Operating System
I chose CentOS 7 x64 with 1 CPU, 1GB RAM, 20GB HDD, which PostgreSQL should run fine on.
Package Installations
reference here: https://www.postgresql.org/download/linux/redhat/
I installed the following initial packages, going with Postgres 9.6 b/c that was the highest supported version for Confluence.
~$ sudo yum update && sudo yum upgrade -y ~$ sudo yum install -y vim https://download.postgresql.org/pub/repos/yum/9.6/redhat/rhel-7-x86_64/pgdg-centos96-9.6-3.noarch.rpm ~$ sudo yum install -y postgresql96 postgresql96-server
Initialize DB and enable autostart
~$ sudo /usr/pgsql-9.6/bin/postgresql96-setup initdb ~$ sudo systemctl enable postgresql-9.6 ~$ sudo systemctl start postgresql-9.6
Verify installation
~$ sudo -u postgres /usr/pgsql-9.6/bin/psql -c "SELECT version();"
