gunicorn.errors.HaltServer:<HaltServer'Worker无法启动.3> django

Question

我有一个django应用程序,并试图先用gunicorn和后来的主管和nginx进行设置.

该应用程序正常运行与正常的django命令 python manage.py runserver

我用pip pip install gunicorn和django版安装了gunicorn1.5.3

当我在虚拟环境中运行下面的命令,如下所示

gunicorn hello.wsgi:application -b xx.xxx.xxx.xx:8000 并面临错误

Traceback (most recent call last):
  File "/root/Envs/proj/bin/gunicorn", line 9, in <module>
    load_entry_point('gunicorn==19.0.0', 'console_scripts', 'gunicorn')()
  File "/root/Envs/proj/local/lib/python2.7/site-packages/gunicorn/app/wsgiapp.py", line 74, in run

    super(Application, self).run()

    Arbiter(self).run()
  File "/root/Envs/proj/local/lib/python2.7/site-packages/gunicorn/arbiter.py", line 169, in run
    self.manage_workers()
  File "/root/Envs/proj/local/lib/python2.7/site-packages/gunicorn/arbiter.py", line 477, in manage_workers
    self.spawn_workers()
  File "/root/Envs/proj/local/lib/python2.7/site-packages/gunicorn/arbiter.py", line 537, in spawn_workers
    time.sleep(0.1 * random.random())
  File "/root/Envs/proj/local/lib/python2.7/site-packages/gunicorn/arbiter.py", line 209, in handle_chld
    self.reap_workers()
  File "/root/Envs/proj/local/lib/python2.7/site-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>

那么为什么实际遇到上述错误并修复了什么？

Answer 1

实际上这里的问题是wsgi文件本身,之前在django 1.3之前,wsgi文件是以扩展名命名的.wsgi,但现在在最近的版本中它将被创建并且扩展名为.pywsgi文件必须是python模块

所以该文件应该hello_wsgi.py和命令一样

gunicorn  hello:application -b xx.xxx.xxx.xx:8000

Answer 2

用--preload运行guncorn可以看到错误日志，像这样

gunicorn app:application --preload -b 0.0.0.0:5000 

这通常会给您更详细的错误消息。

Answer 3

您没有显示完整输出.它可能看起来像

gunicorn.errors.HaltServer: <HaltServer 'Worker failed to boot.' 3>

最后的引用几乎相同,但在您看到所需的信息之前:

ImportError: No module named elcarweb.wsgi

如果您看到此错误,则解决方案是使用--chdir=/your/app/dir参数运行gunicorn .

对于任何面临同样问题的人来说，问题通常出在 django 本身。激活你的 venv 并运行 ./manage.py runserver

这通常会为您提供更详细的错误消息。
