Installing htop

Jan 2017

By Default, htop is not installed on Linux, it is not part of a minimal install on a software only ISO (although a customer could have added it themselves)
On a brand new Linux, you will have to either:
Update the repositories to be able to install htop, please check out this wiki page first (or the install will fail)
CentOs 7 no WGET install EPEL
Or
Just download the htop library, and install that

curl -O https://dl.fedoraproject.org/pub/epel/7Server/x86_64/h/htop-2.0.2-1.el7.x86_64.rpm

The above example is for CentOS 7, use the correct path for your CentOS version
Bear in mind that the htop version might change
