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 : /etc/systemd/system/redis.service

Answer 1

If you used apt-get when installing

sudo apt-get purge --auto-remove redis-server

If you used makefile when installing

Answer 2

sudo apt-get purge redis

如果不起作用，您可以尝试查找并删除redis文件，主要是redis位于/ usr / bin / redis
