Detailed Description
To make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is apparent that the described embodiments are some, but not all embodiments of the present invention. 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 invention.
In a public cloud network architecture, differentiating between OVER L AY and UNDER L AY, the tenant's VPC (Virtual private cloud) network is in OVER L AY, while the hosted hadoop management service is deployed in UNDER L AY.
In view of the problem that the network security of a cloud host is reduced by a manner of accessing a tenant cloud host by a management server at present, embodiments of the present invention provide a data communication method, an apparatus, and an electronic device. For the convenience of understanding the present embodiment, a data communication method disclosed in the present embodiment will be described in detail first.
Referring to fig. 1, a flow chart of a data communication method according to an embodiment of the present invention is shown, where the method is applied to a management server running a data distributed processing management service. As can be seen from fig. 1, the method comprises the following steps:
step S102: if the target private cloud host needs to be accessed, establishing communication connection with a preset tunnel server; and a communication tunnel is pre-established between the tunnel server and the target private cloud host.
The cloud host is a part which is similar to a plurality of independent hosts and is virtualized on a group of cluster hosts, and each host in the cluster is provided with a mirror image of the cloud host, so that the safety and stability of the virtual host are greatly improved. The cloud host integrates IT infrastructure capacity renting services of computing, storage and network resources, and can provide server renting services of on-demand use and on-demand payment capacity based on a cloud computing mode. Here, the private cloud host is a cloud host private to the tenant, and the data resource of the cloud host has specificity and confidentiality, as compared with the common cloud host.
In this embodiment, the data communication method is applied to a management server running a data distributed processing management service, and when the management server needs to access a target private cloud host, a communication connection is first established with a preset tunnel server. Here, the tunnel server is a server for providing a tunnel communication service. And a communication tunnel is pre-established between the tunnel service and the target private cloud host.
In one possible embodiment, the management server may establish a communication connection with a preset tunnel server by:
establishing communication connection with a preset tunnel server through a preset proxy protocol; the tunnel server runs a proxy protocol service matched with the proxy protocol, and the proxy protocol service is used for establishing communication connection between the tunnel server and the management server.
Here, the proxy Protocol may be a sockets (Protocol for sessions transfer across firewall device security) Protocol, where the sockets Protocol provides a kind of forwarding of a TCP (Transmission Control Protocol) session on a firewall server, allowing a user to transparently penetrate through a firewall. The socks protocol is completely independent of the protocol of the application layer, and the examination of the access authority can be completed before the TCP session is started, and then only the back-and-forth forwarding is needed. Furthermore, since the socks protocol is not concerned with the protocol of the application layer, the application layer communication can be encrypted to protect the content of the own communication from being seen by the agent.
In this embodiment, a proxy protocol service is run on the tunnel server, and the proxy protocol service is matched with a preset proxy protocol, so that the tunnel server establishes a communication connection with the management server through the preset proxy protocol based on the proxy protocol service.
In one possible embodiment, to improve the stability of the tunnel communication service, more than one tunnel server may be provided, for example, assuming that there are a master tunnel server and a slave tunnel server, at which time the management server may establish a communication connection with the tunnel server through the following steps 21-22:
(21) determining a target tunnel server from preset tunnel servers through a preset load balancer; the preset tunnel server comprises a main tunnel server and a slave tunnel server, and the main tunnel server and the slave tunnel server operate proxy protocol service.
Here, the load balancer is used to achieve high availability of the master tunnel server and the slave tunnel servers. In actual operation, the load balancer distributes the requests to the main tunnel server and the slave tunnel servers randomly or in a polling mode, NGINX services run on each tunnel server, the NGINX services forward the request groups again, the main tunnel server transfers the requests to the load balancer, and the slave tunnel servers transfer the requests to the main tunnel server. The NGINX service of the slave tunnel server can automatically sense the health state of the master tunnel server, and if the slave tunnel server is unhealthy, all requests can be forwarded to the slave tunnel server, so that high availability is realized.
(22) And establishing communication connection with the proxy protocol service on the target tunnel server through a preset proxy protocol.
Step S104: and accessing the target private cloud host through the tunnel server and the communication tunnel.
After the management server establishes a communication connection with a preset tunnel server, the management server may send an access request to the tunnel server; because a communication tunnel is pre-established between the tunnel server and the target private cloud host, the tunnel server can forward the access request to the target private cloud host through the communication tunnel, so that the management server can access the target private cloud host.
