Advanced users can connect to a MySQL database using the "mysql" command line tool.
This is only recommended for advanced users who are familiar with SQL; most users will probably prefer phpMyAdmin, which provides a graphical MySQL interface.
To use the "mysql" tool, you'll first need to connect to the shell using telnet or SSH. When connected, type the following command, replacing "database_name" in both places with the actual name of the MySQL database you want to use:
mysql -u database_name -p database_name
You will be asked to enter a password. This is the password you chose when you created the MySQL database, not your account password.
