Migrating your erpnext instance to wsgi

• Backup your database and files using: Tools > Download Backup

• Upgrade to Python 2.7+. Check your python version with this command, python -c "import platform; print platform.python_version()"

  • For CentOS, you can refer to http://toomuchdata.com/2012/06/25/how-to-install-python-2-7-3-on-centos-6-2/
  • For Ubuntu, refer to http://askubuntu.com/questions/101591/how-do-i-install-python-2-7-2-on-ubuntu/101595#101595 (if you are on Ubuntu 12.04 LTS or later, you already are on python 2.7, having two of those causes issues).

  Make sure you use altinstall so as not to break your existing operating system tools.

• Don't use lib/wnf.py for updating. Use git commands to pull updates in app and lib folders.

   cd app && git pull origin master && cd ..
   cd lib && git pull origin master && cd ..
   sudo pip install -r lib/requirements.txt
   ./lib/wnf.py --latest
   ./lib/wnf.py --build
  

• To update in future, you may use wnf.py pull,

   cd app && git pull origin master && cd ..
   cd lib && git pull origin master && cd ..
   ./lib/wnf.py --latest
   ./lib/wnf.py --build
  

Development Sever

• ./lib/wnf.py --serve

The serve command starts a development server on port 8000. You do not have to run apache server for development.
