What is the role of basedir in mysql?

In MySQL, the basedir parameter specifies the path to the root directory of the MySQL installation. This parameter is typically used to specify the installation directory of the MySQL server so that MySQL can correctly locate its installation files and configuration files. When the MySQL service starts, it first determines the installation path of MySQL based on the basedir parameter, and then loads other related configuration files. Therefore, the basedir parameter plays a very important role in the running process of MySQL.
