General index of the series: Computer Networks for SMEs: Introduction
I transcribe here the first paragraph of the site wiki.centos.org About this large distribution:
- CentOS Linux is a community-maintained distribution derived from source packages released to the public by Red Hat for Red Hat Enterprise Linux (RHEL). Thus, CentOS Linux is focused on being operationally compatible with RHEL. The CentOS Project primarily changes packages to remove Red Hat's trademarks and artwork. CentOS Linux redistribution is free and you don't have to pay for it. Each version of CentOS is maintained for 10 years (by means of security updates - the duration of the maintenance intervals have varied over time in relation to the released source packages). A new version of CentOS is released approximately every 2 years and each version of CentOS is periodically updated (every 6 months) to incorporate new hardware. This results in a secure, low-maintenance, reliable, predictable, and reproducible Linux environment.

Why will we also write about CentOS?
In my country, Cuba, I dare to affirm that, the Linux distributions most used today at the enterprise level on servers are CentOS, Ubuntu, Debian, and in Internet access providers, FreeBSD. Distributions are also used RHEL, OpenSUSE, SUSE and others. There is a strong use of distros .deb y . Rpm.
In any case, I have not read Official Statistics on the use of Free Software in my country, which does not mean that they do not exist. A serious study on the subject can be found on the site GUTL from Cuba.
What happens in my particular case?
On many occasions I have read comments that, in DesdeLinux, it only writes about Ubuntu or Debian. Personally, my experience in production is mostly with Debian and apparently that fact has greatly influenced my writing.
There is also the other aspect of the documentation available in Spanish about Debian GNU / Linux. As it is quite scarce, I have tried to there is more available to interested parties.
It is known to many that there are excellent articles, wikies, forums, sites, etc., dedicated to the documentation of distributions such as RHEL, Fedora, Ubuntu, and in general for less related distributions, to put it in some way and without any offense, with the Full Spirit of Free Software.
I think the main cause of the excellent documentation is that the distribution RHEL is from the Company Red Hat Inc.; Ubuntu is financed by the Company rectoryl; the project CentOS reflects on its homepage the importance of its Sponsors - Sponsors in its development, while Fedora -distro oriented to desktops- is directly sponsored by the Red Hat Inc. Company. It has to do -and a lot- with the technical support offered to its customers.
If you want to get an idea of what I mean, treat yourself to a couple of visits per Making Wireless work on your laptop (or desktop) full wiki.centos.org, and the other for wireless full wiki.debian.org.
Debian GNU / Linux, The Universal Operating System, It is a Project mainly carried out by volunteers, even if it has its sponsors. As a Project it is very clearly defined in its Debian Social Contract.
What will we do in future articles?
After the part dedicated to Virtualization ends, we will write the same articles for that part, plus the one dedicated to the topic of desktops, about CentOS.
I think that with this strategy, package-oriented distributions are covered .deb and . Rpm. On the other hand, in one way or another, we will be referring to backbone or older distributions within the Linux universe.
I hope to please many readers with this new endeavor. You deserve it. We deserve your feedback, via comments and / or emails.
Greetings to all readers!.
We will also include the distribution OpenSUSE on the occasion of the Computer Networks for SMEs. What do you think?.
Welcome to OpenSUSE
Congratulations, it was necessary to start reading these guides also for CentOS .. It is the one we use at our university
Greetings José Gil !. It would be positive to know in advance, what topics are of interest to you? To see if we have not included any of them even in the series of articles that we are already delivering. Thanks for comment.
excellent initiative, not everything is ubuntu or debian, I think it's great, we hope more deliveries and what you can help with with pleasure.
Thanks for the excellent initiative, @josspcr.
On September 15, 1993, Debian release 0.01 was released. On November 3, 1994, Red Hat released its first release of the then Red Hat Linux, discontinued in 2003 in favor of RHEL. On September 17, 1993, Slackware released its first release. These distributions are considered as the "Oldest or Parents" of the current Linux universe. Ubuntu is descended from Debian, and SUSE from Slackware. CentOS is a binary clone of RHEL.
I think that with the proposal to include CentOS and OpenSUSE, we will write about the best offspring of two of the "Three Grandparents". We also won't stop dealing with Grandpa Debian directly. 😉
Hi… Does CentOS come with Gnome version 2? Because I have installed it and the interfaces it offers are not very modern, I assume that it is because it is focused on the servers and not on the end user, but I do not know if it really is.
