good afternoon Jenner and JC Bollinger:
the question is connected to deployment (installation and configuration) of
VCS. since VCS is quite popular in the indiustry, this will help many
people.
thank you Jenner and JCB for your informative responses. i apologize
because my initial response to Jenner was not really nice. i was stressed
due to the deadline. i Normally do not use ¬that language and tone¬.
initially, i hesitated to explain which software had to be deployed, but
now, here goes:
- we want to deploy Veritas Cluster Server (high-availability cluster
software) onto multiple RHEL Nodes from a separate RHEL management node.
- Puppet Master runs on the Manager and each Node runs Puppet Agent.
- VCS software is a collection of RPMs with a separate installer executable.
- software can be installed using the Installer that uses SSH to install
the RPMs onto multiple nodes, given the list.
- software can also be installed by simply installing the RPMs directly on
each Node.
- the VCS RPMs have to be installed in a specifc order.
- once the RPMs are installed, a second Installer program is available on
each Node, allowing Cluster Creation from one of the Nodes.
Questions
- which Puppet resource can we use to run the VCS software installer
executable from the Puppet Master?
the list of Nodes is to be passed to the Installer.
- if we want to install the VCS RPMs directly ourselves onto multiple
Nodes, we can:
- use Puppet 'package' on each Node or
- use 'exec' on the manager to ssh and yum RPMs to multiple Nodes.
is there a better way to use Puppet for this?
- VCS comes with:
- an Installer to install VCS software onto all Nodes;
- an Config program to create the Cluster;
- CLI commands to create resources to be monitored.
so, i think that it would be best to use Exec to run these programs.
finally, we are also considering the use of MCollective.
thank you,
Aaron
