Is there any update to this if using 2.4 r2?
I am considering this for my clients and possibly the following setup.

All admin done via one domain ""
I think I can program the ability to redirect a client to the "" if they try to come into admin via ""
All images and files are hosted on Amazon s3 so that probably would mean not changing the image file.
But how do I handle different modules for different clients?

Any suggestions where to start here?

created folder and copied files, created symlink as suggested from Juanitou. Now I stuck with the BASE_PATH. Where do I have to correct it? And what is it supposed to say?

Have an "application"-folder "silverstripe" in the root of my testserver with subfolder cms and sapphire. have a "website"-folder ss_one for the first site (will have folder ss_two etc. for other websites) and in this I have the symlinks to cms and sapphire and subfolder assets, mysite and themes.

when I try to open the site I get the error:

$project isn't set in /Applications/XAMPP/xamppfiles/htdocs/silverstripe/sapphire/core/ManifestBuilder.php on line 259

and I see the typical error site, with "Cannot modify header information...".

Does this error come from the information BASE_path or is there another problem? Thanks for any help :-)

bye - nina

It's a little different in 2.4. The BASE_PATH constant is not calculated the same way. The fix is to create an index.php file in your site root:


define('BASE_PATH', dirname(__FILE__));
include ('sapphire/main.php');


And update your .htaccess file to point to that instead of sapphire/main.php.

There's a better way. Use [url=]_ss_environment.php[/url] to your advantage.

In your SilverStripe 2.4 base folder, create a file called _ss_environment.php and put the following line in it:

define('BASE_PATH', rtrim(dirname(dirname($_SERVER['SCRIPT_FILENAME'])), DIRECTORY_SEPARATOR));

Of course you are free to also add DB information that all your installations share, as described on the doc page above.

Then simply put the following line into mysite/config.php


That's all. Works a charm here... here's how my file-structure of a typical site looks like:

BaseInstall2.4.1 (silverstripe codebase)
   +- sapphire
   +- cms
   +- googlesitemaps
   +- dataobject_manager
   +- swfupload
   +- _ss_environment.php (as described above)
SomeSite (all website folders are structured like this)
   +- sapphire (symlinked to BaseInstall2.4.1/sapphire)
   +- cms (symlinked to BaseInstall2.4.1/cms)
   +- googlesitemaps (symlinked to BaseInstall2.4.1/googlesitemaps)
   +- dataobject_manager (symlinked to BaseInstall2.4.1/dataobject_manager)
   +- swfupload (symlinked to BaseInstall2.4.1/swfupload)
   +- assets own asset folder for each site
   +- mysite own mysite folder for each site
      +- _config.php as described above

So all websites are structured like SomeSite and have only a custom assets and mysite folder, but otherwise share the same codebase.

Banal's right.. that's the pro way to do it.

what about uploading stuff? i remembered last time i made that, when the editor uploaded a file sapphire started with the problems..

@dospuntocero: Uploading should work fine. Never had problems with it (I always use a separate assets folder for each install and set it's permission bits to 0777).
