HomeBackend DevelopmentPHP TutorialThe setting on nginx prohibits accessing the server through IP and can only be accessed through domain name.

为了避免别人把未备案的域名解析到自己的服务器ip而导致服务器被断网,需要在nginx上设置禁止通过ip访问服务器,只能通过域名访问。
最关键的一点是,在server的设置里面添加这么一行:
Listen 80 default;
后面的default参数表示这个是默认的虚拟主机。
例如:别人如果通过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。具体如下:
Server {
       Listen 80 default;
       Server_name _;
       Return 500;
}
当然,按照上述设置,的确不能让别人通过ip访问服务器了,但是还应该开放一个或多个真实的希望被访问的域名配置,设置如下:
Server {
       Linten 80;
       Server_name www.941db.com; (以世海夺宝网为例)
………..
}

The above introduces the setting on nginx to prohibit access to the server through IP and can only be accessed through domain name, including the content. I hope it will be helpful to friends who are interested in PHP tutorials.

mPDF

mPDF

mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages.
