Installing Drupal

I just uploaded 7.0 to my host, setup the sql DB and renamed the default.settings.php to settings.php; However when I visit the site all I see is a login page for drupal, no install configuration and when I create an account via login page it reports it's not activated yet...also says it will be approved by a moderator? I also edited the settings.php to mimic the DB settings for MySQL, didn't make a difference either.

I installed drupal 6 onto www.reallylistedrealty.com as you can see something is wrong. can someone help me figure out what happened.

I installed Drupal 7 on a Red Hat Linux server and was not getting very far with it. I took a training class but the instructor used Drupal 6 and the interface is very different. So I thought my best approach would be to install Drupal 6. I downloaded and uncompressed the Drupal 6 core tar.gz file, and set up a new MySQL database 'drupal6' and granted privileges, and all that seemed to go OK. I copied default.settings.php to settings.php. I added the line $db_url = 'mysql://root:rootpw@localhost/drupal6'; When I run install.php from my browser I now get:

Drupal already installed
The following error must be resolved before you can continue the installation process:
In your ./sites/default/settings.php file you have configured Drupal to use a mysql server, however your PHP installation currently does not support this database type.
To start over, you must empty your existing database.
To install to a different database, edit the appropriate settings.php file in the sites folder.
To upgrade an existing installation, proceed to the update script.
View your existing site.
Please check the error messages and try again.

This is very confusing.
Is the installrefusing to proceed because there is another version of Drupal installed or because it thinks PHP does not support mysql?

I need to create two separate sites on my apache server. I have determined that I need to use a MULTIPLE sites set-up rather than a MULTI-SITE setup because I need to the domains to be different. For example:

Site 1: www.example.com

Site 2: www.test.com

Please am a newbie, I need help to add content to drupal 7 contact form. steps would be much appreciated.

I'm getting this error. This is a drupal 7.2 install on godaddy.
