I’ve just finished migrating more than a hundred websites to a new server only to find out that a couple of the migrated sites are still using Pear DB (database abstraction layer) package. So after spending a minute to install the package from the Web Host Manager (WHM), I decided to post this short-straight-to-the-point how-to on how to install it, and here it goes.

1. Login as root to your Web Host Manager (WHM), and on the left pane, look for the “Software” section.

2. Under the “Software” section, click on the “Module Installers”.

3. On the right pane, just below the search box, type in “DB” (without the quotes) and click on the “Install Now” button.

4. Once you have the package successfully installed, you should see the DB module on the list of installed PHP modules.

That’s all about it. Scripts that are referencing to this module should run now without errors at all.
