## Installation
You can go multiple routes to setup and run Paperless:
[Use the easy install docker script](#docker_script)
[Pull the image from Docker Hub](#docker_hub)
[Build the Docker image yourself](#docker_build)
[Install Paperless directly on your system manually (bare metal)](#bare_metal)
The Docker routes are quick & easy. These are the recommended routes. This configures all the stuff from the above automatically so that it just works and uses sensible defaults for all configuration options. Here you find a cheat-sheet for docker beginners: [CLI Basics](https://www.sehn.tech/refs/devops-with-docker/)
The bare metal route is complicated to setup but makes it easier should you want to contribute some code back. You need to configure and run the above mentioned components yourself.
### Docker using the Installation Script {#docker_script}
Paperless provides an interactive installation script. This script will ask you for a couple configuration options, download and create the necessary configuration files, pull the docker image, start paperless and create your user account. This script essentially performs all the steps described in [Docker setup](#docker_hub) automatically.
Make sure that docker and docker-compose are installed.
Download and run the installation script:
`shell-session $ bash -c "$(curl -L https://raw.githubusercontent.com/paperless-ngx/paperless-ngx/main/install-paperless-ngx.sh)" `
### From GHCR / Docker Hub {#docker_hub}
Login with your user and create a folder in your home-directory to have a place for your configuration files and consumption directory.
`shell-session $ mkdir -v ~/paperless-ngx `Go to the [/docker/compose directory on the project page](https://github.com/paperless-ngx/paperless-ngx/tree/main/docker/compose) and download one of the docker-compose.*.yml files, depending on which database backend you want to use. Rename this file to docker-compose.yml. If you want to enable optional support for Office documents, download a file with -tika in the file name. Download the docker-compose.env file and the .env file as well and store them in the same directory.
!!! tip
For new installations, it is recommended to use PostgreSQL as the database backend.
Install [Docker](https://www.docker.com/) and [docker-compose](https://docs.docker.com/compose/install/).
!!! warning
If you want to use the included docker-compose.*.yml file, you need to have at least Docker version 17.09.0 and docker-compose version 1.17.0. To check do: docker-compose -v or docker -v
See the [Docker installation guide](https://docs.docker.com/engine/install/) on how to install the current version of Docker for your operating system or Linux distribution of choice. To get the latest version of docker-compose, follow the [docker-compose installation guide](https://docs.docker.com/compose/install/linux/) if your package repository doesn’t include it.
Modify docker-compose.yml to your preferences. You may want to change the path to the consumption directory. Find the line that specifies where to mount the consumption directory:
`yaml - ./consume:/usr/src/paperless/consume `Replace the part BEFORE the colon with a local directory of your choice:
`yaml - /home/jonaswinkler/paperless-inbox:/usr/src/paperless/consume `Don’t change the part after the colon or paperless wont find your documents.
You may also need to change the default port that the webserver will use from the default (8000):
8000:8000
Replace the part BEFORE the colon with a port of your choice:
8010:8000
Don’t change the part after the colon or edit other lines that refer to port 8000. Modifying the part before the colon will map requests on another port to the webserver running on the default port.
Rootless
If you want to run Paperless as a rootless container, you will need to do the following in your docker-compose.yml:
set the user running the container to map to the paperless user in the container. This value (user_id below), should be the same id that USERMAP_UID and USERMAP_GID are set to in the next step. See USERMAP_UID and USERMAP_GID [here](/configuration#docker).
Your entry for Paperless should contain something like:
>
` > webserver: > image: ghcr.io/paperless-ngx/paperless-ngx:latest > user: <user_id> > `Modify docker-compose.env, following the comments in the file. The most important change is to set USERMAP_UID and USERMAP_GID to the uid and gid of your user on the host system. Use id -u and id -g to get these.
This ensures that both the docker container and you on the host machine have write access to the consumption directory. If your UID and GID on the host system is 1000 (the default for the first normal user on most systems), it will work out of the box without any modifications. id “username” to check.
!!! note
You can copy any setting from the file paperless.conf.example and paste it here. Have a look at [configuration](/configuration) to see what’s available.
!!! note
You can utilize Docker secrets for configuration settings by appending _FILE to configuration values. For example PAPERLESS_DBUSER can be set using PAPERLESS_DBUSER_FILE=/var/run/secrets/password.txt.
