How to keep redis server running
And, if you'd like a quick option, run: redis-server --daemonize yes.
The easiest way to launch Redis as a daemon is to edit the configuration file and change the following line:
# 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 yes
Be sure to provide the configuration file on the redis-server command line when you launch it.
An example of configuration file is provided in the Redis distribution.
