Nginx 记录请求分发日志设置

在nginx接收到请求之后, 需把请求分发到后端WEB服务集群.

在这里需要记录分发日志, 来分析后端每台WEB服务器处理的请求数目.

<pre name="code" class="python">http {
log_format  main  
  ' $remote_user [$time_local]  $http_x_Forwarded_for $remote_addr  $request '
 '$http_x_forwarded_for '                     
 '$upstream_addr '                      
 'ups_resp_time: $upstream_response_time '                      
 'request_time: $request_time';

access_log  logs/access.log  main;

server{}
...
}

 在日志显示的信息为:
