Starting DOMjudge

A simple guide for starting DOMjudge using some helper Bash scripts

Initialization

1. Clone this repository.
2. Run chmod +x *.sh command.

Start server

1. Run ./config_user_and_grub.sh command.
2. Restart your computer.
3. You can modify DOMJUDGE_VERSION and MARIADB_VERSION variables in config_docker.sh file (according to the latest released versions). Also, you can leave them unchanged.
4. Run ./config_docker.sh command.
5. You can modify DOMJUDGE_VERSION, MYSQL_PASSWORD, and MYSQL_ROOT_PASSWORD variables in start_server.sh file. Also, you can leave them unchanged.
6. Run ./start_server.sh command.
7. Check http://localhost:12345 via your Web browser. You should see DOMjudge now!

Start workers

Suppose there is a working server on a machine. It doesn't matter the worker and the server are on the same machine or not; you should start a server beside the worker.

1. Run ./config_user_and_grub.sh command.
2. Restart your computer.
3. You can modify DOMJUDGE_VERSION and MARIADB_VERSION variables in config_docker.sh file (according to the latest released versions). Also, you can leave them unchanged.
4. Run ./config_docker.sh command.
5. You can modify DOMJUDGE_VERSION, MYSQL_PASSWORD, and MYSQL_ROOT_PASSWORD variables in start_server.sh file. Also, you can leave them unchanged.
6. Run ./start_server.sh command.
7. Modify DOMJUDGE_VERSION, SERVER_URL, and WORKER_PASSWORD variables in start_server.sh file. The first one should be set to the URL of DOMjudge server, but the second one can have an arbitrary value.
8. Run ./start_worker.sh 0 command.
9. Now, a single worker (with ID 0) is up. You can start more concurrent workers on the same machine. For the next workers, just run ./start_worker.sh 1, ./start_worker.sh 2 and so on. The maximum number of workers equals the number of your machine CPU cores.

Notes

If you get an error like "You have to remove (or rename) that container to be able to reuse that name.", remove those conflicting containers using docker stop and docker rm commands with the given IDs. sudo may be needed as well.
