1 Introduction

In this lab, participants will download Oracle Linux 6.3 software from the Oracle

Software Delivery Cloud and then learn how to do a simple installation of Oracle

Linux 6.3 inside the VirtualBox application. After installing Oracle Linux 6.3,

participants will update the base install with latest packages and updates. This lab

will also include steps to install VirtualBox Guest Additions software on Oracle Linux

6.3.

Upon completion of this lab, participants will have learned how to obtain Oracle

Linux software, do a simple installation of Oracle Linux 6.3 and then update the

installed software with latest packages and patches.

2 Overview

There are four significant steps involved to complete this lab:

A. Create a Virtual Machine in VirtualBox Application

B. Install Oracle Linux 6.3 in the Virtual Machine

C. Update Oracle Linux 6.3 with latest patches and updates

D. Install VirtualBox Guest Additions Software

We will begin by downloading the Oracle Linux operating system software. Next we

will create a Virtual Machine and configure its settings. This Virtual Machine

running inside VirtualBox Application will be used to install Oracle Linux 6.3

operating system. We will do a simple installation of Oracle Linux 6.3 operating

system in this lab. After installing Oracle Linux 6.3, we will use the Oracle Public

Yum Server to update the image with latest packages and updates. Finally, we will

install VirtualBox Guest Additions Software.

3 Pre-requisites

This lab requires the use of the following elements:

A current 64 bit laptop with at least 2GB RAM and 20GB free disk space

Operating system: A 64-bit version of Microsoft Windows, Mac OS X, Linuxor Solaris. Alternatively, a 32-bit host OS installed on a 64-bit CPU with VT-

x/AMD-V enabled in the BIOS.

Oracle VirtualBox Software (4.2.x with Extension Pack 4.2) installed

Oracle Linux 6u3 64 bit ISO image file or DVD media (Part # V33411-01)

The following assumptions have been made regarding the environment where this

lab is being performed:

1. Network connectivity to the Internet is required

2. Participants should have downloaded Oracle Linux 6.3 x64 bit ISO image

from the Oracle Software Delivery Cloud.

4 Pre-requisites

The Software Environment used to capture screen shots captured/shown in this lab

is shown below:

Windows 7 Host Operating System

VirtualBox Version 4.2.6

Installation of Oracle Linux 6.3 (64 bit version)

The product versions and screenshots shown in this document may slightly differ

depending on the product versions you use when you perform the lab.

4.1 Oracle VirtualBox Hypervisor Software basics

Your host system should already have Oracle VirtualBox hypervisor software

installed and ready to use. If not, the latest version can be provided by your

instructor or you can download it from Oracle.com using the link below.

Download VirtualBox

VirtualBox Notes:

VirtualBox Installation Documentation

Installing VirtualBox Video

VirtualBox mouse capture can sometimes be awkward in the way it handles

mouse interaction between VirtualBox and your OS. Use the right controlkey on your keyboard to return mouse control back to your default

environment. You can change this in VirtualBox preferences. Once the Oracle

Linux OS installation is complete, we will install VirtualBox Guest Additions

software.

VirtualBox Guest Additions Software will make life much easier by providing

closer integration between host and guest and improving the interactive

performance of guest systems. The Guest Additions are designed to be

installed inside a virtual machine after the guest operating system has been

installed and this software helps improve mouse pointer integration between

the guest and host operating systems.

4.2 Download Oracle Linux 6.3 ISO image file

You will need the ISO image for Oracle Linux 6.3 x64 bit version to do this lab. You

should already have downloaded the ISO image if you completed the pre-requisites

of this training. If you have already downloaded the ISO image on your laptop/host

system, skip this section and proceed to Section 5.1. In case you need to download

the ISO image file, you can download the ISO image file and save it on the disk drive

of your laptop. You can use the location provided below to download the ISO file.

Download Oracle Linux 6.3 x86 64 bit ISO Image

OL 6 - Lab 01

Select Oracle Linux as Product Pack and Platform as x86 64 bit:

Select Oracle Linux Release 6 Update 3 Media Pack for X86 (64 bit):

Download Oracle Linux Release 6 Update 3 for x86_64 (64 Bit) ISO image file:

Part # V33411-01Save the ISO image file on the disk drive of your laptop as ‘V33411-01.iso’ image file.







