10-2 11 静态不记录 日志切割 静态过时时间

11.22 访问日志不记录静态文件

• 网站大多元素为静态文件，如图片、css、js等，这些元素能够不用记录

把虚拟主机配置文件改为以下：

conf/extra/http-v
...
<VirtualHost *:80>
	DocumentRoot "/data/wwwroot/ddd.com"
	ServerName ddd.com
	ServerAlias ttt.com eee.com www.example.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/ddd.com-access_log" combined env=!img
</VirtualHost>
...
 bin/apachectl -t/graceful
 cd /data/wwwroot/ddd.com/  //在这目录下上传一个图片

[root@axiang-02 apache2.4]# curl  -x127.0.0.1:80 -I ddd.com/aming.png

能够看到，没有访问png的记录

11.23 访问日志切割

CustomLog "|/usr/local/apache2.4/bin/rotatelogs -l logs/ddd.com-access_%Y%m%d.log 86400" combined env=!img

11.24 静态元素过时时间

• 浏览器访问网站的图片时会把静态的文件缓存在本地电脑里，这样下次再访问时就不用去远程下载了

apache能够设置缓存保存时间

cd /usr/local/apache2.4/ 
vim conf/extra/httpd-vhosts.conf
...
<IfModule mod_expires.c>
ExpiresActive on 
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"
ExpiresByType application/javascript "now plus 2 hours"
ExpiresByType application/x-shockwave-flash "now plus 2 hours"
ExpiresDefault "now plus 0 min"
</IfModule>
...
vim conf/httpd.conf 
	/expires_module //开启
bin/apachectl -M | grep expire 
bin/apachectl -t 
bin/apachectl graceful 
curl -x127.0.0.1:80 ddd.com/aming.png -I

如图，cache-control: max-age为缓存有效期
