Apache 开启Gzip压缩——可压缩js、css等静态文件

编辑httpd.conf文件

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#

第三个模块一定要打开，很多人根据网上的配置无法生效，就是这个模块没有开启。不开启的话下面配置后也无法启动Apache。

然后在最底部添加如下代码

<ifmodule mod_deflate.c>
