python - gunicorn 不在 supervisord 下工作(但自己工作)

Question

我在监督下运行 gunicorn 没有任何问题，这个周末它停止工作了。

什么时候 application start inside supervisorctl 这是在应用程序日志中:

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>

我正在使用此配置运行应用程序:

[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

如果我在主管之外的终端上运行命令:gunicorn application:application -c gunicorn.conf.py 事情按预期工作。

这是一个 Flask 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，在外部主管时，我运行了:

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 它没有'工作

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，出现了同样的问题，所以我记录了在成为 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--log-file=- 并找出困扰我的错误。
