apache开启对gzip的支持
修改 httpd.conf 配置
去掉 #LoadModule headers_module modules/mod_headers.so 前面的注释#
去掉 #LoadModule deflate_module modules/mod_deflate.so 前面的注释#
去掉 #LoadModule filter_module modules/mod_filter.so 前面的注释#
然后在底部追加如下配置即可
<ifmodule mod_deflate.c>
DeflateCompressionLevel 6

AddOutputFilterByType DEFLATE text/html
AddOutputFilterByType DEFLATE text/php
AddOutputFilterByType DEFLATE text/xml

</ifmodule>
在.htaccess中的配置
<ifmodule mod_deflate.c>
# 启用对特定MIME类型内容的压缩
SetOutputFilter DEFLATE
# 设置不压缩的文件
SetEnvIfNoCase Request_URI .(?:gif|jpe?g|png|exe|t?gz|zip|bz2|sit|rar|pdf|mov|avi|mp3|mp4|rm)$ no-gzip dont-vary
# 设置压缩的文件
AddOutputFilterByType DEFLATE text/javascript
AddOutputFilterByType DEFLATE text/html
AddOutputFilterByType DEFLATE text/css
AddOutputFilterByType DEFLATE text/plain
AddOutputFilterByType DEFLATE text/xml
AddOutputFilterByType DEFLATE application/json
AddOutputFilterByType DEFLATE application/x-httpd-php
AddOutputFilterByType DEFLATE application/javascript
AddOutputFilterByType DEFLATE application/x-javascript
</ifmodule>配置后会优先使用同名的压缩文件返回到浏览器端，浏览器进行解压，由于文件体积减小了，从而大大提高了对文件的加载速度。
