nginx日志

1.语法:

Syntax:	log_format name [escape=default|json|none] string ...;
Default:	log_format combined "...";
Context:	http    //只能定义在http标签里面,server,location 

2.默认日志格式:

#vim /usr/local/nginx/conf/nginx.conf 
http {
log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
                  '$status $body_bytes_sent "$http_referer" '
                  '"$http_user_agent" "$http_x_forwarded_for"';
access_log logs/access.log main;
error_log logs/error.log;
}
注意:如果定义在server里面只对当前server生效,如果定义在http内server外对所有的server生效

3.nginx日志变量:

$remote_addr				//表示客户端地址
$remote_user				//http客户端请求nginx认证⽤户名
$time_local				//Nginx的时间
$request					//Request请求⾏,GET等⽅法http协议版本
$status					//respoence返回状态码
$body_bytes_sent			//从服务端响应给客户端body信息⼤⼩
$http_referer				//http上⼀级页⾯,防盗链、⽤户⾏为分析
$http_user_agent			//http头部信息,	客户端访问设备
$http_x_forwarded_for		//http请求携带的http信息				  

4.验证:

#nginx -t
#nginx -s reload 
# tail -1  /usr/local/nginx/logs/access.log
