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 <https://linux.die.net/man/1/rsync>`_ installed on the **destination** server
|
|
- SSH access set up between the two servers
|
|
|
|
Non-Docker
|
|
----------
|
|
|
|
On the destination server, run through the :doc:`installation steps<../installation/debian>` with the exception of the following points:
|
|
|
|
- Do not enable the extensions ``unaccent`` and ``citext`` when 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:
|
|
|
|
.. code-block:: shell
|
|
|
|
sudo systemctl stop funkwhale.target
|
|
|
|
On the origin server, create a database backup:
|
|
|
|
.. code-block:: shell
|
|
|
|
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:
|
|
|
|
.. code-block:: shell
|
|
|
|
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:
|
|
|
|
.. code-block:: shell
|
|
|
|
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:
|
|
|
|
.. code-block:: shell
|
|
|
|
sudo systemctl start funkwhale.target
|
|
|
|
Docker
|
|
------
|
|
|
|
On the destination server, run through the :doc:`installation steps<../installation/docker>` 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:
|
|
|
|
.. code-block:: shell
|
|
|
|
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:
|
|
|
|
.. code-block:: shell
|
|
|
|
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:
|
|
|
|
.. code-block:: shell
|
|
|
|
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:
|
|
|
|
.. code-block:: shell
|
|
|
|
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.
