I have been playing around with RunCloud.io with Google Cloud VM/VPS. While the installation creates a default username/password for accessing the DB; for some reason, on my server, the password was not the same as what showed up at end of the installation.
I do not know why this happened. Perhaps re-install process was the culprit. Anyhow, I was not able to create a Database or User. I would enter the information but upon refresh, no Database was present. When I checked in the Error logs however, the error that came up was:
Your database is offline. Please start your database to add new database.
This was solved by fixing the password as per instructions of RunCloud.io when you go to add a Database:
If you have changed your root database password, please insert your new password in /etc/mysql/my.cnf or adding new database won't work.
Just SSH as root to your server and add the correct password for MySQL root in the config file
