Log format
vim/usr/local/nginx/conf/nginx.conf//Search Log_format

$remote_addr                客户端IP(公网IP)$http_x_forwarded_for       代理服务器的IP$time_local                 服务器本地时间$host                       访问主机名（域名）$request_uri                访问的url地址$status                     状态码$http_referer               referer$http_user_agent            user_agent

In addition to defining the log format in the Master Profile nginx.conf, you also need to add the virtual host configuration file
Access_log/tmp/1.log Combined_realip;
The combined_realip here is the name of the log format defined in nginx.conf
-T &&-S reload
Curl-x127.0.0.1:80 Test.com-i
Cat/tmp/1.log

Operation Process

[[email protected] ~]# vim /usr/local/nginx/conf/nginx.conf

Format Combined_realip is the log format represented
Log_format combined_realip ' $remote _addr $http _x_forwarded_for [$time _local] '
' $host ' $request _uri "$status"
' "$http _referer" "$http _user_agent";
