Gazelle

Gazelle is a web framework geared towards private BitTorrent trackers. Although naturally focusing on music, it can be modified for most needs. Gazelle is written in PHP, JavaScript, and MySQL.

Gazelle Runtime Dependencies

• Nginx (recommended)
• PHP 7 or newer (required)
• Memcached (required)
• Sphinx 2.0.6 or newer (required)
• procps-ng (recommended)

Gazelle/Ocelot Compile-time Dependencies

• Git (required)
• GCC/G++ (4.7+ required; 4.8.1+ recommended)
• Boost (1.55.0+ required)

Note: This list may not be exhaustive.

Logchecker

To fully utilize the Logchecker, you must install the following depedencies through pip:

• chardet
• eac-logchecker
• xld-logchecker

Gazelle Development

Gazelle can be run through Docker (container) or Vagrant (Virtual Machine). Historically, Vagrant was used, but recently Docker support was added and is the preferred method of development.

Docker (Recommended)

Install Docker for your preferred system and run the following command:

docker-compose up

This will build and pull the needed images to run Gazelle on Debian Buster. A volume is mounted from the base of the git repository at /var/www in the container. Changes to the source code are immediately served without rebuilding or restarting.

If you want to poke around inside the web container, open a shell:

export WEBCONT=$(docker ps|awk '$2 ~ /web$/ {print $1}')

docker exec -it $WEBCONT bash

To keep an eye on PHP errors during development:

docker exec -it $WEBCONT tail -n 20 -f /var/log/nginx/error.log

To create a Phinx migration:

docker exec -it $WEBCONT vendor/bin/phinx create MyNewMigration

Edit the resulting file and then apply it:

docker exec -it $WEBCONT vendor/bin/phinx migrate

You may want to install additional packages:

• apt update
• apt install less procps vim

To use Boris, you must enable certain pcntl_* functions that are disabled by default. Run the following inside the web container:

    grep '^disable_functions' /etc/php/7.3/cli/php.ini \
        | sed -r 's/pcntl_(signal|fork|waitpid|signal_dispatch),//g' \
        > /etc/php/7.3/cli/conf.d/99-boris.ini

You can then run Boris directly:

docker exec -it $WEBCONT /var/www/boris

To access the database, save the following in ~root/.my.cnf of the database container:

    [mysql]
    user = root
    password = <sekret>
    database = gazelle

And then: docker exec -it $(docker ps|awk '$2 ~ /^mariadb/ {print $1}') mysql

In the same vein, you can use mysqldump to perform a backup.

Production Mode (not fully baked yet)

In order to have Docker build the container using the production mode commands for both Composer and NPM, run this before powering it up:

docker-compose build --build-arg BuildMode=prod

Vagrant (Legacy)

This repository comes pre-setup to be run through Vagrant for ease of development and without having to modify your local machine. You can look through the docs for how it works, but to start, you just need to download Vagrant and VirtualBox (and it's recommended to get the vagrant-vbguest plugin) and then simply run: vagrant up

This will build a Debian Jessie on a Virtual Machine and serve this repository through /var/www on the machine.

Forwarded Ports

Both Docker and Vagrant will forward the following ports:

• 80 -> 8080 (web)
• 3306 -> 36000 (mysql)
• 34000 -> 34000 (ocelot)

You can access the site by going to http://localhost:8080
