RHCE 8 Automated Practice Deployment

Powered by Ansible and Vagrant

Installation options below:

macOS

Gatekeeper will block virtualbox from installing. All you have to do is go into Security & Privacy of System Preferences and click Allow under the General tab and rerun installation.

Install all at once with the command below:
/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)" && xcode-select --install &&brew install ansible ; brew install python ; brew cask install vagrant ; brew cask install VirtualBox ; brew cask install virtualbox-extension-pack ; vagrant plugin install vagrant-guest_ansible
Alternatively, you can install everything individually below.
Once the above software is installed. Do the following if you're running the environment on Mac:
  1. Create a separate ~/bin directory and cd to it. (The directory doesn't have to be ~/bin, it can be anything you want.)
  2. Clone the environment repo to it with git clone https://github.com/rdbreak/rhce8env.git
  3. Change to the rhce8env directory that is now in your ~/bin directory.
  4. Run vagrant up to deploy the environment (If the environment has a designated repo VM it will take the longest to deploy the first time only, this is because the repo system has all the packages available to the base release but will be quicker on subsequent deployments.)

CentOS/RHEL/Manjaro/Arch - Install all at once by Copy/Pasting the below command into your terminal as root.

NOTE - If it's been awhile since you've run yum update, do that first. Reboot if the kernel was updated. There may be some dependencies errors but don't be alarmed as this won't stop the environment from working.

NOTE2 - If you receive an error for an ansible guest vagrant plugin, DO NOT worry, as there are two different plugins related to Ansible and only one needs to be installed.

For CentoOS/RHEL7/Manjaro/Arch (Continue below for RHEL 8 specific script)
systemctl stop packagekit; yum install -y epel-release && yum install -y git binutils gcc make patch libgomp glibc-headers glibc-devel kernel-headers kernel-devel dkms libvirt libvirt-devel ruby-devel libxslt-devel libxml2-devel libguestfs-tools-c ; mkdir ~/Vagrant ; cd ~/Vagrant ; curl -o  vagrant_2.2.6_x86_64.rpm https://releases.hashicorp.com/vagrant/2.2.6/vagrant_2.2.6_x86_64.rpm && yum install -y vagrant_2.2.6_x86_64.rpm && vagrant plugin install vagrant-guest_ansible ; vagrant plugin install vagrant-guest-ansible ; wget -O /etc/yum.repos.d/virtualbox.repo wget http://download.virtualbox.org/virtualbox/rpm/rhel/virtualbox.repo ; yum install -y VirtualBox-6.0 && systemctl start packagekit
If you're using RHEL 8, use the script below:
systemctl stop packagekit; dnf -y install https://dl.fedoraproject.org/pub/epel/epel-release-latest-8.noarch.rpm ; dnf install -y git binutils gcc make patch libgomp glibc-headers glibc-devel kernel-headers kernel-devel dkms libvirt libvirt-devel ruby-devel libxslt-devel libxml2-devel libguestfs-tools-c ; mkdir ~/Vagrant ; cd ~/Vagrant ; curl -o  vagrant_2.2.6_x86_64.rpm https://releases.hashicorp.com/vagrant/2.2.6/vagrant_2.2.6_x86_64.rpm && dnf install -y vagrant_2.2.6_x86_64.rpm && vagrant plugin install vagrant-guest_ansible ; wget -O /etc/yum.repos.d/virtualbox.repo wget http://download.virtualbox.org/virtualbox/rpm/rhel/virtualbox.repo ; dnf install -y VirtualBox-6.0 && /usr/lib/virtualbox/vboxdrv.sh setup ; usermod -a -G vboxusers root ; systemctl start packagekit
Also, install the Virtualbox extension pack below
Once the above software is installed. Do the following if you're running the environment on Mac:
  1. Create a separate ~/bin directory and cd to it. (The directory doesn't have to be ~/bin, it can be anything you want.)
  2. Clone the environment repo to it with git clone https://github.com/rdbreak/rhcsa8env.git
  3. Change to the rhcsa8env directory that is now in your ~/bin directory.
  4. Run vagrant up to deploy the environment (If the environment has a designated repo VM it will take the longest to deploy the first time only, this is because the repo system has all the packages available to the base release but will be quicker on subsequent deployments.)