In one possible implementation, the management server may implement the step of accessing the target private cloud host through the tunnel server and the communication tunnel by the following steps 31 to 33:
(31) sending an access request to the tunnel server; the access request carries an identifier of the target private cloud host; a target port matched with the target private cloud host is preset in the tunnel server; and a communication tunnel is pre-established between the target port and the target private cloud host.
(32) And determining a target port matched with the target private cloud host according to the identifier of the target private cloud host.
Here, since the communication tunnel is pre-established between the target port and the target private cloud host, the target port is associated with the target private cloud host, and the target port associated with the target private cloud host can be determined according to the identifier of the target private cloud host.
(33) And sending the access request to the target private cloud host through the target port and the communication tunnel.
Thus, through the steps S102 to S104, the management server directly accesses the target private cloud host, and compared with the existing manner of binding an intranet EIP for each host in the hosted cluster, the data communication method provided by this embodiment can avoid mutual access between private cloud hosts of different tenants, and improve the network security of the private cloud hosts.
Referring to fig. 2, an application scenario schematic diagram of a data communication method according to an embodiment of the present invention is shown, in the application scenario shown in fig. 2, two tunnel services are provided: a master tunnel server (master proxy) and a slave tunnel server (slave proxy), and the management server accesses the target private cloud host through the load balancer. In addition, a Nginx service is run on both the master tunnel server and the slave tunnel server, which is used to provide a reverse proxy service.
In the embodiment shown in fig. 2, when the management server needs to connect to the target private cloud host, the following commands are implemented:
ssh root@127.0.0.1-p22-i/home/kmr/.ssh/id_rsa_tunnel-o"ProxyCommand＝nc--proxy-type socks5--proxy 10.172.1.187:6668127.0.0.1${vm_port}"。
specifically, the management server first establishes a sockets 5 protocol connection through 6668 port on the load balancer, and then connects to the cloud host through a sockets 5 protocol. The load balancer randomly distributes the connection of 6668 ports to the main tunnel server and the slave tunnel server, if the connection is distributed to the main tunnel server node, the Nginx service on the main tunnel server forwards the connection to 10.200.0.19:6000 ports of the main tunnel server; if distributed to the slave tunnel server, the Nginx service on the slave tunnel server will forward the connection to the 10.200.0.19:6000 port of the master tunnel server. After the Socks5 protocol connection is established, the tunnel server is connected to the target private cloud host through the Socks5 protocol, and the target private cloud host has an address of: "127.0.0.1 $ { vm _ port }".
According to the data communication method provided by the embodiment of the invention, if the target private cloud host needs to be accessed, communication connection is established with the preset tunnel server; a communication tunnel is pre-established between the tunnel server and the target private cloud host; and accessing the target private cloud host through the tunnel server and the communication tunnel. In the method, the communication tunnel is established between the private cloud host and the tunnel server, when the management server needs to access the private cloud host, the management server can directly access the private cloud host through the tunnel server and the corresponding communication tunnel, and meanwhile, mutual access between the private cloud hosts of different tenants is avoided, so that the network security of the private cloud host is improved.
An embodiment of the present invention further provides another data communication method, and referring to fig. 3, a flowchart of the another data communication method is shown, where the method is applied to a private cloud host, and a communication tunnel is pre-established between the private cloud host and a preset tunnel server. As can be seen from fig. 3, the method comprises the following steps:
step S302: if receiving the access request from the management server, responding to the access request to obtain a response result; after the management server establishes communication connection with the tunnel server, the access request is sent through the tunnel server and the communication tunnel; the management server runs a data distributed processing management service.
In the foregoing embodiment, the process of establishing a communication connection between the management server and the tunnel server is described from the management server side, and after the management server establishes a communication connection with the tunnel server, the management server forwards the access request to the target private cloud host through the tunnel server. In this embodiment, from the private cloud host side, processing of the received access request by the private cloud host is described. Here, the private cloud host responds to the received access request and obtains a response result.
In addition, the communication tunnel may be established by: when the private cloud host monitors a startup signal, a communication tunnel creation request is sent to a preset tunnel server, so that a communication tunnel with the private cloud host is created through the tunnel server. In practice, an executable script may be introduced by introducing a UserParam parameter when creating the private cloud host, such as: a ssh-R command; the script is used for creating a tunnel service and setting the script to be started up and started automatically. Therefore, the cloud host can actively establish communication tunnel connection with the preset tunnel server when being started every time.
