Install and configure IBM® Load
Balancer to distribute workload among a cluster of TURN servers.
Before you begin
Create the cluster of servers first. Then configure the
cluster and start the deployment manager as well as all node agents
and application servers within the cluster.
Procedure
-
On the computer where you will install IBM Load Balancer, log on as root (AIX® or Linux™) or as the system administrator (Microsoft™ Windows™).
- Find the software packages
you need to download.
- Download the packages.
- Extract all downloaded packages.
- Navigate to the folder where you extracted the installation package, locate the folder for IBM Load Balancer, and start the installation program.
For instructions on installing IBM Load Balancer, see the Load Balancer Administration Guide, which can be downloaded from the WebSphere® Application Server - Edge Components site.
- After you have installed IBM Load
Balancer, configure two static IP addresses for it:
- Non-Forwarding Address: The NFA is the address of the server
itself. It is used for logging in and administering the load balancer.
- Cluster Address: This is the address by which clients and
other servers will access the cluster. It must be DNS-resolvable.
For example, suppose your cluster contains two nodes, and
you configure an IBM Load Balancer
for the cluster. Your IP addresses will look like this:
