For example, take phpMyAdmin: after installation, its default access path has a random URL suffix that cannot be modified. This is quite troublesome when you need to map an intranet service to the public network without a public IP address. For instance, when Cloudflare maps an intranet address, it can only use IP + port number, and does not support IP + port number + URL suffix, which makes the application unable to be accessed from the external network.
Currently, this can be done by manually modifying the nginx configuration file at /www/server/vhost/phpmyadmin.conf
Another method is to create a site and configure a reverse proxy; you can choose either option.
