Installing PhotoPrism on Debian
Background
What is PhotoPrism?
PhotoPrism is a self-hosted web application for managing and organising a photo collection. It aims to provide many of the popular features of cloud services like Google Photos.
Why this guide?
The PhotoPrism documentation only covers Docker as an officially supported installation method. However, not everyone can, or wants to, use Docker. The only guide that covers installation without Docker is focused on development, and includes steps that are not necessary when one simply wants to run PhotoPrism.
The purpose of this guide, therefore, is to provide instructions for setting up a usable PhotoPrism installation on Debian. The guide has been written for, and tested on, Debian 11 "Bullseye", but should also work on older versions like Debian 10 "Buster", as well as derivatives like Ubuntu and Raspbian.
DISCLAIMER
This guide is provided in good faith and for informational purposes only. No claims are made or guarantees given that it will work on any particular combination of hardware and software, or that it will be kept up-to-date with new releases of PhotoPrism. You will assume all responsibility for managing your PhotoPrism server, including the prevention of unauthorised access and safeguards against data loss.
Installing PhotoPrism
Prerequisites
If you haven't done so already, ensure your server's packages are up-to-date:
$ sudo apt update
$ sudo apt upgrade
Next, a few packages need to be installed, these are mostly various helpers for installing PhotoPrism:
$ sudo apt install -y gcc g++ git gnupg make zip unzip
Node.js
While Node.js is available in Debian (and Ubuntu) repos, the version there is pretty old. Nodesource provides up-to-date versions. The latest LTS version as of the writing of this is v16, so install that:
$ wget https://deb.nodesource.com/setup_16.x -O node_setup.sh
$ chmod +x node_setup.sh
$ sudo ./node_setup.sh
$ sudo apt update
$ sudo apt install -y nodejs
Golang
Golang needs to be downloaded and installed manually. The latest version as of the writing of this is 1.17.7, but check the website and change the URLs below if necessary:
$ wget https://golang.org/dl/go1.17.7.linux-amd64.tar.gz
$ sudo tar -C /usr/local -xzf go1.17.7.linux-amd64.tar.gz
$ sudo ln -s /usr/local/go/bin/go /usr/local/bin/go
This downloads and extracts Golang to /usr/local/go, and creates a symlink to the go binary in /usr/local/bin (so it's in the $PATH).
Tensorflow
Tensorflow is an AI library developed by Google. PhotoPrism uses it to classify photos and detect faces. The necessary version (1.15, as of the writing of this) can be downloaded from the PhotoPrism website.
Choose the appropriate Tensorflow build based on whether your CPU supports the AVX or AVX2 instruction sets. You can check by running lscpu | grep --color avx.
If you have a reasonably recent CPU, you'll want the "avx2" version:
$ wget https://dl.photoprism.org/tensorflow/linux/libtensorflow-linux-avx2-1.15.2.tar.gz
$ sudo tar -C /usr/local -xzf libtensorflow-linux-avx2-1.15.2.tar.gz
$ sudo ldconfig
For older CPUs, use the "avx" version:
$ wget https://dl.photoprism.org/tensorflow/linux/libtensorflow-linux-avx-1.15.2.tar.gz
$ sudo tar -C /usr/local -xzf libtensorflow-linux-avx-1.15.2.tar.gz
$ sudo ldconfig
If your CPU supports neither instruction set, use the "cpu" version:
$ wget https://dl.photoprism.org/tensorflow/linux/libtensorflow-linux-cpu-1.15.2.tar.gz
$ sudo tar -C /usr/local -xzf libtensorflow-linux-cpu-1.15.2.tar.gz
$ sudo ldconfig
If an unsupported version is chosen, the PhotoPrism service will fail to start with an "Illegal operation" error. To repair, just run the above steps again with the corrected archive path.
See https://dl.photoprism.org/tensorflow for download URLs for other platforms (like ARM).
