[0023] A system for receiving and handling alarms based on B / S architecture, the specific implementation is as follows:
[0024] (1) Including at least 4 servers, Linux A and B, and Linux C and D; keepalived is installed on Linux A and B to realize virtual IP, keepalived on both Linux A and B servers point to the same virtual IP , and perform two-way heartbeat detection;
[0025] (2) A is configured as the host and takes over the virtual IP. At this time, B is used as the backup machine. When A server is shut down for maintenance or downtime, keepalived on B will automatically take over the virtual IP to ensure that the service is available;
[0026] (3) Nginx is installed on Linux A and B to achieve load balancing. The two Nginx configurations are similar, and they are both configured as reverse proxy for the lower-level tomcat server;
[0027] (3) The balance strategy is configured as IP hash to maintain the session of the client and the police service; the static resources...