!!! warning
Some file systems such as NFS network shares don’t support file system notifications with inotify. When storing the consumption directory on such a file system, paperless will not pick up new files with the default configuration. You will need to use PAPERLESS_CONSUMER_POLLING, which will disable inotify. See [here](/configuration#polling).
Run docker-compose pull. This will pull the image.
To be able to login, you will need a super user. To create it, execute the following command:
`shell-session $ docker-compose run --rm webserver createsuperuser `This will prompt you to set a username, an optional e-mail address and finally a password (at least 8 characters).
Run docker-compose up -d. This will create and start the necessary containers.
The default docker-compose.yml exports the webserver on your local port
8000. If you did not change this, you should now be able to visit your Paperless instance at http://127.0.0.1:8000 or your servers IP-Address:8000. Use the login credentials you have created with the previous step.
### Build the Docker image yourself {#docker_build}
Clone the entire repository of paperless:
`shell-session git clone https://github.com/paperless-ngx/paperless-ngx `The main branch always reflects the latest stable version.
Copy one of the docker/compose/docker-compose.*.yml to docker-compose.yml in the root folder, depending on which database backend you want to use. Copy docker-compose.env into the project root as well.
In the docker-compose.yml file, find the line that instructs docker-compose to pull the paperless image from Docker Hub:
image: ghcr.io/paperless-ngx/paperless-ngx:latest
and replace it with a line that instructs docker-compose to build the image from the current working directory instead:
- build:
context: . args:
QPDF_VERSION: x.y.x PIKEPDF_VERSION: x.y.z PSYCOPG2_VERSION: x.y.z JBIG2ENC_VERSION: 0.29
!!! note
You should match the build argument versions to the version for the release you have checked out. These are pre-built images with certain, more updated software. If you want to build these images your self, that is possible, but beyond the scope of these steps.
Follow steps 3 to 8 of [Docker Setup](#docker_hub). When asked to run docker-compose pull to pull the image, do
`shell-session $ docker-compose build `instead to build the image.
### Bare Metal Route {#bare_metal}
Paperless runs on linux only. The following procedure has been tested on a minimal installation of Debian/Buster, which is the current stable release at the time of writing. Windows is not and will never be supported.
Install dependencies. Paperless requires the following packages.
python3 3.8, 3.9
python3-pip
python3-dev
default-libmysqlclient-dev for MariaDB
fonts-liberation for generating thumbnails for plain text files
imagemagick >= 6 for PDF conversion
gnupg for handling encrypted documents
libpq-dev for PostgreSQL
libmagic-dev for mime type detection
mariadb-client for MariaDB compile time
mime-support for mime type detection
libzbar0 for barcode detection
poppler-utils for barcode detection
Use this list for your preferred package management:
` python3 python3-pip python3-dev imagemagick fonts-liberation gnupg libpq-dev default-libmysqlclient-dev libmagic-dev mime-support libzbar0 poppler-utils `These dependencies are required for OCRmyPDF, which is used for text recognition.
unpaper
ghostscript
icc-profiles-free
qpdf
liblept5
libxml2
pngquant (suggested for certain PDF image optimizations)
zlib1g
tesseract-ocr >= 4.0.0 for OCR
tesseract-ocr language packs (tesseract-ocr-eng, tesseract-ocr-deu, etc)
Use this list for your preferred package management:
` unpaper ghostscript icc-profiles-free qpdf liblept5 libxml2 pngquant zlib1g tesseract-ocr `On Raspberry Pi, these libraries are required as well:
libatlas-base-dev
libxslt1-dev
You will also need build-essential, python3-setuptools and python3-wheel for installing some of the python dependencies.
Install redis >= 6.0 and configure it to start automatically.
Optional. Install postgresql and configure a database, user and password for paperless. If you do not wish to use PostgreSQL, MariaDB and SQLite are available as well.
!!! note
On bare-metal installations using SQLite, ensure the [JSON1 extension](https://code.djangoproject.com/wiki/JSON1Extension) is enabled. This is usually the case, but not always.
Create a system user with a new home folder under which you wish to run paperless.
