The content of this article is about common Nginx logs and setting methods. It has certain reference value. Friends in need can refer to it. I hope it will be helpful to you.
As a programmer, something a little more important than coding is log analysis and query. Common logs and setting methods are listed below.
nginx is divided into two logs: access_log and error_log
The settings need to be in nginx.conf, and the default is passed The source code package compilation and installation nginx directory should be in the
/usr/local/nginx
directory. If you install it through yum or other methods and do not know or do not know the specific nginx installation directory, you can use
find / -name nginx.conf
or
nginx -V | grep prefix ------------- nginx version: nginx/1.13.9 built by gcc 4.8.5 20150623 (Red Hat 4.8.5-16) (GCC) built with OpenSSL 1.0.2k-fips 26 Jan 2017 TLS SNI support enabled configure arguments: --prefix=/usr/local/nginx --with-http_ssl_module
If your source code package is installed by default, open the path as follows
vim /usr/local/nginx/nginx.conf
Find the following content
http { include mime.types; default_type application/octet-stream; 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; ... }
Change log_format Just open the comment of access_log. Log_format can define the log specifications of nginx.
| Name | Annotation |
|---|---|
| $remote_addr | Client/user IP address |
| $time_local | Access time |
| $request | Request method Request address |
| $status | The request status code is consistent with the HTTP status code |
| $body_bytes_sent | The requested address size is calculated in bytes format |
| $http_referer | Request source, from what Local access |
| $http_user_agent | User information (browser information) |
| $http_x_forwarded_for | Forward IP address |
If your source code package is installed by default, open the path as follows
vim /usr/local/nginx/nginx.conf
Find the following content
error_log logs/error.log; #error_log logs/error.log notice; #error_log logs/error.log info;
Just delete the annotation. You can store different error types separately. For example,
error_log logs/error.log notice;
notice is an error type. If you don’t write it, it will be all.
