Question

当我运行 sudo systemctl status redis 时，我得到了这个

● redis.service - Redis In-Memory Data Store

当我运行 sudo systemctl status redis-server 时，我得到了这个

● redis-server.service - Advanced key-value store

看起来我的机器上有 2 个 redis 服务，所以我怎么能删除第一个，因为它很旧并且在我尝试启动它时不工作，也许是因为我很久以前就试图删除它，所以我想我做到了，所以问题是:如何删除此服务:/etc/systemd/system/redis.service
