gunicorn.errors.HaltServer：<haltserver'worker =“”failed =“”to =“”boot。'=“”3 =“”> django </haltserver>

标签： python django gunicorn

我有一个django应用程序，并尝试先用gunicorn设置它，然后再用supervisor和nginx设置它。

该应用程序正常运行时使用正常的django命令，就像python manage.py runserver

一样

我使用像pip install gunicorn这样的pip安装了gunicorn，而django版本是1.5.3

当我在虚拟环境中运行以下命令时，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')()

    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？

答案 0 :(得分：26)

实际上这里的问题是wsgi文件本身，之前在django 1.3之前，wsgi文件的扩展名为.wsgi，但现在在最近的版本中，它将使用{{1}的扩展名创建那就是wsgi文件必须是python模块

所以文件应该是.py，命令应该是

hello_wsgi.py

您没有显示完整输出。它可能看起来像

$(function() {
$('.monthYearPicker').datepicker({
    changeMonth: true,
    changeYear: true,
    showButtonPanel: true,
    dateFormat: 'MM yy'
}).focus(function() {
    var thisCalendar = $(this);
    $('.ui-datepicker-calendar').detach();
    $('.ui-datepicker-close').click(function() {
        var month = $("#ui-datepicker-div .ui-datepicker-month :selected").val();
        var year = $("#ui-datepicker-div .ui-datepicker-year :selected").val();
        thisCalendar.datepicker('setDate', new Date(year, month, 1));
        });
    });
});

最后的引用几乎相同，但在您看到所需的信息之前：

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

如果您看到此错误，则解决方案是使用ImportError: No module named elcarweb.wsgi 参数运行gunicorn。

我在使用systemd的Ubuntu 16.04，Django 1.11中也有类似的错误。

我的问题是我将设置拆分为单独的文件;即：我没有在project / settings.py中设置所有设置，而是有一些设置文件，如project / settings / dev.py。

我必须更新项目/ wsgi.py文件中的DJANGO_SETTINGS_MODULE：

os.environ.setdefault("DJANGO_SETTINGS_MODULE", "project.settings")

到

os.environ.setdefault("DJANGO_SETTINGS_MODULE", "project.settings.dev")
然后枪手工作了。

使用--preload运行guncorn可以看到错误日志，例如

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

这通常会为您提供更详细的错误消息。

答案 4 :(得分：1)

我得到了同样的错误。 Gunicorn在以root身份执行时正在工作，但在以非特权用户身份执行时以这种方式失败。 在我的情况下，我使用'pip install dataset'安装'dataset'python模块，它将/usr/lib/python2.7/site-packages/dataset上的权限搞砸，只能由root帐户读取。在其他模块上安装为依赖，就像是正常一样。

修复：

chmod -R a+rX /usr/lib/python2.7/site-packages/dataset*
chmod -R a+rX /usr/lib/python2.7/site-packages/normality*

另一个问题是由pip自动安装的yaml包，但我还没有找到确切的内容。修复是从fedora包重新安装：

dnf -y install python-yaml

答案 5 :(得分：0)

对于面临相同问题的任何人，问题通常出在Django本身中。 激活您的venv并运行./manage.py runserver

这通常会为您提供更详细的错误消息。
