Papermerge

Papermerge is an open source document management system for digital archives.

Installation

Install the papermerge^AUR package. Installation and updates of the package automatically run the database migrations.

Start

Enable and start the two papermerge systemd units:

# systemctl enable --now papermerge-gunicorn papermerge-worker

Your papermerge instance should now be available at port 9001.

Configuration

For details on papermerge configuration, visit its official documentation. The main configuration file is located at /etc/papermerge.conf.py.

Note: The papermerge^AUR package creates a papermerge system user and provides a papermerge-manage command which should always be run as the papermerge user. See below for an example. The papermerge-manage command should be used wherever the official documentation refers to manage.py.

Do not forget to restart papermerge-gunicorn.service and papermerge-worker.service after changing configurations.

Create admin user

After initial installation, you should create an admin user for your papermerge instance:

$ sudo -u papermerge papermerge-manage createsuperuser

Nginx

Install Nginx and use the following configuration as a starting point for the papermerge virtual host:

/etc/nginx/sites-available/papermerge.domain.tld

server {
    server_name papermerge.domain.tld;
    listen 80;
    listen [::]:80;

    location /static/ {
        alias /var/lib/papermerge/static/;
    }

    location /media/ {
        alias /var/lib/papermerge/media/;
    }

    location / {
        proxy_pass http://127.0.0.1:9001;
    }
}

Redis

It is recommended to use Redis as a message broker instead of the default filesystem-based approach.

Install redis and python-redis and start/enable redis.service. In /usr/lib/python3.9/site-packages/config/settings/base.py replace

/usr/lib/python3.9/site-packages/config/settings/base.py

CELERY_BROKER_URL = "filesystem://"
CELERY_BROKER_TRANSPORT_OPTIONS = {
    'data_folder_in': PAPERMERGE_TASK_QUEUE_DIR,
    'data_folder_out': PAPERMERGE_TASK_QUEUE_DIR,
}

with

/usr/lib/python3.9/site-packages/config/settings/base.py

CELERY_BROKER_URL = "redis://"
CELERY_BROKER_TRANSPORT_OPTIONS = {}
CELERY_RESULT_BACKEND = "redis://localhost/0"

and restart papermerge-gunicorn.service and papermerge-worker.service
