Nginx端口负载

upstream www.abc.com {
    server localhost:7001 weight=1;
    server localhost:7002 weight=1;
    }
server {
        listen       80;
        server_name  localhost;
        location / {
            root   html;
            index  index.html index.htm index.php;
            proxy_pass        http://www.abc.com;
            proxy_set_header  X-Real-IP  $remote_addr;
        }
}
server {
        listen       7001;
        server_name  localhost;
        location / {
            root   html;
            index  index.html index.htm index.php;
　　　　　　  proxy_pass http://localhost:7001;　
        } 
}
server {
        listen       7002;
        server_name  localhost;
        location / {
            root   html;
            index  index.html index.htm index.php;
　　　　　　　 proxy_pass http://localhost:7002;
        }
}

总结：其实就是指定多个server 通过upstream 来进行分配
