Install and configure Redis on Ubuntu 16.04 with systemd
Raw
install-redis.md
  1. Install pre-requisities

sudo apt-get install build-essential tcl

  1. Install Redis
cd /tmp
curl -O http://download.redis.io/redis-stable.tar.gz
tar xzvf redis-stable.tar.gz
cd redis-stable
make
make test
sudo make install
  1. Configure Redis
sudo mkdir /etc/redis
sudo cp /tmp/redis-stable/redis.conf /etc/redis
sudo nano /etc/redis/redis.conf

In the file, change the supervised directive's value to systemd.

...
supervised systemd
...

Next, specify the working directory for Redis. This is the directory that Redis will use to dump persistent data. We can use /var/lib/redis

...
dir /var/lib/redis
...

Save and close the file.

According to the docs, supervised systemd is intended solely for Type=notify and daemonize yes corresponds to Type=forking.

Alternative settings that seem to be equivalent:

redis.conf redis.service
daemonize no
supervised systemd		 Type=notify
daemonize no
supervised no		 Type=exec
daemonize yes
supervised no		 Type=forking

Example config: Gist.

And need to remember to change the permissions of the config file.
sudo chown redis:redis /etc/redis/redis.conf

I was getting an error when changing the redis configuration using the command redis-cli config rewrite until I changed the ownership of the conf file:

(error) ERR Rewriting config file: Permission denied

In my case, I had in redis.conf

daemonize no
supervised systemd

and in redis.service Type=notify
And starting the redis service with systemd would just hang.
Solution for me was: just get rid of Type=notify
