After logging into your personal administration interface on http://1and1.fr, go to Manage pack tab to access information about your FTP access (Domain configuration), as well as database creation and configuration (MySQL administration).

You need a MySQL v5 database. If you don't have any yet, you should create one.

You also need to allow PHP 5 to run on your site. To do this, place an .htacess file in the root directory of your web site, containing:

AddType x-mapp-php5 .php

You should now rename inc/config.php.in to inc/config.php, then fill in the database details 1and1 provided.

This file configures access to the database.

The DC_ADMIN_URL should be the complete path to the administration interface of your Dotclear installation.

Open your browser and go to the admin/install directory of your Dotclear installation and fill out the form. Dotclear is now installed!

When your installation is finished and you have confirmed everything works, you can choose PATH_INFO format for your URLs and remove index.php from your blog URLs.

In the inc/config.php file, uncomment the four PATH_INFO lines near the end of the file, by deleting the double slashes ('/') at the beginning of each line.

Add the following lines to your .htaccess file:

# Get nice URLs with DotClear 2
RewriteEngine On
RewriteBase /
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule (.*) index.php/$1
RewriteRule ^index.php$  index.php/

Note: If you have placed DC2 in a subdirectory, replace the line

RewriteBase /

with

RewriteBase /subdirectory/

Go to your Dashboard, then to the Blog settings screen, and delete index.php/ from the end of the URL in the Blog URL field.
