Nginx日志格式

[sourcecode language="plain"]
[root@tiejiang nginx]# vim conf/nginx.conf #默认的日志格式
#log_format main '$remote_addr - $remote_user [$time_local] "$request" '

'$status $body_bytes_sent "$http_referer" '

'"$http_user_agent" "$http_x_forwarded_for"';

注释
远程IP- 远程用户/用户时间请求方法(如GET/POST) 请求体body长度 referer来源信息 http-user-agent用户代理/蜘蛛 ,被转发的请求的原始IP

192.168.0.102 - - [13/May/2018:20:54:33 +0800] "GET /favicon.ico HTTP/1.1" 404 571 "-" "Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/57.0.2987.98 Safari/537.36 LBBROWSER"
[/sourcecode]

开启z.com的网站访问日志 {#开启zcom的网站访问日志}

[sourcecode language="plain"]
[root@tiejiang nginx]# vim conf/nginx.conf
首先开启注释
log_format main '$remote_addr - $remote_user [$time_local] "$request" '
'$status $body_bytes_sent "$http_referer" '
'"$http_user_agent" "$http_x_forwarded_for"';

然后给网站设置日志的格式
server {
listen 80;
server_name z.com;

location / {
root z.com;
index index.html;
}
access_log logs/z.com.access.log main; #设置z.com的log名称及日志格式
}

[root@tiejiang nginx]# ./sbin/nginx -s reload
[root@tiejiang nginx]# ls logs/ #目录下就有一个z.com.access.log的文件
access.log access.log.20180513 error.log nginx.pid z.com.access.log
[root@tiejiang nginx]# tail -1 logs/z.com.access.log
