1. 在httpd.conf文件中找到如下配置，将注释去掉

LoadModule deflate_module modules/mod_deflate.so
LoadModule headers_module modules/mod_headers.so

2.在httpd.conf文件最后添加以下配置

<IfModule deflate_module>
   # Insert filter
   SetOutputFilter DEFLATE
   
   # Netscape 4.x has some problems...
   BrowserMatch ^Mozilla/4 gzip-only-text/html
   
   # Netscape 4.06-4.08 have some more problems
   BrowserMatch ^Mozilla/4\.0[678] no-gzip
   
   # MSIE masquerades as Netscape, but it is fine
   # BrowserMatch \bMSIE !no-gzip !gzip-only-text/html
   # NOTE: Due to a bug in mod_setenvif up to Apache 2.0.48
   # the above regex won't work. You can use the following
   # workaround to get the desired effect:
   BrowserMatch \bMSI[E] !no-gzip !gzip-only-text/html
   
   # 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
   
   # Make sure proxies don't deliver the wrong content
   Header append Vary User-Agent env=!dont-vary
</IfModule>

?3.重启服务器，测试
