Suggested Redis socket configuration not working

[melissaboiko]

Current install docs say:

If you are using a Unix socket for Redis, then:

• Set REDIS_HOST to the path of the socket, e.g. /run/redis/redis.sock
• Set REDIS_PORT to null

What worked for me was rather:

REDIS_SCHEME=unix
REDIS_PATH=/run/redis/redis-server.sock
# REDIS_HOST=
# REDIS_PORT=
# REDIS_PASSWORD=
