During the installation of Pikachu vulnerability shooting range, the processing methods of connecting to MySQL database and reporting errors are as follows:

1. Confirm that the database can be connected normally. Try connecting with tools. If it is not normal, please check the configuration problems such as service, user name and password
2. Modify the IP address, user name and password of the database in config.inc.php to the IP, user name and password of the database. Both the root directory and pkxss have this file and need to be modified.

Config.inc.php in the root directory \ pkxss \ Inc also needs to be modified. It’s difficult.
