服务器ip地址被陌生域名解析了，导致输入别人的域名也能打开自己的网站。原因是把ip地址访问权限删除，只允许服务器上指定的域名来访问，此时需要修改apache服务器的vhost.conf文件
<VirtualHost *:80>
ServerAdmin webmaster@dummy-host.example.com
DocumentRoot "D:\wwwroot\emptyError" //这里将所有的非指定域名指向到此空目录去
ServerName *
ErrorLog "logs/www.tongrentangsxls.com-error.log"
CustomLog "logs/www.tongrentangsxls.com-access.log" common
</VirtualHost>
<VirtualHost *:80>
ServerAdmin webmaster@dummy-host.example.com
DocumentRoot "D:/wwwroot/xxx.com"
ServerName xx.com
ErrorLog "logs/www.tongrentangsxls.com-error.log"
CustomLog "logs/www.tongrentangsxls.com-access.log" common
</VirtualHost>
