에 대해 위의 스크립트를 작성했습니다 init.d. 로 이식하고 싶습니다 systemd.

직접 작성해서 저장해봤는데 /etc/systemd/system/redis.service변수가 확장되지 않네요

그럼 내가 그랬어

sudo chmod 777 /etc/systemd/system/redis.service
sudo chmod 777 /etc/systemd/system/redisenv
sudo systemctl daemon-reload
sudo systemctl start redis-service

하지만 그것은 돌아온다

Failed to start redis.service: Unit redis.service is not loaded properly: Invalid argument. 
See system logs and 'systemctl status redis.service' for details.

그리고 sudo systemctl status redis.service돌아오다

스크립트를 init.d이식하는 데 도움이 되었나요 systemd?

제가 본 첫 번째 문제는 변수가 변수가 아니고 스크립트의 확장이 일어나지 않는다는 것입니다
