apache配置httpd.conf相关

1.apache开启压缩AddOutputFilterByType

找到并打开apache/conf目录中的httpd.conf文件

在httpd.conf中打开deflate_Module,headers_Module,filter_module模块，具体做法为将 如下两句前面的#去掉：
LoadModule filter_module modules/mod_filter.so
LoadModule deflate_module modules/mod_deflate.so
LoadModule headers_module modules/mod_headers.so

在httpd.conf文件底部加入如下代码配置需要压缩的文件：
<IfModule mod_deflate.c>
SetOutputFilter DEFLATE
AddOutputFilterByType DEFLATE text/plain
AddOutputFilterByType DEFLATE text/html
AddOutputFilterByType DEFLATE text/php
AddOutputFilterByType DEFLATE text/xml
AddOutputFilterByType DEFLATE text/css
AddOutputFilterByType DEFLATE text/javascript
AddOutputFilter DEFLATE js css
AddOutputFilterByType DEFLATE application/xhtml+xml
AddOutputFilterByType DEFLATE application/xml
AddOutputFilterByType DEFLATE application/rss+xml
AddOutputFilterByType DEFLATE application/atom_xml
AddOutputFilterByType DEFLATE application/x-javascript
AddOutputFilterByType DEFLATE application/x-httpd-php
AddOutputFilterByType DEFLATE image/svg+xml
AddOutputFilterByType DEFLATE image/gif image/png image/jpe image/swf image/jpeg image/bmp
# Don’t compress images and other #排除不需要压缩的文件
BrowserMatch ^Mozilla/4 gzip-only-text/html
BrowserMatch ^Mozilla/4.0[678] no-gzip
BrowserMatch MSIE !no-gzip !gzip-only-text/html
SetEnvIfNoCase Request_URI .(?:html|htm)$ no-gzip dont-varySetEnvIfNoCase
#SetEnvIfNoCase Request_URI .(?:gif|jpe?g|png)$ no-gzip dont-vary
SetEnvIfNoCase Request_URI .(?:exe|t?gz|zip|bz2|sit|rar)$ no-gzip dont-vary
SetEnvIfNoCase Request_URI .(?:pdf|doc)$ no-gzip dont-vary
</IfModule>

2.Expires
Expires字段声明了一个网页或URL地址不再被浏览器缓存的时间，一旦超过了这个时间，浏览器都应该联系原始服务器。

#启用expires_module模块
LoadModule expires_module modules/mod_expires.so
# 启用有效期控制
ExpiresActive On
# GIF有效期为1个月
ExpiresByType image/gif A2592000
# HTML文档的有效期是最后修改时刻后的一星期
ExpiresByType text/html M604800
#以下的含义类似
ExpiresByType text/css "now plus 2 months"
ExpiresByType text/js "now plus 2 days"
ExpiresByType image/jpeg "access plus 2 months"
ExpiresByType image/bmp "access plus 2 months"
ExpiresByType image/x-icon "access plus 2 months"
ExpiresByType image/png "access plus 2 months"
