Quick Start

1. Access Calibre-Web: Open your browser and navigate to:

   http://localhost:8083
   

   or for the OPDS catalog:

   http://localhost:8083/opds
   

2. Log in: Use the default admin credentials:
   • Username: admin
   • Password: admin123
3. Database Setup: If you do not have a Calibre database, download a sample from:

   https://github.com/janeczku/calibre-web/raw/master/library/metadata.db
   

   Move it out of the Calibre-Web folder to avoid overwriting during updates.
4. Configure Calibre Database: In the admin interface, set the Location of Calibre database to the path of the folder containing your Calibre library (where metadata.db is located) and click "Save".
5. Google Drive Integration: For hosting your Calibre library on Google Drive, refer to the Google Drive integration guide.
6. Admin Configuration: Configure your instance via the admin page, referring to the Basic Configuration and UI Configuration guides.

Requirements

• Python Version: Ensure you have Python 3.7 or newer.
• Imagemagick: Required for cover extraction from EPUBs. Windows users may also need to install Ghostscript for PDF cover extraction.
• Windows Users: Install libmagic for 32bit python or libmagic for 64bit python, depending on your Python version. Make sure these files are included in your path.
• Optional Tools:
  • Calibre desktop program: Recommended for on-the-fly conversion and metadata editing. Set the path to Calibre’s converter tool on the setup page.
  • Kepubify tool: Needed for Kobo device support. Download the tool and place the binary in /opt/kepubify on Linux or C:\Program Files\kepubify on Windows.

Docker Images

Pre-built Docker images are available:

LinuxServer - x64, aarch64

• Docker Hub: linuxserver/calibre-web
• GitHub: linuxserver/docker-calibre-web
• Optional Calibre layer: linuxserver/docker-mods

Troubleshooting

• Common Issues:

  • If you experience issues starting the application, check the log files located in the logs directory for error messages.
  • If eBooks fail to load, verify that the Location of Calibre database is correctly set and that the database file is accessible.

• Configuration Errors: Ensure that your Calibre database is compatible and properly formatted. Refer to the Calibre documentation for guidance on maintaining the database.

• Performance Problems:

  • If the application is slow, consider increasing the allocated resources (CPU/RAM) to your server or optimizing the Calibre database by removing duplicates and unnecessary entries.
  • Regularly clear the cache in your web browser to improve loading times.

• User Management Issues: If users are unable to log in or register, check the user permission settings in the admin interface. Ensure that registration is enabled and that users are being assigned appropriate roles.

• Support Resources: For additional help, consider visiting the FAQ section of the wiki or posting your questions in the Discord community.
