Yes, you are right, thank you. My redis.conf file was broken. As usual, at the end of the day redis error finds you ! Finally setup is done.
My nodebb setup experience = Hey nodebb ! if you want to grow you have to support MySQL. It isn't important how fast redis is because it does not give confidence any time.
