查看日志格式

[root@dl-001 ~]# vim /usr/local/apache2.4/conf/httpd.conf    //打开主配置文件（搜索 /Log）<IfModule log_config_module>    #    # The following directives define some format nicknames for use with    # a CustomLog directive (see below).    #    LogFormat "%h %l %u %t \"%r\" %>s %b \"%{Referer}i\" \"%{User-Agent}i\"" combined    LogFormat "%h %l %u %t \"%r\" %>s %b" common

说明：combined和common两种格式，默认使用common格式。

common格式的日志

[root@dl-001 ~]# cat /usr/local/apache2.4/logs/111.com-access_log 192.168.36.128 - - [19/Dec/2017:23:16:23 +0800] "GET HTTP://www.example.com/ HTTP/1.1" 200 7192.168.66.128 - - [20/Dec/2017:22:44:18 +0800] "HEAD HTTP://111.com/ HTTP/1.1" 401 -192.168.66.1 - - [20/Dec/2017:22:44:36 +0800] "GET / HTTP/1.1" 401 401192.168.66.1 - dl [20/Dec/2017:22:44:48 +0800] "GET / HTTP/1.1" 500 535192.168.66.1 - - [20/Dec/2017:22:44:57 +0800] "GET / HTTP/1.1" 401 401192.168.66.1 - dl [20/Dec/2017:22:45:22 +0800] "GET / HTTP/1.1" 500 535192.168.66.1 - dl [20/Dec/2017:22:45:25 +0800] "GET / HTTP/1.1" 500 535192.168.66.1 - dl [20/Dec/2017:22:45:32 +0800] "GET / HTTP/1.1" 500 535

更改log的格式为combined

1.修改配置文件

[root@dl-001 ~]# vim /usr/local/apache2.4/conf/extra/httpd-vhosts.conf    ErrorLog "logs/111.com-error_logo"    CustomLog "logs/111.com-access_log" combined    //默认使用common格式改为combined格式

---

2.重新加载

[root@dl-001 wwwroot]# /usr/local/apache2.4/bin/apachectl -tSyntax OK[root@dl-001 wwwroot]# /usr/local/apache2.4/bin/apachectl graceful

---

3.查看日志变化(可以进行一些操作，然后查看log，结果显而易见)

[root@dl-001 ~]# cat /usr/local/apache2.4/logs/111.com-access_log 192.168.66.128 - - [21/Dec/2017:00:21:53 +0800] "HEAD HTTP://www.example.com/ HTTP/1.1" 301 - "-" "curl/7.29.0"192.168.66.128 - - [21/Dec/2017:00:22:11 +0800] "HEAD HTTP://www.example.com/ HTTP/1.1" 301 - "-" "curl/7.29.0"192.168.66.128 - - [21/Dec/2017:00:22:21 +0800] "HEAD HTTP://www.example.com/ HTTP/1.1" 301 - "-" "curl/7.29.0"192.168.66.128 - - [21/Dec/2017:00:22:21 +0800] "HEAD HTTP://www.example.com/ HTTP/1.1" 301 - "-" "curl/7.29.0"192.168.66.128 - - [21/Dec/2017:00:22:22 +0800] "HEAD HTTP://www.example.com/ HTTP/1.1" 301 - "-" "curl/7.29.0"
