If you are like me, running only your own projects on a server, you might want to skip authentication
the changes I generally make to the file /etc/redis/redis.conf are
1- At the very beginning, limit the RAM redis can use with the line
maxmemory 2gb
2- Change the supervisor to systemd by modifying the line
supervised no
to
supervised systemd
Now, to test the new config, from the command line, run the following commands
systemctl restart redis-server redis-cli ping config get maxmemory quit
You have just configured redis and tested your new settings.
