#In multi VM cluster. Execute this script in one VM. It will create a sshFix.tar
|
|
|
|
|
#Copy this sshFix.tar to other VMs (/root) in your cluster and execute same script. It will extract previously created keys.
|
|
|
|
|
#This way, all VMs will have same public and private keys in .ssh folder.
