To Configure the Distributed Authentication User Interface Load Balancer

Before You Begin

• This procedure assumes that you have already installed a load balancer.

• 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.

• Contact your network administrator to obtain two available virtual IP addresses.

• Know the IP address of the load balancer hardware, the URL for the load balancer login page, and a username and password for logging in to the load balancer application.

• Get the IP addresses for Distributed Authentication User Interface 1 and Distributed Authentication User Interface 2 by running the following command on each host machine:

  # ifconfig -a

1. Access https://is-f5.example.com, the Big IP load balancer login page, from a web browser.

2. Log in using the following information.

   User name:

   username

   Password:

   password

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

4. Create a Pool.

   A pool contains all the backend server instances.

   1. In the left pane, click Pools.

   2. On the Pools tab, click Add.

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

      Pool Name

      AuthenticationUI-Pool

      Load Balancing Method

      Round Robin

      Resources

      Add the IP address and port number of both Distributed Authentication User Interface host machines: AuthenticationUI-1:1080 and AuthenticationUI-2:1080.

   4. Click Done.

5. Add a Virtual Server.

   This step defines instances of the load balancer.

   1. In the left frame, Click Virtual Servers.

   2. On the Virtual Servers tab, click Add.

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

      Address

      Enter the IP address for LoadBalancer-4.example.com

      Service

      90

      Pool

      AuthenticationUI-Pool

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

   5. In the Pool Selection dialog box, assign the AuthenticationUI-Pool Pool.

   6. Click Done.

6. Add Monitors.

   Monitors are required for the load balancer to detect the backend server failures.

   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 IP address and port number for AuthenticationUI-1:1080 and AuthenticationUI-2:1080, and select the Add checkbox.

   4. Click Apply.

7. Configure the load balancer for persistence.

   1. In the left frame, click Pools.

   2. Click the AuthenticationUI-Pool link.

   3. Click the Persistence tab.

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

8. To verify that the Distributed Authentication User Interface load balancer is configured properly, access http://LoadBalancer-4.example.com:90/ from a web browser.

   If the browser successfully renders the default Web Server document root page, the load balancer has been configured properly.
