1)编辑vi nginx.conf,找到http{} 在里面加入

    

    upstream ucentertomcat {

    server 192.168.100.108:8080 weight=1;

    server 192.168.100.105:8080 weight=1;

    server 192.168.100.106:8080 weight=1;

    }

    在server{}里面加入

    

    location /ucenter {

            proxy_pass   http://ucentertomcat;

            index  index.html index.htm;

    }
