Installing & Running Drupal 5.7 on 1and1

Installation error message on 1and1:
Incompatible environment
The following error must be resolved before you can continue the installation process:
register_globals is enabled. Drupal requires this configuration directive to be disabled. Your site may not be secure when register_globals is enabled. The PHP manual has instructions for how to change configuration settings. (Currently using PHP register globals Enabled ('1'))

is solved the following way:
In a simple text editor, sopy and paste the following data:
register_globals = Off
memory_limit = 12M

and save it as php.ini
in your Drupal 5.7 directory on your hard disk.

Upload the php.ini file on your online Drupal directory, in the root folder

INSTALL DRUPAL MULTI-SITES ON 1AND1 USING SINGLE DATABASE

Example: installing sub.example.com in the main, example.com Drupal 5.7 site (you can add as many sites as you like)

1. In your Drupal up and running online site, example.com, using FTP client, find the folder 'sites' and enter it. You'll see two folders: 'all' and 'default'. Create new folder naming it 'sub.example.com'

2. Into this folder, create 4 folders, naming them: files, modules, themes and temp

3. also, from your Drupal folder on your hard disk, upload the file settings.php (found in /sites/default directory); this is a fresh 'settings.php' file, thus unmodified

4. In the 1and1 Control Panel => Domains => select (click the box on the left) the sub.example.com domain name, and on the top of the page select 'Edit Destination'

5. (still on 1and1) On the next screen there are two options: Select Destination Type (=home directory) and 'Home Directory'. There are two buttons in Home Directory: select 'Existing directory' in the top button; in the lower button, click and find the 'example.com' directory; click OK; this step is the crucial - don't forward your sub.example.com site, but let it point to your main installation, main Drupal site.

6. Navigate your browser to sub.example.com & the familiar Drupal installer should appear. Put the same MySQL Database info (as in example.com), and click the Advanced button: put the database url AND the Database prefix (this is crucial step - just invent any prefix, any name and put it there, in the last field.)

This article is for enabling the clean Urls to work on 1and1 server. To understand and enable clean urls, click here: http://drupal.org/node/15365

1. In you Drupal directory, on your hard disk, open the ".htaccess" file using a simple text editor.

find the following place:

# Modify the RewriteBase if you are using Drupal in a subdirectory or in a
# VirtualDocumentRoot and the rewrite rules are not working properly.
# For example if your site is at http://example.com/drupal uncomment and
# modify the following line:
# RewriteBase /drupal
#
# If your site is running in a VirtualDocumentRoot at http://example.com/,
# uncomment the following line:
# RewriteBase /

Now, uncomment the last line. Meaning, delete the hash in front of the # RewriteBase /

So, the code should look like this:

# Modify the RewriteBase if you are using Drupal in a subdirectory or in a
# VirtualDocumentRoot and the rewrite rules are not working properly.
# For example if your site is at http://example.com/drupal uncomment and
# modify the following line:
# RewriteBase /drupal
#
# If your site is running in a VirtualDocumentRoot at http://example.com/,
# uncomment the following line:
RewriteBase /

Save the file, and upload it to your Drupal web-folder, replacing the .htaccess file found there

Test the clean urls - they should now work.

1and1.co.uk DOESN'T let you access and modify Cron. Other solutions seem too complicated. Best bet is http://webcron.org.
It's initially in French, but there's English version (click on the small flag at the bottom).

Works perfectly!