OL 6 - Lab 01

NOTE for 32 bit Version:

If you do not have a 64 bit laptop or system, you can use the 32 bit Oracle Linux 6.3

ISO. The part number for Oracle Linux Release 6 Update 3 for x86 (32 Bit) ISO is

V33415-01. This ISO file can be downloaded from Oracle Software Delivery Cloud.

Important: This Oracle Linux 6 boot camp training and all labs for this training

were created for 64 bit Operating System. If you use the 32-bit Oracle Linux 6

Operating System then some of the labs cannot be completed. These are labs for

which only 64 bit version of the software is available like the DTrace lab. Hence it isstrongly recommended to use 64 bit setups for this Oracle Linux 6 boot camp

training.

Important Note for 32 bit Version Installation:

If you are using 32 bit ISO of Oracle Linux 6.3 and installing inside VirtualBox then

you may encounter an issue after the installation. After the installation when the

FirstBoot tool runs if you experience a problem with VirtualBox application (like a

crash of VirtualBox) then you should boot your Oracle Linux host system in single

user mode and disable the FirstBoot application by creating the following file. Boot

in single user mode and create the ‘firstboot’ file as shown below:

# echo "RUN_FIRSTBOOT=NO" > /etc/sysconfig/firstboot

After creating this file, you can normally boot into init runlevel 5. Use this

workaround only if you run into issues installing the 32 bit Operating System in

VirtualBox application.

We have now completed Oracle Linux 6.3 installation and have a working system

that will be used for doing all the training labs. If you ran into issues or could not get

the system to install properly on your laptop, you may check with your instructor to

see if a pre-installed Oracle Linux 6.3 VM image works on your system.

NOTE: It is recommended to take a snapshot of your system at this time using

the VirtualBox snapshot capability. This will be your clean vanilla installsnapshot. Shutdown the system and create a snapshot in VirtualBox.

5.4 Updating your Oracle Linux 6.3 Server with latest patches and updates

Like any other operating system, patches and updates are released regularly for

Oracle Linux. In this lab, we will update the base image with the latest patches and

updates using the Oracle Public Yum Server. We will log out as ‘student1’ user and

log back in as ‘root’ user to perform this lab.

Note: The versions of products/patches/updates may differ from what is shown in

the screenshots shown below. The versions will depend on what is the latest version

available at the time you perform this lab. But the steps/commands used below

should be applicable to later versions of Oracle Linux 6.3 release.

Note: This lab requires internet connectivity.











OL 6 - Lab 01

When you first login as ‘root’ user, on a freshly installed Oracle Linux system, you

should expect to see a warning message similar to what is shown below. Read thismessage, acknowledge the warning and then click ‘Close’ to proceed.







OL 6 - Lab 01

After logging in as ‘root ’ user, open a Terminal window and perform the following

steps:

[root@examplehost /]# cd /etc/yum.repos.d/[root@examplehost yum.repos.d]#

Check to see if there is a ‘/etc/yum.repos.d/public-yum-ol6.repo’ file already

present. If one is present, move it out of this directory if you wish to preserve the

original file or delete this file.

[root@examplehost yum.repos.d]# rm public-yum-ol6.reporm: remove regular file `public-yum-ol6.repo'? y[root@examplehost yum.repos.d]#

Note: Make sure you have enabled your network connection and you have internet

connectivity. You may have to enable your network connection if it is inactive. The

network connection can be enabled by either using the GUI or the ‘ifup’ command asshown in the screenshot below.

Alternat ively, from the UI, click the ‘System eth0’ interface from the Network icon onthe top right side.







OL 6 - Lab 01

To activate the network interface upon every reboot of the system, you can right

click the Network icon and then click ‘Edit Connections’ option.

In the ‘Network Connections’ window, select the network interface ‘System eth0’

and then click the ‘Edit’ button.

Click on ‘Connect automatically’ and then click the ‘Apply’ button. Next time you

reboot your system it will automatically activate the network interface while

booting.







OL 6 - Lab 01

Also, set the proxy server if needed under System -> Preferences -> Network

Proxy.

Proxy Server Configuration (if required):

Network Proxy configuration can be found under System -> Preferences ->

Network Proxy menu option as shown below.

Depending on your Network environment, you can define a Manual Proxy

configuration or automatic proxy configuration settings. Check with your network

administrator to find out the proxy server information and enter it in the Network

Proxy Preferences window.







OL 6 - Lab 01

Verify internet connectivity by opening a web page in your browser to make sure

you can access the internet.

