python - スーパーバイザーで Python スクリプトを実行する

Answer 1

This is what I normally do:

• Create a service.conf file which describes the new Python script. This script references the shell script which is the one in reality launching the Python script. This .conf file lives inside /etc/supervisor/conf.d/
• Create a shell script which launches the Python script. Change permissions to executable. chmod 755 service.sh. In this script we actually launch the Python script.
• Configure log_stderr and stderr_logfile to verify issue.
• Update supervisor using reload and then check status:

supervisor> status

alexad RUNNING pid 32657, uptime 0:21:05

service.conf

[program:alexad]
; Set full path to celery program if using virtualenv

command=sh /usr/local/src/gonzo/supervisorctl/alexad.sh
directory=/usr/local/src/gonzo/services/alexa
log_stdout=true             ; if true, log program stdout (default true)
log_stderr=true             ; if true, log program stderr (default false)
stderr_logfile=/usr/local/src/gonzo/log/alexad.err
logfile=/usr/local/src/gonzo/log/alexad.log
autostart=true
autorestart=true
startsecs=10

; Need to wait for currently executing tasks to finish at shutdown.
; Increase this if you have very long running tasks.
stopwaitsecs = 600

; When resorting to send SIGKILL to the program to terminate it
; send SIGKILL to its whole process group instead,
; taking care of its children as well.
killasgroup=true

; Set Celery priority higher than default (999)
priority=500

service.sh

#!/bin/bash
cd /usr/local/src/gonzo/services/alexa
exec python reader.py

問題がデーモン ランナーと同じかどうかはわかりませんが、デーモン コンテキストを直接使用し、supervisord を使用する場合は、context.detach_process を False に設定する必要があります。
