PhotoPrism (AI-Powered Photo Manager) on AlmaLinux 9

PhotoPrism is an open-source, self-hosted AI-powered photo and video management platform built to organize, browse, and search large media libraries intelligently. By using built-in machine learning, PhotoPrism can automatically classify images, detect objects and scenes, recognize faces, and extract EXIF/GPS metadata, turning massive photo collections into a fast, searchable visual archive.

Unlike cloud-based photo services, PhotoPrism runs entirely on your own infrastructure. Your photos and videos never leave your server, making it an ideal solution for privacy-conscious users, photographers, home labs, and organizations that want modern AI features without giving up data ownership.

Running PhotoPrism on AlmaLinux 9, a RHEL-compatible, enterprise-grade Linux distribution, provides long-term stability, security updates, and predictable performance. AlmaLinux 9 is well suited for production workloads and pairs perfectly with Docker, PostgreSQL, Nginx, and HTTPS for a secure, scalable, and maintainable PhotoPrism deployment.

Architecture Overview

Layer	Component	Role
OS	AlmaLinux 9	Enterprise-grade, RHEL-compatible Linux base
Container Runtime	Docker / Docker Compose	Runs PhotoPrism and supporting services
Application	PhotoPrism (Go + TensorFlow Lite)	AI-powered photo and video management
Database	PostgreSQL	Stores metadata, search indexes, and user data
Storage	Local filesystem / NAS	Original photos and videos
Reverse Proxy	Nginx	HTTPS termination, routing, compression
TLS	Let’s Encrypt / PKI	Secure access to the PhotoPrism web interface

PhotoPrism scales well from small personal libraries to very large collections containing hundreds of thousands of photos, depending on available CPU, RAM, and storage performance.

Security & Best Practices on AlmaLinux 9

• Run PhotoPrism behind Nginx with HTTPS enabled.
• Keep PhotoPrism and PostgreSQL on internal Docker networks only.
• Store secrets (database passwords, admin credentials) using environment variables.
• Enable SELinux enforcing mode and use proper Docker volume labels.
• Configure firewalld to allow only ports 80 and 443.
• Automate SSL certificate renewal using Certbot or another ACME client.
• Regularly update AlmaLinux, Docker, and PhotoPrism images.
• Back up:
  • original photos and videos
  • PostgreSQL database
  • PhotoPrism configuration and index
• Mount original photo directories as read-only when possible.
• Create separate user roles and limit admin access.

---

Typical Use Cases

• Personal photo libraries – replace Google Photos or iCloud Photos
• Family media servers – shared albums with private hosting
• Photographers – manage large RAW and JPEG collections
• Home labs & NAS setups – centralized photo and video management
• Privacy-focused users – AI features without cloud tracking
• Small organizations – internal photo archives and media catalogs

Create an AlmaLinux 9 Instance on Shape.Host

Go to https://shape.host and log in

Click Create

Choose Instance

Select a server location

Choose AlmaLinux 9 (64-bit)

Pick a plan (recommended minimum for PhotoPrism):

2 vCPU

4 GB RAM (8 GB recommended for large photo libraries)

40 GB NVMe SSD or more

Click Create Instance

Copy the public IP address

---

Step 1: Connect to the Server via SSH

From your local machine:

ssh root@YOUR_SERVER_IP

You are now logged in as the root user.

---

Step 2: Update the System

dnf update

Updates all installed packages to the latest versions.

---

Step 3: Install Required System Packages

dnf install ca-certificates curl gnupg2 dnf-utils

These packages are required to securely add external repositories and download Docker components.

---

Step 4: Add Docker Repository

dnf config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo

Adds the official Docker repository compatible with AlmaLinux 9.

---

Step 5: Refresh Package Cache

dnf makecache

Loads metadata from the newly added Docker repository.

---

Step 6: Install Docker and Docker Compose

dnf install docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin

Installs Docker Engine and Docker Compose v2.

---

Step 7: Enable and Start Docker

systemctl enable docker
systemctl start docker

Ensures Docker starts automatically at boot.

---

Step 8: Verify Docker Installation

docker --version
docker compose version

Confirms Docker and Docker Compose are installed correctly.

---

Step 9: Create PhotoPrism Directory

mkdir -p /opt/photoprism
cd /opt/photoprism

This directory will store PhotoPrism configuration and data.

---

Step 10: Download PhotoPrism Docker Compose Template

wget https://dl.photoprism.app/docker/compose.yaml -O docker-compose.yml

Downloads the official PhotoPrism Docker Compose file.

---

Step 11: Edit Docker Compose Configuration

nano docker-compose.yml

Adjust the file as follows:

services:
  photoprism:
