What do you like best?

The best thing about CentOs is that it has all the features of Red Hat EL but FREE.

It is fast, GUI is awesome and works great for Hosting your websites and databases.

Since it is Open source, if you encounter any issue in the system /server, you can just google the issue and I'm sure you will get all your answers. Review collected by and hosted on G2.com.

What do you dislike?

To be honest there is nothing to dislike as such. However, the recent move of Red hat to not provide any further patches is very disappointing. :( Review collected by and hosted on G2.com.

Recommendations to others considering the product:

If you are looking for using Linux then I would suggest you use CentOs and thank me later. :D Review collected by and hosted on G2.com.

What problems are you solving with the product? What benefits have you realized?

Mostly web hosting and mysql related issues.

As well Kernel and Operating system issues. Review collected by and hosted on G2.com.

What do you like best?

It is Linux/Unix, so with regards to configuration, if you can imagine it and you are a creative and skilled administrator, you can probably make it happen. Plus it is rock solid stable -- you get pretty much the same software packages as Red Hat Enterprise Linux, just a little behind on the timeliness of releases.

I use it at home and at work. I use it at home because I have five kids who click on anything and everything on the internet, and there's just not as much malware out there to affect a Linux operating system. Plus, it's just not as bloated as Windows, so performance is more efficient with the limited computing resources on my home computers.

Although I wouldn't run my mission-critical applications on it (since it is free), I feel safe running it in an enterprise environment for solutions such as firewalls, DNS, application front-end, etc. And you can purchase third-party support for it. It also has a great community of support on the internet, and software repositories are updated frequently and are reliable.

Finally, it runs on x86, so it works great in a virtualized environment (VMWare in our case) and can easily be deployed from a golden image over and over. Review collected by and hosted on G2.com.

What do you dislike?

Again, it is free and not "officially supported", so I wouldn't run my mission-critical databases and applications on it. Review collected by and hosted on G2.com.

What problems are you solving with the product? What benefits have you realized?

We use CentOS for enterprise-level needs, but not for mission-critical applications or databases (again, because it's not officially supported). We use it for firewalls, DNS, time servers, mail relays, reporting/monitoring, etc. Basically, things we need to be stable but not huge, dynamic workloads. Also, we have commercially-bought turnkey applications where the vendor requires and installs on CentOS. Review collected by and hosted on G2.com.

What do you like best?

So light weight and so secure. No bloatware and no extra ads. Just work to work. You will find all the necessary software for your daily use and that too in the simplest way possible.

Interface is very simple and clear. There is no fancy thing inside this OS. Just install it and start doing your work. Review collected by and hosted on G2.com.

What do you dislike?

Although interface is simple, I will urge CentOS team to make it little attractive. Make all the software available for this version. Make sure once people switch to CentOS, they won't go away. Review collected by and hosted on G2.com.

What problems are you solving with the product? What benefits have you realized?

I am a developer in my company and the software or website which we develop, are under great security and we are hereby use CentOS, highly secured and super fast. Optimization of RAM is so powerfull that we don't ever have any lagging issue.

Top of that CentOS doesn't have any bloatware and ads so we are rest assured that we are not exposed to any security.

Being a developer, we don't want to rely on any third party software to work on. CentOS provides all the necessary setup to feel like home. Review collected by and hosted on G2.com.

What do you like best?

The OS is quite abstract and lightweight which leads to installation of packages as per the need of user. This can help to get an isolated environment for your application running which can make developer life easy to have same environment everywhere. Review collected by and hosted on G2.com.

What do you dislike?

Sometimes finding packages which are needed by the application can be painful and hence leads to hit and trial. In that case, leading to a different OS is not the solution which can slow down th development speed. Review collected by and hosted on G2.com.

What problems are you solving with the product? What benefits have you realized?

Containerised application operating systems which helps to isolate the application in a dedicated environment. This is helping to avoid dependencies issue on production servers and parallel processing with different OS running at the same time. Review collected by and hosted on G2.com.

What do you like best?

CentOS commands are very user friendly and we can remember them easily. Its similar to RHEL and the commands are almost same. Beginners can start learning with centos and get an experience with command line. Since it is open source anyone can download and use it for free. The centos community is very much helpful and knowledgeable. Review collected by and hosted on G2.com.

What do you dislike?

The image is not light weight due to so many tools and packages. The GUI part is not user friendly. Apart from these there are no major drawbacks of centos. Review collected by and hosted on G2.com.

Recommendations to others considering the product:

I would strongly recommend to use centos as its similar to rhel and open source. You get all the features of rhel and the support you required from centos community. Review collected by and hosted on G2.com.

What problems are you solving with the product? What benefits have you realized?

I work regularly with centos, i used to face network issues and application related issues. sometimes we also solve issues related to storage. Review collected by and hosted on G2.com.

What do you like best?

The speed of command execution is really quick even simple operations like copy paste are much quicker than windows. Review collected by and hosted on G2.com.

What do you dislike?

A bit more user friendly interface would be appreciated since the graphical interface is a little tough to get used to. Review collected by and hosted on G2.com.

Recommendations to others considering the product:

I recommend using this if you are looking for a light weight solution to windows operating systems, and also since this is a free to use version the help community on the several forums can always help out with any issues that you face, also most of the issues that you would face as a new user would have already been resolved on the forum earlier so it would be much easier to access any information that is available on these forums.

Also once you get used to the terminal for running commands it will easily show you how much faster and quicker your commands get executed. Review collected by and hosted on G2.com.

What problems are you solving with the product? What benefits have you realized?

Coding and application development are being done using centOS, benefits include time saving and also requires less effort. Review collected by and hosted on G2.com.

What do you like best?

Simple interface and high level of security. Very easy to connect with server and work on server. Review collected by and hosted on G2.com.

