标签：lamp 访问日志 访问日志切割 设置静态文件不记录日志 设置缓存静态文件过期时间
访问日志不记录指定类型的文件在网站大多数元素为静态文件，比如图片、css、js等，这些静态文件都可以不用记录，我们只需要记录哪个ip访问了那个网页就可以；
vim /usr/local/apache2.4/conf/extra/httpd-vhosts.conf在 ErrorLog "logs/111.com-error_log"的下面加入；
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$" img
在CustomLog "logs/111.com-access_log" common 增加env=!img<VirtualHost *:80>
DocumentRoot "/data/wwwroot/111.com"
ServerName 111.com
ServerAlias www.111.com
ErrorLog "logs/111.com-error_log"
SetEnvIf Request_URI ".*\.gif$" 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" common env=!img
</VirtualHost>/usr/local/apache2.4/bin/apachectl -t
/usr/local/apache2.4/bin/apachectl graceful访问111.com/baidu.png会被日志记录下来
curl -x127.0.0.1:80 111.com/baidu.png
tail /usr/local/apache2.4/logs/111.com-access_log
127.0.0.1 - - [05/Mar/2018:16:41:31 +0800] "GET HTTP://111.com/baidu.png HTTP/1.1" 200 7877curl -x127.0.0.1:80 111.com/baidu.png
tail /usr/local/apache2.4/logs/111.com-access_log
127.0.0.1 - - [05/Mar/2018:16:41:31 +0800] "GET HTTP://111.com/baidu.png HTTP/1.1" 200 7877除了生效前被记录下来的一条日志，生效后访问的却并未被记录下来；
日志文件会一直记录着，总有一天会把磁盘空间给占满，一个文件上100G如何查看删除？那么我们可以设置日志按天切割成一个日志文件，一来方便查看日志，而来方便删除老旧日志；
vim /usr/local/apache2.4/conf/extra/httpd-vhosts.conf修改这一条配置CustomLog "logs/111.com-access_log" common env=!img
没有配置过不记录静态文件日志的小伙伴，请忽略掉后面的env=!img
修改成
CustomLog "|/usr/local/apache2.4/bin/rotatelogs -l logs/111.com-access_%Y%m%d.log" common env=!img<VirtualHost *:80>
DocumentRoot "/data/wwwroot/111.com"

[root@shu-test 111.com]#浏览器访问网站图片时，会把静态文件下载到电脑上，这样下次再访问时就不用去远程下载，达到节约服务器带宽的作用；
然而每个网站都是有内容更新的，我们一般设置一天更新一次，不设置更新那么本机访问的网页就是以前的旧网页，而不是更新后的网页；
vim /usr/local/apache2.4/conf/extra/httpd-vhosts.conf增加配置
<IfModule mod_expires.c>
ExpiresActive on //打开该功能的开关
ExpiresByType image/gif "access plus 1 days"
ExpiresByType image/jpeg "access plus 24 hours"
ExpiresByType image/png "access plus 24 hours"
ExpiresByType text/css "now plus 2 hour"
ExpiresByType application/x-javascript "now plus 2 hours"

</VirtualHost>由于增加了内容，调用了新模块expires，那么我们也要让apache加载对应模块才能生效
vim /usr/local/apache2.4/conf/httpd.conf
取消注释
LoadModule expires_module modules/mod_expires.so查询expires模块是否正常加载（加载成功）
/usr/local/apache2.4/bin/apachectl -M |grep expires
expires_module (shared)/usr/local/apache2.4/bin/apachectl -t
/usr/local/apache2.4/bin/apachectl gracefulcurl -x127.0.0.1:80 111.com/baidu.png -I
