I'm setting up wordpress following the usertools tutorial but I am not sure what to add for the local host address for the mySql database:
Setting up your MySQL details
We now need to configure the MySQL details, firstly to rename the sample configuration file and then edit it
username@cshell1 username $ cd wordpress
username@cshell1 username $ mv wp-config-sample.php wp-config.php
username@cshell1 username $ nano wp-config.php
Use the cursor keys and change wordpress, username, password, and localhost to your MySQL details. Then press CRTL +X to exit, Y to confirm the changes and then Enter to confirm the filename.
You should have received an email when you activated MySQL which will give you the details you need here including the MySQL server name (either rumpus.plus or humbug) and the username password and database name.
If you don't have the details any more then raise a question via the help assistant and we can reset the details for you.
