Question

我确定这是我的错，但我的系统已经工作了好几个月，现在却无法正常工作。我已经查看了Django文档，并在此处查看了stackoverflow，我理解了连接被拒绝的问题＆＃39;意味着没人在听插座;但我不明白为什么，也不知道如何前进。

我在MacPro上使用Vagrant + VirtualBox，六个月以来，我已经能够创建虚拟机并运行我的应用程序而没有任何问题。我有一些虚拟机，一切都按预期工作。

在我新创建的Vagrant虚拟机上，我安装并配置我的django应用程序并使用＆＃39; python manage.py runserver运行它们--settings = mumble.settings.py 0.0.0.0:8000&# 39 ;.请注意，这是Django 1.8.3，但同样，它在某些VM上运行良好。

出于神秘的原因，当我创建一个新的流浪汉VM并安装我的django有效载荷（使用尚未更改的部署脚本），并连接到django服务器时，我得到Errno 111 Connection拒绝：

我知道的事情：

＆＃39; python ./manage.py'没有参数将运行正常，并显示帮助消息。
对Web服务器进行寻址的所有形式都将失败：
- curl http://localhost:8000
- curl http://127.0.0.1:8000
- curl http://192.168.33.10:8000
- 来自浏览器：http://192.168.33.10:8000
nginx正在端口80上服务，没问题
我的数据库是生产数据库的副本，通过＆＃39; mysql＆＃39;

这是一个奇怪的事情：我放下了Django教程，使用了＆＃39; runserver＆＃39;命令，它工作了！

[vagrant][~/tmp/django_tutorial/mysite]
$ python manage.py runserver 0.0.0.0:8000

有关如何调试的建议吗？

Answer 1

答案与我的环境无关。我的同事在settings.ADMINS中添加了一个名称，之前一直是一个空列表。当ADMINS是非空列表时，任何错误都会触发尝试向ADMINS中的所有电子邮件地址发送电子邮件，并且我的VM未配置为发送电子邮件。这是有记录的，但没有强调。问题没有发生在我的同事那里，因为相关的更改没有触发服务器错误。

Django + Vagrant VM突然说Errno 111：连接被拒绝
