Python 使用openshift部署本地django应用程序

我用django构建了一个Web应用程序。为了托管它，我正在尝试使用openshift，但很难让任何东西正常工作。这方面似乎缺乏一个循序渐进的步骤。到目前为止，我已经让git运行良好，该应用程序可以在本地开发环境下运行，并且我已经成功地在openshift上创建了一个应用程序

根据openshift上的URL，一旦创建，我就会得到“欢迎使用您的openshift应用程序”的标准页面

我遵循这一点尝试更改wsgi.py文件。将其更改为hello world，推送它，但我仍然得到openshift默认页面

是否有一个很好的综合资源可以让本地Django应用程序在Openshift上启动和运行？我在谷歌上能找到的大部分只是示例应用程序，这些应用程序并没有我自己开发的那么有用。

1）步骤1安装Rubygems
1)  Step 1 install  Rubygems
Ubuntu - https://rubygems.org/pages/download
Windows - https://forwardhq.com/support/installing-ruby-windows
$ gem
or
C:\Windows\System32>gem
RubyGems is a sophisticated package manager for Ruby.  This is a
basic help message containing pointers to more information……..

2)  Step 2:
$ gem install rhc
Or
C:\Windows\System32> gem install rhc

3)  $ rhc
Or
C:\Windows\System32> rhc

Usage: rhc [--help] [--version] [--debug] <command> [<args>]
Command line interface for OpenShift.

4)  $ rhc app create -a mysite -t python-2.7
Or 
C:\Windows\System32>  rhc app create -a mysite -t python-2.7
# Here mysite would be the sitename of your choice
#It will ask you to enter your openshift account id and password

Login to openshift.redhat.com: Enter your openshift id here

packages=['Django编辑：请记住，这是一个依赖于平台的答案，由于服务于Django的OpenShift平台可能会发生变化，此答案可能会无效。截至2016年4月1日，此答案在整个范围内保持有效

这在我身上发生过很多次，因为我必须装载至少5个应用程序，所以我必须创建自己的生命周期：

不要使用Django盒带，而是使用Python2.7盒带。使用Django购物车。尝试更新Django版本会带来很多麻烦，如果从头开始，则不包括在内
通过git克隆您的存储库。您将获得
yourproject
和

# git clone yourrepo@rhcloud.com:app.git yourproject <- replace it with your actual openshift repo address

yourproject/
+---wsgi.py
+---setup.py
*---.openshift/ (with its contents - I omit them now)


在那里创建一个django应用程序。比如说，你的应用程序。将它包含在你的项目中

您将有如下内容（django 1.7）：


像往常一样设置django应用程序（我不会在这里详细介绍）。记住在setup.py文件中相应地包含您安装的所有依赖项（这个答案不是解释原因的地方，但setup.py是软件包安装程序，openshift使用它在每次部署时重新安装应用程序，因此请使其与依赖项保持同步）

为模型创建迁移
按如下所示编辑给定WSGI脚本的openshift。在包含virtualenv（openshift为python盒带创建一个）之后，您将包含django WSGI应用程序，因此将正确设置pythonpath

#!/usr/bin/python
import os
virtenv = os.environ['OPENSHIFT_PYTHON_DIR'] + '/virtenv/'
virtualenv = os.path.join(virtenv, 'bin/activate_this.py')
try:
    execfile(virtualenv, dict(__file__=virtualenv))
except IOError:
    pass

from yourdjproject.wsgi import application


编辑.openshift/action_hooks中的hooks以自动执行数据库加密和媒体管理：

造钩

#!/bin/bash
#this is .openshift/action/hooks/build
#remember to make it +x so openshift can run it.
if [ ! -d ${OPENSHIFT_DATA_DIR}media ]; then
    mkdir -p ${OPENSHIFT_DATA_DIR}media
fi
ln -snf ${OPENSHIFT_DATA_DIR}media $OPENSHIFT_REPO_DIR/wsgi/static/media

######################### end of file

展开挂钩

#!/bin/bash
#this one is the deploy hook .openshift/action_hooks/deploy
source $OPENSHIFT_HOMEDIR/python/virtenv/bin/activate
cd $OPENSHIFT_REPO_DIR
echo "Executing 'python manage.py migrate'"
python manage.py migrate
echo "Executing 'python manage.py collectstatic --noinput'"
python manage.py collectstatic --noinput

########################### end of file


<> L> > p>现在你已经准备好了，通过导入指向Django WSGi，并且你有你的脚本在运行。是时候考虑我们在这些脚本中使用的静态和媒体文件的位置了。编辑你的Django设置，告诉你你想在哪里找到这样的文件：

STATIC_URL = '/static/'
MEDIA_URL = '/media/'
STATIC_ROOT = os.path.join(BASE_DIR, 'wsgi', 'static')
MEDIA_ROOT = os.path.join(BASE_DIR, 'wsgi', 'static', 'media')
STATICFILES_DIRS = (os.path.join(BASE_DIR, 'yourjdproject', 'static'),)
TEMPLATE_DIRS = (os.path.join(BASE_DIR, 'yourjdproject', 'templates'),)


创建示例视图、示例模型、示例移植，并推送所有内容
