Chapter 11. Deploy the Hosted Engine using the Web Console
Chapter 11. Deploy the Hosted Engine using the Web Console This section shows you how to deploy the Hosted Engine using the Web Console. Following this process results in Red Hat Virtualization Manager running as a virtual machine on the first physical machine in your deployment. It also configures a Default cluster comprised of the three physical machines, and enables Red Hat Gluster Storage functionality and the virtual-host tuned performance profile for each machine in the cluster. Prerequisites The RHV-M Appliance is installed during the deployment process; however, if required, you can install it on the deployment host before starting the installation: Manually installing the Manager virtual machine is not supported. Configure Red Hat Gluster Storage for Hosted Engine using the Web Console Gather the information you need for Hosted Engine deployment Have the following information ready before you start the deployment process. IP address for a pingable gateway to the hyperconverged host IP address of the front-end management network Fully-qualified domain name (FQDN) for the Hosted Engine virtual machine MAC address that resolves to the static FQDN and IP address of the Hosted Engine Procedure Open the Hosted Engine Deployment wizard If you continued directly from the end of Configure Red Hat Gluster Storage for Hosted Engine using the Web Console , the wizard is already open. Otherwise: Click Virtualization Hosted Engine . Click Start underneath Hyperconverged . Click Use existing configuration . Important If the deployment attempt failed, click Clean up instead of Use existing configuration to discard the attempt and start from scratch. If your deployment uses Network-Bound Disk Encryption, you must then follow the process in Cleaning up Network-Bound Disk Encryption after a failed deployment . Specify virtual machine details Enter the following details: Engine VM FQDN The fully qualified domain name to be used for the Hosted Engine virtual machine, for example, engine.example.com . MAC Address The MAC address associated with the Engine VM FQDN . Important The pre-populated MAC address must be replaced. Network Configuration Choose either DHCP or Static from the Network Configuration drop-down list. If you choose DHCP , you must have a DHCP reservation for the Hosted Engine virtual machine so that its host name resolves to the address received from DHCP. Specify its MAC address in the MAC Address field. If you choose Static , enter the following details: VM IP Address - The IP address must belong to the same subnet as the host. For example, if the host is in 10.1.1.0/24, the Hosted Engine virtual machine's IP must be in the same subnet range (10.1.1.1-254/24). Gateway Address DNS Servers Bridge Interface Select the Bridge Interface from the drop-down list. Root password The root password to be used for the Hosted Engine virtual machine. Root SSH Access Specify whether to allow Root SSH Access.The default value of Root SSH Access is set to Yes . Number of Virtual CPUs Enter the Number of Virtual CPUs for the virtual machine. Memory Size (MiB) Enter the Memory Size (MiB). The available memory is displayed to the input field. Note Red Hat recommends to retain the values of Root SSH Access, Number of Virtual CPUs and Memory Size to default values. Optionally expand the Advanced fields. Root SSH Public Key Enter a Root SSH Public Key to use for root access to the Hosted Engine virtual machine. Edit Hosts File Select or clear the Edit Hosts File check box to specify whether to add entries for the Hosted Engine virtual machine and the base host to the virtual machine's /etc/hosts file. You must ensure that the host names are resolvable. Bridge Name Change the management Bridge Name, or accept the default ovirtmgmt. Gateway Address Enter the Gateway Address for the management bridge. Host FQDN Enter the Host FQDN of the first host to add to the Manager. This is the front-end FQDN of the base host you are running the deployment on. Network Test If you have a static network configuration or are using an isolated environment with addresses defined in /etc/hosts , set Network Test to Ping . Click . Your FQDNs are validated before the screen appears. Specify virtualization management details Enter the password to be used by the admin account in the Administration Portal. You can also specify an email address for notifications, the notifications can also be configured post deployment; see Chapter 15, Post-deployment configuration suggestions . Click . Review virtual machine configuration Ensure that the details listed on this tab are correct. Click Back to correct any incorrect information. Click Prepare VM . Wait for virtual machine preparation to complete. If preparation does not occur successfully, see Viewing Hosted Engine deployment errors . Click . Validate storage for the Hosted Engine virtual machine Ensure that the Mount Options field is populated correctly with backup-volfile-servers=<host2-ip-address>:<host3-ip-address> and, if you use IPv6, xlator-option=transport.address-family=inet6 , for example: Click . Finalize Hosted Engine deployment Review your deployment details and verify that they are correct. Note The responses you provided during configuration are saved to an answer file to help you reinstall the hosted engine if necessary. The answer file is created at /etc/ovirt-hosted-engine/answers.conf by default. This file should not be modified manually without assistance from Red Hat Support. Click Finish Deployment . Wait for deployment to complete This can take some time, depending on your configuration details. The window displays the following when complete. Important After RHHI-V deployment is completed successfully, the other 2 Red Hat Virtualization hosts are rebooted. Wait for these hosts to be up, after which the Red Hat Virtualization Administration portal can be accessible. If deployment does not complete successfully, see Viewing Hosted Engine deployment errors . Click Close . Verify hosted engine deployment Browse to the Administration Portal (for example, http://engine.example.com/ovirt-engine ) and verify that you can log in using the administrative credentials you configured earlier. Click Dashboard and look for your hosts, storage domains, and virtual machines. steps Log in to the Administration Portal to complete configuration .
