Chapter 1. Installation Overview
Chapter 1. Installation Overview The self-hosted engine installation uses Ansible and the RHV-M Appliance (a pre-configured Manager virtual machine image) to automate the following tasks: Configuring the first self-hosted engine node Installing a Red Hat Enterprise Linux virtual machine on that node Installing and configuring the Red Hat Virtualization Manager on that virtual machine Configuring the self-hosted engine storage domain Note The RHV-M Appliance is only used during installation. It is not used to upgrade the Manager. Installing a self-hosted engine environment involves the following steps: Prepare storage to use for the self-hosted engine storage domain and for standard storage domains. You can use one of the following storage types: NFS iSCSI Fibre Channel (FCP) Red Hat Gluster Storage Install a deployment host to run the installation on. This host will become the first self-hosted engine node. You can use either host type: Red Hat Virtualization Host Red Hat Enterprise Linux Install and configure the Red Hat Virtualization Manager: Enabling and configuring the firewall Install the self-hosted engine using the hosted-engine --deploy command on the deployment host. Register the Manager with the Content Delivery Network and enable the Red Hat Virtualization Manager repositories. Connect to the Administration Portal to add hosts and storage domains. Add more self-hosted engine nodes and standard hosts to the Manager. Self-hosted engine nodes can run the Manager virtual machine and other virtual machines. Standard hosts can run all other virtual machines, but not the Manager virtual machine. Use either host type, or both: Red Hat Virtualization Host Red Hat Enterprise Linux Add hosts to the Manager as self-hosted engine nodes. Add hosts to the Manager as standard hosts. Add more storage domains to the Manager. The self-hosted engine storage domain is not recommended for use by anything other than the Manager virtual machine. If you want to host any databases or services on a server separate from the Manager, you can migrate them after the installation is complete. Important Keep the environment up to date. See How do I update my Red Hat Virtualization system? for more information. Since bug fixes for known issues are frequently released, use scheduled tasks to update the hosts and the Manager.
