How to run multiple Django programs concurrently on the Apache server

It is entirely possible to run multiple Django programs in the same Apache instance. You might want to do this when you are a standalone WEB developer and have multiple different customers.

As long as you use VirtualHost like this, you can achieve:

Namevirtualhost *
 
  
   
    ServerName www.example.com  #  ... SETENV django_settings_module mysite.settings
 
  
 
  
   
    ServerName www2.example.com  # ...  SETENV django_settings_module mysite.other_settings
 
  

If you need to run two Django programs in the same VirtualHost, you need to pay special attention to ensure that the Mod_python code cache is not messed up. Use the Pythoninterpreter directive to interpret the different instructions separately:

 
  
   
    ServerName www.example.com  # ...  
  
   
    
       SetEnv django_settings_module mysite.settings    pythoninterpreter mysite  
  
     
  
   
    
       SETENV django_settings_module mysite.other_settings    pythoninterpreter mysite_other  
  
   
 
  

The values in this pythoninterpreter are not important, as long as they are different in two location blocks.
