Introduction

Proxmox VE Cluster enables central management of multiple physical servers. A Proxmox VE Cluster consists of one master and several nodes (minimum is a master and one node).

Main features

  • Centralized web management
  • One login and password for accessing all nodes and guests
  • Console view to all Virtual Machines
  • Migration of Virtual Machines between physical hosts
  • Synchronized Virtual Appliance template store

Create a Proxmox VE Cluster

First, install two Proxmox VE servers, see Installation. Make sure that each Proxmox VE server has a unique host name, by default all server has the same host name.

Currently the cluster creation has to be done on the console, you can login to the Proxmox VE server via ssh.

All settings can be done via "pveca", the PVE Cluster Administration Toolkit

USAGE: pveca -l             # show cluster status
       pveca -c             # create new cluster with localhost as master
       pveca -s [-h IP]     # sync cluster configuration from master (or IP)
       pveca -d ID          # delete a node
       pveca -a [-h IP]     # add new node to cluster
       pveca -m             # force local node to become master

Define the master

Create the master:

pveca -c

To check the state of cluster:

pveca -l

Add a node to an existing master

Login via ssh to a second Proxmox VE server.

Join a node to the master:

pveca -a -h IP-ADDRESS-MASTER

To check the state of cluster:

pveca -l

Display the state of cluster:

pveca -l

Working with Proxmox VE Cluster

Now, you can start creating Virtual Machines on Cluster nodes by using the Central Web-based Management on the master.
