Nginx自定义日志&获取用户IP和CDN的IP

定义你的nginx配置文件

log_format main '[$time_local] - $HTTP_CLIENT_IP - "$http_referer" '
                '$request $status $body_bytes_sent '
                '"$http_user_agent" "$remote_addr"';
server {
		listen	80;
        ...
		access_log /var/log/nginx/access.log main;
}

格式如下

$时间 $来访IP $域名 $请求 $HTTP状态 $返回字节 $用户agent $回源CDN
