nginx基于多端口的虚拟主机

开放80，81端口

firewall-cmd --add-port=80/tcp --permanent
firewall-cmd --add-port=81/tcp --permanent
firewall-cmd --reload

在html下新建文件夹duankou1,duankou2

vim nginx

server {
        listen 81;
        server_name localhost;

        location / {
           root html/duankou1;
           index index.html index.htm;
         }
    }
    server {
        listen       80;
        server_name  localhost;

        location / {
            root   html/duankou2;
            index  index.html index.htm;
