Apache增加mod_expires模块+配置指南

为服务器增加文件头缓存控制,合理设置Javascript、图片、Flash文件过期设置,可以有效减少网站文件请求数量,提高网站访问速度。

在Apache中实现缓存控制的模块是mod_expires,对应源文件为mod_expires.c,一般默认安装并没有安装这个模块,我们可以通过以下步骤补充安装之(mod_expires官方说明):

1. Apache的mod_expires模块安装(/usr/local/apache是我的apache安装目录,/root/httpd-2.2.11是apache安装源文件目录):

[php]
/usr/local/apache/bin/apxs -i -a -c /root/httpd-2.2.11/modules/metadata/mod_expires.c[/php]

如果出现类似下面的错误:

[php]
Warning! dlname not found in /usr/local/apache/modules/mod_expires.la.
Assuming installing a .so rather than a libtool archive.
chmod 755 /usr/local/apache/modules/mod_expires.so
chmod: 无法访问‘/usr/local/apache/modules/mod_expires.so’: 没有那个文件或目录
apxs:Error: Command failed with rc=65536[/php]

请按照张宴大师的《为Apache编译添加mod_expires模块出错的解决笔记[原创]》来解决:

[php]gcc -shared -o /usr/local/apache/modules/mod_expires.so /root/httpd-2.2.11/modules/metadata/mod_expires.o
/usr/local/apache/bin/apxs -i -a -c /root/httpd-2.2.11/modules/metadata/mod_expires.c[/php]

2.安装完成后,还需在配置文件httpd.conf文件中增加如下配置:

[php]
ExpiresActive on
ExpiresDefault "access plus 12 month"
ExpiresByType text/html "access plus 12 months"
ExpiresByType image/gif "access plus 12 month"
ExpiresByType image/jpeg "access plus 12 month"
ExpiresByType application/x-javascript "access plus 12 month"
ExpiresByType text/css "access plus 12 month"
ExpiresByType application/x-shockwave-flash "access plus 12 month"
ExpiresByType image/jpg "access plus 12 months"
ExpiresByType image/png "access plus 12 months"
ExpiresByType video/x-flv "access plus 12 months"

[/php]

3. 然后重启Apache即可生效:

[php]/usr/local/apache/bin/apachectl stop
/usr/local/apache/bin/apachectl start[/php]

如果你还想要第2步中没有列出的文件也参与缓存,可以参照以下MIME文件类型对照表增加:
