apache配置静态缓存
1、打开虚拟主机配置文件vim /usr/local/apache2/conf/extra/httpd-vhosts.conf
2、添加以下模块
在此段CustomLog "|usr/local/apache2/bin/rotatelogs -l /usr/local/apache2/logs/test.com-access_%Y%m%d_log 86400" combined env=!image-request插入以下模块：
<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 "new plus 2 hours"
ExpiresByType application/x-javascript "now plus 2 hours"
ExpiresByType application/x-shockwave-flash "now plus 2 hours"
ExpiresDefault "now plus 0 min"
</IfModule>
3、检查是否成功 /usr/local/apache2/bin/apachectl -t
4、使用curl测试网站logo地址
curl -x127.0.0.1:80 'http://www.test.com/static/image/common/background.png' -I
返回结果如下：
