cron 작업은 수동으로 실행될 때 작동하지만 crontab에서는 작동하지 않습니다

Question

영원히 node.js를 제어하는 ​​스크립트를 만들었습니다.하지만 수동으로 실행할 때 원하는대로 작동합니다. 크론 작업 @reboot 아무 일도 일어나지 않는다. 나는 cron을 stderr와 stdout을 로그 파일로 리디렉션하도록 설정 했으므로 알아낼 수는 있지만 파일은 절대로 변경되지 않는다.

크론 작업 : 스크립트의 @reboot /sbin/ghost boot &> /home/mary/.ghost.log

Answer 1

일반적인 cron 실수.

모든 경로에 절대 경로를 사용해야합니다. grep, ps, awk 등등도 마찬가지입니다.

Answer 2

시도해 볼 수 있습니다. @reboot /sbin/ghost boot > /home/mary/.ghost.log 2>&1
