实例重新启动时未启动主管 gunicorn 进程

Question

我正在尝试为 Django 配置 gunicorn 和 supervisor。我已经配置了 gunicorn，我可以手动使用 gunicorn 运行 django 应用程序。现在我尝试配置主管，问题是实例重启时没有启动 gunicorn 进程。如果我手动从 supervisorctl 启动应用程序，那么应用程序将开始运行。 当我在 supervisorctl 中看到状态时，它是 FATAL 并且 stderr 说

似乎 config 包不适用于 gunicorn。尝试将项目目录显式添加到pythonpath，如下所示：

/subscription/app/supervisor/conf.d/subscriptionapp.conf

[program:subscriptionapp]

command=/subscription/app/subscriptionapp/venvs/subscriptionapp/bin/gunicorn -c /subscription/app/subscriptionapp/subscriptionapp_gunicorn.py --pythonpath '/subscription/app/subscriptionapp/subscription-project,/subscription/app/subscriptionapp/venvs/subscriptionapp/lib/python3.4/site-packages/' config.wsgi

user=www-data
directory=/subscription/app/subscriptionapp/subscription-project

environment=PORT=8000,ADDRESS=127.0.0.1,LANG=en_US.UTF-8,DJANGO_SETTINGS_MODULE=config.settings.base,PATH="/subscription/app/subscriptionapp/venvs/subscriptionapp/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin"

stdout_logfile=/subscription/var/log/supervisor/subscriptionapp-stdout.log
stderr_logfile=/subscription/var/log/supervisor/subscriptionapp-stderr.log
killasgroup=true
stopasgroup=true

如果这有助于 gunicorn “找到”config，则可能是您的 gunicorn configuration file 未正确加载。根据您的 gunicorn 版本，从 python 模块加载设置可能需要特殊形式，如文档中所示：

在 19.4 版更改：从 Python 模块加载配置需要 python: 前缀。
