`ghost install` doesn't create the database

This is Ubuntu with Ghost CLI 5.115.1.

While trying to install my second Ghost instance, it doesn’t create the mysql database. It won’t create it with ghost setup mysql... either. It prints out a message saying,

Setting up "ghost" mysql user [skipped]

I wonder if it skips this and then also skips creating the database?

I find that message odd, because I asked it to use an existing mysql user, ghost-800. But that message mentions ghost.

It will say skipped if there’s nothing to do - can you check your config and confirm if mysql is set up?
