Step 2 - Installing Postgres
============================

Installing Postgres
-------------------

You need to install Postgres on all the hosts.

An EDB account is required to use the `EDB Repos 2.0 <https://www.enterprisedb.com/repos>`_  page where you can
get installation instructions. Select your platform and Postgres
edition. You’re presented with 2 steps of instructions. The first step
covers how to configure the required package repository. The second step
covers how to install the packages from that repository.

Run both steps.

Worked example
--------------

This example installs EDB Postgres Advanced Server 16 on Red Hat
Enterprise Linux 9 (RHEL 9).

EDB account
^^^^^^^^^^^

You need an EDB account to install both Postgres and PGD.

Use your EDB account to sign in to the `EDB Repos 2.0 <https://www.enterprisedb.com/repos>`_  page where you can
select your platform. Then scroll down the list to select the Postgres
version you want to install:

-  EDB Postgres Advanced Server

-  EDB Postgres Extended

-  PostgreSQL

When you select the version of the Postgres server you want, two steps
are displayed.

1: Configuring repositories
^^^^^^^^^^^^^^^^^^^^^^^^^^^

For step 1, you can choose to use the automated script or step through
the manual install instructions that are displayed. Your EDB repository
token is inserted into these scripts by the EDB Repos 2.0 site. In the
examples, it’s shown as ``XXXXXXXXXXXXXXXX`` .

On each provisioned host, you either run the automatic repository
installation script or use the manual installation steps. The automatic
script looks like this:

.. code:: shell

   curl -1sLf https://downloads.enterprisedb.com/XXXXXXXXXXXXXXXX/enterprise/setup.rpm.sh | sudo -E bash

The manual installation steps look like this:

.. code:: shell

   dnf install yum-utils 
   rpm --import https://downloads.enterprisedb.com/XXXXXXXXXXXXXXXX/enterprise/gpg.E71EB0829F1EF813.key
   curl -1sLf https://downloads.enterprisedb.com/XXXXXXXXXXXXXXXX/enterprise/config.rpm.txt?distro=el&codename=9 > /tmp/enterprise.repo
   dnf config-manager --add-repo /tmp/enterprise.repo
   dnf -q makecache -y --disablerepo=* --enablerepo=enterprisedb-enterprise

2: Install Postgres
^^^^^^^^^^^^^^^^^^^

For step 2, run the command to install the packages:

::

   sudo dnf -y install edb-as16-server
