CentOS which stands for Community Enterprise Operating System is one of the most widely used Linux distribution available for free. It powers many web servers across the globe. It is based on Red Hat Enterprise Linux (RHEL). But please note that even though it is based on RedHat Linux, it is not RedHat Linux. It is an OS with its own identity and one of the most widely used OS in the world today. If you wish to run any of your applications on cloud such as Amazon AWS or Microsoft Azure etc., CentOS will be one of the OS you can choose from.
Since these days most of the personal computers are powerful enough to run virtual machines, I recommend people to use a virtual machine to experiment with various other operating systems available in the market today. This avoids the need to clean install the new OS which is quite tedious and locks one down with one preference of the OS.
In this post, I wish to show you how to install CentOS on VMware workstation. To install VMware Workstation on windows please follow this post.
This is the link to the official CentOS website. You can download the installation media from here. There are official documentations here you can refer to.
CentOS Installation media download options:
On the official website home page, to get the installation media, you have to click Get CentOS Now. Here you will see 2 download options which are listed below:
- CentOS Linux DVD ISO– Download size around 7.7 GB. This is the desktop version with GUI and contains the standard linux packages which comes pre configured with any desktop version of the linux OS such as C, pyhon, ruby, php etc. Install this if you wish to work on CentOS for software development in desktop mode or for learning purposes. For additional packages not available by default, you will have to install them yourself using the package manager. I use this release for installation and personal work
- CentOS Stream DVD ISO– Download size around 7 GB. CentOS Stream is a rolling-release Linux distribution that exists as a midstream between the upstream development in Fedora Linux and the downstream development for Red Hat Enterprise Linux (RHEL). In practice, CentOS Stream will contain the code being developed for the next minor RHEL release. If you want to work with experimental features for future RHEL releases, you can use this release. I hardly use this release