: )
Hi… Does CentOS come with Gnome version 2? KDE 4.14? Because I have installed it and the interfaces it offers are not very modern, I assume that it is because it is focused on the servers and not on the end user, but I do not know if it really is.
That's why. What's more, it probably doesn't have wireless card drivers, the video card doesn't work 100%, or you have an end-user issue.
It is because CentOS is focused purely on servers.
Hello Alejandro. With CentOS and Red Hat Enterprise Linux, it is much the same as with Debian. They are operating systems focused on being used in servers and workstations or "Work Station". They are known for their stability, security and reliability. As a general rule, their cores or kernels are not the last, but the most stable ones tested in a production environment.
During the installation of CentOS, you can choose between the GNOME 3.14 and KDE 4.10.5 desktops. GNOME is the one we suggest, as Red Hat Inc. is responsible for sponsoring its development.
Hi Gonzalo. Thanks for comment. I have a hard time speaking in absolute terms in the Linux universe. If you have followed my articles you will notice that lately in most cases "I suggest" and very few times "I recommend". What CentOS is purely Server-oriented, it's a bold claim. I know a couple of network administrators who use CentOS on their PCs, and don't even play around telling them to switch to Fedora or OpenSuSE. On the other hand, there is a slight conceptual difference between PC and Work Station. The translation of the second indicates "Work Station." I myself worked for more than a year on a server with 512 megabytes of RAM and 8 megabytes of video RAM, nothing more, and I did not give up my graphical environment, despite the fact that that server worked -and still works- as a file server through Samba. I suggest you try and install a CentOS like Desktop. Go and improve opinion about it. 😉
I forgot to add that one of the options offered by the CentOS installer during the installation process is precisely that of a "GNOME Desktop". If it were purely Servant-oriented ... Let each one draw their own conclusions through practice, which is one of the best criteria of truth.
And could a version of Centos be installed for personal use on a laptop? I think about it throughout the maintenance cycles that this distribution has. Now it will not behave in daily utilities. Has anyone used Centos personally?
really a good post, another one of excellent quality, do not stop writing
Hi, and greetings from Holguin ... (sorry for the lack of Spanish symbols and accents, keyboard in German)
I found the article by chance and it seemed very good. Very good work and I hope that free technologies, especially Linux distros take a greater role in regard to the state and begin to take up spaces in the homes of our countrymen who not only use the pc to play DOTA, hahaha ... I in in my case I have 3 PCs (a Macbook and 2 desktop) at home, and all 3 have linux systems on them (apart from MacOS X, unix base on the laptop), two have Mint 18 Mate (1 desktop and the laptop as a system aside) and the other one that I use as a server has Debian 8.5 because I have it as an all-in-one (UPnP server, OwnCloud, Router, DNS, DHCP and HTPC with Kodi) ... every time someone comes to my new house they are speechless with the functionalities that I have and many have already migrated, although it is worth noting that all with dualboot together with Windows ...
Anyway, what I hope is that everyone in our country can become "free" one day, that day of the Final Judgment where they will have to pay licenses and updates for not migrating on time ... I repeat the most sincere greetings from the city of Los Angeles. parks, Jose ...
Linux Mint 18 Mate. MintOS by theme hdslayer1990@nauta.cu
I had not answered your comment properly because I did not receive it via e-mail… it happened a little at the beginning, but not anymore… thank you very much for your opinions, Hdslayer
A few notes about CentOS:
CentOS (Community ENTerprise Operating System) is better known in the world of Servers. Its Desktop version is not that popular although it continues to improve its visual appearance year after year.
It is the best and most used Linux distribution for Servers due to its robustness and stability; In addition, being 100% binary compatible with Red Hat Enterprise Linux, it makes it the number 1 alternative, to RHEL, for VPS (Virtual Private Servers) vendors in the Cloud.
Of course what has just been stated is perfectly refutable according to the point of view of each "sysadmin".
Finally, according to the "10 Top Most Popular Linux Distributions of 2016" it ranks 9.
Greetings Wong: I agree 100% with you. In fact, the first paragraph of the article reflects what you say regarding our country. However. Debian holds 3rd place on distrowatch.com. 😉
