Referring to fig. 4, fig. 4 is a first embodiment of a configuration synchronization method for dual-computer hot backup according to the present invention, where the configuration synchronization method for dual-computer hot backup includes the following steps:
step S10, the service slave receives the configuration command sent by the service host, and stores the configuration command in a list to be executed, wherein, after the service host performs configuration according to the configuration command, the configuration command is sent to the service slave;
step S20, sequentially acquiring configuration commands of the list to be executed;
and step S30, after the configuration command is acquired each time, performing configuration operation according to the acquired configuration command.
In this embodiment, the configuration command is a computer instruction for configuring a relevant service function in a server; the list to be executed is a data structure used by the service slave to store the received configuration command; the configuration operation may be a computer instruction for controlling a configuration command, such as a modify operation, a confirm operation, and a discard operation.
When receiving a configuration command sent by the service host, the first processor saves the configuration command to a list to be executed in the first memory.
When the service slave machine is configured, the first processor reads the list to be executed stored in the first memory, acquires the configuration command of the list to be executed, and outputs the configuration parameters of the configuration command. And when receiving the control instruction, the first processor controls and executes the configuration operation corresponding to the control instruction for the configuration command.
After the control instruction is based on modification operation triggered by the configuration parameters, the first processor receives modification data, replaces the configuration parameters of the configuration command with the modification data, obtains an updated configuration command, executes the updated configuration command to generate configuration data corresponding to the configuration command, and stores the configuration data in the first memory.
After the execution of the configuration command is finished, the first processor sequentially acquires the configuration command in the list to be executed, and executes the configuration synchronization step.
In the technical solution disclosed in this embodiment, by storing the received configuration command in the list to be executed and then acquiring the configuration command when starting configuration, after the service master executes the configuration command, it is not necessary to switch back to the service master to execute a new configuration command after switching to the service slave to execute the configuration command, so that the switching frequency between the service master and the service slave is reduced, and the effect of improving the configuration synchronization efficiency is achieved.
Optionally, in this embodiment, since the control instruction received by the first processor may be a confirmation operation triggered based on the configuration parameter, after the first processor receives the confirmation operation triggered based on the configuration parameter, the currently acquired configuration command is executed to generate configuration data corresponding to the configuration command, and the configuration data is saved in the first memory.
After the execution of the configuration command is finished, the first processor sequentially acquires the configuration command in the list to be executed, and executes the configuration synchronization step.
In the technical solution disclosed in this embodiment, the technical effect of synchronizing the configuration of the service master and the service slave is achieved by directly executing the configuration command, and then generating and storing the configuration data.
Optionally, in this embodiment, since the control instruction received by the first processor may also be a discarding operation triggered based on the configuration parameter, after the first processor receives the discarding operation triggered based on the configuration parameter, the corresponding configuration commands in the list to be executed are deleted, then the configuration commands in the list to be executed are sequentially acquired, and the configuration synchronization step as described above is executed.
In the technical solution disclosed in this embodiment, by deleting the configuration command, a technical effect of avoiding synchronization unnecessary configuration is achieved.
Optionally, in this embodiment, since the list to be executed acquired by the first processor may be empty, when the first processor does not acquire the configuration command of the list to be executed, the prompt information is output.
In the technical scheme disclosed in the embodiment, the technical effect of prompting errors is achieved by outputting the prompt information.
Referring to fig. 5, fig. 5 is a second embodiment of the configuration synchronization method for dual-computer hot backup according to the present invention, where the configuration synchronization method for dual-computer hot backup includes the following steps:
step S10, when receiving the configuration command, executing the configuration command;
and step S20, when the configuration command meets the preset condition, sending the configuration command to a service slave machine, so that the service slave machine can receive and store the configuration command.
In this embodiment, the preset condition may be that the configuration command is inconsistent with a preset configuration command in the list to be executed; the list to be executed is a configuration command which is received by the service host and sent by the service slave, and the list to be executed is stored in the second memory.
And when receiving the configuration command, the second processor executes the configuration command to generate configuration data corresponding to the configuration command and stores the configuration data in the second memory.
The second processor judges whether a preset configuration command consistent with the configuration command exists in the list to be executed or not, and judges that the configuration command meets a preset condition when the preset configuration command consistent with the configuration command does not exist in the list to be executed; and when a preset configuration command consistent with the configuration command exists in the list to be executed, judging that the configuration command does not meet the preset condition.
When the configuration command meets the preset condition, the second processor sends the configuration command to the service slave, receives a new configuration command, and then executes the configuration synchronization step.
When the configuration command does not satisfy the preset condition, the second processor receives a new configuration command and then executes the configuration synchronization step as described above.
In the technical solution disclosed in this embodiment, the configuration command meeting the preset condition is sent to the service slave, so that the technical effect of synchronizing the configurations of the service master and the service slave is achieved.
In addition, an embodiment of the present invention further provides a service slave, where the service slave includes a memory, a processor, and a configuration synchronization program that is stored in the memory and is executable on the processor, and when the configuration synchronization program is executed by the processor, the steps of the configuration synchronization method for dual-computer hot backup according to the above embodiments are implemented.

In addition, the embodiment of the present invention further provides a dual-computer hot-standby system, where the dual-computer hot-standby system includes a service slave and a service host, and the service slave and the service host are backup to each other.
