找到apache配置文件httpd.conf找到下面两句去掉前面的#，如果没有则添加下面两句话：
LoadModule deflate_module modules/mod_deflate.so
LoadModule headers_module modules/mod_headers.so
然后在httpd.conf的末尾添加
<IfModule deflate_module>
SetOutputFilter DEFLATE
# Don’t compress images and other
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
AddOutputFilterByType DEFLATE text/html text/plain text/xml text/css
AddOutputFilterByType DEFLATE application/x-javascript
</IfModule>
最后重启apache
