To install htop to Redhat or CentOS Linux easily via the yum package manager. However sometimes it happens that yum repository doesn’t have that package, so the rpmforge package repository must be installed first. To install, retrieve, and install the following RPM for your architecture (32bit or 64bit).
wget http://packages.sw.be/rpmforge-release/rpmforge-release-0.5.2-2.el5.rf.i386.rpm rpm -Uhv rpmforge-release*.rf.i386.rpm
wget http://packages.sw.be/rpmforge-release/rpmforge-release-0.5.2-2.el5.rf.x86_64.rpm rpm -Uhv rpmforge-release*.rf.x86_64.rpm
Now that the rpmforge repository is installed, you can install the htop package easily via yum.
yum install htop
