Multiple Sites Based on Identical Configurations

This may be a strange topic, but I wanted to configure our access into subdomains, all with SSL access. We needed different sites because SSL forces IP based virtual domains, which meant different document roots for us. Such as:


However, these were all sites with the same core schema and plugins. The advantage of this configuration is:

  • Shared model files: All the XxxPeer classes will be linked across applications


  • You now have 2-n different caches/logs to monitor.

If you look at a typical Symfony directory structure, it can be broken up to two type groups:

  • Common Directories:
    • batch
    • config
    • data
    • doc
    • lib
    • plugins
    • test
  • Application Specific Directories:
    • apps
    • cache
    • log
    • web

Here are the steps I took:

  • Develop the schema and site. Once this is starting to come together, you can start to develop the additional sites.
  • In the new site, symbolic link the Common Directories
  • In the new site, create the Application Specific Directories
    • NOTE: In the web directory, you may need to copy some of the original contents (css, js, and .htaccess files come to mind). Keep this in the back of your mind as you start to bring up the new site.
  • Run the command **symfony fix-perms**
    • NOTE: For me, Virtualmin creates these new sites with new usernames. You will have to insure that all the Application Specific Directories are owned by that username, so your clear-cache commands and logging commands work.
  • Now, you have a the project configured. You start by doing:
    • symfony app MYAPP
    • symfony module MYAPP MYMODULE
    • ...
  • You will now find that your apps/MYAPP/modules/MYMODULE has been created, and you have full peer access to the entire database
