부팅 시 이 프로세스를 시작할 수 없는 이유는 무엇입니까?

/etc/init.d/puma_a.sh두 개의 스크립트 가 있고 /etc/init.d/puma_b.sh동일한 구성을 가지고 있습니다. 이렇게 두 개의 스타트업을 설정해 보았으나 그 중 하나가 시작 시 로드되지 않습니다. 콘솔에서 수동으로 시작하면 작동합니다. 어떤 아이디어가 있나요?

# Also make sure you `chmod +x pumacontrol.sh`.

# If you need to start puma at boot time run this in debian/ubuntu: update-rc.d pumacontrol.sh defaults
# It will create some links to execute /etc/init.d/pumacontrol.sh start at the begining

# I use this in a system where the rails app is running by a normal user,  where puma is 
# configured in PUMA_CONFIG_FILE. In PUMA_CONFIG_FILE is stated to create a pid file with the PID of 
# puma in the PUMA_PID_FILE file. The socket where nginx is redirecting the web traffic and puma is 
# listening is PUMA_SOCKET

# You need to specify a location for the PUMA_CONFIG_FILE

PUMA_SOCKET=/var/run/site_a.sock

그리고

-rwxr-xr-x 1 root root  4985 Sep 19 19:21 puma_b.sh

고쳐 쓰다:로그를 보면 puma가 시작되지 않는 것을 알 수 있습니다. /etc/init.d/puma_a.sh start수동으로 할 때 작동하기 때문에 이상합니다 .

답변1

먼저 스크립트를 실행 가능하게 만들어야 합니다.

chmod +x puma_a.sh

실행 권한이 없는 스크립트를 시작 시퀀스에 넣는 것은 무시됩니다.