We will download new repository configuration file from the Oracle Public Yum

Server using the ‘wget http://public-yum.oracle.com/public-yum-ol6.repo’

command as shown below. This is because the repository configuration file gets

updated when new releases or channels are introduced.

[root@examplehost yum.repos.d]# wget http://public-yum.oracle.com/public-yum-ol6.repo

--2013-01-09 16:08:28-- http://public-yum.oracle.com/public-yum-ol6.repoResolving public-yum.oracle.com... 141.146.44.34Connecting to public-yum.oracle.com|141.146.44.34|:80...connected.HTTP request sent, awaiting response... 200 OK

http://public-yum.oracle.com/public-yum-ol6.repo












OL 6 - Lab 01

Edit the repository configuration file (‘public-yum-ol6.repo’) and review the

contents of this file. Look at all the channels available. Enable following two

channels in this repository configuration file:

ol6_latest

ol6_UEK_latest

These 2 channels should be enabled by default but if you need to enable them set

“enabled=1” as shown below. Edit the repo configuration file using ‘vi’ or any other

editor that you are familiar with.







OL 6 - Lab 01

[root@examplehost yum.repos.d]# vi public-yum-ol6.repo

[ol6_latest]name=Oracle Linux $releasever Latest ($basearch)baseurl=http://public-

yum.oracle.com/repo/OracleLinux/OL6/latest/$basearch/gpgkey=http://public-yum.oracle.com/RPM-GPG-KEY-oracle-ol6gpgcheck=1enabled=1

[ol6_UEK_latest]name=Latest Unbreakable Enterprise Kernel for Oracle Linux$releasever ($basearch)baseurl=http://public-yum.oracle.com/repo/OracleLinux/OL6/UEK/latest/$basearch/gpgkey=http://public-yum.oracle.com/RPM-GPG-KEY-oracle-ol6gpgcheck=1enabled=1

Note: At the time of creation of this lab, Oracle Linux 6.3 was the latest release. If

you are doing this lab at a time when a newer release like Oracle Linux 6.4 is

available, the ol6_latest channel will pick up updates/patches available for the 6.4

release and upgrade your system to Oracle Linux 6.4.







OL 6 - Lab 01

Once you have verified and enabled both the channels in the Repository

configuration file, you are ready to update your system with latest patches and

packages.

As was mentioned earlier, to update the packages, you need to ensure that you have

internet connectivity. We will connect to the Oracle Public Yum Server to download

the latest updates and patches available for Oracle Linux 6.3 release. You may also

need to configure your Network proxy server settings inside the Oracle Linux

system to be able to connect to the internet.

Once you have confirmed network connectivity to internet is available, you can run

the ‘yum update’ command to update Oracle Linux 6.3 base packages and install the

latest patches. See the commands and screen shots below.

root@examplehost yum.repos.d]# yum update

Again, remember that the ol6_latest channel is enabled and running ‘yum update’

can even upgrade your system to the latest dot release like Oracle Linux 6.4 release

if that release is available at the time of doing this lab. When these screenshots

below were captured, the latest release was 6.3 and 6.4 had not been released yet.

Note: If you run ‘yum -y update’ and get a message about another copy of ‘yum’ is

running, check using ‘ps –ef’ to find the process id and kill it if needed and then tryrunning the command again. This can happen if PackageKit application is checking

for updates at the same time as you run the ‘yum’ command.











OL 6 - Lab 01

Click ‘y’ to begin downloading the available updates and packages. Depending on the

number of updates and patches and your internet speed, this step may take a few

minutes. Click ‘N’ if you have a slow internet connection and wish to perform this

lab later.







OL 6 - Lab 01

Click ‘y’ to import the GPG key. The installation of updates will now start and you

should expect to see messages similar to what is shown in the screenshot below.







OL 6 - Lab 01

Run the “uname –a” command after the patches and updates have been installed.Check the output of the ‘uname’ command and note the kernel version. In the above

screenshot, we can see the system is running UEK Kernel Version 2.6.39-200.24.1.

This version corresponds to UEK Release 2 and was the initial version of our

System. It continues to show the initial version because that is the kernel version

that we had booted into before applying the patches.







OL 6 - Lab 01

Since the patches included a newer kernel version, it is recommended to reboot the

server and to use the new kernel version that was installed. Reboot the system after

installing all the patches and updates.

