I've succesfully logged in to Wikimedia Tool Labs using SSH and want to explore the WLM-database. I don't have a replica.my.cnf file in my home directory though. it is totally empty.

I found this ticket stating the same problem, pointing to this instruction how to regenerate the replica.my.cnf file. However, I have no such command and probably no <mysql-username> yet.

$ delete-dbuser --config /etc/create-dbusers.yaml maos
-bash: delete-dbuser: command not found

What should I do?
