Nginx 反向代理，负载均衡

方向代理：

修改nginx的配置文件 

    upstream tomcatS{
        server http://144.34.134.37:8080;
        server http://144.34.134.37:8081
    }

    server {
        listen       88;
        server_name  localhost;

        #charset koi8-r;

        #access_log  logs/host.access.log  main;

        location / {
            proxy_pass   tomcatS;
            index  index.html index.htm;
        }
    }

负载均衡：

添加权重weight，默认为1，越高处理的越多

	upstream tomcatS{
        server http://144.34.134.37:8080 weight=2;
        server http://144.34.134.37:8081;
    }

    server {
        listen       88;
        server_name  localhost;

        #charset koi8-r;

        #access_log  logs/host.access.log  main;

        location / {
            proxy_pass   tomcatS;
            index  index.html index.htm;
        }
    }
