This is a summary of the steps to take when creating a small production cluster.
This book describes how to build a production-ready cluster. A specific example is provided as a guide. If you understand this example, you can adjust the procedures as required at your site to build your own cluster.
Read this example to understand how to create a small cluster that can grow into a regular production cluster with master host failover.
Our cluster has the following custom characteristics:
Our cluster has the following hosts:
Additionally, our cluster uses a database host that is not part of the cluster.
We will set up the file server and the master host and test that necessary services have started. We will add a compute host to the cluster. We will add a master candidate host and enable failover in the cluster. Once these important steps are done, we can expand the cluster by adding more management or compute hosts.
Install the master host (see Install the Master Host)
The following is a summary of what to do on HostM (the master host):
Install a compute host (see Install a Compute Host)
The following is a summary of what to do on HostC (a compute host):
Install a management host that is a master candidate host (see Install a Management Host and Enable master host failover)
The following is a summary of what to do on HostD (a master candidate host):
egoadmin(optional).
Configure the master candidate host as a management host.
HostD is now a management host, but is not a master candidate host yet.
Use the web server to configure the master list for failover.
HostD is now a master candidate host. If HostM fails, HostD should take over as master.
