In the master-standby mode, one of the two devices is a host and the other is a standby, the host provides firewall service, the standby is in a monitoring state, and the standby replaces the host to provide firewall service when detecting the host fault. In the dual-master mode, the two devices are mutually master and standby and are both in an active state, so that load balance is realized, and when one device fails, the other device takes over.
In the process of upgrading the dual-computer hot-standby system, in order to upgrade two devices one by one, firstly, the working mode of the dual-computer hot-standby system is set to be a main standby mode, at the moment, the host provides service, and the standby machine is in an idle state and can be upgraded.

in this step, the working mode of the dual-computer hot-standby system is the main-standby mode, the host provides services, the standby computer is in the idle state, the standby computer can be upgraded, and the main-standby switching is performed after the upgrade is successful, so that the upgraded standby computer serves as the current host of the dual-computer hot-standby system to provide services, and the original host is in the idle state.
S104: and upgrading the host, and adding the upgraded host into the dual-computer hot standby system as a current standby computer after upgrading is finished.
In this step, the original host (i.e. the current standby) of the dual-computer hot-standby system is upgraded, and after the upgrade is completed, the upgraded host is taken as the current standby and added to the dual-computer hot-standby system. Preferably, in the upgrading process, the states of the two devices can be recorded in real time, so that a user can monitor the upgrading process of the main and standby machines in real time.
The upgrade method for the dual-computer hot-standby system provided in the embodiment of the present application adds an upgrade state to the dual-computer hot-standby system, where in the upgrade state, a heartbeat line between the host and the standby is only used for information transmission, and the host and the standby do not perform master-slave switching or perform synchronous operations such as routing and session. Therefore, in the upgrading state, the effects of disabling the dual-computer and removing the dual-computer environment are achieved, and the dual-computer environment in the upgrading state does not influence the single-computer upgrading. Therefore, the method for upgrading the dual-computer hot-standby system provided by the embodiment of the application can realize the upgrading of the dual-computer hot-standby system by setting the upgrading state on software on the premise of not changing the hardware environment, and simplifies the operation and maintenance process of the dual-computer hot-standby upgrading.
The embodiment of the application discloses an upgrading method of a dual-computer hot standby system, and compared with the previous embodiment, the embodiment further explains and optimizes the technical scheme. Specifically, the method comprises the following steps:
referring to fig. 2, a flowchart of an upgrade method for a dual-computer hot-standby system according to an exemplary embodiment is shown, and as shown in fig. 2, the method includes:
s201: setting the working mode of the dual-computer hot standby system to be a main standby mode; the dual-computer hot-standby system comprises a host and a standby computer, and the host provides service for the dual-computer hot-standby system in the main-standby mode;
s202: setting any one of the host computer and the standby computer to be in an upgrading state, so that the any one of the host computer and the standby computer can send state information to the other one of the host computer and the standby computer through the heartbeat wire, and the other one of the host computer and the standby computer can be set to be in the upgrading state;
in this embodiment, the synchronization of the upgrade state is realized by using the heartbeat line between the host and the standby machines, and after receiving the upgrade command, any one of the host and the standby machines switches to the upgrade state and forwards the state information of the upgrade state to the other party through the heartbeat line, and after receiving the state information, the other party switches to the upgrade state, and the synchronization of the upgrade state of the host and the standby machines is realized.
S203: upgrading the standby machine, and sending a main-standby switching command to the host machine and the upgraded standby machine after upgrading is completed so that the upgraded standby machine serves as the current host machine;
preferably, before the master-slave switching command is sent to the host and the upgraded slave, the method further includes a step of detecting whether the upgraded slave operates normally, so as to ensure that the slave is upgraded successfully. Correspondingly, the upgrading of the standby machine sends a main-standby switching command to the host machine and the upgraded standby machine after the upgrading is finished so that the upgraded standby machine provides service, and the method further comprises the step of detecting whether the dual-machine hot-standby system operates normally or not so as to ensure that the main-standby switching is successful.
