apache多域名配置

要求:2个域名，对应1个ip，也就是一个服务器下2个目录。

跟着网上的教程找到conf.httpd

<VirtualHost 101.xxx.xxx.xxx:80>

    DocumentRoot /var/www/html/A

    ServerName www.A.com

   <Directory "/var/www/html/A">

        Options Indexes FollowSymLinks

        AllowOverride None

        Order allow,deny

        Allow from all

   </Directory>

</VirtualHost>

<VirtualHost 101.xxx.xxx.xxx:80>

    DocumentRoot /var/www/html/B

    ServerName www.B.com

   <Directory "/var/www/html/B">

        Options Indexes FollowSymLinks

        AllowOverride None

        Order allow,deny

        Allow from all

   </Directory>

</VirtualHost>

打开 NameVirtualHost 的注释，修改如下：
NameVirtualHost 101.xxx.xxx.xxx:80

然后启动httpd的时候  一直警告,
httpd: Could not reliably determine the server's fully qualified domain name, using localhost.localdomain for ServerName

解决如下:

hostname -f 查看 hostname.

然后在httpd.conf最后一行添加

ServerName 你的hostname

我是这样的:

ServerName  localhost:80

重启后， 两个域名分别能访问到不同的目录下

或者: (未验证)

查看 /etc/hosts

显示如下:

127.0.0.1    localhost.localdomain localhost host.server4-245.com

::1          localhost.localdomain localhost host.server4-245.com

那么在 httpd.conf 中添加:

ServerName host.server4-245.com
