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.
CentOS Official Website
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 3 download options which are listed below:
- DVD ISO– Download size around 4 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 availabe by default, you will have to install them yourself using the package manager.
- Everything ISO– Download size around 7 GB. This contains all of CentOS including what is available in DVD ISO. This also has a GUI. If you have bandwidth to download 7 GB, I would recommend this.
- Minimal ISO– Download size around 600 MB. This contains the core CentOS with out GUI. That is, you will have to work on command line interface. If you wish to run a server, this is recommended as you can selectively install any package you want such as php, apache etc. This helps to keep the OS small and robust. The interface is the same as in any CentOS VPS servers available in the market. If you wish to learn how to work on cloud servers running CentOS, this is what you should use. Normally you access your cloud server using SSH client such as putty. Once you have the access, it is same as working on CentOS in CLI (Command Line Interface) mode.
When I was downloading the ISO file directly, I faced broken download problem. That is, download stoped in the middle multiple times. I would recommend you to use torrent to download the installation media. You will see the torrent option on the download page.
