Install PostgreSQL 9.4+

Arvados requires at least version 9.4 of PostgreSQL. We recommend using version 10 or newer.


When deploying on AWS, Arvados can use an Aurora RDS PostgreSQL database. Aurora Serverless is not recommended.

CentOS 7


On CentOS 7 and RHEL 7, these packages require a more recent version from Software Collections. The Software Collection will be installed automatically as long as Software Collections are enabled on your system.

To enable Software Collections on CentOS, run:

~$ sudo yum install centos-release-scl scl-utils

To enable Software Collections on RHEL:

~$ sudo yum-config-manager --enable rhel-server-rhscl-7-rpms

  1. Install PostgreSQL
    # yum install rh-postgresql12 rh-postgresql12-postgresql-contrib
    ~$ scl enable rh-postgresql12 bash
  2. Initialize the database
    # postgresql-setup initdb
  3. Configure the database to accept password connections
    # sed -ri -e 's/^(host +all +all +(127\.0\.0\.1\/32|::1\/128) +)ident$/\1md5/' /var/lib/pgsql/data/pg_hba.conf
  4. Configure the database to launch at boot and start now
    # systemctl enable --now rh-postgresql12-postgresql

Debian or Ubuntu

Debian 10 (Buster) and Ubuntu 16.04 (Xenial) and later versions include a sufficiently recent version of Postgres.

  1. Install PostgreSQL
    # apt-get --no-install-recommends install postgresql postgresql-contrib
  2. Configure the database to launch at boot and start now
    # systemctl enable --now postgresql
