Once you have finished providing the basic information (language, keyboard, date and time), click on the installation source to confirm the ISO image that we have linked in step 2. It requires the basic information to set up the server:įrom the first opening screen, select the language that you would like to use during the installation process for example, English (United States). It will take time to load the packages, and you will see the opening screen of the server. Select “ Install CentOS Linux 8” and proceed. Click on the setting – storage – empty and browse the ISO image.Įnable the network adapter so that it can use the internet to download the required packages.Īfter that, the following screen is presented. The ISO image of the downloaded CentOS has to be linked to the newly created virtual machine. Every step is presented below for a better understanding. The 8GB space is insufficient, then set up at least 15 GB to start with (image 5 below), select and then finish the setup. Select the dynamically allocated, make sure that your hard drive has enough free space.
Fixed size of the disk is not recommended in any scenario because you will be downloading many packages to run various applications. Next, create the virtual disk (VDI) and move to the next screen. Allocate at least 1024MB you can allocate more if you have enough memory.
In the next window, allocate the memory size. Click on the new to set up the new VM, select the Linux and then Red Hat, since CentOS is the clone of Red Hat and uses a similar architecture. The 64-bit architecture has been used for this demonstration, so download the software accordingly. In this article, we will discuss the core architecture, how it is different from others and how to install and configure it on the VirtualBox (demonstration).ĭownload the appropriate version of both the packages. However, it has been clearly adopted by a large number of community members, so it must have some weight over others. The CentOS clearly stands out amongst the others. According to the report concluded by SolveDNS, CentOS, RedHat, Ubuntu and Debian are the top, and Fedora follows them. Let’s break it down into the actual OS, because there are many operating systems based on Unix are available in the market.
Another clear signal is the new release of Microsoft Defender for Linux environments. For instance, Microsoft is promising to dramatically improve its Windows Subsystem for Linux (WSL) with GUI app support and GPU hardware acceleration. To fight this trend, Microsoft have done fast and close proximity with Unix systems in the last years. According to data from W3techs, in 2017 Unix servers were used by 66.5% of all the websites, and 33.5% are using Windows OS. In the last few years, the market changed, but the Unix advantage is very clear: Unix-based operating systems are ruling the webserver OS market.
