Install PostgreSQL for Linux

Overview

CAST does not provide a PostgreSQL installer for Linux environments, however, CAST recommends installing the equivalent PostgreSQL release on a Linux server to take advantage of the superior performance over CAST Storage Service installed on Microsoft Windows.

You can install an official PostgreSQL installation:

either direct on your Linux server
or via a Docker image.

See the instructions below.

When installing CAST Imaging on Linux via Docker, CAST provides a database instance as a Docker image. By default, this instance will be used by CAST Imaging for both analysis data and persistence data storage needs. However, you are free to install additional database instances, for example to separate the storage of persistence data and analysis data on two separate instances.

Instructions

Direct install on Linux server

Your chosen Linux distribution may include a specific release of PostgreSQL by default but that may not be the latest available release nor one that is supported by CAST (see What are the database requirements?). You can instead use the official PostgreSQL repository for your distribution’s package manager system to install the specific release you need:

Distribution	Instructions
Ubuntu via APT	https://www.postgresql.org/download/linux/ubuntu/
Debian via APT	https://www.postgresql.org/download/linux/debian/
Red Hat (RHEL/Rocky/Alma/CentOS) via Yum or DNF	https://www.postgresql.org/download/linux/redhat/

Install via a Docker image

See https://hub.docker.com/_/postgres for more information about how to install an official PostgreSQL image on Docker.