`shell-session adduser paperless --system --home /opt/paperless --group `Get the release archive from <https://github.com/paperless-ngx/paperless-ngx/releases> for example with
`shell-session curl -O -L https://github.com/paperless-ngx/paperless-ngx/releases/download/v1.10.2/paperless-ngx-v1.10.2.tar.xz `Extract the archive with
`shell-session tar -xf paperless-ngx-v1.10.2.tar.xz `and copy the contents to the home folder of the user you created before (/opt/paperless).
Optional: If you cloned the git repo, you will have to compile the frontend yourself, see [here](/development#front-end-development) and use the build step, not serve.
Configure paperless. See [configuration](/configuration) for details. Edit the included paperless.conf and adjust the settings to your needs. Required settings for getting paperless running are:
PAPERLESS_REDIS should point to your redis server, such as <redis://localhost:6379>.
PAPERLESS_DBENGINE optional, and should be one of postgres, mariadb, or sqlite
PAPERLESS_DBHOST should be the hostname on which your PostgreSQL server is running. Do not configure this to use SQLite instead. Also configure port, database name, user and password as necessary.
PAPERLESS_CONSUMPTION_DIR should point to a folder which paperless should watch for documents. You might want to have this somewhere else. Likewise, PAPERLESS_DATA_DIR and PAPERLESS_MEDIA_ROOT define where paperless stores its data. If you like, you can point both to the same directory.
PAPERLESS_SECRET_KEY should be a random sequence of characters. It’s used for authentication. Failure to do so allows third parties to forge authentication credentials.
PAPERLESS_URL if you are behind a reverse proxy. This should point to your domain. Please see [configuration](/configuration) for more information.
Many more adjustments can be made to paperless, especially the OCR part. The following options are recommended for everyone:
Set PAPERLESS_OCR_LANGUAGE to the language most of your documents are written in.
Set PAPERLESS_TIME_ZONE to your local time zone.
!!! warning
Ensure your Redis instance [is secured](https://redis.io/docs/getting-started/#securing-redis).
Create the following directories if they are missing:
/opt/paperless/media
/opt/paperless/data
/opt/paperless/consume
Adjust as necessary if you configured different folders. Ensure that the paperless user has write permissions for every one of these folders with
`shell-session ls -l -d /opt/paperless/media `If needed, change the owner with
`shell-session sudo chown paperless:paperless /opt/paperless/media sudo chown paperless:paperless /opt/paperless/data sudo chown paperless:paperless /opt/paperless/consume `Install python requirements from the requirements.txt file. It is up to you if you wish to use a virtual environment or not. First you should update your pip, so it gets the actual packages.
`shell-session sudo -Hu paperless pip3 install -r requirements.txt `This will install all python dependencies in the home directory of the new paperless user.
Go to /opt/paperless/src, and execute the following commands:
```bash # This creates the database schema. sudo -Hu paperless python3 manage.py migrate
# This creates your first paperless user sudo -Hu paperless python3 manage.py createsuperuser ```
Optional: Test that paperless is working by executing
`bash # Manually starts the webserver sudo -Hu paperless python3 manage.py runserver `and pointing your browser to http://localhost:8000 if accessing from the same devices on which paperless is installed. If accessing from another machine, set up systemd services. You may need to set PAPERLESS_DEBUG=true in order for the development server to work normally in your browser.
!!! warning
This is a development server which should not be used in production. It is not audited for security and performance is inferior to production ready web servers.
!!! tip
This will not start the consumer. Paperless does this in a separate process.
Setup systemd services to run paperless automatically. You may use the service definition files included in the scripts folder as a starting point.
Paperless needs the webserver script to run the webserver, the consumer script to watch the input folder, taskqueue for the background workers used to handle things like document consumption and the scheduler script to run tasks such as email checking at certain times .
!!! note
The socket script enables gunicorn to run on port 80 without root privileges. For this you need to uncomment the Require=paperless-webserver.socket in the webserver script and configure gunicorn to listen on port 80 (see paperless/gunicorn.conf.py).
You may need to adjust the path to the gunicorn executable. This will be installed as part of the python dependencies, and is either located in the bin folder of your virtual environment, or in ~/.local/bin/ if no virtual environment is used.
These services rely on redis and optionally the database server, but don’t need to be started in any particular order. The example files depend on redis being started. If you use a database server, you should add additional dependencies.
