gunicorn 不在 supervisord 下工作（但自己工作）

Question

我运行在主管的指导下使用 gunicorn 没有任何问题，但这个周末它停止工作了。

当在 supervisorctl 中执行 application start 时，这在应用程序日志中：

Traceback (most recent call last):
 File "/usr/local/bin/gunicorn", line 9, in <module>
   load_entry_point('gunicorn==19.0.0', 'console_scripts', 'gunicorn')()
 File "/usr/local/lib/python2.7/dist-packages/gunicorn/app/wsgiapp.py", line 74, in run
   WSGIApplication("%(prog)s [OPTIONS] [APP_MODULE]").run()
 File "/usr/local/lib/python2.7/dist-packages/gunicorn/app/base.py", line 166, in run
   super(Application, self).run()
 File "/usr/local/lib/python2.7/dist-packages/gunicorn/app/base.py", line 71, in run
   Arbiter(self).run()
 File "/usr/local/lib/python2.7/dist-packages/gunicorn/arbiter.py", line 192, in run
   self.halt()
 File "/usr/local/lib/python2.7/dist-packages/gunicorn/arbiter.py", line 292, in halt
   self.stop()
 File "/usr/local/lib/python2.7/dist-packages/gunicorn/arbiter.py", line 343, in stop
   time.sleep(0.1)
 File "/usr/local/lib/python2.7/dist-packages/gunicorn/arbiter.py", line 209, in handle_chld
   self.reap_workers()
 File "/usr/local/lib/python2.7/dist-packages/gunicorn/arbiter.py", line 459, in reap_workers
   raise HaltServer(reason, self.WORKER_BOOT_ERROR)
gunicorn.errors.HaltServer: <HaltServer 'Worker failed to boot.' 3>

我运行正在使用此配置的应用程序：

[program:application]
command=/usr/local/bin/gunicorn application:application -c /home/azureuser/rz-app/gunicorn.conf.py
directory=/home/azureuser/rz-app/
user=root
autostart=true
autorestart=true
redirect_stderr=True
stdout_logfile = /home/azureuser/rz-app/rz-app_log.log
stderr_logfile = /home/azureuser/rz-app/rz-app_errors.log

gunicorn.conf.py的内容如下：

import multiprocessing

bind = "0.0.0.0:5000"

workers = multiprocessing.cpu_count() * 4 + 1
user = 'root'
group = 'root'

max_requests = 200
max_requests_jitter = 20

如果我运行主管外部终端上的命令：gunicorn application:application -c gunicorn.conf.py 事情按预期工作。

这是一个烧瓶应用程序，这里是 application.py 文件：

import sys
reload(sys)
sys.setdefaultencoding("utf-8")

import socket
socket.setdefaulttimeout(12)

from werkzeug.contrib.fixers import ProxyFix

from app import application
application.wsgi_app = ProxyFix(application.wsgi_app)


if __name__ == '__main__':

    application.run(host='0.0.0.0', port=5000, debug=False)

我该如何解决这个问题？

编辑：我注意到这似乎是 root 用户的问题，当在主管之外时，我运行:

sudo /usr/local/bin/gunicorn application:application -c /home/azureuser/rz-app/gunicorn.conf.py，一切正常，但当我这样做时：

sudo su 后跟 /usr/local/bin/gunicorn application:application -c /home/azureuser/rz-app/gunicorn.conf.py 不行

发现问题，它与 gunicorn 或 supervisor 无关，我的应用程序有一个仅在用户中下载的依赖项，我注意到当我在命令之前执行 sudo su 时，同样的问题出现了，所以我记录了作为 root /usr/local/bin/gunicorn --log-file=- application:application -c /home/azureuser/rz-app/gunicorn.conf.py 时发生的事情，添加了 --log-file=- 并发现了困扰我的错误。
