Quick start

  1. Install dependencies by running pip install --target vendor -r requirements.txt.
  2. Execute the command: python cps.py (or nohup python cps.py - recommended if you want to exit the terminal window)
  3. Point your browser to http://localhost:8083 or http://localhost:8083/opds for the OPDS catalog
  4. Set Location of Calibre database to the path of the folder where your Calibre library (metadata.db) lives, push "submit" button optionally a google drive can be used to host the calibre library (-> Using Google Drive integration)
  5. Go to Login page

Default admin login: Username: admin Password: admin123

Runtime Configuration Options

The configuration can be changed as admin in the admin panel under "Configuration"

Server Port: Changes the port Calibre-Web is listening, changes take effect after pressing submit button

Enable public registration:
Tick to enable public user registration.

Enable anonymous browsing:
Tick to allow not logged in users to browse the catalog, anonymous user permissions can be set as admin ("Guest" user)

Enable uploading: Tick to enable uploading of PDF, epub, FB2. This requires the imagemagick library to be installed.

Enable remote login ("magic link"): Tick to enable remote login, i.e. a link that allows user to log in via a different device.

Requirements

Python 2.7+

Optionally, to enable on-the-fly conversion from EPUB to MOBI when using the send-to-kindle feature:

Download Amazon's KindleGen tool for your platform and place the binary named as kindlegen in the vendor folder.

Using Google Drive integration

Calibre Calibre library (metadata.db) can be located on a Google Drive. Additional optional dependencys are necessary to get this work. Please install all optional requirements by executing pip install --target vendor -r optional-requirements.txt

To use google drive integration, you have to use the google developer console to create a new app. https://console.developers.google.com

Once a project has been created, we need to create a client ID and a client secret that will be used to enable the OAuth request with google, and enable the Drive API. To do this, follow the steps below: -

  1. Open project in developer console
  2. Click Enable API, and enable google drive
  3. Now on the sidebar, click Credentials
  4. Click Create Credentials and OAuth Client ID
  5. Select Web Application and then next
  6. Give the Credentials a name and enter your callback, which will be CALIBRE_WEB_URL/gdrive/callback
  7. Click save
  8. Download json file and place it in calibre-web directory, with the name client_secrets.json

The Drive API should now be setup and ready to use, so we need to integrate it into Calibre-Web. This is done as below: -

  1. Open config page
  2. Enter the location that will be used to store the metadata.db file locally, and to temporary store uploaded books and other temporary files for upload ("Location of Calibre database")
  3. Tick Use Google Drive
  4. Click the "Submit" button
  5. Now select Authenticate Google Drive
  6. This should redirect you to Google. After allowing it to use your Drive, it redirects you back to the config page
  7. Select the folder that is the root of your calibre library on Gdrive ("Google drive Calibre folder")
  8. Click the "Submit" button
  9. Google Drive should now be connected and be used to get images and download Epubs. The metadata.db is stored in the calibre library location

Optional

If your calibre web is using https, it is possible to add a "watch" to the drive. This will inform us if the metadata.db file is updated and allow us to update our calibre library accordingly. Additionally the public adress your server uses (e.g.https://example.com) has to be verified in the Google developer console. After this is done, please wait a few minutes.

  1. Open config page
  2. Click enable watch of metadata.db
  3. Note that this expires after a week, so will need to be manually refresh

Reverse Proxy

Reverse proxy configuration examples for apache and nginx to use Calibre-Web:

nginx configuration for a local server listening on port 8080, mapping calibre web to /calibre:

http {
    upstream calibre {
        server  127.0.0.1:8083;
    }
    server {
            client_max_body_size 20M;
            location /calibre {
                proxy_bind              $server_adress;
                proxy_pass              http://127.0.0.1:8083;
                proxy_set_header        Host            $http_host;
                proxy_set_header        X-Forwarded-For $proxy_add_x_forwarded_for;
                proxy_set_header        X-Scheme        $scheme;
                proxy_set_header        X-Script-Name   /calibre;
        }
    }
}

Note: If using SSL in your reverse proxy on a non-standard port (e.g.12345), the following proxy_redirect line may be required:

proxy_redirect http://$host/ https://$host:12345/;

Apache 2.4 configuration for a local server listening on port 443, mapping calibre web to /calibre-web:

The following modules have to be activated: headers, proxy, rewrite.

Listen 443

<VirtualHost *:443>
    SSLEngine on
    SSLProxyEngine on
    SSLCipherSuite ALL:!ADH:!EXPORT56:RC4+RSA:+HIGH:+MEDIUM:+LOW:+SSLv2:+EXP:+eNULL
    SSLCertificateFile "C:\Apache24\conf\ssl\test.crt"
    SSLCertificateKeyFile "C:\Apache24\conf\ssl\test.key"
    
    <Location "/calibre-web" >
        RequestHeader set X-SCRIPT-NAME /calibre-web
        RequestHeader set X-SCHEME https
        ProxyPass http://localhost:8083/
        ProxyPassReverse http://localhost:8083/
    </Location>
</VirtualHost>

(Optional) SSL Configuration

For configuration of calibre-web as SSL Server go to the Config page in the Admin section. Enter the certfile- and keyfile-location, optionally change port to 443 and press submit. Afterwards the server can only be accessed via SSL. In case of a misconfiguration (wrong/invalid files) both files can be overridden via command line options -c [certfile location] -k [keyfile location] By using "" as file locations the server runs as non SSL server again. The correct file path can than be entered on the Config page. After the next restart without command line options the changed file paths are applied.

Start Calibre-Web as service under Linux

Create a file "cps.service" as root in the folder /etc/systemd/system with the following content:

Description=Calibre-Web

[Service]
Type=simple
User=[Username]
ExecStart=[path to python] [/PATH/TO/cps.py]
WorkingDirectory=[/PATH/TO/cps.py]

[Install]
WantedBy=multi-user.target

Replace the user and ExecStart with your user and foldernames.

sudo systemctl enable cps.service

enables the service.

Command line options

Starting the script with -h lists all supported command line options Currently supported are 2 options, which are both useful for running multiple instances of Calibre-Web

"-p path" allows to specify the location of the settings database "-g path" allows to specify the location of the google-drive database "-c path" allows to specify the location of SSL certfile, works only in combination with keyfile "-k path" allows to specify the location of SSL keyfile, works only in combination with certfile
