CentOS source can not install libmcrypt-devel, due to copyright reasons do not have their own mcrypt package.

There are two ways to solve, one is to use a third-party source, so you can also use Yum to install, simple and convenient, the disadvantage is that the third-party source how much there is unreliable feeling.

Workaround One
1. Install a third-party yum Source
wget http://www.atomicorp.com/installers/atomic

2. Install with yum command
Yum Install Php-mcrypt Libmcrypt libmcrypt-devel