!!! warning
The included scripts run a gunicorn standalone server, which is fine for running paperless. It does support SSL, however, the documentation of GUnicorn states that you should use a proxy server in front of gunicorn instead.
For instructions on how to use nginx for that, [see the instructions below](/setup#nginx).
!!! warning
If celery won’t start (check with sudo systemctl status paperless-task-queue.service for paperless-task-queue.service and paperless-scheduler.service ) you need to change the path in the files. Example: ExecStart=/opt/paperless/.local/bin/celery –app paperless worker –loglevel INFO
Optional: Install a samba server and make the consumption folder available as a network share.
Configure ImageMagick to allow processing of PDF documents. Most distributions have this disabled by default, since PDF documents can contain malware. If you don’t do this, paperless will fall back to ghostscript for certain steps such as thumbnail generation.
Edit /etc/ImageMagick-6/policy.xml and adjust
` <policy domain="coder" rights="none" pattern="PDF" /> `to
` <policy domain="coder" rights="read|write" pattern="PDF" /> `Optional: Install the [jbig2enc](https://ocrmypdf.readthedocs.io/en/latest/jbig2.html) encoder. This will reduce the size of generated PDF documents. You’ll most likely need to compile this by yourself, because this software has been patented until around 2017 and binary packages are not available for most distributions.
Optional: If using the NLTK machine learning processing (see PAPERLESS_ENABLE_NLTK in [configuration](/configuration#software_tweaks) for details), download the NLTK data for the Snowball Stemmer, Stopwords and Punkt tokenizer to your PAPERLESS_DATA_DIR/nltk. Refer to the [NLTK instructions](https://www.nltk.org/data.html) for details on how to download the data.
# Migrating to Paperless-ngx
Migration is possible both from Paperless-ng or directly from the ‘original’ Paperless.
## Migrating from Paperless-ng
Paperless-ngx is meant to be a drop-in replacement for Paperless-ng and thus upgrading should be trivial for most users, especially when using docker. However, as with any major change, it is recommended to take a full backup first. Once you are ready, simply change the docker image to point to the new source. E.g. if using Docker Compose, edit docker-compose.yml and change:
`
image: jonaswinkler/paperless-ng:latest
`
to
`
image: ghcr.io/paperless-ngx/paperless-ngx:latest
`
and then run docker-compose up -d which will pull the new image recreate the container. That’s it!
Users who installed with the bare-metal route should also update their Git clone to point to https://github.com/paperless-ngx/paperless-ngx, e.g. using the command git remote set-url origin https://github.com/paperless-ngx/paperless-ngx and then pull the lastest version.
## Migrating from Paperless
At its core, paperless-ngx is still paperless and fully compatible. However, some things have changed under the hood, so you need to adapt your setup depending on how you installed paperless.
This setup describes how to update an existing paperless Docker installation. The important things to keep in mind are as follows:
Read the [changelog](/changelog) and take note of breaking changes.
You should decide if you want to stick with SQLite or want to migrate your database to PostgreSQL. See [documentation](#sqlite_to_psql) for details on how to move your data from SQLite to PostgreSQL. Both work fine with paperless. However, if you already have a database server running for other services, you might as well use it for paperless as well.
The task scheduler of paperless, which is used to execute periodic tasks such as email checking and maintenance, requires a [redis](https://redis.io/) message broker instance. The docker-compose route takes care of that.
The layout of the folder structure for your documents and data remains the same, so you can just plug your old docker volumes into paperless-ngx and expect it to find everything where it should be.
Migration to paperless-ngx is then performed in a few simple steps:
Stop paperless.
`bash $ cd /path/to/current/paperless $ docker-compose down `Do a backup for two purposes: If something goes wrong, you still have your data. Second, if you don’t like paperless-ngx, you can switch back to paperless.
Download the latest release of paperless-ngx. You can either go with the docker-compose files from [here](https://github.com/paperless-ngx/paperless-ngx/tree/main/docker/compose) or clone the repository to build the image yourself (see [above](#docker_build)). You can either replace your current paperless folder or put paperless-ngx in a different location.
!!! warning
Paperless-ngx includes a .env file. This will set the project name for docker compose to paperless, which will also define the name of the volumes by paperless-ngx. However, if you experience that paperless-ngx is not using your old paperless volumes, verify the names of your volumes with
` shell-session $ docker volume ls | grep _data `and adjust the project name in the .env file so that it matches the name of the volumes before the _data part.
