Problems solved by technology

[0002] In the existing client-server system, the IP addresses configured by the master server and the slave server are different. When an exception occurs on the master server, when the client accesses the slave server, the IP address of the slave server is different from that of the master server. The end needs to perform related actions such as resending the request to obtain the service from the server, which causes inconvenience to the client to a certain extent

Embodiment Construction

[0012] Please refer to figure 1 , the server system 100 in this embodiment includes a master server 10 and a slave server 20 that execute the same service and are connected to a client 200 (not shown) through an IP network. The master server 10 and the slave server 20 are connected to a switch (not shown). The server system 100 is configured with a working IP address and a backup IP address. In this embodiment, one or more clients establish a communication connection with the server system 100 through the working IP address. Initially, the master server 10 is configured with a working IP address, and the slave server 20 is configured with a backup IP address. When the master server 10 is abnormal, the slave server 20 sends a packet containing IP address switching information to the master server 10, requesting the master server 10 and the slave server 20 to switch IP addresses, the master server 10 is configured with a backup IP address, and the slave server 20 is configured...

Abstract

The invention provides a server system and a server switching method. The server system comprises a master server and a slave server, the server system is configured with a working IP (internal protocol) address and a backup IP address, and the server system performs communication with a client through the working IP address; and the method comprises the following steps of: configuring the working IP address by the master server and configuring the backup IP address by the slave server during the initialization of the server system; and when the slave server detects the abnormity of the master server, sending a package comprising IP address switching information to the master server, requesting the master server to switch the IP address with the slave server, configuring the IP address by the master server and configuring the working IP address by the slave server. When the the master server with abnormity is switched to the slave server, the maser server can exchange the IP address with the slave server, and then the client can still perform communication with the slave server through the working IP address. Therefore, when the master server is abnormal, the client can avoid the situation of business interruption.

Description

technical field [0001] The invention relates to a server system, in particular to a server system including a master / slave server and a master / slave server switching method. Background technique [0002] In the existing client-server system, the IP addresses configured by the master server and the slave server are different. When an exception occurs on the master server, when the client accesses the slave server, the IP address of the slave server is different from that of the master server. The end needs to perform related actions such as resending the request to obtain the service from the server, which causes inconvenience to the client to a certain extent. Contents of the invention [0003] In view of this, the present invention provides a server system and a server switching method to solve the above technical problems. [0004] The server system includes a master server and a slave server. The server system is configured with a working IP address and a backup IP add...
