Cluster VM node deployment
Exercise
  • Clone your clnode01 virtual machine into a new VM, clnode02. 
    virsh shutdown clnode01
virt-clone --connect=qemu:///system -o clnode01 -n clnode02 -f /home/hostadm/KVM/clnode02.img

  • Start clnode02 and login to its console: 
    virsh start clnode02 
virsh console clnode02
    Change the host name for clnode02 in file /etc/hostname, then 
    cp /dev/null /etc/udev/rules.d/70-persistent-net.rules
reboot

  • On clmaster try to SSH to clnode02 as user hostadm. It should allow SSH login without password authentication. Try also SSH from clnode02 to clnode01.

  • Login to clmaster as user hostadm then, 
    cp ~hostadm/.ssh/known_hosts /etc/ssh/ssh_known_hosts
