How to Install DOMJudge on Alpine Linux Latest

DOMJudge is an open source system for running programming contests, developed by a Dutch university. In this tutorial, we will guide you through the process of installing DOMJudge on Alpine Linux Latest.

Prerequisites

Before proceeding with the installation, ensure that your system meets the following requirements:

  • Alpine Linux Latest installed
  • Administrative access to the system
  • Basic familiarity with the Alpine Linux command line interface

Step 1: Install Required Packages

DOMJudge requires several packages to run properly. These packages can be installed by running the following command:

sudo apk add php7 php7-iconv php7-json php7-mbstring php7-xml php7-zip php7-pdo php7-pdo_mysql mariadb mariadb-client apache2 apache2-utils

This command will install PHP, MariaDB, Apache, and other necessary packages.

Step 2: Configure MariaDB

DOMJudge requires a MariaDB database to function. You can configure MariaDB by running the following commands:

sudo /etc/init.d/mariadb setup
sudo /etc/init.d/mariadb start
mysql_secure_installation

The last command will guide you through securing your MariaDB installation by setting a root password and removing anonymous users, among other things.

Step 3: Install DOMJudge

Once the prerequisites are installed and MariaDB is configured, you can proceed with installing DOMJudge. To install DOMJudge, follow these steps:

  1. Download the latest version of DOMJudge from the official website by running the following command:
wget https://www.domjudge.org/releases/domjudge-7.3.3.tar.gz
  1. Extract the downloaded archive by running the following command:
tar -xzf domjudge-7.3.3.tar.gz
  1. Move the extracted files to the Apache root directory by running the following command:
sudo mv domjudge-7.3.3 /var/www/html/domjudge/
  1. Change the ownership of the files to the Apache user by running the following command:
sudo chown -R apache:apache /var/www/html/domjudge/
  1. Launch the web-based installer by accessing the URL http://<your_server_address>/domjudge/install.php in a web browser, where your_server_address is the IP address or hostname of your server. Follow the prompts in the web installer to complete the installation.

Conclusion

DOMJudge is now installed and ready to use. You can access the DOMJudge administration interface by navigating to http://<your_server_address>/domjudge. Remember to secure your installation by configuring HTTPS and securing your MariaDB installation further.
