Looking through the documentation, I can only find reference to cases where SS is set up once on a server, usually in a directory that is directly below the root, eg. C:\wamp\www\silverstripe

Is it possible to install many instances of SS on the same server, in a structure that would look a bit like this:

www/
----site01/
--------silverstripe/
----site02/
--------silverstripe/
----etc...

I tried it but when I tried to access the first one I was getting 403 (Permission denied) errors everywhere.

Before I start messing around with Apache, can someone confirm that it is in fact valid to install many SSs like this?

Do you mean totally separate copies of SilverStripe, eg. each install has its own cms, sapphire etc. folders? If yes, that's as simple as copying the files over to the webserver. Should work without any problem actually.. you have to alter the .htaccess file after the move though (change the RewriteBase to the appropriate path). And every installation needs it's own Database.

If you want to use the same SilverStripe code-base (sapphire, cms etc) for multiple sites, you should use symlinks (more info in this thread: http://silverstripe.org/general-questions/show/251650). I don't know a good windows pendant to symlinks though.

Yes works fine. I use subfolders for my local host and for my live server. On my live server I use VirtualHosts to point to correct location, on my local having sub folders works fine. You might need to configure the RewriteRule in the .htaccess file.

Thanks guys!

Yep it all seems to work fine.

For anyone else looking for the same answer, I simply moved my entire installation down one directory level to, in my case, www/site01/silverstripe/ .

I then edited the \SilverStripe\.htaccess file, altering
RewriteBase /SilverStripe
to
RewriteBase /site01/SilverStripe

Next, to prevent users accessing the directory structure higher up the tree, I edited my apache httpd.conf file adjusting the 'Deny from all' and 'Allow from 127.0.0.1' for each parent directory as appropriate (your chosen settings will almost certainly be different to mine, just play around until you get works best for you).

Viola! It all came up fine.

I haven't set up a second installation yet in parallel, but I'm assuming it'll be fairly straight forward. If I come across any gotchas I'll post them here.
