How do I install MCrypt on my server using Plesk?

MCrypt provides additional encryption for your site.  Magento requires it in order to run correctly, and other software packages may also require it.

It does not currently exist in the standard repositories for Plesk, but you can install a new repository from the command line and then install MCrypt onto your server fairly easily.

1. Open a command window into your server via SSH
2. Add the EPEL repository
3. Paste in:

wget http://dl.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm

4. Paste in:

rpm -Uvh epel-release-6-8.noarch.rpm

5. Install MCrypt using YUM by pasting in:

yum install mcrypt

6. MCrypt will now be installed and usable

If you need MCrypt for PHP, you can also add the Atomic Repository for php-mcrypt.

1. Log into your server via SSH
2. Add the atomic repository to your system with this line:

wget -O - http://www.atomicorp.com/installers/atomic |sh

3. Install php-mcrypt with this line:

yum install php-mcrypt

4. MCrypt will now be installed onto your server