System setup
Instead of running PhotoPrism as root or your own user, it is advisable to create a separate user account for it:
$ sudo useradd --system -m -d /opt/photoprism -s /bin/bash photoprism
This will assume that all PhotoPrism-related files go to /opt/photoprism. If you would like to use another location, change it in the above and following commands.
Optional: storage directory
If you want to use a separate location for files like metadata, thumbnails, database (if using SQLite) and so on, create it now:
$ sudo mkdir /var/lib/photoprism
$ sudo chown photoprism:photoprism /var/lib/photoprism
Change the name of the directory to whatever you prefer to use.
Download and install PhotoPrism
Now switch to the newly-added user account and download the PhotoPrism source code:
$ sudo -u photoprism -i
$ git clone https://github.com/photoprism/photoprism.git src
Change to the src directory and run the following commands to install PhotoPrism:
$ cd src
$ make dep
$ make build-js
$ make install
The first command downloads the various dependencies for Tensorflow, the Node.js front-end and the Golang back-end. The second command builds the front-end. The third command builds the PhotoPrism production binary, copies it to ~/.local/bin/photoprism, and copies the front-end assets to ~/.photoprism/assets.
Building the front-end can take more than 1 GB of RAM, and the build might crash with Javascript running out of memory. If using a virtual machine, allocate at least 2 GB. Alternatively, you can try limiting Node's memory usage as follows (adjust the number based on available RAM on your system):
$ NODE_OPTIONS=--max_old_space_size=1024 make build-js
Check the Makefile for all make targets.
Configure PhotoPrism:
Go up a directory, to /opt/photoprism, and create a file for PhotoPrism configuration parameters:
$ cd ..
$ nano .env
This opens the file in the Nano text editor. Feel free to use another editor if you have a preference, but this guide will assume Nano.
The full list of configuration options is available here, but you can use the following as a starting point:
# Initial password for the admin user
PHOTOPRISM_ADMIN_PASSWORD="photoprism"
# Locations for the Import and Originals directories
# Best to keep these on redundant storage
PHOTOPRISM_ORIGINALS_PATH="/mnt/photos/Originals"
PHOTOPRISM_IMPORT_PATH="/mnt/photos/Import"
# PhotoPrism storage directory, if you set it up above
PHOTOPRISM_STORAGE_PATH="/var/lib/photoprism"
# Uncomment below if using MariaDB/MySQL instead of SQLite (the default)
# PHOTOPRISM_DATABASE_DRIVER="mysql"
# PHOTOPRISM_DATABASE_SERVER="MYSQL_IP_HERE"
# PHOTOPRISM_DATABASE_NAME="DB_NAME"
# PHOTOPRISM_DATABASE_USER="USER_NAME"
# PHOTOPRISM_DATABASE_PASSWORD="PASSWORD"
Press Ctrl+O and Enter to save, then Ctrl+X to exit Nano. Now enter the following command:
$ chmod 640 .env
This ensures that the file cannot be read by other users on the system, as it contains sensitive details.
The last step is setting up a system service so PhotoPrism can run automatically in the background.
System service
There's nothing else to do as the PhotoPrism user, so type exit to switch back to your own user account. Then create a file for the service definition:
$ sudo nano /etc/systemd/system/photoprism.service
Add the following contents:
[Unit]
Description=PhotoPrism service
After=network.target
[Service]
Type=forking
User=photoprism
Group=photoprism
WorkingDirectory=/opt/photoprism
EnvironmentFile=/opt/photoprism/.env
ExecStart=/opt/photoprism/.local/bin/photoprism up -d
ExecStop=/opt/photoprism/.local/bin/photoprism down
[Install]
WantedBy=multi-user.target
Now run the following commands to start the service and to have it start automatically on every boot:
$ sudo systemctl daemon-reload
$ sudo systemctl start photoprism
$ sudo systemctl enable photoprism
If all went well, you should be able to open http://YOUR-IP-HERE:2342 in a web browser and see the PhotoPrism interface. Log in as "admin" with the password set in the .env file.
Troubleshooting
Run the following command to check the service status:
$ systemctl status photoprism
