Apache的VirtualHost就是在一台机器上实现多个域名（包括二级域名）

配置可以写在/etc/httpd/conf/httpd.conf中，但是建议写在/etc/httpd/conf.d/目录，为每一个站点（域名）写一个配置文件xxx.conf

xxx.conf的格式如下

# file: /etc/http/conf.d/xxx.conf
# vhost: example.com
<VirtualHost *:80>
    ServerAdmin admin@example.com
    ServerName example.com
    ServerAlias www.example.com
    DocumentRoot /var/www/example.com/public_html
    ErrorLog /var/log/httpd/error.log
    CustomLog /var/log/httpd/access.log combined
</VirtualHost>

将上面的example.com改成你的域名即可。

另外，别忘了在/etc/httpd/conf/httpd.conf中开启“NameVirtualHost *:80”这一行，默认是关闭的，否则会出现如下错误：

[warn] _default_ VirtualHost overlap on port 80, the first has precedence

最后：service httpd restart
