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 CID----IPADDRESS----ROLE-STATE--------UPTIME---LOAD----MEM---ROOT---DATA 1 : 192.168.7.104 M A 5 days 01:43 0.54 20% 1% 4% 2 : 192.168.7.103 N A 2 days 05:02 0.04 26% 5% 29% 3 : 192.168.7.105 N A 00:13 1.41 22% 3% 15% 4 : 192.168.7.106 N A 00:05 0.54 17% 3% 3%
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.
