Install a new CentOS 7.4 VM

Home | Next

Requirements

• A new VM
  • minimum 1 core, 4GB RAM, 32GB disk, 2GB swap, 1 network interface
  • recommended 4 cores, 8GB RAM, 32GB disk, 1 network interface
  • (in real production) 4 cores, 8GB RAM, 32GB disk, 1 network interface
• An installation source
  • CentOS 7.4 DVD ISO
  • or CentOS 7.4 NetInstall ISO and full (and fast) internet access
• A kickstart file
  • (with network) we’ll use this file
  • (with no network) a floppy disk image will be made available with this file

Let’s go!!

1. Create a VM with your favourite hypervisor. If your machine can afford it, give the VM 4GB RAM. For this workshop the number of cores is not important, but you’ll want 4 cores in production. Even in production you won’t need more than 32GB disk.
2. Boot the VM from the ISO, select Install CentOS 7 and press TAB.
3. At the kernel parameters prompt, we’ll add the inst.ks parameter, telling the installer to fetch and use a Kickstart file.
   • (with network, installing from DVD) add inst.ks=https://github.com/cwmoller/workshop-puppet5/raw/master/ks.cfg
   • (with network, installing from internet) add inst.ks=https://github.com/cwmoller/workshop-puppet5/raw/master/ks-net.cfg
   • (with no network, floppy disk image added) add inst.ks=hd:/dev/fd0:/ks.cfg
4. Wait for the installation to complete (shouldn’t be more than 10 minutes)
   While we’re waiting, let’s review what we told kickstart to do.
5. Log in to your new VM
   
   • username: root
   • password: password