Download the docker-compose.sqlite.yml file to docker-compose.yml. If you want to switch to PostgreSQL, do that after you migrated your existing SQLite database.
Adjust docker-compose.yml and docker-compose.env to your needs. See [Docker setup](#docker_hub) details on which edits are advised.
[Update paperless.](/administration#updating)
In order to find your existing documents with the new search feature, you need to invoke a one-time operation that will create the search index:
`shell-session $ docker-compose run --rm webserver document_index reindex `This will migrate your database and create the search index. After that, paperless will take care of maintaining the index by itself.
Start paperless-ngx.
`bash $ docker-compose up -d `This will run paperless in the background and automatically start it on system boot.
Paperless installed a permanent redirect to admin/ in your browser. This redirect is still in place and prevents access to the new UI. Clear your browsing cache in order to fix this.
Optionally, follow the instructions below to migrate your existing data to PostgreSQL.
## Migrating from LinuxServer.io Docker Image
As with any upgrades and large changes, it is highly recommended to create a backup before starting. This assumes the image was running using Docker Compose, but the instructions are translatable to Docker commands as well.
Stop and remove the paperless container
If using an external database, stop the container
Update Redis configuration a) If REDIS_URL is already set, change it to PAPERLESS_REDIS and continue to step 4. b) Otherwise, in the docker-compose.yml add a new service for Redis, following [the example compose files](https://github.com/paperless-ngx/paperless-ngx/tree/main/docker/compose) c) Set the environment variable PAPERLESS_REDIS so it points to the new Redis container
Update user mapping a) If set, change the environment variable PUID to USERMAP_UID b) If set, change the environment variable PGID to USERMAP_GID
Update configuration paths a) Set the environment variable PAPERLESS_DATA_DIR to /config
Update media paths a) Set the environment variable PAPERLESS_MEDIA_ROOT to /data/media
Update timezone a) Set the environment variable PAPERLESS_TIME_ZONE to the same value as TZ
Modify the image: to point to ghcr.io/paperless-ngx/paperless-ngx:latest or a specific version if preferred.
Start the containers as before, using docker-compose.
## Moving data from SQLite to PostgreSQL or MySQL/MariaDB {#sqlite_to_psql}
Moving your data from SQLite to PostgreSQL or MySQL/MariaDB is done via executing a series of django management commands as below. The commands below use PostgreSQL, but are applicable to MySQL/MariaDB with the
!!! warning
Make sure that your SQLite database is migrated to the latest version. Starting paperless will make sure that this is the case. If your try to load data from an old database schema in SQLite into a newer database schema in PostgreSQL, you will run into trouble.
!!! warning
On some database fields, PostgreSQL enforces predefined limits on maximum length, whereas SQLite does not. The fields in question are the title of documents (128 characters), names of document types, tags and correspondents (128 characters), and filenames (1024 characters). If you have data in these fields that surpasses these limits, migration to PostgreSQL is not possible and will fail with an error.
!!! warning
MySQL is case insensitive by default, treating values like “Name” and “NAME” as identical. See [MySQL caveats](/advanced_usage#mysql-caveats) for details.
!!! warning
MySQL also enforces limits on maximum lengths, but does so differently than PostgreSQL. It may not be possible to migrate to MySQL due to this.
!!! warning
Using mariadb version 10.4+ is recommended. Using the utf8mb3 character set on an older system may fix issues that can arise while setting up Paperless-ngx but utf8mb3 can cause issues with consumption (where utf8mb4 does not).
Stop paperless, if it is running.
Tell paperless to use PostgreSQL:
a) With docker, copy the provided docker-compose.postgres.yml file to docker-compose.yml. Remember to adjust the consumption directory, if necessary. b) Without docker, configure the database in your paperless.conf file. See [configuration](/configuration) for details.
Open a shell and initialize the database:
a) With docker, run the following command to open a shell within the paperless container:
` shell-session $ cd /path/to/paperless $ docker-compose run --rm webserver /bin/bash `This will launch the container and initialize the PostgreSQL database.
b) Without docker, remember to activate any virtual environment, switch to the src directory and create the database schema:
` shell-session $ cd /path/to/paperless/src $ python3 manage.py migrate `This will not copy any data yet.
