linux - gunicorn ERROR(异常终止)

Question

我正在运行一个 fabric 脚本，除其他外，它应该在 ubuntu 服务器上重启 gunicorn，命令如下:

supervisorctl status projectname:gunicorn | sed "s/.*[pid ]\([0-9]\+\)\,.*/\1/" | xargs kill -HUP

问题是，gunicorn 一开始似乎没有运行，所以无法终止进程，我通过 ssh 进入 amazon ec2 实例并运行

sudo supervisorctl restart projectname:gunicorn' 

我收到一条错误响应:

projectname:gunicorn: ERROR (not running) projectname:gunicorn ERROR (abnormal termination)

所以我尝试通过运行来启动 gunicorn

sudo supervisorctl start projectname:gunicorn

错误是

'projectname:gunicorn: Error (abnormal termination)'

所以我需要 gunicorn 才能运行，但我无法实现这一点

我还检查了 gunicorn 日志和下面的文本，下面是相关输出

2014-01-17 14:58:14 [12260] [INFO] Starting gunicorn 0.14.3

另外，这是配置文件

有什么想法吗？我知道这是很多文字，任何提示或指针将不胜感激

自行运行unicorn，激活虚拟环境并运行

python manage.py run_gunicorn

终端打印出下面的输出

2014-01-19 22:02:35 [14735] [INFO] Starting gunicorn 0.14.3
2014-01-19 22:02:35 [14735] [INFO] Listening at: http://127.0.0.1:8000 (14735)
2014-01-19 22:02:35 [14735] [INFO] Using worker: sync
2014-01-19 22:02:35 [14742] [INFO] Booting worker with pid: 14742

还在虚拟环境中运行运行服务器:

python manage.py runserver 7000
Validating models...

0 errors found
Django version 1.3, using settings 'ce.settings'
Development server is running at http://127.0.0.1:7000/
Quit the server with CONTROL-C.

所以没有明显的错误

编辑 2:

已经和其他几个人谈过这个问题，并被建议查看 gunicorn 日志的权限，它们在这里:

-rw-rw-r-- 1 www-data ubuntu    3270504 2014-01-19 23:23 gunicorn.log

www-data 用户与主管配置中的一组相匹配

编辑 3:我再次运行 gunicorn 命令，但这次添加了日志信息:

gunicorn_django --pythonpath . ce.settings -w 4 --bind             127.0.0.1:9000 --debug --log-level debug

并收到以下错误信息:

所以看起来重要的信息是这样的:

ImportError: Could not import settings 'ce.settings' (Is it on sys.path?): No module named ce.settings

我的设置在设置目录中，并且存在初始化文件，所以问题不在于此。 此外，应用程序在运行服务器上启动，因此设置文件必须是可导入的

(问题由 OP 在问题编辑中回答。转换为社区维基答案。参见 Question with no answers, but issue solved in the comments (or extended in chat))

OP 写道:

Solved the issue (I think)

as per the info in this link https://stackoverflow.com/a/19256794/2049067 , I added the project to the python path

export PYTHONPATH=:/my/path

then ran the gunicorn command again:

gunicorn_django --pythonpath . ce.settings -w 4 --bind             127.0.0.1:9000 --debug --log-level debug

and gunicorn is up and running, and the site is accessible, I exited the ssh and everything is (seemingly) still working. I should also add that before I set the pythonpath I changed the ownerwhip on the gunicorn log:

sudo chown -R www-data:www-data gunicorn.log

Though I dont know if that helped

& seeing how the application has been running for years I dont know how the project was removed from the pythonpath
