Create a new XML configuration file that will extend the current compute.xml configuration file:
# cd /export/rocks/install/site-profiles/7.0/nodes/ # cp skeleton.xml extend-compute.xml
If you want to include your customizations in all cluster nodes (and not just the compute nodes) you should use extend-base.xml as a file name instead of extend-compute.xml.
Inside extend-compute.xml, add your configuration scripts that will be run in the post configuration step of the Red Hat installer.
Put your bash scripts in between the tags <post> and </post>:
<post> < !-- insert your scripts here --> </post>
To apply your customized configuration scripts to compute nodes, rebuild the distribution:
# cd /export/rocks/install # rocks create distro
Then, reinstall your compute nodes.
