Creating a Cluster Node (Active)

1. Select Azure Portal > Virtual machines > Add and enter the basics settings.

Use the following values:

• Note 1: Availability Sets are a prerequisite for LifeKeeper clusters on Azure and must be set up.
  
  
• Note 2: Select the OS version supported by LifeKeeper to be installed. Refer to the Support Matrix OS versions supported by LifeKeeper.
  
  
• Note 3: Be sure to select an instance size for the Availability Set. Availability Sets are not available for some instance sizes.
  
  
• Note 4: Be sure to select an instance size for the load balancing rules that can be applied. Load balancing rules are not available for some instance sizes.

2. Once the required values are entered click Next:Disks.

3. Configure the disk settings. In this case, a disk for Oracle DB (30GiB) and a disk for swap area (10GiB) are required in addition to the OS disk.

Click Create and attach a new disk to assign additional disks.

Use the following values:

• Note 1: In this case, the cache is disabled for database use and should be configured appropriately according to your requirements.

4. Once the required values are entered click Next:Networking.

5. Enter the network settings.

At this time, configure the first subnet that you created in the previous step for the virtual machine. This setting attaches a single network interface. The second network interface is configured after the virtual machine is created.

Use the following values:

• Note 1: Configure the first subnet that you created in the previous step for the virtual machine.
  
  
• Note 2: In this procedure the Public IP has been set to access via the Internet.

6. Configure administrative settings, advanced settings, and tag settings if necessary, then click Review + Create.

7. Review the details and click Create. When deployed with the above configuration, Red Hat Enterprise Linux starts with the installation completed.

8. Stop the virtual machine to change the network configuration.

9. Change the first network interface to a static IP address. Click Azure Portal > Virtual machines > (virtual machine name) > Networking > (first interface name).

10. Click IP configurations > ipconfig1. At this point the IP address is set to Dynamic.

11. Change the IP address setting to static.

Use the following values:

12. Click Save to save the settings.

13. Edit the network security group to allow the Oracle listener service to communicate using TCP Port 1521. Click Azure Portal > Virtual machines > (virtual machine name) > Networking > (first interface name) > Network security group > (security group name).

14. Click Inbound security rules > Add.

15. Add inbound rules.

Use the following values:

• Note 1: Since the Oracle listener uses port1521, communication to the relevant port is permitted.

16. Click Add to save your settings.

17. Next, add a second network interface. Click Azure Portal > Virtual machines > (Virtual machine name) > Networking > Attach network interface.

18. Click Create network interface.

19. After entering the required values, click Create.

Use the following values:

• Note 1: Set the second subnet created in the previous step for the virtual machine.

20. Click OK.

21. Make sure that the two interfaces are attached.

22. Start the virtual machine.
