If these are RedHat servers, this doc should help.

Or for CentOS 7, you can download the packages from here,
http://mirror.centos.org/centos/7/os/x86_64/Packages/

Or just modify the above URL for CentOS 6 rather than 7.

Still assuming CentOS, once you have the package on the system, you can just do an rpm -i <packagename> and it will install the package. Unfortunately you're going to have to satisfy any dependencies, so be prepared to run back out to the internet for more packages.
