gunicorn.errors.HaltServer：<HaltServer'Worker无法启动。 3> django
我有一个Django的应用程序，并试图设置它与gunicorn第一，后来与主pipe和nginx。
该应用程序正常运行与正常的Django命令完全像python manage.py runserver
我安装gunicorn使用pip像pip install gunicorn和django版本是1.5.3
当我在下面的虚拟env中运行下面的命令
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 WSGIApplication("%(prog)s [OPTIONS] [APP_MODULE]").run() File "/root/Envs/proj/local/lib/python2.7/site-packages/gunicorn/app/base.py", line 166, in run super(Application, self).run() File "/root/Envs/proj/local/lib/python2.7/site-packages/gunicorn/app/base.py", line 71, in 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，为什么实际上遇到了上述错误，最新的解决scheme呢？
其实这里的问题是wsgi文件本身，之前在django 1.3之前的wsgi文件被命名为.wsgi的扩展名，但是现在在最近的版本中将会创build并扩展.py ，即wsgi文件必须是python模块
所以文件应该是hello_wsgi.py ，命令应该是
gunicorn hello:application -b xx.xxx.xxx.xx:8000
你没有显示完整的输出。 这可能看起来像

最后一次引用几乎相同，但在您看到所需的信息之前：
ImportError: No module named elcarweb.wsgi
如果你看到这个错误，那么解决方法是用--chdir=/your/app/dir参数运行gunicorn。
我得到了同样的错误。 Gunicorn以root身份执行时正在工作，但以非特权用户身份执行时以此方式失败。 在我的情况下，我安装了'数据集'python模块'pip安装数据集'，它拧上/usr/lib/python2.7/site-packages/dataset的权限只能由root帐户读取。 在其他模块安装为依赖像这是正常的。
修正：
chmod -R a+rX /usr/lib/python2.7/site-packages/dataset* chmod -R a+rX /usr/lib/python2.7/site-packages/normality*
还有一个问题是用pip自动安装的yaml包，但是我还没有find什么。 解决的办法是从fedora软件包重新安装：
dnf -y install python-yaml
我也有类似的错误在Ubuntu 16.04，Django 1.11，使用systemd。
我的问题是，我已经把我的设置分成单独的文件; 即：而不是在项目/ settings.py中的所有设置，我有几个设置文件像project / settings / dev.py。
我不得不从项目/ wsgi.py文件中更新DJANGO_SETTINGS_MODULE：
os.environ.setdefault("DJANGO_SETTINGS_MODULE", "project.settings")
至
os.environ.setdefault("DJANGO_SETTINGS_MODULE", "project.settings.dev")
然后gunicorn工作。
