Below by specific embodiment, the present invention program is described in detail.
See Fig. 2, be server backup method flow diagram in one embodiment of the present invention:
Step 201: each standby server adds backup server cluster.
Separate unit standby server adds backup server cluster can not carry out any configuration, can specify the IP address of existing any standby server in backup server cluster when follow-up standby server adds backup server cluster, standby server 2 sets up backup pool relation by communication connection and standby server 1.Standby server 1 and standby server 2 according to pre-conditioned, can elect a standby usage server, as elected a standby usage server according to IP address size, if IP address greatly, are standby usage server.Certain standby server also can according to MAC Address size election standby usage server, and the application does not limit pre-conditioned content.
When standby server N (N is greater than 2) adds backup server cluster, specify the IP address of existing any standby server in backup server cluster, such as standby server 2.
Standby server N attempts to establish a communications link with standby server 2, if but standby server 2 is not standby usage server, then standby server N can be informed in the IP address of standby usage server.
Standby server N and standby usage server establish a communications link.After establishing a communications link, standby server N can compare according to pre-conditioned with standby usage server, if standby server N meets pre-conditioned, then can replace standby usage server updating is new standby usage server.The address information of new standby usage server is notified existing standby server in backup server cluster, to make existing standby server and new standby server establish a communications link by former standby usage server.
Repeat said process and can add some standby servers to backup server cluster, and elect standby usage server.
After electing standby usage server, the address information of each standby server can be notified the address information of all the other standby servers by standby usage server.
Wherein, role's software of various role server is provided with in each standby server.
Step 202: standby usage server is set up and is connected with the heartbeat between multiple master server.
Step 203: standby usage server connects the configuration information obtaining multiple master server by heartbeat.
The service that the master servers such as the configuration information of master server can comprise: the user list that master server is current, management equipment list run.Such as, if master server is VM server, configuration information can comprise the list of devices of the current user list of VM and management, the list of devices of management comprises the IPC (IPCamera being registered to VM, web camera), NVR (NetworkVideoRecorder, network video recorder) equipment, DVR (DigitalVideoRecorder, DVR), the information such as MS, DM, BM, DA.Other role servers also have oneself configuration information, and set up heartbeat at standby usage server and each master server and be connected to, each master server can by the configuration information real-time synchronization of self to standby usage server.
Step 204: standby usage server, by the communication connection of having set up, sends the configuration information of each master server to other standby servers.
Step 205: when certain master server breaks down, according to the hardware asset information of the master server broken down, standby usage server can judge whether described standby usage server meets backup condition.
Be connected because standby usage server establishes heartbeat with each master server, can detect by heartbeat checking the server broken down.The hardware asset information of standby usage server detection self, and judge that can standby usage server meet backup condition according to the hardware asset information of the server broken down, if the hardware resource of standby usage server is not less than the master server broken down, then meet backup condition, otherwise do not meet.If met, then perform step 206, if do not met, perform step 207.
Step 206: role's software of the master server broken down described in operation, and according to the configuration information of the described master server broken down, the service of the master server broken down described in operation.
Role's software of the master server of standby usage server fail, and run corresponding service according to the configuration information of the master server broken down of current preservation, complete the process that standby server upgrades to master server.

Standby usage server is according to the hardware asset information of self, and can the hardware asset information of the server broken down be determined to need how many standby servers meet backup condition, according to the number of units N of required standby server, N-1 platform standby server is selected, the service of the master server broken down described in N platform standby server runs jointly in backup server cluster.Such as, if standby usage server is VM server, and the server broken down is MS server, then can determine that needs two standby servers meet backup condition, now standby usage server can select a standby server in backup server cluster, and the configuration information of MS server according to current preservation, that will run is divided into two parts, two standby servers run MS role server software respectively, and load a configuration information, the master server broken down is backed up by two standby servers.
Step 208: the communication connection between release and other standby servers, and release is connected with the heartbeat between other master servers.
While standby usage server updating is master server, the heartbeat disconnected between other master servers connects, and also disconnects the communication connection between other standby servers.
After disconnecting the communication connection between other standby servers, other standby servers can according to the operation election standby usage server of step 201, and new standby usage server performs the operation of original standby usage server, sets up heartbeat be connected with master server.
Step 209: the server broken down can judge whether to deteriorate to standby server according to fault message.
After some server fail, some hardware resource also can use, and can determine whether the server broken down can deteriorate to standby server in this case according to fault message.Such as, break down if the fault of MS server is single network interface card, according to this fault message, MS server cannot provide enough bandwidth to carry out resource forwarding, but its cpu resource still can be used, now MS server can be degenerated to the standby server of single VM role.If so, then step 210 is performed.
Step 210: if obtain the address information of any one standby server from the information list of standby server.
Because the information list of standby server is sent to each master server by heartbeat connection by standby usage server, the information list of this standby server in the master server therefore broken down, can be stored.
The master server broken down can obtain the address information of each standby server from the information list of this standby server.
Step 211: according to described address information, sets up the communication connection between corresponding standby server, to add the backup server cluster at described standby server place.
The master server broken down adds the process of standby server can refer step 201, if the standby server that namely address information is corresponding is the standby usage server in backup server cluster, after then establishing a communications link with standby usage server, identify the master server broken down and add backup server cluster; If standby server corresponding to address information is not the standby usage server in backup server cluster, the standby server that then address information is corresponding sends the address information of standby usage server to the master server broken down, to make the master server that breaks down set up communication connection between standby usage server, add backup server cluster.
After the master server broken down adds described backup server cluster, pre-conditionedly to compare according to certain with standby usage server, if the master server broken down meets pre-conditioned, the master server then broken down upgrades to the standby usage server in server cluster, after upgrading to standby usage server, the communication connection between other standby servers can be set up, and set up and be connected with the heartbeat between other master servers, and connected the configuration information obtaining other master servers by heartbeat.
