Arvados requires at least version *9.4* of PostgreSQL. We recommend using version 10 or newer.
* "AWS":#aws
* "CentOS 7":#centos7
* "Debian or Ubuntu":#debian
h3(#aws). AWS
When deploying on AWS, Arvados can use an Aurora RDS PostgreSQL database. Aurora Serverless is not recommended.
h3(#centos7). CentOS 7

# Install PostgreSQL
# yum install rh-postgresql12 rh-postgresql12-postgresql-contrib
~$ scl enable rh-postgresql12 bash
# Initialize the database
# postgresql-setup initdb
# Configure the database to accept password connections from localhost
# sed -ri -e 's/^(host +all +all +(127\.0\.0\.1\/32|::1\/128) +)ident$/\1md5/' /var/lib/pgsql/data/pg_hba.conf
# Configure the database to accept password connections from the local network (replace @10.9.8.0/24@ with your private network mask)
# echo 'host all all 10.9.8.0/24 md5' | tee -a /var/lib/pgsql/data/pg_hba.conf
# Configure the database to launch at boot and start now
# systemctl enable --now rh-postgresql12-postgresql
h3(#debian). Debian or Ubuntu
Debian 10 (Buster) and Ubuntu 16.04 (Xenial) and later versions include a sufficiently recent version of Postgres.
# Install PostgreSQL
# apt-get --no-install-recommends install postgresql postgresql-contrib
