and S11, monitoring the change condition of the related state of the cluster equipment.
In the embodiment of the invention, the master/standby control center switches the master/standby state of the cluster equipment according to the change condition of the relevant state of the cluster equipment. Therefore, the master and standby control centers monitor the change condition of the relevant state of the cluster equipment in real time.
And S12, switching the main and standby states of the cluster equipment according to the monitored change condition of the relevant state of the cluster equipment.
In the embodiment of the invention, the master and standby control centers monitor the change condition of the relevant state of the cluster equipment in real time. And the master/standby control center switches the master/standby states of the cluster equipment according to the monitored change condition of the relevant state of the cluster equipment. For example, when the master/backup control center monitors that the process of the host in the cluster device is terminated, the host is switched to the backup, and the drift IP is deleted. If the master-backup control center monitors that the network card of the backup computer in the cluster equipment can work normally from abnormal work, the backup computer is switched to the host computer.
According to the embodiment of the invention, the main/standby states of the cluster equipment are switched according to the change condition of the relevant state of the cluster equipment, so that the switching real-time performance is ensured; and multi-machine hot standby is adopted, and the condition of switching the cluster equipment is monitored in real time, so that the switching reliability is ensured.
Further, on the basis of the above method embodiment, the cluster device correlation state includes: network card state, interface state, process state of the cluster equipment and/or heartbeat connection state among the cluster equipment.
In the embodiment of the present invention, the relevant states of the cluster device include a network card state, an interface state, a process state of the cluster device, and/or a heartbeat connection state between the cluster devices. The network card state of the cluster equipment is divided into a normal working state and an abnormal working state; the interface state of the cluster equipment is divided into a connection intact state and an interface fracture state; the process state of the cluster equipment is divided into a non-termination state and a termination state; the heartbeat connection state among the cluster devices is divided into a heartbeat connection intact state and a heartbeat connection failure state.
The cluster equipment related state in the embodiment of the invention provides a basis for the subsequent switching of the main and standby states of the cluster equipment. .
Further, on the basis of the above method embodiment, before monitoring a change condition of a relevant state of the cluster device, the method for switching between active and standby states of the cluster device further includes:
setting an initial master/standby state of the cluster equipment according to the current network card state, interface state, process state and/or heartbeat connection state among the cluster equipment;

and deleting the drift IP on the network card of the standby machine under the condition that the initial main/standby state of the cluster equipment is the standby machine.
In the embodiment of the present invention, before monitoring a change condition of a relevant state of cluster equipment, an initial active/standby state of the cluster equipment needs to be set according to a current network card state, an interface state, a process state and/or a heartbeat connection state between the cluster equipment; for example, if the current network card state of the cluster device is capable of working normally, the interface state is in a good connection state, the process state is in a non-termination state, and the heartbeat connection state between the cluster devices is in a good heartbeat connection state, setting the initial master/standby state of the cluster device as a host; if the current network card state of the cluster equipment is abnormal, the interface state is broken, the process state is terminated and/or the heartbeat connection state between the cluster equipment is failed, setting the initial main/standby state of the cluster equipment as a standby machine.

The interface state in the embodiment of the invention can be used as a basis for judging the main/standby state of the cluster equipment.
Further, on the basis of the above method embodiment, after the switching of the master/slave states of the cluster device is performed according to the monitored change condition of the relevant state of the cluster device, the method for switching the master/slave states of the cluster device further includes:
deleting the drift IP of the host under the condition that the main/standby state of the cluster equipment is switched from the host to the standby;
and under the condition that the main/standby state of the cluster equipment is switched from the standby machine to the host machine, adding the drift IP to the standby machine.
In the embodiment of the invention, the host is switched into the standby machine, and the drift IP of the host needs to be deleted; the standby machine is switched to the host machine, and a drift IP needs to be added to the standby machine. Specifically, after the main/standby state of the cluster equipment is switched according to the monitored change condition of the relevant state of the cluster equipment, under the condition that the main/standby state of the cluster equipment is switched from a host to a standby machine, the drift IP of the host is deleted; and under the condition that the main/standby state of the cluster equipment is switched from the standby machine to the host machine, adding the drift IP to the standby machine.
According to the embodiment of the invention, the automatic addition and deletion of the drift IP are realized according to the switching of the main and standby states of the cluster equipment.

In the embodiment of the invention, before the change condition of the relevant state of the cluster equipment is monitored, the initial master/standby state of the cluster equipment is set according to the current relevant state of the cluster equipment. Specifically, the initial master/standby state of the cluster device is set as a standby machine under the condition that the current network card state of the cluster device is abnormal, the interface state is broken, the process state is terminated and/or the heartbeat connection state between the cluster devices is failed.
The embodiment of the invention sets the initial main/standby state of the cluster equipment by monitoring the relevant state of the cluster equipment, and provides a basis for the subsequent switching of the main/standby state of the cluster equipment.
Further, on the basis of the above method embodiment, the setting an initial active/standby state of the cluster device according to a current network card state, an interface state, a process state of the cluster device, and/or a heartbeat connection state between the cluster devices further includes:
and setting the initial main and standby states of the cluster equipment as a host under the conditions that the current network card state of the cluster equipment can work normally, the interface state is in good connection, the process state is non-termination and the heartbeat connection state between the cluster equipment is in good heartbeat connection.
In the embodiment of the invention, before the change condition of the relevant state of the cluster equipment is monitored, the initial master/standby state of the cluster equipment is set according to the current relevant state of the cluster equipment. Specifically, the initial master/standby state of the cluster device is set as the host under the condition that the current network card state of the cluster device is capable of working normally, the interface state is in good connection, and the process state is non-terminated and the heartbeat connection state between the cluster devices is in good heartbeat connection.
The embodiment of the invention sets the initial main/standby state of the cluster equipment by monitoring the relevant state of the cluster equipment, and provides a basis for the subsequent switching of the main/standby state of the cluster equipment.
The above is an introduction of the method for switching the active/standby states of the cluster device.
It should be noted that, whether the host is switched to the standby host or not may also be determined by the following parameters, such as special parameters, interface and process parameters, and priority parameters. In practical application, the special parameters are preferentially compared, the interface and process parameters are secondarily compared, and the priority parameters are compared again. If the local cache has no host and the local has the condition of becoming the host, the local is promoted to be the host. When the network card is switched reversely automatically, the host computer is switched to the standby computer, the redundancy time needs to be considered, namely when some equipment monitors that the host computer is not in the cache and the parameters of the local computer are not suitable for serving as the host computer, at the moment, if the network card cannot work normally, the network card is switched to the standby computer immediately; if the judgment condition is that the external interface and the process state wait for a plurality of periods, the parameters received in a plurality of continuous periods point to the host machine and are not suitable for serving as the host machine, and the specific period parameters are determined by configuration, the host machine is reduced to a standby machine. And after the success, the state packet broadcast is immediately sent to inform the standby machine to switch the host. The redundant time is not needed to be considered when the host computer is upgraded from the standby computer to the host computer, and if the host computer is suitable and the host computer does not exist in the cache, the host computer is upgraded to the host computer immediately. If the local computer is the host computer, if the host computer exists in the cache, the equipment with low priority is immediately reduced to the standby computer through priority judgment. If a scene exists, double hosts appear in the environment due to some reason, due to the problems of time delay and the like, the two hosts both monitor that the other host exists in the cache, and the priority is judged to be reduced to a standby host.
Next, a master/slave state switching device of the cluster device is introduced.
