Add a health check to the upstream added in the nginx.conf configuration file as follows:

uptream Name {         192.168.  0.21:         192.168. 0.22:        Check interval= rise=2 fall=5 timeout= + type=http;         } #上面配置的意思是, for the name of all nodes in this load balancer entry, each 3 second detection of a capital, request 2 under the normal flag realserver state is up, if the detection of 5 failed, then the status of the Mark Realserver is down, the timeout is 1 seconds.