S204: and upgrading the host, and adding the upgraded host into the dual-computer hot standby system as a current standby computer after upgrading is finished.
S205: and resetting the working mode of the dual-computer hot standby system.

As a feasible implementation manner, after the host is upgraded, the working mode of the dual-host hot-standby system, that is, the active-standby mode, is automatically recovered. The step of resetting the working mode of the dual-computer hot standby system after the upgrade is completed comprises the following steps: and when the host machine and the standby machine are detected to be upgraded completely, restoring the working mode of the dual-machine hot standby system to be the main standby mode. Specifically, after the original host is upgraded successfully, the upgrade state is exited, the current working mode is determined to be the main/standby mode, and the current working mode is synchronized to the current host (original/standby) through the jumper wire.
As another possible implementation manner, after the host is upgraded, the operating mode of the dual-computer hot-standby system may be manually set, that is, the step of resetting the operating mode of the dual-computer hot-standby system after the upgrade is completed includes: and after the upgrade is finished, receiving a mode switching command, and resetting the working mode of the dual-computer hot standby system according to the mode switching command. Specifically, the step of setting the working mode of the current standby machine according to the mode switching command, and synchronizing the working mode of the current standby machine to the current host machine through a heartbeat line, that is, resetting the working mode of the dual-machine hot standby system includes: setting the working mode of the current standby machine in the dual-machine hot standby system according to the mode switching command, and sending a mode synchronization command to the current host machine through the current standby machine so as to set the working mode of the current host machine
Therefore, in the embodiment, the upgrading state is synchronized through the heartbeat line between the host and the standby machine, and when the dual-machine hot standby system is in the upgrading state, the heartbeat line is only used for transmitting information, so that the host and the standby machine cannot perform master-slave switching, and cannot perform synchronous operations such as routing and session. Therefore, in the upgrading state, the effects of disabling the dual-computer and removing the dual-computer environment are achieved, and the dual-computer environment in the upgrading state does not influence the single-computer upgrading. Therefore, the embodiment can realize the upgrading of the dual-computer hot standby system by setting the upgrading state on the software on the premise of not changing the hardware environment, and simplifies the operation and maintenance process of the dual-computer hot standby upgrading.
An application embodiment provided by the present application is introduced below, specifically, an upgrade state is newly added in a firewall dual-standby system, after the dual-standby system enters the upgrade state, the firewall dual-standby system is maintained in a main standby mode, and a heartbeat line in the upgrade state maintains basic state information to obtain, and state synchronization such as main standby fault switching, conversation, configuration, and the like is not performed. After the upgrade is finished, the upgrade mode is exited, and the dual-computer hot standby is recovered to be normal.
A specific workflow is shown in fig. 3, and may include the following steps:
the method comprises the following steps: switching the firewall equipment into a main standby mode to ensure that only one host is in a normal working state;
step two: setting an upgrading mode, setting equipment at a standby machine (or a host machine) end to enter the upgrading mode, and synchronizing the state to the host machine (or the standby machine) through a jumper wire, so that the main and standby machine equipment can synchronously enter the upgrading state;
in the upgrading state, automatic switching between the main and standby devices is avoided, synchronous operations such as configuration, routing, conversation and the like are also avoided, and only some simple information state interaction is carried out;
step three: carrying out system upgrade on the standby machine, and observing whether the equipment runs normally or not after the upgrade is finished;
step four: performing primary and standby switching, and switching the service to the upgraded standby machine;
step five: observing whether the service operation is normal;
step six: carrying out system upgrade on an original host (a current new standby machine);
step seven: after the upgrade is finished, the system detects that the upgrade is finished and automatically closes the upgrade state. The main/standby machine hot-standby working mode is recovered to normal, or manual closing can be selected, and the operation of closing the upgrading state is synchronized to equipment at the other end through a heartbeat line, and the main/standby machine hot-standby working mode is recovered to normal;
step eight: renegotiation between the main and standby machines and entering a stable state
