HTOP on CentOS 7: How to Compile from Source

HTOP is an interactive process viewer similar to the top command installed in all Linux distributions.  It is a free (GPL) process viewer based on the ncurses library. In the most basic sense, top and HTOP are the same except for certain extra functions such as the vertical and horizontal scroll. HTOP also displays all processes, command lines, and process trees running in the system. Unfortunately, HTOP is not installed by default in CentOS 7. There are two ways to install it. The first way is through the epel repository. The other is by compiling the facility from source. This article focuses on the latter and demonstrates the process in detail.

Gammu-SMSD: Command Not Found [Solved]

This article details the steps to Build a Centos 7 SMS Gateway from Source.

Centos 7 Quickfixes

Two years ago (2014), I wrote the article “CentOS 6.5 Configuration Tips” to document the steps I take in building a CentOS 6.5 server. Through the years, it has saved me a lot of time in rolling out custom CentOS builds for client requirements. Truth be told, the article is a life saver. It allows me to build, customize, deploy, and deliver servers consistently all-the-time every time. Likewise, my coworkers benefit from the article because it provides a simple guide on how to install frugal CentOS 6.5 builds. Of course, at the end of the day, when they give me a properly configured server build, I benefit.

However, like everything else in the IT, things change quite quickly. Usually, there are minute changes here and there which may be annoying at times but are totally tolerable. But there are times, such as the case at hand, where the annoyances turn into complete nuisances.

To cut the story short, CentOS 7 is a substantial departure from CentOS 6.5. This departure makes the 2014 article on “CentOS Configuration Tips” partially obsolete. Thus, a new guide is warranted.
