Embodiment Construction

[0012] In order to make the purpose, technical solutions and advantages of the present invention clearer, the implementation of the present invention will be further described in detail below in conjunction with the accompanying drawings:

[0013] see figure 1 , the present embodiment provides a method for service takeover of a multi-host system, the method comprising the following steps:

[0014] Step 101 sets the state of the standby host system to the protection state.

[0015] Step 102 records the flag, and simultaneously sets all services of the standby host system to a protected state.

[0016] In step 103, after setting the system and service to the protected state, take over the public network protocol address of the failed host to provide external services.

[0017] Step 104 judges whether the service to be taken over needs to perform service takeover environment preparation.

[0018] Step 105 If not needed, take over the service immediately.

[0019] Step 106 per...

Abstract

The invention discloses a service takeover method for a multi-host system, and the method essentially includes that an external network protocol address of a service host, which provides external services, is taken over to one standby host, and then the service of the service host is prepared to be taken over to a service environment required by the standby host and a ready condition of the service environment is detected. Before unpreparation, data packets accessed by an external network protocol location address to the service are discarded. By adopting the service takeover method of the invention, a continuous network protocol address of the multi-master processor system as well as continuous services can be realized.

Description

technical field [0001] The invention relates to a takeover technology between host systems, in particular to a service takeover method of a multi-host system. Background technique [0002] At present, almost all the services provided by the host can be realized through the network, and it is only possible to provide services through the network to realize the uninterrupted switching of services among multiple hosts in the host system. However, the nature of the services provided externally through the public network protocol address is different, so whether the service is available after the network protocol address is taken over is also different. For example, some services can be provided immediately after the address of the network protocol is taken over, such as: DHCP protocol, DNS, and HTTP services. These services can be started with a configuration as small as the original failed host, that is, they can provide services without interruption. [0003] Conversely, file...
