Migrating GitLab from one server to another (with external postgres)
So I have a gitlab server, it’s running on https://git.volkor.me/ I use it for my personal projects, along with learning how to properly setup environments and such.
- Ensure the old server is up to date.
sudo apt update && sudo apt dist-upgrade
- Create a backup
sudo gitlab-rake gitlab:backup:create
- copy this backup to the new server
scp /var/opt/gitlab/backups/XXXXXXXXX_gitlab_backup.tar NEW_SERVER_IP:~
- Actually Install gitlab on the new server now
- Create the user and database in postgres, with the same user/pass and such (READ NODE AT THE BOTTOM)
- ensure you’ve copied the gitlab.rb and gitlab-secrets.json too!
- stop unicorn and sidekiq
gitlab-ctl stop unicorn && gitlab-ctl stop sidekiq
- move the backup to the correct directory (default: /var/opt/gitlab/backups)
- run the restore command:
gitlab-rake gitlab:backup:restore BACKUP=XXXXXXXXX
- start gitlab again, and check everything.
gitlab-ctl start && gitlab-rake gitlab:check SANITIZE=true
Note at the bottom
Due to this bug/error you must temporarily give superuser permissions to postgres user (git) do this for the first reconfigure then.
sudo -u postgres psql
alter role git superuser;
alter role git nosuperuser;
You’re done now, you can close this page (or look at my other stuff I guess)
