We ended up going with installing the slurm binaries on the VM, and copying the munge key over.

I am getting an error related to the dex service now.

```auto
 failed to initialize storage: failed to perform migrations: creating migration table: unable to open database file: no such file or directory

```

Which I think means that dex either doesn’t know which database to create the migration table in, or I don’t have a valid database installed?

[https://dexidp.io/docs/storage/](https://dexidp.io/docs/storage/)

Looks like I need to install a sql database. I went ahead and installed and configured mysql 8.0

I suppose I need to tell dex what database to use now?

There is a configuration item in /etc/ood/config/ood\_portal.yml

storage\_file: /etc/ood/dex/dex.db

Which doesn’t currently exist. I created the dex db user and database… I think?

```auto
[root@openondemanddev etc]# mysql

But /var/lib/mysql/dex\_db is empty…
