How do I log into a brand new install?


I just finished following the Install Mattermost Omnibus — Mattermost documentation and I have a shiny new Mattermost install. Kudos for making this process so easy!

However, I’m feeling a little like a chump because I can’t figure out how to log into my instance. When navigating to my install’s URL, I’m prompted to log in, but I’m not sure what the default username / password is and I was never prompted to create an account during install.

When clicking the “Don’t have an account?”, it prompts me to contact my workspace admin. However, I’m not sure how to log in as the admin account.

Where did I go wrong?

I found New Docker install, unable to create first Mattermost System Admin user and attempted to use the recommended command:

mmctl --local user create --email --username yourusername --password yourpassword --system-admin

However, when attempting to run that, I’m getting the following error:

Error: Unable to create user. Error: : <untranslated>, failed to get Group with name=XXX: dial tcp [::1]:5432: connect: connection refused

I figured it out :slight_smile:

I had already installed Postgresql 15 and when Omnibus installed Postgresql 13 it confused things. I ended up fully removing Postgresql 15 and now things are working properly :tada:

Hi @LinuxLefty, welcome to the Mattermost forums and sorry for the late reply!

Glad to hear you figured it out on your own - should the documentation make the fact that PostgreSQL is installed alongside the application server more prominent or what would have helped you to not run into this issue?
