Full Linux Tutorial: Go from Beginner to Advanced with RedHat Linux, CentOS, and Kali Linux!
Linux was an OS originally targeted for developers and those interested in coding. It has proven quite useful in those roles. Many distributions of the OS such as CentOS, Kali Linux, and RedHat Linux have been developed. Here is what you should know about them.
1. Read the official documentation
By perusing through the Documentation that comes with all three of them, you will get to understand basic concepts. For instance, you will understand how an OS can run from a USB, how you can run two OS at the same time on your computer, each OS version comes with documentation that clearly explains all of these concepts.
2. Make Use of the Many Editorials on YouTube
If you have a hard time using any of them, go to YouTube. Some are less than a decade old. However, those who have tinkered with them have ensured that there are videos available on YouTube. However, you must be careful to check the versions of the tutorials you watch. For instance, be careful not to use Kali 1.0 while you are trying to install Kali 2.0.
Always check the version in the description before loading a video to avoid time wastage. Additionally, if you are trying to run two OS on the same computer, ensure that you have the right video for the version of the existing OS. For instance, do not use a tutorial for Windows 8 while you are working with Windows 10. If you fail the first time, do not be discouraged. Installing an OS is not easy for anyone.
3. Ensure that you Have Some Knowledge on Linux
All of these OS are built on Linux. That means that most of the concepts used on Linux will apply to them. Thus, a basic knowledge of Linux OS will prove quite useful.
4. Do Not Install Tools Manually in FHS Defined Directories with Kali
If you plan to use Kali long term, do not use manual installs in FHS defined directories. It will cause conflicts in the apt package manager. However, if Kali is for a one-off engagement, you can do this without fear of anything going wrong.
5. Ensure that You Have a RedHat Subscription
A valid RedHat subscription gives you the ability to perform a full system update. It will also give you access to RedHat system repositories. Besides that, you will benefit from the expertise of experienced software engineers.
6. Configure the Static IP address
When you install RedHat, you need to ensure that the Static IP address is configured. To do that; you will need to use ip command, which replaced the ifconfig command.
7. Understand the Command Line Interface
If you are serious about these Os, you have to get used to the command line interface of Linux. Although it is comparable to the command prompt in Windows, it is more efficient. It will make your experience quite enjoyable if you understand how to use Linux commands.
8. Enable or Disable the Sidebar Option in Kali
Some people find it to be a bother. It is especially so in smaller resolution. If it is a bother to you, you can view the numerous video tutorials on YouTube on how to disable it.
9. Ensure You understand How to Use a Virtualized Environment
As you begin to expand your skills in the use of these OSs, you will have to experiment to be good at them. However, you may not be confident enough to try your skills in the real world. In such a case, you will need to understand how to use virtualization software. You can use many different virtualization software; ensure that you choose software with which you are fully conversant.
10. You Can Always Add a Non-Root User
Some people may not be comfortable performing some functions when the user is root. It is especially so for those who use Kali. However, changing to a non-root user is quite easy. The simple command for doing this is to change the ‘muts’ username to yours.
11. You Can Disable USB Detect
It is one of the reasons you should use a Linux based OS. By doing so, you are able to avoid having to worry about people stealing data from your computer. It is especially so if you are a server administrator.
12. Ensure that You Always Have the Latest Version
Most Linux distributions are updated quite often. To ensure that you do not expose yourself to any security risks, ensure that you have the latest versions installed at all times. Besides that, it means you will be able to utilize the latest tools and features available for such OS.
