Install PostgreSQL for Linux
Overview
You can install an official PostgreSQL installation:
- either direct on your Linux server
- or via a Docker image.
See the installation instructions below.
When installing CAST Imaging on Linux via Docker, CAST provides a database instance as a Docker image - see What the the database requirements?. 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.
Supported PostgreSQL releases
See What are the database requirements?
Installation
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?). CAST recommends PostgreSQL 18.x. You can 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.
