the running stability of the server cluster can be improved. In addition, when the terminal adjusts the first number, manual operation of a user is not needed, operation steps of the server cluster can be reduced, and convenience of server cluster control is improved. Finally, the terminal can send out second reminding information so as to remind the user of the information that the first quantity is adjusted to the second quantity, the time length that the user obtains the second reminding information can be reduced, and the use experience of the user is improved.

step S502, when the state parameter is not matched with the preset state parameter, acquiring a first number of at least one server;
step S503, acquiring a historical adjustment strategy;
according to some embodiments, the terminal may adjust the first number of the at least one server based on a historical adjustment policy. When the terminal acquires the first number of the at least one server, the terminal may acquire a history adjustment policy. The terminal may, for example, control a policy module in the terminal to retrieve the historical adjustment policy from a data center in the terminal. The historical adjustment policy may include, for example, a historical adjustment time point, a historical adjustment quantity, and the like.
It is easy to understand that the historical adjustment strategy does not refer to a fixed adjustment strategy, and may be an adjustment strategy obtained based on a user strategy acquisition instruction. When the policy acquisition instruction of the user changes, the history adjustment policy acquired by the terminal also changes correspondingly.
According to some embodiments, the policy acquisition instruction received by the terminal before acquiring the historical adjustment policy may be, for example, acquiring the adjustment policy of the previous day. When the state parameter of the server cluster acquired by the terminal is 2019, 5 and 12 days, the historical adjustment policy acquired by the terminal may be, for example, an adjustment policy of 2019, 5 and 11 days.
Step S504, acquiring the target quantity of at least one server after adjustment corresponding to the historical adjustment strategy based on the historical adjustment strategy;
according to some embodiments, the target number refers to a number adjusted by at least one server corresponding to the historical adjustment policy, and does not refer to a fixed number. For example, when the history adjustment strategy is changed, the target number is changed correspondingly.
It is easy to understand that, when the terminal acquires the history adjustment policy, the terminal may acquire the target number adjusted by the at least one server corresponding to the history adjustment policy. The target number corresponding to the history adjustment strategy may be fixed or may be changed based on a time point. For example, the target number corresponding to the history adjustment policy may be 2. The target number corresponding to the history adjustment strategy can also be 1 for 2:00am, 2 for 10:00am and 5 for 8:00 pm.
Step S505, adjust the first number to the target number.
According to some embodiments, when the terminal acquires the target number corresponding to the history adjustment policy, the terminal may adjust the first number to the target number. For example, the historical adjustment policy may be an adjustment policy of 5/11/2019, and when the target number corresponding to the historical adjustment policy may be 2, the terminal may adjust the first number of 12/5/2019 to 2.
It is easy to understand that when the target number corresponding to the history adjustment policy can also be 1 for the target number of 2:00am, 2 for the target number of 10:00am, and 5 for the target number of 8:00pm, the terminal can adjust the first number to 1 for 2:00am, 2 for 10:00am, and 5 for 8:00pm in 5 months and 12 days in 2019.
In one or more embodiments of the present application, a terminal may obtain a state parameter of a server cluster, and when the state parameter is not matched with a preset state parameter, the terminal may obtain a historical adjustment policy, and adjust the first number to a target number based on the historical adjustment policy. The terminal adjusts the first quantity to the target quantity based on the historical adjustment strategy, so that the accuracy of first quantity adjustment can be improved, the server cluster does not need to be adjusted when the server cluster is in the downtime state, the probability that the server cluster is in the downtime state can be reduced, and the running stability of the server cluster can be improved.
