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
2- Change the supervisor to systemd by modifying the line
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.
