我正在尝试在 Ubuntu 12.04 系统中从 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)。我通过克隆 GIT 存储库安装了 Gunicorn,试图避免“apt-get install”,因为它在安装时运行 Gunicorn 服务器。我不想让它运行,它只会由 Supervisor 运行。
所以安装后,如果我尝试:
cd /usr/local/bin
gunicorn my_app:app -c /path/to/gu_config_file
独角兽的作品。然后我杀了它。注意没有扩展名的配置文件,因为带有“.py”扩展名的我对我不起作用。所以我编辑主管的配置文件,如:
[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
并更新 Supervisor 中的更改:
supervisorctl reread
# gunicorn: changed
supervisorctl update
# gunicorn: stopped
# gunicorn: updated process group
检测文件中的更改并适用于 Gunicorn 程序。好的,但后来我尝试启动它:
supervisorctl start gunicorn
变得烦人:
gunicorn: ERROR (abnormal termination)
检查主管的日志:
2013-03-08 13:07:22,378 INFO spawned: 'gunicorn' with pid 3355
2013-03-08 13:07:22,916 INFO exited: gunicorn (exit status 3; not expected)

2013-03-08 13:07:31,630 INFO gave up: gunicorn entered FATAL state, too many start retries too quickly
我不知道现在该怎么办......你能帮帮我吗?多谢!
编辑:对不起,我忘了说我已将 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。我还编辑了主管配置文件以指示环境变量,例如:
environment=PYTHONPATH=/usr/local/bin:/usr/local/lib/project/
但没有奏效。
编辑2:正如@robertklep 在他的评论中建议的那样,这是日志的输出:
