CryptPad: Essential Tips for Successful Self-Hosting
Table of Contents

CryptPad is an open-source, privacy-focused collaborative platform that enables users to create and share encrypted documents, spreadsheets, kanban boards, and more. Designed with end-to-end encryption, CryptPad ensures user data remains private and inaccessible to the server operator. Self-hosting CryptPad empowers users with full control over their data, customization options, and enhanced security. In this guide, we’ll cover how to install, configure, and manage CryptPad, ensuring a smooth and secure deployment tailored to your needs.

Installing CryptPad

📦 Docker/Docker Compose Setup

Docker is the most efficient way to run CryptPad with minimal dependency management. Below is a docker-compose.yml file configured for CryptPad:


version: '3.7'

services:

cryptpad:

image: cryptpad/cryptpad:latest

container_name: cryptpad

ports:

- "3000:3000"

volumes:

- cryptpad_data:/cryptpad/data

- cryptpad_custom:/cryptpad/customize

environment:

- NODE_ENV=production

restart: always

volumes:

cryptpad_data:

driver: local

cryptpad_custom:

driver: local

To deploy CryptPad using Docker Compose:


nano docker-compose.yml

## Start the CryptPad container

docker-compose up -d

## Verify CryptPad is running

docker ps

Access CryptPad on http://<your-server-ip>:3000.

🚀 Manual Installation

For those not using Docker, follow these steps to install CryptPad manually on a Linux server:

  1. Install Node.js, npm, and required dependencies:

sudo apt update

sudo apt install -y nodejs npm git build-essential

  1. Clone the CryptPad repository:

git clone https://github.com/xwiki-labs/cryptpad.git

cd cryptpad

  1. Install dependencies and build CryptPad:

npm install

npm run build

  1. Start CryptPad:

NODE_ENV=production node server.js

CryptPad will be accessible on http://<your-server-ip>:3000.

Configuring Nginx as a Reverse Proxy

🌐 Nginx Configuration

To serve CryptPad through Nginx, create an Nginx server block:


server {

listen 80;

server_name cryptpad.example.com;

location / {

proxy_pass http://localhost:3000;

proxy_http_version 1.1;

proxy_set_header Upgrade $http_upgrade;

proxy_set_header Connection 'upgrade';

proxy_set_header Host $host;

proxy_cache_bypass $http_upgrade;

}

}

Save the configuration as /etc/nginx/sites-available/cryptpad and enable it:


sudo ln -s /etc/nginx/sites-available/cryptpad /etc/nginx/sites-enabled/

sudo nginx -t

sudo systemctl reload nginx

🔒 SSL/TLS Setup

Secure CryptPad with Let's Encrypt:


sudo apt install -y certbot python3-certbot-nginx

sudo certbot --nginx -d cryptpad.example.com

Automate certificate renewal:


sudo systemctl enable certbot-renew.timer

sudo systemctl start certbot-renew.timer

🛠️ Testing and Reloading Nginx

After configuring Nginx, reload it and ensure the service is active:


sudo nginx -t

sudo systemctl reload nginx

Logging and Debugging CryptPad

🗃️ Enabling Debug Logs

Increase the log verbosity in config/config.json by setting logLevel to debug:


"logLevel": "debug"

Restart CryptPad to apply changes:


docker restart cryptpad  # if using Docker

## OR

pkill -f node && NODE_ENV=production node server.js  # manual setup

📄 Viewing Logs

View CryptPad logs directly:


## For Docker

docker logs cryptpad

## For manual setup

cat logs/cryptpad.log

🛠️ Troubleshooting Common Issues

Check for common errors like missing dependencies or port conflicts in the logs. For example:

  • Missing NODE_ENV=production: Ensure the environment variable is set before running the app.

  • Port conflicts: Use netstat -tuln | grep 3000 to identify conflicting services.

📤 Exporting Logs

Forward logs to an external system like ELK Stack:


docker logs cryptpad > /path/to/export/cryptpad.log

Backup and Restore

🗂️ File-Based Backups

Backup CryptPad’s data directory:


## For Docker

docker cp cryptpad:/cryptpad/data /backup/cryptpad_data

## For manual setup

tar -czvf cryptpad_backup.tar.gz /path/to/cryptpad/data

🔄 Database Backups

If CryptPad uses a database (e.g., for advanced configurations), export it:


mysqldump -u root -p cryptpad_db > cryptpad_db_backup.sql

📅 Automated Backup Scripts

Automate periodic backups with a cron job:


crontab -e

## Add the following line to schedule daily backups at 3 AM

0 3 * * * docker cp cryptpad:/cryptpad/data /backup/cryptpad_data

Updating and Upgrading CryptPad

⬆️ Updating Docker Images

Update CryptPad with Docker:


docker-compose pull

docker-compose down

docker-compose up -d

🛠️ Manual Updates

Pull the latest code and rebuild:


cd /path/to/cryptpad
