Background
- wampserver 3.1.7, Apache 2.4.37, PHP 7.2.14, MySql 5.7.24, thinkcmf 5.0
Configuration
Search config.inc in the wampserver installation directory and find this php file:
Note that is the one in the phpmyadmin directory. Don’t find it wrong, because there are other files with the same name!
Because the project uses mysql database, so what is changed is this host, user, password. So if the project uses, for example, mariadb, you need to find here to change the corresponding domain, username and password: 
Then restart wampserver, click phpmyadmin and enter the username and password to enter. Now, you can see the remote database you are connected to.
