apache 同一个IP:端口，绑定多个域名的注意事项

Aapche 如果需要绑定多个域名到一个IP上,是支持的。需要注意以下2点:

1 必须要开启 NameVirtualHost开关选项，

如：NameVirtualHost 220.231.220.231:80

2 NameVirtualHost 需要指定具体的端口

例如":80",跟<VirtualHost 220.231.32.*:80>对应，否则会报错:

mixing * ports and non-* ports with a NameVirtualHost address is not supported, proceeding with undefined results。

翻译过来就是: NameVirtualHost 地址，指定端口和不指定端口混合使用是不支持的，将会产生未逾期的后果。

未逾期的后果就是: 第2个不起作用，仅当一个站点设置起作用。

完整的例子:

#
# VirtualHost example:
# Almost any Apache directive may go into a VirtualHost container.
# The first VirtualHost section is used for requests without a known
# server name.

NameVirtualHost 219.133.61.226:80
