To enable Python or Ruby on a shared hosting environment instead of a dedicated VPS environment, CloudLinux Python and Ruby Selector is recommended. If it is not for a shared hosting environment, you can refer to our archive section for LSWS native setup.

The Python and Ruby Selector allows end users to select the specific version of Python or Ruby they need.

• LiteSpeed Web Server 5.2+
• CloudLinux

1. Make sure Python and Ruby Selector works properly under Apache (follow CloudLinux instructions to install and configure).
2. Test a Ruby or Python application with Apache and ensure it is running OK.
3. Run script to install required ruby/python lsapi modules:

   /usr/local/lsws/admin/misc/enable_ruby_python_selector.sh

4. Switch to LiteSpeed and try a ruby/python app

If your application does not work properly, you can try two simple steps to check if the application has been setup properly:

1. If possible, switch back to Apache temporarily to verify if the application works properly under Apache.
2. Check if any error has been logged into <APP_ROOT_DIR>/stderr.log. If it has, fix the error and try again.

For example:

A Python application writes an error to stderr.log under the application root directory, /home/user1/dingodossier/mbntp/stderr.log:

Traceback (most recent call last):
  File "/home/user1/dingodossier/mbntp/passenger_wsgi.py", line 8, in <module>
    wsgi = imp.load_source('wsgi', 'mbntp/wsgi.py')
  File "/home/user1/virtualenv/dingodossier_mbntp/3.4/lib64/python3.4/imp.py", line 171, in load_source
    module = methods.load()
  File "<frozen importlib._bootstrap>", line 1220, in load
  File "<frozen importlib._bootstrap>", line 1200, in _load_unlocked
  File "<frozen importlib._bootstrap>", line 1129, in _exec
  File "<frozen importlib._bootstrap>", line 1471, in exec_module
  File "<frozen importlib._bootstrap>", line 321, in _call_with_frames_removed
  File "mbntp/wsgi.py", line 10, in <module>
    from django.core.wsgi import get_wsgi_application
ImportError: No module named 'django'

This indicates Django was not properly set up for the application.
