现在公网ip资源越来越珍贵，所以多域名监听的应用非常广泛！所谓多域名监听就是用一个端口，比如80或者443，监听多个入口域名！最常见的方法如下：server {
listen 443 ssl;
server_name xxx.xxx.cn;
ssl_certificate ssl/server.pem;
ssl_certificate_key ssl/server.key;
......
}
今天我们来看看小程序开发过程中的常见问题：
1.如何在nginx同一端口同时监听多个域名？
在启用新的域名的时候，只需要另启一个server配置文件，丢在vhosts目录下即可，不会报端口被占，这个维护nginx的大部分人都知道。但是，这里有个地方要注意：不能跨nginx实例。很多同事习惯在同一虚机或者云主机下安装多个nginx实例，如果你在实例1里面用了某个端口，再在实例2里面用这个端口绑不同域名，那对不起了，报错妥妥的出来：
nginx: [emerg] bind() to 0.0.0.0:xxxx failed (98: Address already in use)
nginx: [emerg] still could not bind()
个人建议：不在同一台虚机或者云主机下安装多个nginx实例。
2.http和https如何同时监听？
这种需求还是挺多的，有时候我们的证书需要安装在A10或者F5这类硬负载均衡上，此时，DMZ区的服务器不需要安装证书，只需要监听http端口即可。但与此同时，内网dns直接将A地址指到了服务器，此时又需要在服务器上安装证书。这种场景，就需要服务器同时对http和https端口进行监听，监听https口是为了解析内网https域名，监听http口是为了反向代理从DMZ区过来的http请求。如此，可实现内外网https域名统一。
最常见的配置如下
server {
listen 8080;
listen 443 ssl;
server_name xxx.xxx.cn;;
ssl_certificate ssl/server.pem;
ssl_certificate_key ssl/server.key;
......
}