To reboot the system, click the System->Shutdown menu option or run the ‘reboot ’

command line program. Once the system has rebooted you can log back in andverify using the ‘uname -a’ command that the new kernel is applied and running. In

the screenshot below, you can see the new kernel version. This version may differ

depending on when you are doing the install and what is the latest kernel version

available at that time. You can also check the release (-r option) and the distribution

(-d option) information using the ‘lsb_release’ command as shown below.

5.5 Install VirtualBox Guest Additions Software

VirtualBox Guest Additions will make your life much easier by providing closer

integration between host and guest and improving the interactive performance of

guest systems. The Guest Additions are designed to be installed inside a virtual

machine after the guest operating system has been installed. They consist of device

drivers and system applications that optimize the guest operating system for better

performance and usability. Please see the section called “Supported guest operatingsystems” for details on what guest operating systems are fully supported with Guest

Additions by VirtualBox.

The VirtualBox Guest Additions for all supported guest operating systems are provided

as a single CD-ROM image file which is called VBoxGuestAdditions.iso. This imagefile is located in the installation directory of VirtualBox. To install the Guest Additionsfor a particular VM, you mount this ISO file in your VM as a virtual CD-ROM and install

from there.

https://www.virtualbox.org/manual/ch03.html#guestossupport












OL 6 - Lab 01

The Guest Additions offer some of the following features:

Improved Mouse pointer integration

Shared folders

Better video support

Click OK button to auto-run the installer for Guest Additions software. You will see adialog window like following:







OL 6 - Lab 01

Click ‘Run’ to begin running the install script for Guest Additions. You will see a

VirtualBox Guest Additions installation window with install messages. If you see afailure during install, it is most likely due to missing gcc utility or mismatch of kernel

headers/devel package. You may expect to see a screen shot similar to what is

shown below for such failures:







OL 6 - Lab 01

As you can see from the messages above, it complains about missing ‘gcc’ utility and

missing ‘kernel-uek-devel’ package. Installing ‘gcc’ automatically should install the

kernel. Let’s install the ‘gcc’ package and then try running the Guest Additions

installer again.

To install ‘gcc’ package, simply run the “yum install gcc” command and it will resolveall dependencies and prompt you to install all the dependent packages as well as the

‘gcc’ utility. See screenshot below.

Click ‘y’ to install all the packages when prompted:







OL 6 - Lab 01

You can see that it installs the kernel headers package as part of ‘gcc’ installation.







OL 6 - Lab 01

Now that ‘gcc’ is installed, let’s run the Guest Additions installer again. To run the

installer, double click the VirtualBox Guest Additions CD on the desktop and click

the “autorun.sh” script.







OL 6 - Lab 01

Run the ‘autorun.sh’ script from the Guest Additions CD by opening the CD in File

Manager application.







OL 6 - Lab 01

Click on ‘Run in Terminal’ option when it prompts you to run the autorun.sh script as shown above. The installer will run and you should see Guest Additions software

get installed as shown below.







OL 6 - Lab 01

You can confirm and see that everything installed OK. Close this VirtualBox Guest

Addition install window. This completes the installation of Guest Additions software

and now you should see better mouse pointer integration between the host and

guest operating systems.

5.6 Snapshot the Virtual Machine

We have our Virtual Machine running Oracle Linux 6.3 with latest patches and also

the Guest Additions software installed. It is a good idea to capture a snapshot of this

Virtual Machine before proceeding with any other labs or any other exercises. We

will use the VirtualBox snapshot feature to create a snapshot of this image.

You should shutdown the Oracle Linux System and then create a snapshot.

Shutdown the Oracle Linux 6 system using the System->Shutdown menu option.

To create a snapshot, from the VirtualBox Application, Click the Snapshots option

on the top right side. See screenshot below.







OL 6 - Lab 01

Click the Camera icon to create a snapshot as shown below:







OL 6 - Lab 01

Clicking the Snapshot icon will display the following window:

Give a logical name for the snapshot and enter a short description to remember the

state of the system when this snapshot was created. See example above. Once thesnapshot is created you will see the following window.




We now have a snapshot created for our Oracle Linux 6 system. If you ever need to

restore back to this clean image you can use this snapshot and boot into it.

6 Lab Summary

In this lab exercise, you learned how to create a virtual machine inside VirtualBox

application and then install Oracle Linux 6.3 operating system in that virtual

machine. You also learned how to update the base release of Oracle Linux 6.3 with

the latest patches and updates from the Oracle Public Yum Server.
