<VirtualHost *:80>
    DocumentRoot "/data/wwwroot/111.com"
    ServerName 111.com
    ServerAlias www.example.com  2111.com.cn

    <IfModule mod_rewrite.c>
        RewriteEngine on
        RewriteCond %{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取消註釋

③重啟服務

④測試

[root@test_01 ~]# curl -x192.168.231.128:80 2111.com.cn -I
