Development and testing
Ensure you have a rust toolchain installed.
In order to set up a test instance of mariadb in a docker container, run the following command:
docker run --rm --name mariadb -e MYSQL_ROOT_PASSWORD=secret -p 3306:3306 -d mariadb:latest
This will start a mariadb instance with the root password secret, and expose the port 3306 on the host machine.
Run the following command to create a configuration file with the default settings:
cp ./assets/example-config.toml ./config.toml
If you used the docker command above, you can use these settings as is, but if you are running mariadb/mysql on another host, port or with another password, adjust the corresponding fields in config.toml.
This file will contain your database password, but is ignored by git, so it will not be committed to the repository.
You should now be able to connect to the mariadb instance, after building the program and using arguments to specify the config file.
cargo run -- --config-file ./config.toml <args>
# example usage
cargo run -- --config-file ./config.toml create-db "${USER}_testdb"
cargo run -- --config-file ./config.toml create-user "${USER}_testuser"
cargo run -- --config-file ./config.toml edit-privs -p "${USER}_testdb:${USER}_testuser:A"
cargo run -- --config-file ./config.toml show-privs
To stop and remove the container, run the following command:
docker stop mariadb
Development using Nix
If you have nix installed, you can easily test your changes in a NixOS vm by running:
nix run .#vm
You can configure the vm in flake.nix
Filter logs by user with journalctl
If you want to filter the server logs by user, you can use journalctl's built-in filtering capabilities.
journalctl -eu muscl F_USER=<username>
