Setup MySQL / MariaDB¶
If you already have your own MySQL database set up, you can skip this step and proceed with the next step to load TPC-H data.
In this tutorial, we will set up the MySQL database using Docker.
In this tutorial, we will launch MariaDB (i.e., open-source fork of MySQL), which is essentially equivalent to MySQL (at least for our tutorial), using Docker.
Docker is an open-source project for developers to create, deploy and run any application using containers.
You can download Docker here, and simply follow their instructions to install it.
Start Your Database¶
After you install Docker, you can launch a MySQL/MariaDB instance in a Docker container by running the following command:
docker run --rm -d --name verdictdb-mysql -p 127.0.0.1:3306:3306 \ -e MYSQL_DATABASE=test -e MYSQL_ALLOW_EMPTY_PASSWORD=yes mariadb:10
This command launches a MySQL/MariaDB instance locally using the default port of 3306. You can access this database as a user 'root' without passwords.
Port is already allocated?
You may receive the error like blow when starting the docker container.
userland proxy: Bind for 0.0.0.0:3306 failed: port is already allocated
This error simply means that there is already a process listening on the port 3306, e.g., already existing MySQL instance on your machine. You can either stop/terminate the MySQL instance and run the above docker command again. Or, you can simply use another port, e.g., 3305, to avoid the port conflict as follows:
docker run --rm -d --name verdictdb-mysql -p 127.0.0.1:3305:3306 \ -e MYSQL_DATABASE=test -e MYSQL_ALLOW_EMPTY_PASSWORD=yes mariadb:10
