4. prep_ssh.sh – generates secure shell keys and configuration files, and temporarily

places these files on the GFS2 volume for passing to the other cluster member

#!/bin/bash

# This script will create a FS for temporary use on the disk to be

# used for GFS2, generate ssh config and copy the ssh config to this disk

#Create ext2 file system

mkfs /dev/mapper/GFS2_disk

#Mount temp file system

mount /dev/mapper/GFS2_disk /mnt

#Create the .ssh dir and generate individual and cluster RSA key pairs

mkdir /root/.ssh

chmod 700 /root/.ssh

ssh-keygen -q -t rsa -N "" -f /root/.ssh/id_rsa

#Add the public key to the authorized keys

/bin/cp /root/.ssh/id_rsa.pub /root/.ssh/authorized_keys

#Add cluster key and allow ssh to automatically add all hosts to the

#host file as they connect

echo StrictHostKeyChecking no >> /root/.ssh/config

#Copy the ssh configuration to the temp file system and unmount

/bin/cp /root/.ssh/id_rsa /root/.ssh/id_rsa.pub /root/.ssh/authorized_keys /root/.ssh/config /mnt/

umount /mnt
