11.22访问日志不记录静态文件

访问日志不记录指定类型的文件目录概要 网站大多元素为静态文件，如图片、css、js等，这些元素可以不用记录 把虚拟主机配置文件改成如下：

DocumentRoot "/data/wwwroot/www.123.com" ServerName www.123.com ServerAlias 123.com SetEnvIf Request_URI ".*.gif$" img SetEnvIf Request_URI ".*.jpg$" img SetEnvIf Request_URI ".*.png$" img SetEnvIf Request_URI ".*.bmp$" img SetEnvIf Request_URI ".*.swf$" img SetEnvIf Request_URI ".*.js$" img SetEnvIf Request_URI ".*.css$" img CustomLog "logs/123.com-access_log" combined env=!img 重新加载配置文件 -t, graceful mkdir /data/wwwroot/www.123.com/images //创建目录，并在这目录下上传一个图片 curl -x127.0.0.1:80 -I 123.com/images/123.jpg tail /usr/local/apache2.4/logs/123.com-access_log 访问日志不记录指定类型的文件

浏览器可以查看到页面元素，按 F12 查看页面元素内容，它默认定位在Network。如果不是在Network，就去选择下Network，然后刷新下网页，会看到如图

会看到右侧出现很多的元素，每一行都表示一个元素，这些请求，这些访问都会记录到访问日志里面去的，但实际上没有必须记录一些图片、css、js等元素，而这些请求都会记录到日志文件里，就会导致每天的日志访问量很大，对之后的运维很不方便，所以就有了需求，对于静态的元素的uri 不进行记录

排除图片、css、js等，拷贝配置文件到服务器里面

需要拷贝的配置文件

DocumentRoot "/data/wwwroot/www.123.com" ServerName www.123.com ServerAlias 123.com SetEnvIf Request_URI ".*.gif$" img SetEnvIf Request_URI ".*.jpg$" img SetEnvIf Request_URI ".*.png$" img SetEnvIf Request_URI ".*.bmp$" img SetEnvIf Request_URI ".*.swf$" img SetEnvIf Request_URI ".*.js$" img SetEnvIf Request_URI ".*.css$" img CustomLog "logs/123.com-access_log" combined env=!img 打开虚拟主机配置文件 vim /usr/local/apache2.4/conf/extra/httpd-vhosts.conf 未更改前

DocumentRoot "/data/wwwroot/abc.com" ServerName abc.com ServerAlias www.abc.com www.123.com ErrorLog "logs/abc.com-error_log" CustomLog "logs/abc.com-access_log" common DocumentRoot "/data/wwwroot/111.com" ServerName 111.com ServerAlias www.example.com 2111.com.cn # # # AllowOverride AuthConfig # AuthName "111.com user auth" # AuthType Basic # AuthUserFile /data/.htpasswd # require valid-user # # RewriteEngine on RewriteCond %{HTTP_HOST} !^111.com$ RewriteRule ^/(.*)$ http://111.com/$1 [R=301,L] ErrorLog "logs/111.com-error_log" CustomLog "logs/111.com-access_log" combined 更改后的配置文件，在 ErrorLog 下一行插入

[root@hf-01 ~]# vim /usr/local/apache2.4/conf/extra/httpd-vhosts.conf DocumentRoot "/data/wwwroot/abc.com" ServerName abc.com ServerAlias www.abc.com www.123.com ErrorLog "logs/abc.com-error_log" CustomLog "logs/abc.com-access_log" common DocumentRoot "/data/wwwroot/111.com" ServerName 111.com ServerAlias www.example.com 2111.com.cn # # # AllowOverride AuthConfig # AuthName "111.com user auth" # AuthType Basic # AuthUserFile /data/.htpasswd # require valid-user # # RewriteEngine on RewriteCond %{HTTP_HOST} !^111.com$ RewriteRule ^/(.*)$ http://111.com/$1 [R=301,L] ErrorLog "logs/111.com-error_log" SetEnvIf Request_URI ".*.gif$" img SetEnvIf Request_URI ".*.jpg$" img SetEnvIf Request_URI ".*.png$" img SetEnvIf Request_URI ".*.bmp$" img SetEnvIf Request_URI ".*.swf$" img SetEnvIf Request_URI ".*.js$" img SetEnvIf Request_URI ".*.css$" img CustomLog "logs/111.com-access_log" combined env=!img 并保存退出 相当于定义了一个环境 img 是一个标签、一个变量，可以自定义，可以是任意字符 定义”..gif$”、”..jpg$”、”..png$”、”..bmp$”、”..swf$”、”..js$”、”.*.css$”；这些都是 img env=!img 表示 env非 img 类型的都进行日志记录 在设置好配置文件后，先不加载配置文件，先做一个测验

[root@hf-01 ~]# curl -x127.0.0.1:80 111.com/asdasdsaf.jpg -I HTTP/1.1 404 Not Found Date: Thu, 21 Dec 2017 15:35:14 GMT Server: Apache/2.4.29 (Unix) PHP/7.1.6 Content-Type: text/html; charset=iso-8859-1 [root@hf-01 ~]# 在访问这样的请求，不管是404，还是200都会记录日志

查看日志文件，会发现日志文件中没有记录图片的日志，这个就是因为定义了日志标签
