- 나는 사용하고있다이 스크립트내 스크립트를 서비스로 실행하려면
- 저는 Linux Mint 17.3 Rosa를 사용하고 있습니다.

시작/중지가 작동할 때도 있고 작동하지 않을 때도 있습니다. 때로는 서비스 중지 명령이 수행되지 않기 때문에 수동으로 프로세스를 종료해야 합니다.
이 스크립트는 이 daemon도구를 사용합니다.

1. 시작-중지-데몬을 사용하세요대안으로 나는 사용해 보았습니다.이것사용은 되지만 start-stop-daemon전혀 실행되지 않습니다.
daemon스크립트
이를 시도하고 디버깅하기 위해 daemon명령에서 디버깅을 활성화했습니다. 그런 다음 서비스를 시작하고 중지하려고 합니다.
서비스를 시작할 때:
Starting TEST...daemon: debug: handle_stdout_option(spec = daemon.info)
daemon: debug: store_syslog(spec = daemon.info)
daemon: debug: handle_stderr_option(spec = daemon.err)
daemon: debug: store_syslog(spec = daemon.err)
daemon: debug: config()
daemon: debug: config_load(configfile = /etc/daemon.conf)
daemon: debug: config_load(configfile = /root/.daemonrc)
daemon: debug: config_process(target = *)
daemon: debug: config_process(target = TEST)
daemon: debug: handle_name_option(spec = TEST)
daemon: debug: handle_pidfiles_option(spec = /var/run)
daemon: debug: handle_stdout_option(spec = daemon.info)
daemon: debug: store_syslog(spec = daemon.info)
daemon: debug: handle_stderr_option(spec = daemon.err)
daemon: debug: store_syslog(spec = daemon.err)
daemon: debug: sanity_check()
daemon: debug: preventing core files

그리고 서비스가 시작되었습니다.

그러나 서비스는 결코 멈추지 않습니다.
시도해 도 항상 멈추지는 않습니다 sudo kill -9 PID(때때로 사용이 중지되지만 항상 그런 것은 아닙니다).
내 디버깅 프로세스
나는 다음과 같은 서비스를 실행하고 있습니다 :
sudo /etc/init.d/test start
ps그런 다음 and 를 사용하여 관찰합니다 lsof.
$ ps aux |grep TEST

질문
제가 주목한 한 가지는 위의 정보에서 볼 수 있지만 /run/TEST.pid여기에도 표시된다는 것입니다.
/var/run/TEST.pid
데몬 스크립트는 이 /var/run디렉터리만 사용합니다. 이런 일이 일어나야 할지 잘 모르겠습니다.
