Apache 开启压缩传输

在 /etc/httpd/conf/httpd.conf 中添加如下配置：

# Enable gzip - by Jerryhuang  
#  
<IfModule mod_deflate.c>  
    SetOutputFilter DEFLATE  
    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|mov|avi|mp3|mp4|rm)$ no-gzip dont-vary  
   
    AddOutputFilterByType DEFLATE text/*  
    AddOutputFilterByType DEFLATE application/ms* application/vnd* application/postscript application/javascript application/x-javascript  
    AddOutputFilterByType DEFLATE application/x-httpd-php application/x-httpd-fastphp  
    BrowserMatch ^Mozilla/4 gzip-only-text/html  
    BrowserMatch ^Mozilla/4.0[678] no-gzip  
    BrowserMatch MSIE !no-gzip !gzip-only-text/html  
</IfModule>
