Almost tried everything searched on Google, Most of the time when i wrote commands on Terminal it says no package available, My VPS is unmanaged and therefore the host won't support for this
The easiest way to do it, with CentOS, is via RPM. I know most of what is on Google (including RPM links and yum installation guides) no longer works. This repository has working links... http://www.rpmfind.net/linux/rpm2html/search.php?query=htop You'll want one of the .el5 versions (most likely, depending on your OS version). Then you'll want to wget the file from the location via SSH: wget "" Then, run (as either root or sudo) rpm -Uvh PACKAGE.rpm on the file, should install and make htop available.
or just install dag's repo, then you can easily install it with "yum install htop" it will be there..
