I've finally gotten mysql figured out and have created a bare database called 'wordpress.' The wp-config.php file is where it should be and contains what it ought. Everything appears to be in place. Yet when I try to run wp-admin/install.php through Firefox, the browser just wants to open it as a text file.
What am I missing? I know PHP and MySQL are functioning; I used phpmyadmin to make the database.
I'm running Ubuntu 5.04, PHP 4.3.10 and MySQL 4.0.23, and Apache 1.3.33. I'm hosting locally.
