Mellivora is a CTF engine written in PHP. Want a quick overview? Check out a screenshot gallery on imgur.

• LAMP: PHP 5.5.9+, MySQL 5.5+, Apache 2.2+. Will likely work with other configurations but this is untested.
• Composer dependency manager for PHP.

Mellivora scales well on Amazon Elastic Beanstalk and has support for S3 file storage.

Mellivora is lightweight. And fast. Very fast. Want to run a large competition on an EC2 micro instance? No problem!? See benchmarks.md for some possibly unhelpful benchmarks.

You can find detailed setup instructions in install/README.md. In short:

• Download to any directory, say: "/var/www/mellivora/".
• Run "composer install" in the root directory to install all required dependencies.
• Create an Apache VHost and point DocumentRoot to "htdocs/". An example Apache config can be found in the "install/" directory.
• Create a database and import the structure from "install/mellivora.sql". Import country list from "install/countries.sql".
• In the "config/" directory: copy .example files to "config.inc.php" and "db.inc.php". Edit both to suit your setup.
• Make the "writable/" directory and its subdirectories writable by Apache.
• Create a user by signing up to the site. Make the user an administrator by manually changing its "class" value to "CONST_USER_CLASS_MODERATOR" (default: 100) in the "users" table in the database.
