Install GD Library For PHP5 On CentOS

Note: this article only applies if your current PHP version has been installed by yum. If you custom compiled it from source, this will not work.

Verify PHP as installed by yum

An easy task, using yum. First step, see if it's already installed.

[root@srv]# rpm -qa | grep php
php-common-5.1.6-15.el5
php-cli-5.1.6-15.el5
php-5.1.6-15.el5
php-pdo-5.1.6-15.el5
php-mysql-5.1.6-15.el5

Install the GD library using yum

If the GD Library isn't present in that list, it wasn't installed on the server yet. Install it using yum.

[root@srv]# yum install php-gd
