The following steps show how to install your own DNS server into Red Hat Enterprise Linux 5.5
These steps were developed as part of my ten part blog series on installing your own Oracle 11gR2 RAC cluster on VMWare Workstation 8.
I am re-blogging this as a separate post for the sake of clarity to those not interested in the RAC components.
First, locate and mount your RHEL 5.5 install media.
Oracle 11gR2 RAC Grid install includes a useful script to establish and exchange ssh keys between hosts of the cluster.
The process to set up and exchange ssh keys between hosts to facilitate unchallenged logins between trusted users has been well documented already. Oracle simply provides a handy wrapper script over the whole process.
Although the main Grid install process will set up ssh keys, this is a useful verification step to ensure all nodes are reachable, as well as a prerequisite to having the cluvfy script succeed.
The Oracle 11gR2 Grid installer includes a useful verify utility called runcluvfy.sh. This script is found in the grid directory, the same directory where you find runInstaller
The following shows the output of running runcluvfy.sh against a VMWare based RAC.
