CentOS: Enabling GD Support in PHP Installation

Question

How do I go about enabling GD Support in a CentOS Installation?

Answer 1

With CentOS 6.5+ and PHP 5.5:

yum install php55u-gd
service httpd restart

If you get an error like: cannot map zero-fill pages: Cannot allocate memory in Unknown on line 0, it could be because you don't have a swap file. I suggest you take a look at the tutorial mentioned in this answer: https://stackoverflow.com/a/20275282/828366
