Set up the network and hardware
Before starting with the installation of Exasol, the network environment and the cluster hardware must be set up and configured. For more information, refer to Prepare the Environment.
Installation of the software and cluster configuration
The installation process covers the following main tasks:
- Install the Management Node (License Server)
The management node is the only node of a cluster that boots from local disk. It is installed from the Exasol installation ISO image and is used to bootstrap (cold boot) the data nodes over the network via PXE (DHCP + TFTP).
- Configure user access and system security
Set the disk passwords and change the password of the default user; create additional system users if required.
- Configure and install the Data Nodes
Install the data nodes, configure their network access, and define the disk layout for the cluster.
- Create data and archive volumes
Data volumes are used by the cluster to store database data, and archive volumes are used for storing backups.
- Create the Exasol database
Create and configure the database on a data volume and assign it database RAM for processing.
- Set up a backup schedule
Define a backup schedule for the database.
