 upstream servers {  
        ip_hash; #hash，ip轮训
        server localhost:8400;   
               
  }  
 
server {  
        listen       80;  
        server_name  localhost;   #这里可以配置多个ip
  
        #charset koi8-r;  
  
        #access_log  logs/access.log  main;  
      
        location / {  
         proxy_set_header   Host             $host;  
         proxy_set_header   X-Real-IP        $remote_addr;  
         proxy_set_header   X-Forwarded-For  $proxy_add_x_forwarded_for;  
         proxy_pass http://servers;  
         proxy_redirect off;  
        }  
        error_page   500 502 503 504  /50x.html;
        location = /50x.html {
            root   html;
        }
}
