To Configure the Distributed Authentication UI Servers Load Balancer

Before You Begin

Contact your network administrator to obtain an available virtual IP address.

The load balancer hardware and software used in the lab facility for this deployment is BIG-IP® manufactured by F5 Networks. If you are using different load balancer software, see the documentation that comes with that product for detailed settings information.

1. Create a Pool.

   A pool contains all the backend server instances.

   1. Go to URL for the Big IP load balancer and log in.

   2. Open the Configuration Utility.

      Click “Configure your BIG-IP (R) using the Configuration Utility.”

   3. In the left pane, click Pools.

   4. On the Pools tab, click the Add button.

   5. In the Add Pool dialog, provide the following information:

      Pool Name

      Example: AuthenticationUI-Pool

      Load Balancing Method

      Round Robin

      Resources

      Add IP addresses for the Distributed Authentication UI server hosts. For this example, add AuthenticationUI-1:1080 and AuthenticationUI-2:1080.

   6. Click the Done button.

2. Configure the load balancer for persistence.

   1. In the left frame, click Pools.

   2. Click the DistributedUI-Pool link.

   3. Click the Persistence tab.

   4. Under Persistence Type, choose Passive HTTP Cookie, and then click Apply.

3. Add a Virtual Server.

   1. In the left frame, Click Virtual Servers.

   2. On the Virtual Servers tab, click the Add button.

   3. In the Add Virtual Server wizard, enter the virtual server IP address and port number.

      In this example, enter the IP address for Load Balancer 4, and enter the port number 90.

   4. Continue to click Next until you reach the Pool Selection dialog box.

   5. In the Pool Selection dialog box, assign the AuthenticationUI-Pool that you have just created.

   6. Click the Done button.

4. Add monitors.

   Monitors are necessary for the load balancer to detect any backend server failures that may occur.

   1. In the left frame, click Monitors.

   2. Click the Basic Associations tab.

   3. Add an HTTP monitor to each Web Server node.

      In the Node list, locate the IPaddress:port of the node for which you are creating the monitor. Select the Add checkbox.

   4. Click Apply.

5. Verify that the Distributed Authentication UI server load balancer is configured properly.

   Start a new browser and go to the Distributed Authentication UI load balancer URL. Example:

   http://LoadBalancer-4.example.com:90/.

   If the browser successfully renders the default Sun Web Server default document root page, close the browser.
