Nginx 记录请求分发日志
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.
http {
log_formatmain
' $remote_user [$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_loglogs/access.logmain;
server{}
...
}
在日志显示的信息为:
