Gunicorn`无法连接到('ind',8000)` - Django,EC2,Nginx

Question

这似乎在今天早些时候工作,我不知道发生了什么变化.我对部署非常缺乏经验,所以这可能是我所缺少的最简单的事情.

我在EC2上使用默认的Amazon Linux映像.在新创建的实例中,输入的命令如下:

yum search python34 #Amazon Linux doesn't have 3.5 yet
sudo yum install python34-virtualenv
sudo alternatives --set python /usr/bin/python3.4
virtualenv-3.4 env
sudo pip install --upgrade pip
hash -r
sudo ln -s /usr/local/bin/pip /usr/bin/pip

sudo pip install django
django-admin.py startproject MyApp
cd MyApp
python manage.py runserver #This gives me ERR_CONNECTION_REFUSED in Chrome on port 8000, but worked earlier

sudo yum install nginx
sudo service nginx start #This works, I'm able to see the default page on default port
sudo service nginx stop

sudo pip install gunicorn
gunicorn -bind 0.0.0.0:8000 MyApp.wsgi:application #This doesn't even start

以下是上一个命令的结果:

[ec2-user@ip-172-31-48-233 MyApp]$ gunicorn -bind 0.0.0.0:8000 MyApp.wsgi:application
[2015-11-20 19:16:36 +0000] [2547] [INFO] Starting gunicorn 19.3.0

[ec2-user@ip-172-31-48-233 MyApp]$

我现在很迷茫,找不到太多最新的资源来指导我完成这个过程的细节.任何帮助将不胜感激,谢谢.

参数是-b或--bind不是-bind.