Dump your data from SQLite:
`shell-session $ python3 manage.py dumpdata --database=sqlite --exclude=contenttypes --exclude=auth.Permission > data.json `Load your data into PostgreSQL:
`shell-session $ python3 manage.py loaddata data.json `If operating inside Docker, you may exit the shell now.
`shell-session $ exit `Start paperless.
## Moving back to Paperless
Lets say you migrated to Paperless-ngx and used it for a while, but decided that you don’t like it and want to move back (If you do, send me a mail about what part you didn’t like!), you can totally do that with a few simple steps.
Paperless-ngx modified the database schema slightly, however, these changes can be reverted while keeping your current data, so that your current data will be compatible with original Paperless. Thumbnails were also changed from PNG to WEBP format and will need to be re-generated.
Execute this:
`shell-session
$ cd /path/to/paperless
$ docker-compose run --rm webserver migrate documents 0023
`
Or without docker:
`shell-session
$ cd /path/to/paperless/src
$ python3 manage.py migrate documents 0023
`
After regenerating thumbnails, you’ll need to clear your cookies (Paperless-ngx comes with updated dependencies that do cookie-processing differently) and probably your cache as well.
# Considerations for less powerful devices {#less-powerful-devices}
Paperless runs on Raspberry Pi. However, some things are rather slow on the Pi and configuring some options in paperless can help improve performance immensely:
Stick with SQLite to save some resources.
Consider setting PAPERLESS_OCR_PAGES to 1, so that paperless will only OCR the first page of your documents. In most cases, this page contains enough information to be able to find it.
PAPERLESS_TASK_WORKERS and PAPERLESS_THREADS_PER_WORKER are configured to use all cores. The Raspberry Pi models 3 and up have 4 cores, meaning that paperless will use 2 workers and 2 threads per worker. This may result in sluggish response times during consumption, so you might want to lower these settings (example: 2 workers and 1 thread to always have some computing power left for other tasks).
Keep PAPERLESS_OCR_MODE at its default value skip and consider OCR’ing your documents before feeding them into paperless. Some scanners are able to do this!
Set PAPERLESS_OCR_SKIP_ARCHIVE_FILE to with_text to skip archive file generation for already ocr’ed documents, or always to skip it for all documents.
If you want to perform OCR on the device, consider using PAPERLESS_OCR_CLEAN=none. This will speed up OCR times and use less memory at the expense of slightly worse OCR results.
If using docker, consider setting PAPERLESS_WEBSERVER_WORKERS to 1. This will save some memory.
Consider setting PAPERLESS_ENABLE_NLTK to false, to disable the more advanced language processing, which can take more memory and processing time.
For details, refer to [configuration](/configuration).
!!! note
Updating the [automatic matching algorithm](/advanced_usage#automatic-matching) takes quite a bit of time. However, the update mechanism checks if your data has changed before doing the heavy lifting. If you experience the algorithm taking too much cpu time, consider changing the schedule in the admin interface to daily. You can also manually invoke the task by changing the date and time of the next run to today/now.
The actual matching of the algorithm is fast and works on Raspberry Pi as well as on any other device.
# Using nginx as a reverse proxy {#nginx}
If you want to expose paperless to the internet, you should hide it behind a reverse proxy with SSL enabled.
In addition to the usual configuration for SSL, the following configuration is required for paperless to operate:
# Adjust as required. This is the maximum size for file uploads. # The default value 1M might be a little too small. client_max_body_size 10M;
server {
location / {
# Adjust host and port as required. proxy_pass http://localhost:8000/;
# These configuration options are required for WebSockets to work. proxy_http_version 1.1; proxy_set_header Upgrade $http_upgrade; proxy_set_header Connection “upgrade”;
proxy_redirect off; proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header X-Forwarded-Host $server_name; add_header P3P ‘CP=””’; # may not be required in all setups
}
}
}
The PAPERLESS_URL configuration variable is also required when using a reverse proxy. Please refer to the [hosting and security](/configuration#hosting-and-security) docs.
Also read [this](https://channels.readthedocs.io/en/stable/deploying.html#nginx-supervisor-ubuntu), towards the end of the section.