What do you dislike?

Lack of a lot of application. As windows has all kind of software to work with, sometimes CentOS lacks many software. Review collected by and hosted on G2.com.

What problems are you solving with the product? What benefits have you realized?

As I am a developer, I have to work with different types of languages to form a software. So I have to work on servers and have to edit the file on servers so it's very easy to connect. My files are very safe and security is high class. And there is no vulnerability. Review collected by and hosted on G2.com.

What do you like best?

I like best that you can simply use CentOs to create smart software appliances.

In use with GUI it is a nice alternative to windows. Review collected by and hosted on G2.com.

What do you dislike?

It is hard to learn and need high skill to configure.

Besides that you will need some programming skills if you use only the cli variant. Review collected by and hosted on G2.com.

Recommendations to others considering the product:

try to find use cases what you really need and see if it fits on centos. IT is a light weight OS so you keep resources for the application Review collected by and hosted on G2.com.

What problems are you solving with the product? What benefits have you realized?

Creating an environment where users can upload content from outside the organization.

We use it mainly for our nutanix nodes, these are installed with Centos and on top off that it hosts a hypervisor Review collected by and hosted on G2.com.

What do you like best?

It's almost the same as RHEL, provides most of the enterprise features. It still adopts older standards, while implementing the new ones, so someone who started earlier (like the '80) still can use his/her knowledge to operate this system. Obviously, it's better to learn the new standards, but backwards compatibility is an important factor, it does help to veteran users.

You can get training from RedHat (for RHEL), but you can use the knowledge on CentOS. RedHat trainings and certifications are highly valued, it's almost like an university degree (probably worth even more). Review collected by and hosted on G2.com.

What do you dislike?

Obviously, you don't have enterprise support (being a Community Enterprise OS), so you need the according knowledge for maintaining, or deploying this OS. People used to like yum as a package manager, my personal opinion is that apt is much better, has its flaws, but in general I tend to like it way more.

I tend to like the booting software of Debian systems more, anaconda and so are not that sophisticated as plymouth. These are little things, but in case of a broken boot, it does make your life hard when you need to fix it. Review collected by and hosted on G2.com.

Recommendations to others considering the product:

You will have to have the expertise to deploy and operate this OS. If you don't have it, use RHEL with support instead. Review collected by and hosted on G2.com.

What problems are you solving with the product? What benefits have you realized?

Having some old packages (old version of software) is usually comes up, solvable by adding additional yum repositories, or compiling newer versions of the packages.

Benefits are that is very similar to RHEL, so it has enterprise features (like connect to a Satellite), built in Ansible support, stable (but old) packages. Widely known in the industry, it's not hard to find people with this knowledge (but hard to find people with enough knowledge) Review collected by and hosted on G2.com.

Fastly it's free! That means they can download and use it for free without any limitations. For developers, that means they can access the code of the operating system at any time. CentOS gets things right in this department with excellent stability and security. Due to the focus being on running basic software variants, this OS has good speed even when compared with other Linux systems. As it is very close to RHEL, one can get the full flavor of RHEL, an enterprise Linux OS solution. Review collected by and hosted on G2.com.

What do you dislike?

Getting support is not as easy as the ubuntu. Review collected by and hosted on G2.com.

What problems are you solving with the product? What benefits have you realized?

Linux CentOS does a reasonably good job when it comes to essential apps. There are some obvious choices, such as Mozilla Firefox as the default web browser, LibreOffice for managing your office needs, and Rhythmbox as the default audio player.

The useful utilities include a clock, calculator, contact, as well as the primary text editor gEdit. Some of the other exciting choices are photo manager software called Shotwell, YouTube browser, and Virtualisation app.

CentOS even includes a DVD burner, and plenty of tools focused on communication. The default email app is Evolution, and the chosen chat client is Empathy. You can also use Ekiga Softphone as the VOIP client, and a webcam viewer software named Cheese. Review collected by and hosted on G2.com.

The lack of official help desk support from Red Hat. But when it comes to CentOS troubleshooting, Google is your friend. Review collected by and hosted on G2.com.

What problems are you solving with the product? What benefits have you realized?

This product allows me to deploy a large number of Linux systems globally without incurring a huge license fees. Unlike some Linux distributions, CentOS has a long support lifecycle.

Centos is a real alternative to the Official Redhat Release without the fee related to the license. Review collected by and hosted on G2.com.

What do you dislike?

The distribution will end during 2021 so it is not suggested to still implent this version on Linux in new Projects. Review collected by and hosted on G2.com.

What problems are you solving with the product? What benefits have you realized?

Before the notification of the end of the support in 2021, this distribution granted to me the possibility to have testing labs without the necessity to buy new subscription of RHEL so it saved me from additional costs on some project. The most important benefit after the cost saving is related to the possibility to have a RHEL compatible environment. Review collected by and hosted on G2.com.

What do you like best?

It's basically a free version of the highly successful RedHat Linux distribution. You can get almost same features for free, without paying thousands of the dollars for the technical support. If you're technically savy, and you do, as otherwise you won't use Linux, it's exactly what you need. If you need a support, the CentOS community is pretty active and knowledgeable, so you won't be in trouble. My decision to select that flavor of Linux for our needs was mostly informed by my previous experience with the RedHat systems . All the packages that I need were easy to find and install using the yum. Review collected by and hosted on G2.com.

What do you dislike?

It's mostly question of taste. You need to get used to the Redhat-specific tools, like yum package manager. You can get into some troubles configuring selinux as well. Due to the presense a lot of Redhat-specific stuff, the system is not lightweight on memory and processor resources. Review collected by and hosted on G2.com.

You could look at another distributions like Debian - they are also worth your consideration. Review collected by and hosted on G2.com.
