The invention discloses a method and a system for realizing the switchover of active and standby servers, which comprises that when the standby switch detects that the main server cannot respond to the second ARP request, the gateway broadcasts the first ARP request again; the IP address of the failed main server is the same The standby server receives the first ARP request, and sends its own MAC address to the gateway via the standby switch and the main switch. The present invention monitors the fault condition of the main server through the standby switch, and realizes that when the main server fails and cannot respond to the second ARP request, the standby server corresponding to the main server is started to respond to the first ARP request, and the main and standby servers are completed. switch between each other. On the one hand, the present invention ensures the compatibility with the existing network service; on the other hand, it simply realizes the switching between the active and standby servers, and does not require the server to have the cluster function. In this way, it not only effectively protects the investment and operation of existing network equipment, but also brings safer and faster data storage guarantee for enterprises.
Description
technical field [0001] The invention relates to a backup technology, in particular to a method and a system for realizing switchover between active and standby servers. Background technique [0002] At present, in the commonly used active and standby solutions, multiple servers are generally required to form a cluster server architecture, such as figure 1 As shown, for example, server S, server S', and server S" serve as a cluster. It is assumed that server S serves as the master server, and server S' and server S" serve as standby cluster servers. The standby cluster servers can be sorted by priority in advance. When the main server fails in a disaster, the switch will start the standby server according to the preset priority order (only one server is active at the same time). Both the master server and the slave server are installed with cluster software to provide a cluster function, and the main function of the cluster software is to perform heartbeat detection between ...
