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
📦 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.
🚀 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
🔒 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.
🛠️ 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
🗃️ 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.
📄 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).
🛠️ 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
📤 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
🗂️ File-Based Backups
Create a snapshot of your configuration and library:
tar -czvf calibre-backup.tar.gz /path/to/config /path/to/library
🔄 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
📅 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
🛠️ 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
🔍 Checking for Updates
Monitor the Calibre-Web GitHub repository for release notes and update notifications.
Leveraging Calibre-Web’s Unique Features
🔧 Enabling APIs
Activate Calibre-Web’s APIs by enabling the feature in the admin settings. Use the API with tools like curl:
