  <p>it looks like I'm having 2 redis services in my machine so how can i remove the first one because it's old and not working when I try to start it, maybe because i tried to delete it long time ago so i think i did it worng so the question is: how i can delete this service : <code>/etc/systemd/system/redis.service</code></p>
