# mysqladm-rs

Work in progress rewrite of https://git.pvv.ntnu.no/Projects/mysql-admutils

## Installation

The resulting binary will probably need to be marked as either SUID or SGID to work in a multi-user environment.
The UID/GID of the binary should have access to the config file, which contains secrets to log in to an admin-like MySQL user.
Preferrably, this UID/GID should not be root, in order to minimize the potential damage that can be done in case of security vulnerabilities in the program.

## Development and testing

Ensure you have a [rust toolchain](https://www.rust-lang.org/tools/install) installed.

In order to set up a test instance of mariadb in a docker container, run the following command:

```bash
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:

```bash
cp ./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.

```bash
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-db-perm -p "${USER}_testdb:${USER}_testuser:A"
cargo run -- --config-file ./config.toml show-db-perm
```

To stop and remove the container, run the following command:

```bash
docker stop mariadb
```
