Using this guide

This guide describes installing EGO on a single Linux host for evaluation purposes.

In a single-host cluster, the master host functions as both management and compute host, so you do not need to worry about these concepts. The cluster name is cluster1.

CAUTION:

If you want to install a production cluster, see Planning and Installing Your Cluster on Linux. For a cluster of multiple hosts, you must choose management and compute hosts, and plan the entire cluster more carefully before you install.

Single-host cluster

To install quickly for evaluation purposes, set up a single-host cluster by following the steps in Install a single-host cluster.

Migration to a multiple-host cluster

After you have finished testing or demonstrating your single-host cluster, you can convert your host to the master host of a multiple-host cluster by following the steps in the Appendix.

Do not move this multiple-host cluster into production unless your original host is suitable to become master of a large production cluster. The following is the suggested requirements for the master host of a large production cluster:

  • For a management host (which includes the master host), we suggest at least a 1- or 2-CPU (>2.0GHz) computer with 4GB RAM, 30GB storage.
