apache实现动态子域名，abc.zblog.com，则访问/data/www/default/zblog/abc

1.查找httpd.conf所在的位置

root@instance-baidu:/usr/local/apache/conf# sudo find / -name httpd.conf/usr/local/apache/conf/httpd.conf

2.修改httpd.conf

vi /usr/local/apache/conf/httpd.conf
#取消注释这行
LoadModule rewrite_module modules/mod_rewrite.so

3.修改虚拟主机的配置(如何配置虚拟主机）

sudo vi /usr/local/apache/conf/vhost/default.conf

<VirtualHost *:80>DocumentRoot /data/www/default/zblog ServerName zblog.com Rewriteengine On RewriteCond %{HTTP_HOST} ^[^.]+\.zblog\.com$ RewriteRule ^(.+) %{HTTP_HOST}$1 [C] RewriteRule ^([^.]+)\.zblog\.com(.*) /$1$2 SetOutputFilter DEFLATE Options FollowSymLinks DirectoryIndex index.php index.html index.htm</VirtualHost>

重启一下服务　service httpd restart

4.修改hosts文件做测试：

IP改为你自己的服务器IP

sudo vi /etc/hosts127.111.39.58 abc.zblog.com127.111.39.58 zblog.com127.111.39.58 uuu.com

 abc文件夹的内容是：

root@instance-baidu:/data/www/default/zblog/abc# pwd/data/www/default/zblog/abcroot@instance-baidu:/data/www/default/zblog/abc# cat index.html i am abc page.
