<span style="color:#454545;font-family:tahoma, helvetica, arial;font-size:14px;line-height:1;background-color:#FFFFFF;">Nginx的默认虚拟主机在用户通过IP访问，或者通过未设置的域名访问（比如有人把他自己的域名指向了你的ip）的时候生效</span><span style="color:#333333;font-family:-apple-system, BlinkMacSystemFont, " font-size:16px;background-color:#ffffff;"=""></span><br />
<br />
<span style="color:#454545;font-family:tahoma, helvetica, arial;font-size:14px;line-height:1;background-color:#FFFFFF;">最关键的一点是，在server的设置里面添加这一行：</span><span style="color:#333333;font-family:-apple-system, BlinkMacSystemFont, " font-size:16px;background-color:#ffffff;"=""></span><br />
<span style="color:#454545;font-family:tahoma, helvetica, arial;font-size:14px;line-height:1;background-color:#FFFFFF;">listen&nbsp;80&nbsp;default;</span><span style="color:#333333;font-family:-apple-system, BlinkMacSystemFont, " font-size:16px;background-color:#ffffff;"=""></span><br />
<span style="color:#454545;font-family:tahoma, helvetica, arial;font-size:14px;line-height:1;background-color:#FFFFFF;">后面的default参数表示这个是默认虚拟主机。</span><span style="color:#333333;font-family:-apple-system, BlinkMacSystemFont, " font-size:16px;background-color:#ffffff;"=""></span><br />
<br />
<span style="color:#454545;font-family:tahoma, helvetica, arial;font-size:14px;line-height:1;background-color:#FFFFFF;">这个设置非常有用。</span><span style="color:#333333;font-family:-apple-system, BlinkMacSystemFont, " font-size:16px;background-color:#ffffff;"=""></span><br />
<span style="color:#454545;font-family:tahoma, helvetica, arial;font-size:14px;line-height:1;background-color:#FFFFFF;">比如别人通过ip或者未知域名访问你的网站的时候，你希望禁止显示任何有效内容，可以给他返回500.</span><span style="color:#333333;font-family:-apple-system, BlinkMacSystemFont, " font-size:16px;background-color:#ffffff;"=""></span><br />
<span style="color:#454545;font-family:tahoma, helvetica, arial;font-size:14px;line-height:1;background-color:#FFFFFF;">目前国内很多机房都要求网站主关闭空主机头，防止未备案的域名指向过来造成麻烦。就可以这样设置：</span><span style="color:#333333;font-family:-apple-system, BlinkMacSystemFont, " font-size:16px;background-color:#ffffff;"=""></span><br />
<span style="color:#454545;font-family:tahoma, helvetica, arial;font-size:14px;line-height:1;background-color:#FFFFFF;">server&nbsp;{</span><span style="color:#333333;font-family:-apple-system, BlinkMacSystemFont, " font-size:16px;background-color:#ffffff;"=""></span><br />
<span style="color:#454545;font-family:tahoma, helvetica, arial;font-size:14px;line-height:1;background-color:#FFFFFF;">listen&nbsp;80&nbsp;default;</span><span style="color:#333333;font-family:-apple-system, BlinkMacSystemFont, " font-size:16px;background-color:#ffffff;"=""></span><br />
<span style="color:#454545;font-family:tahoma, helvetica, arial;font-size:14px;line-height:1;background-color:#FFFFFF;">return&nbsp;500;</span><span style="color:#333333;font-family:-apple-system, BlinkMacSystemFont, " font-size:16px;background-color:#ffffff;"=""></span><br />
<span style="color:#454545;font-family:tahoma, helvetica, arial;font-size:14px;line-height:1;background-color:#FFFFFF;">}</span><span style="color:#333333;font-family:-apple-system, BlinkMacSystemFont, " font-size:16px;background-color:#ffffff;"=""></span><br />
<br />
<span style="color:#454545;font-family:tahoma, helvetica, arial;font-size:14px;line-height:1;background-color:#FFFFFF;">也可以把这些流量收集起来，导入到自己的网站，只要做以下跳转设置就可以：</span><span style="color:#333333;font-family:-apple-system, BlinkMacSystemFont, " font-size:16px;background-color:#ffffff;"=""></span><br />
<span style="color:#454545;font-family:tahoma, helvetica, arial;font-size:14px;line-height:1;background-color:#FFFFFF;">server&nbsp;{</span><span style="color:#333333;font-family:-apple-system, BlinkMacSystemFont, " font-size:16px;background-color:#ffffff;"=""></span><br />
<span style="color:#454545;font-family:tahoma, helvetica, arial;font-size:14px;line-height:1;background-color:#FFFFFF;">listen&nbsp;80&nbsp;default;</span><span style="color:#333333;font-family:-apple-system, BlinkMacSystemFont, " font-size:16px;background-color:#ffffff;"=""></span><br />
<span style="color:#454545;font-family:tahoma, helvetica, arial;font-size:14px;line-height:1;background-color:#FFFFFF;">rewrite&nbsp;^(.*)&nbsp;http://www.exchangecn.com&nbsp;permanent;</span><span style="color:#333333;font-family:-apple-system, BlinkMacSystemFont, " font-size:16px;background-color:#ffffff;"=""></span><br />
<span style="color:#454545;font-family:tahoma, helvetica, arial;font-size:14px;line-height:1;background-color:#FFFFFF;">}</span><span style="color:#333333;font-family:-apple-system, BlinkMacSystemFont, " font-size:16px;background-color:#ffffff;"=""></span><br />
<span style="color:#454545;font-family:tahoma, helvetica, arial;font-size:14px;line-height:1;background-color:#FFFFFF;">==============================</span><span style="color:#333333;font-family:-apple-system, BlinkMacSystemFont, " font-size:16px;background-color:#ffffff;"=""></span><br />
<br />
<span style="color:#454545;font-family:tahoma, helvetica, arial;font-size:14px;line-height:1;background-color:#FFFFFF;">按照如上设置后，确实不能通过IP访问服务器了，但是在应该用中出现当server_name后跟多个域名时，其中一个域名怎么都无法访问：</span><span style="color:#333333;font-family:-apple-system, BlinkMacSystemFont, " font-size:16px;background-color:#ffffff;"=""></span><br />
<br />
<span style="color:#454545;font-family:tahoma, helvetica, arial;font-size:14px;line-height:1;background-color:#FFFFFF;">设置如下：</span><span style="color:#333333;font-family:-apple-system, BlinkMacSystemFont, " font-size:16px;background-color:#ffffff;"=""></span><br />
