To make the object, technical solutions and advantages of the present invention clearer, below in conjunction with the accompanying drawings and specific embodiment to this
Invention is described in further detail.
As shown in figure 3, an embodiment of the present invention provides a kind of method for processing business, this method may comprise steps of：
Step 301：The configuration of activestandby state is carried out for server mu01 and server mu02.
In order to ensure the normal operation of business processing, especially in HPC cluster, two servers may be used to HPC
Cluster carries out job scheduling, and when ensureing one of server fail, another server can substitute the failure
Server works.
In the initial state, can be that server mu01 is configured to primary shape for server mu01 and server mu02
State is configured to stand-by state using as standby server using as primary server, for server mu02.
Step 302：The configuration of configuration file is carried out to primary server mu01.
In an embodiment of the invention, primary server mu01 can be configured as follows：The synchronous mesh of configuration
Record and synchronisation key.
Wherein, which may include multiple directory entries, be needed to the synchronous directory for characterizing primary server
In included each directory entry be monitored.
Wherein, to primary clothes when synchronisation key is for realizing that data synchronize between primary server and standby server
What the identity of business device was verified.Due to, when carrying out data interaction, if without authentication, being subject between server
To the attack of malice degree or rogue device, threaten to the data safety of server.
In an embodiment of the invention, a kind of following configuration file can be utilized to realize the configuration to primary server：
<Localpath watch="/opt/tsce/server_priv "><！- synchronous directory -->
<Remote ip=" mu02 " name=" scheduler "/><！- remote server -->
</localpath>
<rsync>
<CommonParams params="-artuz "/>
<Auth start=" true " users=" root " passwordfile="/etc/rsync.pas "/>
<UserDefinedPort start=" false " port=" 874 "/><！-- port=874-->
<Timeout start=" false " time=" 100 "/><！-- timeout=100-->
<Ssh start=" false "/>
</rsync>
In an embodiment of the invention, since the state for being related to two-server in the follow-up process switches,
It also needs to realize the configuration to server mu02 according to above-mentioned configuration file.
Step 303：The configuration of configuration file is carried out to standby server mu02.
In an embodiment of the invention, standby server mu02 can be configured as follows：The synchronous mesh of configuration
Record and synchronisation key.
Wherein, which may include multiple directory entries, need to realize and primary clothes for characterizing standby server
Business device synchronizes the data of each directory entry included in the synchronous directory.
Wherein, to primary clothes when synchronisation key is for realizing that data synchronize between primary server and standby server
What the identity of business device was verified.Due to, when carrying out data interaction, if without authentication, being subject between server
To the attack of malice degree or rogue device, threaten to the data safety of server.
In an embodiment of the invention, a kind of following foot configuration file realization can be utilized to match standby server
It sets：
In an embodiment of the invention, since the state for being related to two-server in the follow-up process switches,
It also needs to realize the configuration to server mu01 according to above-mentioned configuration file.
Step 304：Server mu01 is when monitoring that data change has occurred, update lock file.
In an embodiment of the invention, server mu01 needs each included by preconfigured synchronous directory
A directory entry is monitored data, when monitoring that data change has occurred, needs the attribute information for changing data update
Into lock file.
Wherein, which can include but is not limited to following information：Job property, operation ID number, belonging to the operation
Resource and operation submission time etc. used in user name, jobs node.
Step 305：The target directory item and corresponding changed data and synchronisation key that data change will have occurred
It is pushed to server mu02.
In an embodiment of the invention, in order to ensure that server mu02 can root after server mu01 breaks down
According to data normal operation in server mu01, need to carry out data synchronization between two servers.In order to reduce by two servers
Between data transmission data volume, server mu01 need to only give the data-pushing changed to server mu02.
Step 306：The synchronisation key that server mu02 sends server mu01 according to the synchronisation key itself configured into
Row verification, when being verified, continues to execute next step.
In an embodiment of the invention, if synchronisation key does not pass through, refusal and server mu01 progress data are same
Step update.
Step 307：Server mu02 carries out local synchronization update operation according to the changed data received.
In an embodiment of the invention, server mu02 can be according to each mesh in the information of server mu01 push
Mark directory entry determines the directory entry that data change has occurred, and changed data are updated into corresponding directory entry, to
Realize the synchronized update of local data.
Step 308：Server mu02 stores the lock file being currently received.
Step 309：By the lock file being currently received and all locks received in current target time section text
Part is compared, when comparison result includes the lock file being currently received and all lock file all sames, it is determined that service
Device mu01 breaks down.
Wherein, which can pre-set, for example, 10s.
Assuming that receiving lock file 1, lock file 2 and lock file 3, clothes altogether in the lock file 10s that distance is currently received
Business device mu02 needs to scan this four lock files one by one, and compare the lock file that is currently received whether with lock file 1,
File 2 and lock 3 all same of file are locked, if so, determining that failure has occurred in server mu01.
Step 310：Oneself state is switched to master state by server mu02, the work of take over server mu01, and to
Server mu02 sends the notice of state switching.
Step 311：Server mu01 is switched to stand-by state according to the notice, by oneself state.
Referring to FIG. 4, an embodiment of the present invention provides a kind of primary servers, including：
Monitoring unit 401 has occurred data change for monitoring whether, and is triggered monitoring to have occurred when data change
Updating unit executes corresponding operating；
The updating unit 402, for updating lock file；
