启动失败，出现问题

  Job for redis-server.service failed because the control process exited with error code.
See "systemctl status redis-server.service" and "journalctl -xe" for details.

解决：修改redis.service,将User=redis修改成User=root 
###用户名

  vim /usr/lib/systemd/system/redis.service
5，保存关闭后，启动redis.service

  systemctl start redis

6，启动失败，出现问题

  Warning: ***.service changed on disk. Run 'systemctl daemon-reload' to reload units.

解决：执行systemctl daemon-reload

7，启动redis.service

  systemctl start redis

8，查看redis是否启动成功？

  ps -ef |grep redis

9，若启动成功，将redis.service设置为开机启动

  systemctl enable redis

10，查看开机启动服务中是否有redis.service

  systemctl list-unit-files |grep enabled

11，重启系统后，查看redis是否启动成功？

  ps -ef |grep redis
