本文是在类unix系统(freebsd)下通过Apache服务器来实现的，若你的web服务器不是apache，本文可能不适用。
Apache服务器下可以利用.htaccess文件启动Gzip网页压缩，这方法是通过阿帕契(Apache)的Enabling Compression来达到。请通过FTP将您的.htaccess文件下载回来，如果没有请用记事本建立一个，储存时类型请选择所有文档，然后档名输 入.htaccess即可。在.htaccess文件中请加入以下语法，然后保存上传覆盖即可。
# BEGIN WordPress

RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ – [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>
# END WordPress
