Manual Installation

  1. Download the latest releases of Pressbooks, McLuhan, and Aldine, as well as the latest releases of any other book themes you wish to install. Check the latest release of Pressbooks for the required versions of PHP and WordPress. Lower versions are not supported.
  2. Follow the instructions provided by WordPress to install WordPress and create a WordPress multisite network
  3. Copy the Pressbooks plugin folder to: /path/to/your/site/wp-content/plugins/*.
  4. Copy Pressbooks' autoloader file from /path/to/your/site/wp-content/plugins/pressbooks/hm-autoloader.php to /path/to/your/site/wp-content/mu-plugins/hm-autoloader.php. You may need to create the wp-content/mu-plugins/ directory if it doesn't yet exist.
  5. Copy the Pressbooks Book, Pressbooks Aldine and other theme folders to: /path/to/your/site/wp-content/themes/* (NOTE: theme folders must not have version numbers on the end. GOOD: pressbooks-aldine. BAD: pressbooks-aldine-3.1.0. Make sure that you rename the folders appropriately.)

Server Dependencies

Pressbooks requires some third-party libraries to be installed on your server to enable export capabilities.

Note: Certain GNU/Linux distributions do not ship with the php-xsl and/or php-exif libraries enabled by default. If you attempt to export an EPUB file and get either a white screen with minimal text, or an error, you may need install one or both of these libraries: (e.g. sudo apt install php-xsl or sudo apt install php-exif )

Note: GNU/Linux distributions do not include Microsoft fonts, which can be useful when producing PDF exports. See or similar for instructions on installing.

Once the desired dependencies have been installed on your server, define the following wp-config.php variables (make sure to update the paths to correspond to your specific installation). The defaults are:

define( 'PB_PRINCE_COMMAND', '/usr/bin/prince' ); // Only required if you are using Prince on your server define( 'PB_EPUBCHECK_COMMAND', '/usr/bin/java -jar /opt/epubcheck/epubcheck.jar' ); define( 'PB_XMLLINT_COMMAND', '/usr/bin/xmllint' ); define( 'PB_SAXON_COMMAND', '/usr/bin/java -jar /opt/saxon-he/saxon-he.jar' ); define( 'PB_MATHJAX_URL', 'http://localhost:3000/' );

Configure Network Settings & Create Your First Book

  1. Navigate to Network AdminDashboard → Settings** → **Network Settings** and select the most appropriate Registration setting:
    • User accounts may be registered. (User accounts can be registered, but these users will not be able to create their own books)
    • Logged in users may register new sites. (Network administrators can add new users, who can then create their own books (i.e. sites)
    • Both sites and user accounts can be registered. (Allows visitors to your network to create their own accounts and then create their own books without central moderation. If you choose this option, you will likely need to have good account and content moderation practices to avoid your network being flooded with spam.)
