Abstract

A highly available server system based on cloud computing comprises a central control management server, a cloud host server, a storage server and at least one application server; the central control management server is connected with at least one application server, and configured to respectively monitor at least one application server, if detecting that there exists an application server in the fault state among the at least one applications server, then the central control management server sends a first instruction message; the cloud host server is connected with the central control management server, and configured to receive the first instruction message, and call the target virtual machine image file from the storage server according to instructions of the first instruction message, and run the target virtual machine image file; the storage server is configured to store the corresponding virtual machine image file of at least one application server.

Claims

1. A highly available server system based on cloud computing, comprising:

a central control management server, a cloud host server, a storage server and at least one application server;

wherein;

the central control management server is connected with the at least one application server, and configured to respectively monitor the at least one application server, if detecting that there exists an application server in the fault state among the at least one application server, then the central control management server send a first instruction message to the cloud host server;

the cloud host server is connected with the central control management server, and configured to receive the first instruction message sent by the central control management server, and call a target virtual machine image file from the storage server according to the first instruction message, and run the target virtual machine image file;

wherein the target virtual machine image file is a target virtual machine image file corresponding to the application server in the fault state; and

the storage server is connected with the cloud host server, and configured to store the virtual machine image file corresponding to the at least one application server, for the cloud host server to call the target virtual machine image file of the virtual machine image file.

2. The highly available server system based on cloud computing according to claim 1, wherein the central control management server is further configured to:

when detecting that the application server in the fault state has already returned to a normal state, send a second instruction message to the cloud host server;

the cloud host server is further configured to receive the second instruction message, and stop running the target virtual machine image file according to the second instruction message.

3. The highly available server system based on cloud computing according to claim 1, wherein the central control management server comprises:

a monitoring module, configured to respectively monitor the at least one application server, acquire monitoring result, and send the monitoring result to a first transceiver module;

the first transceiver module, configured to receive the monitoring result sent by the monitoring module, and when the monitoring result indicates that there exists an application server in the fault state among the at least one application server, send the first instruction message to the cloud host server;

the cloud host server comprises;

a second transceiver module, configured to receive the first instruction message sent by the first transceiver module, and call the target virtual machine image file from the storage server according to the first instruction message, and send the target virtual machine image file to a running module; and

the running module, configured to receive the target virtual machine image file sent by the second transceiver module, and run the target virtual machine image file.

4. The highly available server system based on cloud computing according to claim 2, wherein the central control management server comprises:

a monitoring module, configured to respectively monitor the at least one application server, acquire monitoring result, and send the monitoring result to a first transceiver module;
