Step-Step Install Guide Enterprise Application Servers

with Proxmox VE Cluster

By Kefa Rabah, [email protected] August, 2011 GTS Institute

Introduction

In this Hands-on lab, you’re going to learn how to install and configure Proxmox Virtual Environment (VE)

server – a professional virtualization platform used to make virtual machines based on KVM and OpenVZ

technologies. Proxmox VE is an easy to use open source virtualization platform based on Linux and used

for running virtual appliances and virtual machines. It is a product aimed at companies and production

environments, since it intends to be an easy deployment and management solution. Proxmox VE is

licensed under GPLv2 (Open source). Open source and commercial Virtual Appliances are supported.

Proxmox VE supports all hardware supported by the Linux kernel, and the developers have designed their

own method of clustering multiple Proxmox VE servers together in order to enable live migration and

central management from the web interface. Performance is extremely good, and it also supports virtual

machine storage on a variety of network storage types, including NFS, CIFS, and iSCSI. Because the

underpinnings of Proxmox VE is based on Debian distro, other Linux-based solutions can be added with

little difficulty for a Linux expert, such as glusterfs for clustered virtual machine storage, etc. Proxmox VE

also ships with OpenVZ capabilities, allowing one to create Linux virtual containers rather than virtual

machines. These have been found to have much less I/O and memory overhead and allow one to run

multiple Linux environments very quickly on the native hardware.

Proxmox VE Cluster: PVE can be run as a cluster. Clustering brings several advantages. The biggest is

the ability to migrate your virtual machines between cluster nodes, live without shared storage. Another

benefit is the ability to manage multiple servers from one unified web interface. You are able to create

virtual machines from the cluster master node on any of the cluster slave nodes. If your master node fails

the slave nodes are still able to function although the cluster is down so migrations will no longer be

available, however the virtual machines will still work as normal.

Hands-on Labs

In this Hands-on Lab session, you’ll learn how to install and configure Proxmox VE. Next, you’ll learn how

to build and deploy virtual machines on Proxmox VE. In this lab you’ll have an opportunity to deploy

CentOS-5 VM server which you can use to deploy other applications. You'll also learn how to install and

configure enterprise solutions e.g., SugarCRM, Moodle LMS, Joomla CMS, eyeOS Cloud, Secure Web

Proxy Server, Proxmox Mail Gateway proxy server, and WordPress blog. You'll also learn how to perform

live migration of virtual machine from one cluster node to another. Once you have gained enough

expertise working with Proxmox VE cluster, you can then think to use it to build & deploy private cloud

using OpenNebula, Eucalyptus Systems etc. or any other applications as desired.

You’re now ready to install and configure your application servers as listed above.

Part 1: Installing and Updating Proxmox VE Server

Proxmox VE supports three types of virtualization technologies:

• Container virtualization (OpenVZ): it allows that a physical server can run multiple insolated

operating system instances as well known as containers. Its main problem is these containers or

guests can just be Linux instances. However, the OpenVZ kernel provides better performance

(penalty between 1% and 3% compared to a standalone server) in contradistinction to other

alternatives.

• Full virtualization (KVM): it can run Linux and Windows guests but unlike OpenVZ, Intel VT or

AMD-V CPU is needed.

• Paravirtualization (KVM): it presents a software interface similar to the underlying hardware in

order to try to reduce the execution time of certain operations.

Note: in our lab, we think that OpenVZ is a plus because it has got better performance than KVM and

the containers idea is fantastic: the size of these templates is really small and you can get a ready

virtual machine in few minutes.

Step 1: Getting Started & Hardware Pre-requisites

1.1 System requirements

For production servers, high quality server equipment is needed. Keep in mind, if you run 10 Virtual

Servers on one machine and you got a hardware failure, 10 services are lost. Proxmox VE supports

clustering, means that multiple Proxmox VE installations can centrally managed via the included cluster

functionality.

Note: Proxmox VE can also use local storage (DAS) and SAN.

Minimum requirements for evaluation:

• CPU: 64bit (Intel EMT64 or AMD64), Intel VT/AMD-V capable CPU/Mainboard (for KVM Full

Virtualization support)

• Minimum 1 GB RAM

• Hard drive

• One NIC

Recommended system requirements:

• CPU: 64bit (Intel EMT64 or AMD64), Multi core CPU recommended, Intel VT/AMD-V capable

CPU/Mainboard (for KVM Full Virtualization support)

• 4 GB is good, more is better

• Hardware RAID with batteries protected write cache (BBU)

• Fast hard drives, best results with 15k rpm SAS, Raid10

• Two NIC

1.2 Summary of Proxmox VE Installation

Proxmox VE installs the complete operating system and management tools in 3 to 5 minutes (depends on

the used hardware).

"Bare-metal" means that you start from a empty server - there is no need to install a base operation

system.

Including the following:

• Complete operating system (Debian Lenny 64)

• Partition the hard drive with LVM2

• Proxmox VE Kernel with OpenVZ and KVM support

• Backup/Restore tools

• Web based management interface

• Proxmox uses LVM - See backup and restore of LVM data.

Warning: the complete server is used and all existing data is removed.

Step 2: Install Proxmox Virtual Environment (VE), Master “server01.govcloudgo.com”

1. Hope over to http://www.proxmox.com/downloads/proxmox-ve/17-iso-images website and download

Part 2: Creating a Cluster by Adding a Slave Node (server02.govcloudgo.com)

In this section you’ll learn how you can create a cluster or computing cloud by adding one or multiple slave

(node) servers to the Proxmox master (server01.govcloudgo.com). Such a cloud infrastructure

allows you to create and manage virtual machines on remote hosts from the Proxmox control panel, and

you can also perform live migration of virtual machines from one host to another.

1. I’ll now show you how to add a second host, ″server02.govcloudgo.com″, and create a cluster.

To do this, just repeat the steps to install Proxmox just as you did on ″server01″. However, when

you come to the Network Configuration section, fill in ″server02.govcloudgo.com″, and make

sure you use a different IP (e.g., 192.168.83.133), as shown in Fig. 17.




15

Fig. 17

2. After the installation is completed, and the system has successfully rebooted, you should be brought

terminal console as shown in Fig. 18.

Fig. 18

3. Now, open the terminal console (you may also use PutTTY) on both server01 and server02, and

perform the next procedures.




16

4. On server01, issue the following command:

pveca -c

Fig. 19

Note: when done, you should see: ″cluster Master successfully created″.

5. Next, check the status of the cluster, run command:

pveca -l

Fig. 20

6. Let’s check the connectivity between the hosts. To do this, from server02, test that you can ping

server01, issue the command ping command:

Fig. 21




17

which show excellent connectivity!

7. We're now set to continue, again from server02, run the command:

pveca -a -h 192.168.83.132

Fig. 22

Note: when prompted, answer ″yes″, and then enter password of the master server, server01.

When done you should see: ″cluster node successfully created″.

8. That's it, we're done creating a cluster. You can verify this from server02, by running

pveca -l

Fig. 23

9. Finally, head back to the Proxmox VE control panel for server01 by pointing your browser to:

https://192.168.83.132/, and go to the Cluster section, and you should observe both the

servers listed, as shown in Fig. 24.
