2. Installing Virtuozzo PowerPanel¶
To install Virtuozzo PowerPanel, you need to deploy one controller (management) node and after that as many compute nodes as required. The following sections describe these procedures in detail.
Installation is performed by means of Ansible playbooks.
The following requirements that must be met to install Virtuozzo PowerPanel:
The controller can only be deployed on Virtuozzo Linux 7 or CentOS 7 installed on a physical host or in a virtual machine or container. It cannot be installed on Virtuozzo Hybrid Server 7 or inside a Virtuozzo Automator container.
The controller’s physical or virtual environment must have at least 2 CPU cores and 8GB of RAM.
The compute component can only be installed on a Virtuozzo Hybrid Server 7 host.
Operating systems on the controller and all compute nodes must be fully updated.
Each node in the PowerPanel cluster—the controller and all computes—must have a fully qualified domain name (FQDN) and be accessible by it.
Time must be synchronized on the controller and all compute nodes. For example, by running on each node
yum install ntpdate && ntpdate pool.ntp.org.
It is also recommended to do the following:
Connect the controller node to two networks: (a) internal for communication with compute nodes and (b) external for public access.
Connect compute nodes to an internal network. Let only VMs and containers on compute nodes have public access.
Make sure that all compute nodes are configured to store backups locally. This is required for attaching backups to VEs to work.
