node.js - 无法重新启动 redis-server.service : Unit redis-server. 找不到服务

Question

尝试启动 redis-server 但得到:

26195:C 27 Aug 17:05:11.684 # Warning: no config file specified, using the default config. In order to specify a config file use redis-server /path/to/redis.conf

26195:M 27 Aug 17:05:11.684 * Increased maximum number of open files to 10032 (it was originally set to 1024).

26195:M 27 Aug 17:05:11.685 # Creating Server TCP listening socket *:6379: bind: Address already in use

运行 lsof -wni tcp:3000 并杀死本地主机并再次尝试重新启动 redis-server 并得到与上述相同的错误。

尝试过:ps -aux | grep redis(下面的输出)，然后 sudo kill -9 6379

nick4896 12238 0.0 0.1 41432 9048 ? Sl Aug26 0:14 redis-server *:6379

nick4896 26304 0.0 0.0 21300 984 pts/21 S+ 17:08 0:00 grep --color=auto redis

然后运行 ​​sudo service redis-server restart，得到:

Failed to restart redis-server.service: Unit redis-server.service not found.

有什么想法吗？

Answer 1

问题是 redis-server.service 到 redis.service 的符号链接(symbolic link)被删除了。
命令

sudo systemctl enable redis-server

创建符号链接(symbolic link):

Created symlink /etc/systemd/system/redis.service → /lib/systemd/system/redis-server.service.
