使用NGINX在Nginx负载平衡上检查服务IIS

Question

I setup load balancing with nginx. Here is my config

upstream mywebsite1  {
  least_conn;;
  server xxx.xxx.xxx.20 weight=1 max_fails=3 fail_timeout=15s;
  server xxx.xxx.xxx.21 weight=1 max_fails=3 fail_timeout=15s;
}

Default all request sent to 2 sever backend. Now if IIS Service in Backend1 (xxx.xxx.xxx.20) down, Access to website will be interrupted. So how can make all request auto connect to backend2 when IIS service on backend1 down, or connect to backend1 when IIS service on backend2 down ???

Thanks!

Answer 1

You are setting max_fails=3 for each server, so try to seventh requests to the nginx load balancer while server .20 is being down.

You can refer this : http://nginx.org/en/docs/http/load_balancing.html
