External dependencies

Note

Those dependencies are handled automatically if you are :doc:`deploying using docker <./docker>`

Database setup (PostgreSQL)

Funkwhale requires a PostgreSQL database to work properly. Please refer to the PostgreSQL documentation for installation instructions specific to your os.

On Debian-like systems, you would install the database server like this:

sudo apt-get install postgresql postgresql-contrib

On Arch Linux and its derivatives:

sudo pacman -S postgresql

On Arch, you'll also need to initialize the database. See the Arch Linux wiki.

The remaining steps are heavily inspired from this Digital Ocean guide.

Open a database shell:

sudo -u postgres psql

Create the project database and user:

CREATE DATABASE "funkwhale"
  WITH ENCODING 'utf8';
CREATE USER funkwhale;
GRANT ALL PRIVILEGES ON DATABASE funkwhale TO funkwhale;

Warning

It's important that you use utf-8 encoding for your database, otherwise you'll end up with errors and crashes later on when dealing with music metedata that contains non-ascii chars.

On Debian you will also need to allow the funkwhale unix user to access the database:

cat | sudo tee -a /etc/postgresql/9.5/main/pg_hba.conf << EOF
local   all             funkwhale                               peer
EOF
sudo systemctl restart postgresql

Assuming you already have :ref:`created your funkwhale user <create-funkwhale-user>`, you should now be able to open a postgresql shell:

sudo -u funkwhale -H psql

Unless you give a superuser access to the database user, you should also enable some extensions on your database server, as those are required for Funkwhale to work properly:

sudo -u postgres psql funkwhale -c 'CREATE EXTENSION "unaccent";'

Cache setup (Redis)

Funkwhale also requires a cache server:

• To make the whole system faster, by caching network requests or database queries
• To handle asynchronous tasks such as music import

On Debian-like distributions, a redis package is available, and you can install it:

sudo apt-get install redis-server

On Arch Linux and its derivatives:

sudo pacman -S redis

This should be enough to have your redis server set up.
