Press ‘y’ key to continue the installation process.Īfter the installation is complete with required packages of corosync and pacemaker on both the nodes, we are going to configure the Corosync, So that both the servers can communicate as a cluster.

#How to install haproxy on ubuntu 14.04 install#

# apt-get install pacemakerĬorosync will be installed as a dependency of the pacemaker. Now we are going to install the Corosync and Pacemaker packages on both servers using the following command. Step 3: Installing Corosync and Pacemaker

Select the same time on both servers and then update your servers followed by the installation of ‘ntp’ package by using the below commands.Īfter time zone setup run the command to update your system once again. Let’s run the following command on both the server nodes. In clusters each node have to communicate with the other node. Time synchronization is important when you are working on setting up the clusters.

You will see the following page after pointing the IP address of your server in the web browser. You will see the same contents by pointing the original IP address or the floating IP address. Once you have assigned the floating IP to your Primary server, open your web browser followed by the Floating IP address. You can generate your new floating IP from the cloud console and assign it the the Primary node. So as the Part of a highly available infrastructure, we need to immediately point an IP address to a redundant server. Step 2: Configure Floating IPĪ Floating IP is an IP address that can be instantly moved from one Node to another Node in the same datacenter. Save and close the configuration file and update the secondary node with its host name and IP address. You can do so by adding your host information using your editor. Now replace the contents of ‘index.html’ with your primary and secondry hostname and IP address which will be useful for testing which Node the Floating IP is pointing to at any given moment. Now login to both your servers using the sudo user and run the following commands on both servers as a root to update your servers, install the Nginx web server and then configure the default web page with some test contents that represents the name of the current node. Make sure that on each node Private Networking option should be enabled. Here we will be using ‘Ubuntu-14-P’ for our primary node and ‘Ubuntu-14-S’ for the secondary node. The first step is to create 2 separate Ubuntu nodes and configure their FQDN’s that represents them. We will follow the steps in the following sequence to setup the fully functional HAProxy on Ubuntu 14.04.Ģ – Create Floating IP to assign to one node.ħ – Configure Nginx Cluster Resource Step 1: Creating 2 Ubuntu Nodes Then we need a floating IP address to be assigned with any one node that will be used for the fail over. In order to complete this article we need to build two nodes with Ubuntu 14.04 Operating System installed and setup their unique FQDN.

In a situation when the Primary node fails the secondary node will become active using the script that will reassign the floating IP to the secondary node to serve the incoming traffic. The users will access the web services from the primary node unless any failure is detected by the pacemaker. We are going to setup the High Availability Cluster that will consist of two Ubuntu 14.04 servers accomplished with a Floating IP in active/passive configurations. It implements several APIs for controlling resources, but its preferred API for this purpose is the Open Cluster Framework resource agent API.

Pacemaker is an open source high availability resource manager software used on computer clusters that manages the resources and applications on a node within the cluster. Corosync effort is to develop, release, and support a community-defined, open source cluster executive for use by multiple open source and commercial cluster projects or products that provides messaging between servers within the same cluster. It allows any number of servers to be part of the cluster using any number of fault-tolerant configurations (active/passive, active/active, N+1, etc.). The Corosync Cluster Engine is an open source project derived from the OpenAIS project licensed under the new BSD License. In this tutorial we will cover the build of a two-node high-availability cluster using the Corosync cluster engine, and the Pacemaker resource manager on Ubuntu 14.04 with a Floating IP to create a high availability (HA) server infrastructure on our Cloud Enviroment. A high availability architecture is one of the key requirements for any Enterprise Deployment network.
