The master-slave management method of the server cluster can acquire the communication addresses of all the server units in the server cluster, realize communication with each server unit according to the server units corresponding to the communication addresses, and control each server unit to be in a first state according to the communication instructions. Specifically, the first state may be an isolated state, and the server unit in the isolated state stores only the current isolated state of the server unit and clears the cascade state of the server unit. The method can also control the server units to acquire the identity authentication information, monitor the acquisition state of each server unit for the identity authentication information, and execute one of the following steps according to the acquisition state of the identity authentication information: if the monitoring result shows that the server unit receives the identity authentication information, controlling the server unit which correspondingly acquires the identity authentication information to adjust to a slave server state, and taking the server unit which acquires the identity authentication information as a slave server; or if the monitoring result shows that the part of server units do not acquire the identity authentication information under the preset first condition, the part of server units which do not acquire the identity authentication information are brought into the server set to be processed, and host selection is performed on all servers in the server set to be processed, so that the server units in the server set to be processed are classified, and a master server and a slave server are generated.

and controlling the master server to output the first heartbeat message to the slave server.
The method can control the slave server to automatically change the working state of the slave server according to the acquired first heartbeat message by outputting the first heartbeat message to the slave server. Specifically, when the slave server receives the first heartbeat message output by the master server, the slave server may determine that the slave server itself is still in a connection state with the master server, control the working state of the slave server according to the current connection state to be in the slave server state, and receive information output by the master server. In some specific embodiments, after receiving the first heartbeat message output by the master server, the slave server synchronizes the local cascade information according to the first heartbeat message, and stores the synchronized local cascade information into the slave server. By the method, the master server can detect and control the working state of the slave servers, so that the slave servers connected with the master server in the whole server cluster are controlled.
In some embodiments, referring to fig. 2, the method further comprises:

Specifically, initialized cascade information is pre-stored in each server unit, when a certain server unit is adjusted to a main server state through host election, and after the server unit is used as a main server, the method changes the cascade information of the main server, namely, the cascade information of the host is updated according to a second heartbeat message output from the server, and first cascade information is generated according to the updated cascade information. By the method, the master server can effectively synchronize the slave server information which is in communication interaction with the master server in the current server cluster, so that the effect of automatically controlling the slave servers through the master server can be achieved, and the difficulty of a server cluster management method is effectively reduced.

Specifically, under a preset second condition, the master server may process a third heartbeat message output by the slave server which performs communication interaction with the master server, compare the third heartbeat message with a second heartbeat message obtained by the master server after the host computer is elected, obtain a slave server still connected in the server cluster network currently according to a comparison result, screen the slave server leaving the server cluster network through the second heartbeat message, and update current first cascade information of the master server according to a screening result. According to the method, the master server can acquire the slave servers in the current server cluster network in real time, and update the first cascade information stored in the master server according to the connection state of the slave servers in the current server cluster network, so that the management of the master server on the slave servers is realized, and meanwhile, the connection state of the slave servers in the server cluster can be clarified, so that the simple and efficient control of the server cluster is realized.

The method can change the master-slave relation of the servers in the server cluster, thereby changing the master server and improving the control flexibility of the cluster servers; and the master server state and the slave server state of the server are automatically changed through the acquisition state of the server unit for the identity authentication information, so that the control of the server cluster can be realized more conveniently and simply.

and if the slave server does not send the second heartbeat message or does not receive the first heartbeat message under the preset third condition, the state of the slave server is adjusted to the first state.
The method can control the slave server to monitor the acquisition state of the first heartbeat message and the acquisition state of the second heartbeat message under a preset third condition, and when the fact that the second heartbeat message is not sent or the first heartbeat message is not received is detected under the preset third condition, the corresponding slave server is judged to have left the server cluster network. In order to reduce the management load of the server cluster, the method can adjust the working state of the corresponding slave server to the first state, so as to avoid the slave server which does not send the second heartbeat message or does not receive the first heartbeat message from occupying redundant resources.

s810, acquiring first cascade information of a main server;
s820, generating second cascade information of the target main server according to the first cascade information;
s830, synchronizing the second cascade information to the target main server.