Windows/Fedora

dnf -y install wget git binutils gcc make patch libgomp glibc-headers glibc-devel kernel-headers kernel-devel dkms libvirt libvirt-devel ruby-devel libxslt-devel libxml2-devel ; wget http://download.virtualbox.org/virtualbox/rpm/fedora/virtualbox.repo ; mv virtualbox.repo /etc/yum.repos.d/virtualbox.repo ; dnf install -y VirtualBox-6.0 ; usermod -a -G vboxusers ${USER} ; /usr/lib/virtualbox/vboxdrv.sh setup ; dnf -y install vagrant ; dnf remove -y rubygem-fog-core ; vagrant plugin install vagrant-guest_ansible
Once the above software is installed. Do the following if you're running the environment on Windows:
  1. Create a separate ~/bin directory and cd to it using the same PowerShell/Terminal as Administrator/Root.  (The directory doesn't have to be ~/bin, it can be anything you want.)
  2. Use your browser of choice and navigate to https://github.com/rdbreak/rhce8env, press the green “Clone or download” button then the “Download ZIP” button. Or use Github Desktop (See below).
  3. Once downloaded, unzip the file and move it to the directory you created earlier, ~/bin in the above example.
  4. Use PowerShell/Terminal as Administrator/Root again and cd to the ~/bin/rhce8env directory then run vagrant up to deploy the environment. (If the environment has a designated repo VM it will take the longest to deploy the first time only, this is because the repo system has all the packages available to the base release but will be quicker on subsequent deployments.)

Debian

NOTE - If it's been awhile since you've run apt update, do that first. Reboot if the kernel was updated.

Install all at once by Copy/Pasting the below command into your terminal as root.
sudo snap install ruby ; sudo apt install ruby-bundler git -y; wget -c https://releases.hashicorp.com/vagrant/2.2.6/vagrant_2.2.6_x86_64.deb ; sudo dpkg -i vagrant_2.2.6_x86_64.deb ; wget -q https://www.virtualbox.org/download/oracle_vbox_2016.asc -O- | sudo apt-key add - ; wget -q https://www.virtualbox.org/download/oracle_vbox.asc -O- | sudo apt-key add - ; sudo add-apt-repository "deb http://download.virtualbox.org/virtualbox/debian bionic contrib"; sudo apt update; sudo apt install -y virtualbox-6.0 ; vagrant plugin install vagrant-guest_ansible
Also, install the Virtualbox extension pack below
Once the above software is installed. Do the following if you're running the environment on Linux:
  1. Create a separate ~/bin directory and cd to it. (The directory doesn't have to be ~/bin, it can be anything you want.)
  2. Clone the environment repo to it with git clone https://github.com/rdbreak/rhce8env.git
  3. Change to the rhce8env directory that is now in your ~/bin directory.
  4. Run vagrant up to deploy the environment (If the environment has a designated repo VM it will take the longest to deploy the first time only, this is because the repo system has all the packages available to the base release but will be quicker on subsequent deployments.)

Also, don't be spooked by any scary red font during the setup process. There are known issues that won't have a negative affect on the environment.

Now the deployment should be up and running!

(Recommended) Install Github Desktop to make pulling down changes easier

NOTE this requires a free Github account

  1. Navigate to https://desktop.github.com/ and download Github Desktop.
  2. Create or sign in to your account.
  3. Click "Clone a repository from the Internet" and enter "rdbreak/rhce8env" and choose a location then "Clone".
  4. You are also able to easily pull changes when they're made available.

Notable Vagrant Commands to control the environment:

  • ansible-playbook playbooks/reset.yml - Used for resetting the environment after attempting the practice exam in the Red Hat Certs Slack workspace practice exam channel.
  • vagrant up - Boots and provisions the environment
  • vagrant destroy -f - Shuts down and destroys the environment
  • vagrant halt - Only shuts down the environment VMs (can be booted up with vagrant up)
  • vagrant suspend - Puts the VMs in a suspended state
  • vagrant resume - Takes VMs out of a suspended state

Other Useful Information:

You can also use the VirtualBox console to interact with the VMs or through a terminal. If you need to reset the root password, you would need to use the console. I'm constantly making upgrades to the environments, so every once and awhile run git pull in the repo directory to pull down changes. If you're using Windows, it's recommended to use Github Desktop so you can easily pull changes that are made to the environment. The first time you run the vagrant up command, it will download the OS images for later use. In other words, it will take longest the first time around but will be faster when it is deployed again. You can run vagrant destroy -f to destroy your environment at anytime. This will erase everything. This environment is meant to be reuseable, If you run the vagrant up command after destroying the environment, the OS image will already be downloaded and environment will deploy faster. Deployment should take around 15 minutes depending on your computer. You shouldn't need to access the IPA server during your practice exams. Everything should be provided that you would normally need during an actual exam. Hope this helps in your studies!

Known Issues:

Running the 'vagrant up' environment build will fail If HyperV is installed on the Windows VirtualBox host. Error is usually "VT-x is not available. (VERR_VMX_NO_VMX)" or similar, when the script attempts to boot the first VM.

Resolution seems to be either remove HyperV, or preventing its hypervisor from starting with the command: bcdedit /set hypervisorlaunchtype off, followed by a reboot.
