Migrating to a New Server
Sometimes, it may be necessary or desirable to migrate your existing Funkwhale setup to a new server. This can be helpful if you need to boost resources or if you wish to use a different hosting platform.
In this guide, the existing Funkwhale setup is called the origin server, and the new setup the destination server.
Requirements
To get started with your new setup, you will need to have the following:
rsync installed on the destination server
SSH access set up between the two servers
Non-Docker
On the destination server, run through the installation steps with the exception of the following points:
Do not enable the extensions
unaccentandcitextwhen setting up the database;Do not initialize the database by applying the migrate command;
Do not create an admin account.
Stop all funkwhale related services on the destination server:
sudo systemctl stop funkwhale.target
On the origin server, create a database backup:
sudo -u funkwhale pg_dump -d funkwhale > "db.dump"
On the destination server, use rsync to fetch the contents of /srv/funwkhale/data/media/music/ and /srv/funkwhale/data/media/ from the origin server, as well as the database dump and the .env file:
origin = <origin server IP/hostname>
username = <your username>
rsync -a $username@$origin:/srv/funkwhale/data/media/ /srv/funkwhale/data/media/
rsync -a $username@$origin:/srv/funkwhale/data/music/ /srv/funkwhale/data/music/
rsync -a $username@$origin:/srv/funkwhale/config/.env /srv/funkwhale/config/
rsync -a $username@$origin:/srv/funkwhale/db.dump /srv/funkwhale/
On the destination server, restore the database dump:
sudo psql -d funkwhale db.dump
Once the database has been restored, follow the database migration steps from the non-docker installation guide to complete the installation on the destination server.
Ensure that all DNS changes have been made and start the services:
sudo systemctl start funkwhale.target
Docker
On the destination server, run through the installation steps but skip the docker-compose run --rm api python manage.py migrate step.
Stop all funkwhale related containers on the destination server.
On the origin server, create a database backup:
docker exec -t funkwhale_postgres_1 pg_dumpall -c -U postgres > "db.dump"
On the destination server, use rsync to fetch the contents of /srv/funwkhale/data/media/music and /srv/funkwhale/data/media from the origin server, as well as the database dump nd the .env file:
origin = <origin server IP/hostname>
username = <your username>
rsync -a $username@$origin:/srv/funkwhale/data/media/ /srv/funkwhale/data/media/
rsync -a $username@$origin:/srv/funkwhale/data/music/ /srv/funkwhale/data/music/
rsync -a $username@$origin:/srv/funkwhale/.env /srv/funkwhale/
rsync -a $username@$origin:/srv/funkwhale/db.dump /srv/funkwhale/
Initialize the Postgres container with the funkwhale database and its user. For easier, we create a db init dump file than we import in the postgres container:
echo "CREATE DATABASE "funkwhale"
WITH ENCODING 'utf8';
CREATE USER funkwhale;
GRANT ALL PRIVILEGES ON DATABASE funkwhale TO funkwhale;" > init.dump
docker exec -i funkwhale_postgres_1 psql -U postgres -d postgres < "init.dump"
After that, we can restore the database dump:
docker exec -i funkwhale_postgres_1 psql -U postgres -d postgres < "db.dump"
Once the database has been restored, run the migrations following the docker installation guide.
Ensure that all DNS changes have been made and start the services.
