Enable Redis to Start at Boot If all of your tests worked, and you would like to start Redis automatically when your server boots, you can enable the systemd service. To do so, type: sudo systemctl enable redis.
You can obtain a list of all the supported configuration parameters by typing CONFIG GET * in an open redis-cli prompt. All the supported parameters have the same meaning of the equivalent configuration parameter used in the redis.
When using Supervisord to manage server programs like databases that often spawn or daemonize, look for a flag in the startup command or in the config file. There is an exception with databases like MySQL where recommended practice is to use a proxy to start mysqld_safe and let it manage the sub processes.
In redis.conf for newer versions (i.e. 3.x) the default is to disable daemon but it may have been edited by your package. Also be sure you didn't install with an upstart script that will respawn.
# By default Redis does not run as a daemon. Use 'yes' if you need it.
# Note that Redis will write a pid file in /var/run/redis.pid when daemonized.
daemonize no
