多个站点的定义如下

#NameVirtualHost *:80

#
# 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 127.0.0.1:80

<VirtualHost 127.0.0.1:80>
ServerAdmin devgg@devgg.com
DocumentRoot /usr/local/tomcat/webapps/ronglian
ServerName www.ronglian.com
ErrorLog logs/ronglian.com-error_log
CustomLog logs/ronglian.com-access_log common
</VirtualHost>

<VirtualHost 127.0.0.1:80>
ServerAdmin devgg@devgg.com
DocumentRoot /usr/local/wwwroot/chinaface
ServerName www.chinaface.net
ErrorLog logs/chinaface.net-error_log
CustomLog logs/chinaface.net-access_log common
</VirtualHost>

在这里，NameVirtualHost的字段不能省略，否则起apache时报错：

VirtualHost 127.0.0.1.80 overlaps with VirtualHost 127.0.0.1:80, the first has precedence, perhaps you need a NameVirtualHost directive——虽然apache能起，
同错误描述一样，第二个站点的定义被第一个站点的定义所覆盖，即访问第二个站点指向的其实是第一个

NameVirtualHost 字段的端口号不能忽略，否则起apache时报错：
VirtualHost 127.0.0.1:80 — mixing * ports and non-* ports with a NameVirtualHost address is not supported, proceeding with undefined results
[error] VirtualHost 127.0.0.1:80 — mixing * ports and non-* ports with a NameVirtualHost address is not supported, proceeding with undefined results——apache不能起

如果VirtualHost 字段的端口号确实可用，起apache时报错：
VirtualHost 220.231.32.28:0 — mixing * ports and non-* ports with a NameVirtualHost address is not supported, proceeding with undefined results——
但apache可以启动，访问也正常

3 Could not reliably determine the server’s fully qualified domain name

加入ServerName 127.0.0.1即可。
