Table of Contents

Calibre-Web is a lightweight, self-hosted web application designed to manage and access eBook libraries. It serves as a polished, user-friendly frontend for the popular Calibre eBook manager, making it an excellent choice for those who want to access their eBooks from anywhere while retaining complete control over their data. In this guide, we’ll cover how to deploy, configure, and manage Calibre-Web, leveraging its unique features to create a powerful eBook management system tailored to your needs.

Installing Calibre-Web

πŸ“¦ Docker/Docker Compose Setup

Using Docker is one of the most efficient ways to deploy Calibre-Web. Below is a docker-compose.yml tailored for Calibre-Web:


version: '3.7'

services:

calibre-web:

image: linuxserver/calibre-web:latest

container_name: calibre-web

ports:

- "8083:8083" # Map Calibre-Web's default port

volumes:

- /path/to/config:/config # Persistent storage for Calibre-Web's configuration

- /path/to/library:/books # Path to your eBook library

environment:

- PUID=1000 # Set your user ID

- PGID=1000 # Set your group ID

- TZ=Etc/UTC # Replace with your timezone

restart: unless-stopped

To deploy the container, save the file as docker-compose.yml and run the following:


docker-compose up -d

This command will pull the latest Calibre-Web image, create the container, and start the service.

πŸš€ Manual Installation

If Docker isn’t an option, you can install Calibre-Web manually on a Linux server. Run the following commands to set it up:


sudo apt update && sudo apt install -y python3 python3-pip git

## Clone the Calibre-Web repository

git clone https://github.com/janeczku/calibre-web.git /opt/calibre-web

## Navigate to the installation directory

cd /opt/calibre-web

## Install Python dependencies

pip3 install --user -r requirements.txt

## Start the application

python3 cps.py

Calibre-Web will start on port 8083 by default. You can access it by visiting http://<server-ip>:8083.

Configuring Nginx as a Reverse Proxy

🌐 Nginx Configuration

Setting up Nginx as a reverse proxy allows you to serve Calibre-Web over a custom domain. Create a new Nginx configuration file for the site:


server {

listen 80;

server_name yourdomain.com;

location / {

proxy_pass http://127.0.0.1:8083;

proxy_set_header Host $host;

proxy_set_header X-Real-IP $remote_addr;

proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

}

}

Save the file in /etc/nginx/sites-available/calibre-web and create a symbolic link to enable it:


sudo ln -s /etc/nginx/sites-available/calibre-web /etc/nginx/sites-enabled/

sudo nginx -t

sudo systemctl reload nginx

πŸ”’ SSL/TLS Setup

Secure your setup with Let’s Encrypt using Certbot:


sudo apt install -y certbot python3-certbot-nginx

sudo certbot --nginx -d yourdomain.com

This command automatically configures SSL and sets up certificate renewals.

πŸ› οΈ Testing and Reloading Nginx

After configuring, test the Nginx setup:


sudo nginx -t

sudo systemctl reload nginx

Access your secure Calibre-Web instance at https://yourdomain.com.

Logging and Debugging Calibre-Web

πŸ—ƒοΈ Enabling Debug Logs

Enable debug-level logging to diagnose issues. Edit the Calibre-Web configuration file (usually config.py):


LOG_LEVEL = "DEBUG"

Restart Calibre-Web to apply the changes.

πŸ“„ Viewing Logs

For Docker setups, view logs using:


docker logs calibre-web

For manual installations, check the log file (e.g., /opt/calibre-web/calibre-web.log).

πŸ› οΈ Troubleshooting Common Issues

Look for error messages in the logs, such as missing dependencies or incorrect file permissions. For example, fix permission issues with:


sudo chown -R $USER:$USER /path/to/library

πŸ“€ Exporting Logs

Send logs to an external system (e.g., ELK Stack) by piping Docker logs:


docker logs calibre-web | curl -X POST -H "Content-Type: application/json" -d @- http://elk-stack-endpoint:9200/logs

Backup and Restore

πŸ—‚οΈ File-Based Backups

Create a snapshot of your configuration and library:


tar -czvf calibre-backup.tar.gz /path/to/config /path/to/library

πŸ”„ Database Backups

Export the internal SQLite database:


sqlite3 /path/to/config/app.db ".backup calibre-db-backup.sqlite"

Restore with:


sqlite3 /path/to/config/app.db < calibre-db-backup.sqlite

πŸ“… Automated Backup Scripts

Schedule periodic backups using cron:


crontab -e

## Add the following line:

0 2 * * * tar -czvf /backups/calibre-backup-$(date +\%F).tar.gz /path/to/config /path/to/library

Updating and Upgrading Calibre-Web

⬆️ Updating Docker Images

Pull the latest Docker image and redeploy:


docker-compose pull

docker-compose down

docker-compose up -d

πŸ› οΈ Manual Updates

If installed manually, update by pulling the latest code and reinstalling dependencies:


cd /opt/calibre-web

git pull

pip3 install --user -r requirements.txt

python3 cps.py

πŸ” Checking for Updates

Monitor the Calibre-Web GitHub repository for release notes and update notifications.

Leveraging Calibre-Web’s Unique Features

πŸ”§ Enabling APIs

Activate Calibre-Web’s APIs by enabling the feature in the admin settings. Use the API with tools like curl:


curl -X GET -H "Authorization: Bearer your-api-token" http://yourdomain.com/api/v1/books

🌟 Advanced Configurations

Enable custom themes, integrate third-party tools, or adjust settings in the admin panel. For instance, configure OAuth for user authentication via the admin interface or JSON configuration files.
