主管不与Gunicorn+Flas合作

Question

我试图在Ubuntu12.04系统中从管理器运行Gunicorn。Gunicorn运行一个Flask应用程序（使用Flask的嵌入式服务器测试简单的RestWeb服务）。我通过关闭GIT repo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，它将只由主管运行。

所以在安装之后，如果我尝试：

cd /usr/local/bin
gunicorn my_app:app -c /path/to/gu_config_file

Gunicorn工作。然后我就杀了它。没有扩展名的便笺配置文件，因为扩展名为“.py”的文件对我不起作用。 所以我编辑主管的配置文件如下：

[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

并更新主管的变更：

supervisorctl reread
# gunicorn: changed
supervisorctl update
# gunicorn: stopped
# gunicorn: updated process group

检测文件中的更改并为Gunicorn程序工作。好吧，但我试着开始：

supervisorctl start gunicorn

变得烦人：

gunicorn: ERROR (abnormal termination)

检查主管日志：

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。。。你能帮助我吗？ 太多了！

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

“我的应用程序”位于/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，例如：

environment=PYTHONPATH=/usr/local/bin:/usr/local/lib/project/

但没用。

编辑2：正如@robertklep在他的评论中所建议的，这是log的输出：

Traceback (most recent call last):

    worker.init_process()

“const”模块位于/usr/local/lib/project中。。。

Answer 1

这不是必要的通行证--Python。如果你使用virtualenv，你把add放在gunicorn的位置。示例：

command=/home/virtualenv/bin/gunicorn application:app -c /home/virtualenv/deploy/gunicorn.conf.py

当Flask代码为时，目录为，例如：

directory=/home/virtualenv/myapp

记住用户是根用户！

user=root

Answer 2

我看不到您在主管配置文件中设置环境：

[program:gunicorn]
environment=PYTHONPATH=/usr/local/bin:/usr/local/lib/project
command=/usr/local/bin/gunicorn my_app:app -c /path/to/.gu_setup
...

如果不起作用，请尝试在调试模式下启动gunicorn：

command=/usr/local/bin/gunicorn --debug --log-level debug my_app:app -c /path/to/.gu_setup

或者直接穿过这条路到gunicorn：

command=/usr/local/bin/gunicorn --pythonpath /usr/local/bin,/usr/local/lib/project my_app:app -c /path/to/.gu_setup

编辑：gunicorn的--pythonpath已损坏，您只能传递一个目录：

command=/usr/local/bin/gunicorn --pythonpath /usr/local/lib/project my_app:app -c /path/to/.gu_setup
