Update new Django and Python 2.7.* with virtualenv on Dreamhost (with passenger)

Dreamhost is a great host for small project. And it's also Django friendly hosting. Everything good except python and Django version is a little bit out of date. Well it's a whole day of work to figure out how to update Python 2.7.3, Django 1.4 on dreamhost and I really want to share with whoever finding it

Answer Source

I currently have private server, a shell account and a bit of luck. So here is what I do:

  1. SSH to your host to upgrade python

     cd ~
     mkdir tmp
     cd tmp
     tar zxvf Python-2.7.3.tgz
     cd Python-2.7.3
     ./configure --enable-shared --prefix=$HOME/Python27 --enable-unicode=ucs4
     make install
  2. Configure system to use our new Python. Open ~/.bashrc and add the following line

     export PATH="$HOME/Python27/bin:$PATH"
     export LD_LIBRARY_PATH=$HOME/Python27/lib
     #save it and run
     source ~/.bashrc

    you can now check your python version with which python

  3. Install easy_install, pip

    cd ~/tmp
    easy_install pip
  4. Install virtualenv

     pip install virtualenv
     virtualenv $HOME/<site>/env
     #Switch to virtualenv
     source $HOME/<site>/env/bin/activate

    you can also add env path to bashrc

     export PATH="$HOME/<site>/env/bin/:$PATH"
     source ~/.bashrc
  5. Install django and everything else

     pip install django
     pip install ....
     pip install ....
     pip install ....
  6. Create project

     cd $HOME/<site>/
     python $HOME/<site>/env/bin/ startproject project
  7. Create in HOME/<site>/ with following content

     import sys, os
     cwd = os.getcwd()
     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/<site>/env/bin/python",
         "python2.7.3", *sys.argv)
     os.environ['DJANGO_SETTINGS_MODULE'] = "project.settings"
     import django.core.handlers.wsgi
     application = django.core.handlers.wsgi.WSGIHandler()

If you are using django 1.7, replace the last two line with

from django.core.wsgi import get_wsgi_application
application = get_wsgi_application()
  1. Enjoy :D
