Migrating Forgejo and Gitea

This section describes migrating Forgejo/Gitea data between two Momod servers.

Forgejo (Gitea) has backup and restore documentation. We can move our Forgejo data between Momod servers using that method.

Stop Forgejo

sudo systemctl stop gitea

Switch to user running Forgejo

sudo su -s /bin/bash gitea

Run gitea dump

 cd /tmp
 /usr/local/bin/forgejo dump -c /etc/gitea/gitea.ini
 exit

This should generate a file in /tmp with a name like ‘forgejo-dump-1694445847.zip’. Chown the file to yourself and move it to your home directory ready for download. From your home directory on the server and substituting USER with your own user account name:

sudo mv /tmp/forgejo-dump-1694445847.zip .
sudo chown USER:USER forgejo-dump-1694445847.zip

It is recommended not to trust the database dump in this file and instead generate one with database native tools.

To generate database dump with mariadb tools:

mariadb-dump -u forgejo -p --database forgejo > forgejo-db.sql

Enter the forgejo_db_password variable you have set on the old server.

Copy these two files, the forgejo-dump and forgejo-db, to the new server.

Restoring Forgejo

This very much a manual process of copying data to the correct location and restoring the database dump.

Before starting copy the forgejo-dump and forgejo-db to the new server, then stop Forgejo on that server too.

sudo systemctl stop gitea

Unzip the dump and move the contents to the right locations:

mkdir forgejo-old
unzip -d forgejo-old forgejo-dump-1694445847.zip
cd forgejo-old

sudo mv app.ini /etc/gitea/gitea.ini
sudo rm -rf /var/lib/gitea/data/home /var/lib/gitea/data/jwt /var/lib/gitea/data/queues /var/lib/gitea/data/ssh /var/lib/gitea/data/tmp
sudo mv -f data/* /var/lib/gitea/data/
sudo mv log/* /var/lib/gitea/log/
sudo mv repos/* /var/lib/gitea/repos/
sudo chown -R gitea:gitea /etc/gitea/gitea.ini /var/lib/gitea

Restore the database dump and restart Forgejo

z
mariadb --default-character-set=utf8mb4 -u forgejo -p forgejo < forgejo-db.sql

sudo systemctl start gitea

This will also have copied the gitea.ini file containing the old servers FQDN, if your FQDN has changed you need to rerun the Forgejo role. Either by editing play/dev.yml and running that play or by running the update play:

ansible-playbook --limit NEWSERVER play/update.yml

You should now be able to log into Forgejo - you can check the base url is now set to the correct FQDN in Site Administration section of Forgejo.
