如何让centos(redhat)配置虚拟主机,让服务器支持多个网站,针对Apache，只需要你修改apache配置文件/etc/httpd/conf/httpd.conf即可。
里面有个example文件，你只要对应配置即可。
#<VirtualHost *:80>
# ServerAdmin webmaster@dummy-host.example.com
# DocumentRoot /www/docs/dummy-host.example.com
# ServerName dummy-host.example.com
# ErrorLog logs/dummy-host.example.com-error_log
# CustomLog logs/dummy-host.example.com-access_log common
#</VirtualHos>
你可以参照我的配置，在httpd.conf最底部添加：
NameVirtualHost *:80
<VirtualHost *:80>
ServerAdmin admin@example.com
DocumentRoot /var/www/html
ServerName www.phpddt.com
#ErrorLog /var/log/httpd/phpddt/error_log
#注意，这里我设置了以天为单位生产日志
ErrorLog "|rotatelogs /var/log/httpd/phpddt/error_log%Y_%m_%d.log 86400 480"
#CustomLog /var/log/httpd/phpddt/access_log common
CustomLog "|rotatelogs /var/log/httpd/phpddt/access_log%Y_%m_%d.log 86400 480" common
</VirtualHost>
<VirtualHost *:80>
ServerAdmin admin@example.com
DocumentRoot /var/www/html/blog
ServerName blog.phpddt.com
ErrorLog /var/log/httpd/blog/error_log
CustomLog /var/log/httpd/blog/access_log common
</VirtualHost>
如上我配置了两台虚拟主机：域名分别为www.phpddt.com blog.phpddt.com
注意，重启apache后才生效(service httpd restart)
