Welcome to Linux tutorial series. In our first tutorial I will teach you how to install Red Hat Enterprise Linux 7 .

This is basic installation tutorial and will be using virtual machine to install operating system on it using Anaconda installation program. Before starting Redhat 7 installation first we will look at requirements

Requirements:

you will need active Red Hat subscription to download RHEL7.1  ISO image from Red Hat Customer Portal.

  1. RHEL 7.1 Binary DVD ISO image

RHEL 7.1 can be installed on variety of systems  Intel 64,AMD64, IBM Power,IBM System Z etc. But in this tutorial we will create a virtual machine (VM) using Open Virtual Box and then will deploy RHEL 7.1 OS .

Download DVD Binary ISO image from Red Hat portal

2. Download oracle virtual box from https://www.virtualbox.org/

A) Installation of Virtual Box,

On windows after downloading oracle virtual box double click on download exe file . Follow installation wizard or for more information go to https://www.virtualbox.org/manual/ch02.html#idp91873440

B) Create virtual Machine

After installing oracle virtual box we will now create a virtual machine (VM) on which then we will install RHEL 7.1

To create new VM in Virtual Box you can either Right click on Machine–> New as shown in screenshot below or you can click on New button on tool bar of Virtual box

VM1

Specify name and Type then click Next

VM2

Specify version and click Next

Select VDI as hard drive type as we are using Virtual Box for this tutorial. In real life type can be anything from the list depending upon virtualization tool you are using.Click Next

VM7

Select Dynamically allocated option. Click Next

V8

Create Disk size of 25 GB and keep default settings for file location

After creating VM now we will install RHEL 7.1 (Operating System/OS)

We will power on VM but we need start Anaconda (Linux installation utility from virtual CD ROM). To do this

Highlight VM . Right Click and select setting as shown in below screenshot. You can also highlight VM and select setting option as shown in next screenshot following below one

We will select server with GUI. For now we need GUI (Graphical User Interface) of Linux which will help in learning linux quickly for beginners

25

In this step we will select destination where we will install Linux. Click on Installation destination

26

As we created only one virtual hard disk. We will install on that disk. You will notice it is already selected automatically

27

Kdump is optional. When system crashes information from memory at crash time are stored in log files. But Linux system rarely crashes so we will not enable it.

28

Disable Kdump by unchecking box as shown in screenshot below and then click done

kdump

Next screen is for network and hostname settings.You will see network is disabled.

networkoff

Connect to network by sliding the bar

networkconnect

you can manually configure network by clicking on configure button. But we will leave this at moment.

At bottom of network screen you can set hostname. We will name VM fully qualified domain name. As we do not have registered domain. So we will name rhel7.example.com (example.com domain)

hostname

Once you are happy with installation options you have chosen earlier . You can click on Begin Installation

34

Installation of Linux will start.While system installs Linux you will be provided choices to create  a) root password and b)create non root user(which is optional)

35

First we will create root password. I will set password for training purpose. You will see warning that password is too week at bottom of screen but you can ignore it. After setting password click Done twice

rootpassword

38

Now click on user creation option. We will not do most of linux operation as root user because root We will make this user as non administrator . We will try to do most of operation using this user whenever we need to perform administrative we can switch to root user. Later we will also create user with Administrative privileges.

nonrootuser

Enter user details including password. Click Done

Now wait until systems finish installation

After Linux installation has finished. Click Reboot

55

On Desktop right click and select Open in Terminal

shellprompt

Above terminal is default shell for linux. you can see ali is user id and hostname is rhe7 (ali@rhel7) and dollar sign $ in prompt. This means this user is non Administrator user. to switch to root user use below command

switch-to-poweruser

I hope you have enjoyed and learnt basic installation of Red Hat Linux 7. In next tutorials most of time we will be using terminal /shell prompt.Thank you for visiting my tutorial page
