If you are not a developer, please visit the website for Racing+.

This is the server software for Racing+, a Binding of Isaac: Repentance racing platform. Normally a single player game, the Lua mod, client, and server allow players to be able to race each other in real time.

The server is written in Go and uses WebSockets to communicate with the client. It leverages the Steam API for authentication and uses a MariaDB database to keep track of the races.

You may also be interested in the Electron client or the Lua mod.

These instructions assume you are running Ubuntu 16.04 LTS. Some adjustment will be needed for Windows or MacOS installations.

• Install Go:
  • sudo add-apt-repository ppa:longsleep/golang-backports (if you don't do this, it will install a version of Go that is very old)
  • sudo apt update
  • sudo apt install golang-go -y
  • mkdir "$HOME/go"
  • export GOPATH=$HOME/go && echo 'export GOPATH=$HOME/go' >> ~/.profile
  • export PATH=$PATH:$GOPATH/bin && echo 'export PATH=$PATH:$GOPATH/bin' >> ~/.profile
• Install MariaDB:
  • sudo apt install mariadb-server -y
  • sudo mysql_secure_installation
    • Follow the prompts.
• Set up a MariaDB database and a MariaDB user:
  • sudo mysql -u root -p
    • CREATE DATABASE isaac;
    • CREATE USER 'isaacuser'@'localhost' IDENTIFIED BY '1234567890'; (change the password to something else)
    • GRANT ALL PRIVILEGES ON isaac.* to 'isaacuser'@'localhost';
    • FLUSH PRIVILEGES;
• Clone the repository:
  • cd [the path where you want the code to live] (optional)
  • If you already have an SSH key pair and have the public key attached to your GitHub profile, then use the following command to clone the repository via SSH:
    • git clone git@github.com:Zamiell/isaac-racing-server.git
  • If you do not already have an SSH key pair, then use the following command to clone the repository via HTTPS:
    • git clone https://github.com/Zamiell/isaac-racing-server.git
  • Or, if you are doing development work, then clone your forked version of the repository. For example:
    • git clone https://github.com/[Your_Username]/isaac-racing-server.git
• Enter the cloned repository:
  • cd isaac-racing-server
• Build the server, which will automatically download install all of the Go dependencies:
  • ./build.sh
• Set up environment variables:
  • cp .env.example .env
  • nano .env
    • Create a random 64 digit alphanumeric string for SESSION_SECRET.
    • Change the DB_PASS value accordingly.
    • If you want to be able to login to the WebSocket server, set a value for STEAM_WEB_API_KEY. (You can get it from the Steam community portal.)
    • The rest of the values can be left blank.
• Import the database schema:
  • mysql -uisaacuser -p < install/database_schema.sql

• To re-compile and run the server, simply run the run.sh script.
  • The re-compiled binary is called isaac-racing-server and is located in the root of the repository.
• If you are on Linux or MacOS, sudo might be necessary because the server listens on port 80 and/or 443.

• apt-install letsencrypt
• letsencrypt certonly --standalone -d isaacracing.net -d www.isaacracing.net (this creates /etc/letsencrypt/live/isaacracing.net)

Later, to renew the certificate:

• RENEW_DIR=/root/isaac-racing-server/letsencrypt && mkdir -p $RENEW_DIR && letsencrypt renew --webroot --webroot-path $RENEW_DIR && rm -rf $RENEW_DIR

• Install Supervisor:
  • apt install supervisor
  • systemctl enable supervisor (this is needed due to a quirk in Ubuntu 16.04)
• Copy the configuration files:
  • mkdir -p "/etc/supervisor" "/etc/supervisor/conf.d"
  • cp "/root/isaac-racing-server/install/supervisor/supervisord.conf" "/etc/supervisor/supervisord.conf"
  • cp "/root/isaac-racing-server/install/supervisor/isaac-racing-server.conf" "/etc/supervisor/conf.d/isaac-racing-server.conf"
• Start it: systemctl start supervisor

Later, to manage the service:

• Start it: supervisorctl start isaac-racing-server
• Stop it: supervisorctl stop isaac-racing-server
• Restart it: supervisorctl restart isaac-racing-server
