使用nginx最大的好处就是负载均衡。

#设定负载均衡的服务器列表
    upstream service{
        server 10.4.29.174:7477;
    }

server {
        listen       80;

        #access_log /data/logs/access.temp.log all;
        access_log off;
        error_page   500 502 503 504  /50x.html;
        location = /50x.html {
            root   html;
            }

location /v2 {
                proxy_pass http://service;    #请求转向service定义的服务器列表
