在Dreamhost上使用virtualenv更新新的Django和Python 2.7。*（带乘客）

Question

Dreamhost是小型项目的理想主机。而且它也是Django友好的托管。除python和Django版本外，其他所有功能都过时了。好吧，这是一整天的工作，要弄清楚如何在dreamhost上更新Python
2.7.3，Django 1.4，我真的想与任何发现它的人分享

Answer 1

我目前有私人服务器，一个外壳帐户和一点运气。所以这是我的工作：

1. SSH到您的主机以升级python

    cd ~
   

   mkdir tmp
   cd tmp
   wget http://www.python.org/ftp/python/2.7.3/Python-2.7.3.tgz
   tar zxvf Python-2.7.3.tgz
   cd Python-2.7.3
   ./configure –enable-shared –prefix=$HOME/Python27 –enable-unicode=ucs4
   make
   make install
   
   

2. 配置系统以使用我们的新Python。打开〜/ .bashrc并添加以下行

    export PATH="$HOME/Python27/bin:$PATH"
   

   export LD_LIBRARY_PATH=$HOME/Python27/lib

   #save it and run
   source ~/.bashrc

您现在可以使用检查您的python版本 which python

1. 安装easy_install，pip

   cd ~/tmp
   

   wget http://peak.telecommunity.com/dist/ez_setup.py
   python ez_setup.py
   easy_install pip

   wget https://bootstrap.pypa.io/get-pip.py
   python get-pip.py

2. 安装 virtualenv

    pip install virtualenv
   

   virtualenv $HOME/ /env
   #Switch to virtualenv
   source $HOME/ /env/bin/activate

您还可以将env路径添加到 bashrc

     export PATH="$HOME/<site>/env/bin/:$PATH"
 source ~/.bashrc

1. 安装Django和其他所有东西

    pip install django
   

   pip install ....
   pip install ....
   pip install ....

2. 建立专案

    cd $HOME/<site>/
   

   python $HOME/ /env/bin/django-admin.py startproject project

3. 创建passenger_wsgi.py于HOME/<site>/与下列内容

    import sys, os
   

   cwd = os.getcwd()
   sys.path.append(cwd)
   sys.path.append(cwd + ‘/project’) #You must add your project here or 500

   #Switch to new python
   #You may try to replace $HOME with your actual path
   if sys.version < “2.7.3”: os.execl(“$HOME/ /env/bin/python”,
   “python2.7.3”, *sys.argv)

   sys.path.insert(0,’$HOME/ /env/bin’)
   sys.path.insert(0,’$HOME/ /env/lib/python2.7/site-packages/django’)
   sys.path.insert(0,’$HOME/ /env/lib/python2.7/site-packages’)

   os.environ[‘DJANGO_SETTINGS_MODULE’] = “project.settings”
   import django.core.handlers.wsgi
   application = django.core.handlers.wsgi.WSGIHandler()

或者这样

import sys, os

BASE_DIR = os.path.dirname(os.path.abspath(__file__))

sys.path.append(os.path.join(BASE_DIR))  #You must add your project here or 500

#Switch to new python
#You may try to replace $HOME with your actual path
PYTHON_PATH = os.path.join(BASE_DIR, 'env', 'bin', 'python')
if sys.executable != PYTHON_PATH:
    os.execl(PYTHON_PATH, "python2.7.12", *sys.argv)

如果您使用的是django 1.7，请将最后两行替换为

from django.core.wsgi import get_wsgi_application
application = get_wsgi_application()

1. 享受：D

Dreamhost上的新版本python将不再返回，sys.executable因此您这是我的passenger_wsgi版本

import sys, os

VIRTUAL_ENV_PYTHON = 'venv-python'  # Python > 2.7.6 dreamhost not return sys.executable
BASE_DIR = os.path.dirname(os.path.abspath(__file__))

def is_venv_python():
    if len(sys.argv) > 0:
        last_item = sys.argv[len(sys.argv)-1]
        if last_item == VIRTUAL_ENV_PYTHON:
            return True
    return False

sys.path.append(os.path.join(BASE_DIR))  #You must add your project here or 500

#Switch to new python

PYTHON_PATH = os.path.join(BASE_DIR, 'env', 'bin', 'python')
if not is_venv_python():
    os.execl(PYTHON_PATH, "python2.7.12", *sys.argv + [VIRTUAL_ENV_PYTHON])

sys.path.insert(0, os.path.join(BASE_DIR, 'env', 'bin'))
sys.path.insert(0, os.path.join(
    BASE_DIR, 'env', 'lib', 'python2.7', 'site-packages'
))
