我正在尝试在Ubuntu 12.04系统中使用Supervisor运行Gunicorn。Gunicorn运行一个Flask应用程序(使用Flask的嵌入式服务器测试的简单REST Web服务)。我已经通过克隆GIT存储库安装了Gunicorn,试图避免使用apt-get install,因为它在安装时运行Gunicorn服务器。我不希望它运行,它将仅由Supervisor运行。
因此,在安装后,如果我尝试:
cd /usr/local/bin
gunicorn my_app:app -c /path/to/gu_config_file
Gunicorn可以正常运行。然后我杀死了它。请注意配置文件没有扩展名,因为对于我来说带有“.py”扩展名的文件无法工作。所以我像这样编辑了Supervisor的配置文件:
[program:gunicorn]
command=/usr/local/bin/gunicorn my_app:app -c /path/to/.gu_setup
directory=/usr/local/bin/
autostart=true
autorestart=true
redirect_stderr=True
并在Supervisor中更新更改:
supervisorctl reread
# gunicorn: changed
supervisorctl update
# gunicorn: stopped
# gunicorn: updated process group
检测文件更改并适用于Gunicorn程序。但是,当我尝试启动它时:
supervisorctl start gunicorn
遇到了烦人的问题:
gunicorn: ERROR (abnormal termination)
检查管理员日志:

我现在不知道该怎么办...你能帮我吗?非常感谢!
编辑:抱歉,我忘记说我已经将PYTHONPATH变量导出为:
export PYTHONPATH=/usr/local/bin:/usr/local/lib/project
'my_app'在/usr/local/bin中。其他模块需要lib路径。我还编辑了Supervisor配置文件,以指示环境变量,如:
environment=PYTHONPATH=/usr/local/bin:/usr/local/lib/project/
但是没有起作用。
编辑2:正如@robertklep在他的评论中建议的那样,这是日志输出:

--pythonpath
可能实际上是有问题的。尝试仅设置--pythonpath /usr/local/lib/project
。 - robertklep--pythonpath /path/to/project
解决了我的问题。谢谢! - Greg Wang
