Example of how to set up a third-level domain name in nginx

Problem Description

By configuring nginx, you can set up an IP address to access different web applications through different ports, but after a long time, the relationship between the port number and the application becomes vague.

For example, http://120.79.79.XX:9001 and foreign.XXX.xin. Although these two URLs point to the same website, the latter is obviously more literal and much better than the former. At the same time, in website SEO, the latter has a higher weight than the former.

Basics

Top-level domains: .com .cn

Second-level domain name: baidu.com sina.com, where baidu and sina are second-level domain names

Third-level domain name: zhidao.baidu.com, zhidao is the third-level domain name

Basic steps

• Setting up geocoding
• Configure nginx listening
• Configure nginx redirect

Create a geocode

The author uses Alibaba Cloud. After logging into the Alibaba Cloud backend, add an A record and fill in the third-level domain name into the host record. For specific filling methods, please refer to the figure below

Configure nginx

Modify the default file in /etc/nginx/sites-aviablable. The complete code is as follows:

server {
  listen 80 default_server;
  listen [::]:80 default_server;
  root /var/www/html/wordpress;
  index index.php index.html index.htm index.nginx-debian.html;

  server_name www.xXXX.xin;

  location / {
    try_files $uri $uri/ =404;
  }
  location ~ \.php$ {
    include snippets/fastcgi-php.conf;
    fastcgi_pass unix:/run/php/php7.0-fpm.sock;
  }
  location ~ /\.ht {
    deny all;
  }
}
#Serve 2
server {
  listen 80;
  server_name foreign.XXX.xin;
  location / {
    proxy_pass http://120.79.XX.XX:9000/;
  }
}

Both services listen to the same port 80, but the server_name of service 2 remains consistent with the newly set address resolution. Then set proxy_pass to forward the information obtained from port 80 to port 9000.
