Nginx学习笔记10HTTP访问日志

Posted 2020-09-26

(1)access_log是ngx_http_log_module模块的配置项。

 

Syntax: access_log path [format [buffer=size] [gzip[=level]] [flush=time] [if=condition]];

access_log off;

Default:

access_log logs/access.log combined;

Context: http, server, location, if in location, limit_except

 

nginx的access_log和log_format配置项：

log_format用于定义日志格式以及该格式的名称。

http下定义的log_format：

 

log_format  my_access_log $remote_addr,$remote_user,$time_local,$request,$status,$bytes_sent,$http_referer,$http_user_agent;

 

http下定义的access_log，控制在无法匹配其它access_log条件的时候的访问日志：

    access_log logs/http_access.log  my_access_log;

 

 

location下定义的access_log，控制在URL包含/hello/路径时的访问日志：

location ~  ^/hello/ {

             proxy_pass  http://tomcat101.coe2coe.me:8080;

             proxy_set_header X-Real-IP  $remote_addr;

             proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

 

            access_log logs/http_hello_access.log  my_access_log;

 

    }

 

 

通过浏览器访问以下页面：

http://ng.coe2coe.me:8000/hello/

http://ng.coe2coe.me:8000/hello/

http://ng.coe2coe.me:8000/hello/?a=1&b=2&c=3

http://ng.coe2coe.me:8000/abc/?a=1&b=2&c=3

 

产生的http_acess.log：
