To use Redis with the presented configuration, client programs need to access Redis’s socket at /var/run/redis/redis-server.sock. You need to add the running client users to the redis group. As an alternative you can also use socat to create a copy of the socket with the appropriate permissions.


In this example we will use /redis as the database destination to avoid filling up the root partition.
