Tutorial

There are a number of software packages maintained for compatibility with
CentOS that can be easily installed on your pairCloud server via the “yum”
command. Some common usages of that command are outlined at:

http://www.centos.org/docs/5/html/5.1/Deployment_Guide/s1-yum-useful-commands.html

To install a package on your CentOS pairCloud server, while logged in via
ssh, run the following replacing PACKAGE with the official name of the
package you would like to install:

sudo yum install PACKAGE

A listing of packages to be installed, including any dependencies will be
displayed. The amount of disk space required for the installation will
also be displayed. Enter ‘y’ to proceed with the installation.

The package will then be installed. That may take a few minutes to finish
depending on what is being installed.

The full usage of the yum command can be viewed at:
