①編輯虛擬主機配置文件/usr/local/apache2.4/conf/extra/httpd-vhosts.conf如下

<VirtualHost?*:80>DocumentRoot?"/data/wwwroot/111.com"ServerName?111.comServerAlias?www.example.com??2111.com.cnErrorLog?"logs/111.com-error_log"CustomLog?"logs/111.com-access_log"?common<IfModule?mod_rewrite.c>RewriteEngine?onRewriteCond?%{HTTP_HOST}?!^111.com$RewriteRule?^/(.*)$?http://111.com/$1?[R=301,L]</IfModule>
</VirtualHost>

說明：

<IfModule mod_rewrite.c> //需要mod_rewrite模塊支持

RewriteEngine on? //打開rewrite功能

RewriteCond %{HTTP_HOST} !^111.com$? //定義rewrite的條件，主機名（域名）111.com滿足條件

RewriteRule ^/(.*)$ http://111.com/$1 [R=301,L] //定義rewrite規則，當滿足上面的條件時，這條規則才會執行。301表示永久重定向的狀態碼，L表示跳轉一次。

②編輯/usr/local/apache2.4/conf/httpd.conf

將LoadModule rewrite_module modules/mod_rewrite.so取消注釋

③重啟服務

④測試
