Set up RHCSA/RHCE Lab with CentOS

Overview of the Lab

Before we get started, let's take a look at an overview of our lab. For our lab we will have one physical system and three virtual machines:

Type Hostname IP Address
Physical host.example.com 192.168.1.50
Virtual server1.example.com 192.168.122.50
Virtual tester1.example.com 192.168.122.150
Virtual outsider1.example.org 192.168.100.100

  1. Download and Install CentOS on host. 

  2. Create an Apache Installation Server on host.

    1. yum install httpd
    2. chkconfig httpd on
    3. mount -o loop centos.iso /media
    4. mkdir /var/www/html/inst
    5. cp -ar /media/. /var/www/html/inst
    6. chcon -R --reference=/var/www/html /var/www/html/inst
    7. service httpd start
    8. open port 80 with system-config-firewall-tui from command line.

  3. Create a vsftpd Installation Server on host.

    1. yum install vsftpd
    2. chkconfig vsftpd on
    3. mount -o loop centos.iso /media
    4. mkdir /var/ftp/pub/inst
    5. cp -ar /media/. /var/ftp/pub/inst
    6. chcon -R -t public_content_t /var/ftp
    7. service vsftpd start
    8. open port 21 with system-config-firewall-tui from command line.

  4. Install and Configure KVM

    1. yum -y install qemu-kvm python-virstinst virt-manager virt-top virt-viewer libvirt libvirt-client
    2. mkdir -p /home/qemu/images
    3. usermod -d /home/qemu qemu
    4. chown -R qemu.qemu /home/qemu
    5. chcon --reference /var/lib/libvirt/images /home/qemu/images
    6. rmdir /var/lib/libvirt/images
    7. ln -s /home/qemu/images/ /var/lib/libvirt/images

  5. Set up a Network Adapter for outsider1

    1. Download outsider1.xml file.
    2. virsh net-define --file outsider1.xml

  6. Download the Following Kickstart Files

    1. Download ks_server1.cfg, ks_tester1.cfg, and ks_outsider1.cfg.
    2. Move the cfg files to /var/ftp/pub
    3. virt-install -n server1.example.com \
      --disk path=/var/lib/libvirt/images/server1.example.org.img,size=12 \
      --vcpus=2 -r 768 --os-type=linux --os-variant=rhel6 \
      --network network:default --vnc --accelerate \
      --location ftp://192.168.1.50/pub/inst \
      --extra-args "ks=ftp://192.168.1.50/pub/ks_server1.cfg"
    4. virt-install -n tester1.example.com \
      --disk path=/var/lib/libvirt/images/tester1.example.org.img,size=12 \
      --vcpus=2 -r 768 --os-type=linux --os-variant=rhel6 \
      --network network:default --vnc --accelerate \
      --location ftp://192.168.1.50/pub/inst \
      --extra-args "ks=ftp://192.168.1.50/pub/ks_tester1.cfg"
    5. virt-install -n tester1.example.com \
      --disk path=/var/lib/libvirt/images/tester1.example.org.img,size=12 \
      --vcpus=2 -r 768 --os-type=linux --os-variant=rhel6 \
      --network network:default --vnc --accelerate \
      --location ftp://192.168.1.50/pub/inst \
      --extra-args "ks=ftp://192.168.1.50/pub/ks_tester1.cfg"

Introduction

The following pages contain my notes from studying Michael Jang's RHCSA/RHCE Red Hat Linux Certification Study Guide. Jang's book is incredibly helpful, explaining each objective in great detail. My notes are quite simple in comparison, thus they are merely a supplement to the book. I highly recommend purchasing and studying the book if you plan on taking the exams. Read This Before Continuing! Before we can begin with the lessons, we must first set up a lab where we will be doing all of our studying. A note before we continue: The study lab uses KVM (virtual machines), therefore you will need a CPU that supports hardware virtualization. You can find out if your CPU supports hardware virtualization by checking the manufacturer website for your CPU. For example, if we check the product details for AMD's Phenom N930 , we will see that there is a "Yes" liste d next to "AMD's Virtualization Technology," which means that the CPU supports har
