In the method for server reverse communication and management provided by the embodiment of the present invention, by using the CMSP function deployed on the management end server and each remote server, even if the remote server does not provide a public network IP address, which results in that SSH and other manners cannot establish connection for use, the remote server can perform communication connection with the management end server through reverse communication, so as to achieve the purpose of managing the remote server by the management end server, and the security of message data transmission is high.
Further, in a specific implementation, in the method for reverse server communication and management provided by the embodiment of the present invention, each remote server is configured with an IP address and an access port of an accessible management server; the management server communicates with the remote server by invoking a messaging application interface, which is shown in fig. 2.
In specific implementation, in the method for reverse server communication and management provided in the embodiment of the present invention, after the step S104 of obtaining the management instruction message by the remote server is executed, the method may further include: and the remote server performs security check on the acquired management instruction message, and starts to execute the management instruction message when the security check is passed. Specifically, after receiving an instruction message, an agent program of the remote server firstly checks the security of the received instruction, the instruction is executed on the remote server after the security check is passed, the agent program generates an instruction execution result message after the instruction execution is finished, and the result message is sent to the management side server through the established CMSP communication connection.
In specific implementation, in the method for reverse server communication and management provided in the embodiment of the present invention, the method may further include: the management end server acquires a result message by monitoring a topic port for executing a return message by an instruction; the management end server analyzes and processes the result message; if the result message is abnormal, performing an abnormal processing step; if the result message is normal, the instruction issuing execution process is finished.
In specific implementation, in the method for reverse communication and management of a server provided in the embodiment of the present invention, after the remote server is started in step S102, a communication connection is established between the remote server and the management server in a reverse direction, as shown in fig. 3, specifically, the method may include: after the remote server is started, an agent program of the remote server automatically creates a sending topic with the name of agent _ send _ topic and a receiving topic with the name of agent _ receive _ topc, wherein the agent _ receive _ topc establishes reverse connection with the sending topic of the management end server through a cmsPRS, and the agent _ send _ topc establishes connection with the receiving topic of the management end server through a cmsPRS. That is, the cmspRS function and the cmspSN function of the CMSP are used in the remote server, and the cmspRS and the cmspSN function enable the remote server to establish a communication connection with the management server in a reverse direction after being started.
Further, in specific implementation, in the method for reverse communication and management of a server provided in the embodiment of the present invention, after the remote server is started in step S102, a communication connection is established between the remote server and the management server in a reverse direction, as shown in fig. 3, specifically, the method may further include: the remote server sends a registration message to a registration receiving server of the management server through registering the topic with the name agent _ common _ topic, wherein the name of the topic is cloud _ common _ topic; after the management server receives the registration message, the information of the remote server is registered and recorded, a registration success message is returned, and a sending topic and a receiving topic corresponding to the remote server are created. The sending topic naming rule created by the manager server may be the number of agent _ send _ topic _ + remote server, and the receiving topic naming rule may be the number of agent _ receive _ topic _ + remote server. And the management end server sends an instruction to the remote end server and receives an instruction execution result message through the sending and receiving topic.
In specific implementation, in the method for reverse server communication and management provided by the embodiment of the present invention, as shown in fig. 4, a program run by the remote server includes three parts, namely, a management CMSP, an agent program, and a third-party application. The management CMSP is used for communicating with the management server. The message content is a management instruction to the remote server, consumed by the agent. The management CMSP may be integrated into the agent using a standard version. The agent program is used for receiving the management end server information from the management CMSP and carrying out the functions of third-party application installation and deployment, starting, stopping, configuration file modification and the like on the remote server. The agent may be developed in the C + + language. The CMSP is only responsible for message transmission, and when the CMSP message is transmitted to a remote server, a corresponding program is required to consume the message and perform management operation according to the message content, so that the received message needs to be executed and processed at an agent program, and the management of third-party application is realized. The third-party application can be managed by the management-side server, the operation instruction is transmitted to the remote server through CMSP communication, and management operations such as installation, starting, stopping, uninstalling, configuration file modification and the like are carried out by the agent program.
It should be noted that, in order to ensure that the management server and the agent program can correctly construct and analyze the message, a byte stream format exchange standard needs to be defined, and json is used as a main format in the byte stream.
The format is as follows:
| MsgType | MsgContent | other messages |
The delimiters are: 0
Wherein, each field information is as follows:
in addition, it should be noted that because the present invention uses CMSP for message transmission, sending and replying messages is an asynchronous process. To ensure the operation experience of the management server user, as shown in fig. 5, the code logic adopts a pseudo-synchronous mode, that is, after sending a message, the program waits for receiving a reply message, receives and processes the reply message, and returns a result, which is a complete process.