In one possible embodiment, the tunnel server includes a master tunnel server and a slave tunnel server, where the step of sending the communication tunnel creation request to the preset tunnel server may be implemented by the following steps 41 to 42:
(41) randomly selecting a target tunnel server from the main tunnel server and the slave tunnel servers through a preset load balancer;
(42) a communication tunnel creation request is sent to the target tunnel server.
Here, the process of selecting the target tunnel server through the load balancer may refer to the corresponding content of the foregoing embodiment, and is not described herein again.
Step S304: and returning the response result to the management server through the communication tunnel receiving the access request and the tunnel server corresponding to the communication tunnel.
For example, assuming that the access request is to read a certain data a, in one of the response modes, the data a may be returned as a response result, so that the cloud host returns the data a to the management server through the corresponding communication tunnel and the tunnel server. In this way, bidirectional communication between the private cloud host and the management server is achieved.
Taking the application scenario shown in fig. 2 as an example, it is assumed that the cloud host runs the tunnel service after being started, where the tunnel service establishes a tunnel through a 2222 port of the load balancer, and the service running command is as follows:
ssh-N-o'PubkeyAuthentication＝yes'-o'StricHostKeyChecking＝no'-o'UserKnownHostsFile＝/dev/null'-o'ServerAliveInterval＝5'-o'ServerAliveCountMax＝3'-R 127.0.0.1:${vm_port}:127.0.0.1:22kmr_relay@10.172.1.187-p 2222-i～/.ssh/id_rsa_tunnel。
in the above command, remote _ ip indicates a remote server address; remote _ port represents a port to be monitored by a remote end; local _ ip represents a local address, which can be a local address or other hosts; local _ port represents the port to which data is to be forwarded. The meaning of this command expression is: starting a ssh process on a remote host (10.172.1.187), and monitoring 127.0.0.1$ { vm _ port } the remote port; and forwards requests to the 127.0.0.1:22 port of the native (i.e., cloud host) that arrive at the 127.0.0.1: $ { vm _ port } port.
Specifically, the load balancer will randomly distribute the request to the master tunnel server and the slave tunnel servers, if the request is distributed to the master tunnel server node, the Nginx on the master tunnel server receives the request and then forwards the request to the 10.200.0.19:22 port of the master tunnel server; if distributed to the slave tunnel server node, Nginx on the slave tunnel server will forward the request to the 10.200.0.19:22 port of the master tunnel server. After receiving the request, the sshd service on the primary tunnel server initiates a ssh process locally to monitor 127.0.0,1: $ { vm _ port } port, and all data on the port is forwarded to 22 ports on the cloud host.
According to the data communication method provided by the embodiment of the invention, the process that the management server accesses the private cloud host through the tunnel server is described from the private cloud host side, and the method improves the network security of the private cloud host.
In addition, another data communication method is further provided in an embodiment of the present invention, referring to fig. 4, which is a schematic flow chart of another data communication method, where the method is applied to a tunnel server, and a communication tunnel is pre-established between the tunnel server and a target private cloud host. As can be seen from fig. 4, the method comprises the following steps:
step S402: if a communication connection request from a preset management server is received, establishing communication connection with the management server; wherein the management server runs a data distributed processing management service.
In this embodiment, the tunnel server runs a proxy protocol service, and the proxy protocol service is used for the tunnel server to establish a communication connection with the management server. When the tunnel server receives a communication connection request from a preset management server, the tunnel server establishes communication connection with the proxy protocol service on the management server through a preset proxy protocol, wherein the proxy protocol is matched with the proxy protocol service.
In this way, a communication connection between the tunnel server and the management server is established.
Step S404: and if an access request to the target private cloud host from the management server is received, accessing the target private cloud host through the communication tunnel.
In one possible implementation manner, a target port matched with the target private cloud host is preset in the tunnel server, and a communication tunnel is preset between the target port and the target private cloud host. When the tunnel server receives an access request of a management server to a target private cloud host, the tunnel server firstly determines a target port matched with the target private cloud host according to the access request; then, the target private cloud host is accessed through the target port and the communication tunnel.
