Errors we have run into and what we did to fix them.
If you have useful information, pass it along! We will post it and give you credit as well.
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.
I just installed MySQL, PHP, and Drupal-6.9. PHP and MySQL were installed using 'yum'. I created a new database and copied another site from my test server as a starting template. I tried to just hit the URL and got the site offline message.
The site is currently not available due to technical problems. Please try again later. Thank you for your understanding.
Well, it was pretty easy for me on CentOS. It helps if you remember to install all the components!
yum install php-mysql
You might want to install php-gd and php-mbstring too if you have not already. Give MySQL and Apache a restart and just try it again. Voila!
