Configure Nginx

The latest version of nginx configuration consists of four files:

  1. conf.d: User-defined CONF configuration file
  2. sites-available: Configuration file of the default system Settings
  3. sites-enabledBy:sites-availableConfiguration file transformation generated in
  4. nginx.conf: Summarize the contents of the previous three configuration files and set required parameters

When deploying the required Web service, we can copy the default file in site-enabled to conf.d and change the name to **.conf, and then configure it
