Configuration: Postgre SQL set up for AVIX Server

PostgreSQL Setup for AVIX Server

This document guides IT administrators through setting up a dedicated PostgreSQL database instance for use with AVIX Server.

Overview & Prerequisites

Before configuring AVIX Server, the database engine must be installed, configured for network connectivity, and populated with the target database schema/owner.

Parameter Configuration Property in repositories.xml Example Value
Host Address serverHost

localhost or 192.168.1.50
Port portNumber

5432
Database Name databaseName

avix1
Database User databaseUser

postgres (or dedicated avix_user)

Password databasePassword

<your-secure-password>
SSL Connection useSSL

false or true

1. Engine Installation

Windows

  1. Download the official PostgreSQL Interactive Installer from EDB (see https://www.postgresql.org/download/windows/  and https://www.enterprisedb.com/downloads/postgres-postgresql-downloads )

  2. Run the executable and accept default paths

  3. Select PostgreSQL Server, pgAdmin 4, and Command Line Tools.

  4. Specify a master password for the postgres superuser during setup.

    2. Take note of your created password!

  5. Specify the port of the Postgres server:

Linux (Ubuntu / Debian)

Bash 
sudo apt update
sudo apt install -y postgresql postgresql-contrib

Linux (RHEL / Rocky / Fedora)

Bash 
sudo dnf install -y postgresql-server postgresql-contrib
sudo postgresql-setup --initdb
sudo systemctl enable --now postgresql

2. Network & Authentication Configuration

By default, PostgreSQL only accepts connections on localhost. Perform these steps if AVIX Server runs on a separate machine:

Edit postgresql.conf

  • Windows Location: C:\Program Files\PostgreSQL\<version>\data\postgresql.conf

  • Linux Location: /etc/postgresql/<version>/main/postgresql.conf (Debian/Ubuntu) or /var/lib/pgsql/data/postgresql.conf (RHEL)

Set the listen address and verify the port:

Ini, TOML 
listen_addresses = '*'
port = 5432

Edit pg_hba.conf

In the same data directory, add an authorization rule for the AVIX Server host IP:

Plaintext 
# TYPE  DATABASE        USER            ADDRESS                 METHOD
host    all             all             <AVIX_SERVER_IP>/32     scram-sha-256

Restart Service & Firewall

  • Windows: Restart postgresql-x64-<version> via services.msc and allow TCP port 5432 in Windows Defender Firewall.

  • Linux:

    Bash 
    sudo systemctl restart postgresql

# Firewall (Ubuntu UFW)
sudo ufw allow 5432/tcp

# Firewall (RHEL firewalld)
sudo firewall-cmd --add-port=5432/tcp --permanent && sudo firewall-cmd --reload

3. Database & User Creation

Log into psql using the postgres administrator account:

Bash 
# Linux
sudo -i -u postgres psql

# Windows (SQL Shell / CMD)
psql -U postgres

Execute the following SQL commands to prepare the environment:

SQL 
-- 1. Create dedicated user (optional if using default 'postgres')
CREATE USER postgres WITH PASSWORD 'postgres';

-- 2. Create the target database
CREATE DATABASE avix1 OWNER postgres;

-- 3. Grant full privileges to the database
GRANT ALL PRIVILEGES ON DATABASE avix1 TO postgres;

4. Verification & AVIX repositories.xml Integration

Connection Verification

Test connection from the machine hosting AVIX Server prior to service launch:

Bash 
psql -h <serverHost> -p 5432 -U postgres -d avix1

XML Configuration

Update repositories.xml on the AVIX Server host to reflect the database parameters:

XML 
<repositoryConfig>
    <repository name="repo1" 
                type="se.solme.avix.server.cdo.postgresql"
                serverHost="localhost"
                portNumber="5432"
                databaseName="avix1"
                databaseUser="postgres"
                databasePassword="postgres"
                useSSL="false"/>
</repositoryConfig>
```[cite: 1]

> **Note:** For production deployments, change default passwords and set `useSSL="true"`[cite: 1] along with configured TLS certificates on the PostgreSQL host.
