I'm completely confused with multi site installation. I added a new directory (drupal-6.19/sites/newsite.com) and copied the install.php file into it. Bringing this up resulted in a bunch of errors for functions that could not be found. E.g.:
Warning: require_once(./modules/system/system.install) [function.require-once]: failed to open stream: No such file or directory in /home/user123/cms/drupal-6.19/install.php on line 26
Fatal error: require_once() [function.require]: Failed opening required './modules/system/system.install' (include_path='.:/usr/local/lib/php:/usr/local/php5/lib/pear') in /home/user123/cms/drupal-6.19/install.php on line 26
I've tried making install.php a copy of the original file or a symbolic link and neither works.
So I added symbolic links to all the required directories, but I get an error:
Requirements problem
The following errors must be resolved before you can continue the installation process:
* The Drupal installer requires that you create a settings file as part of the installation process.
1. Copy the ./sites/default/default.settings.php file to ./sites/default.
2. Change file permissions so that it is writable by the web server. If you are unsure how to grant file permissions, please consult the on-line handbook.
More details about installing Drupal are available in INSTALL.txt.
