= Starting a MySQL database

At this point, you have started ZooKeeper and Kafka,
but you still need a database server from which {prodname} can capture changes.
In this procedure, you will start a MySQL server with an example database.

.Procedure

. Open a new terminal, and use it to start a new container that runs a MySQL database server preconfigured with an `inventory` database.
+
--
This command runs a new container using version {debezium-docker-label} of the `quay.io/debezium/example-mysql` image, which is https://github.com/debezium/docker-images/blob/main/examples/mysql/{debezium-docker-label}/Dockerfile[based on] the https://hub.docker.com/r/_/mysql/[mysql:8.0] image.
It also defines and populates a sample `inventory` database:

[source,shell,options="nowrap",subs="attributes"]
----
$ docker run -it --rm --name mysql -p 3306:3306 -e MYSQL_ROOT_PASSWORD=debezium -e MYSQL_USER=mysqluser -e MYSQL_PASSWORD=mysqlpw quay.io/debezium/example-mysql:{debezium-docker-label}
----

`-it`:: The container is interactive,
which means the terminal's standard input and output are attached to the container.
`--rm`:: The container will be removed when it is stopped.
`--name mysql`:: The name of the container.
`-p 3306:3306`:: Maps port `3306` (the default MySQL port) in the container to the same port on the Docker host so that applications outside of the container can connect to the database server.
`-e MYSQL_ROOT_PASSWORD=debezium -e MYSQL_USER=mysqluser -e MYSQL_PASSWORD=mysqlpw`:: Creates a user and password that has the minimum privileges required by the {prodname} MySQL connector.

[NOTE]
====
If you use Podman, run the following command:
[source,shell,options="nowrap",subs="+attributes"]
----
$ sudo podman run -it --rm --name mysql --pod dbz -e MYSQL_ROOT_PASSWORD=debezium -e MYSQL_USER=mysqluser -e MYSQL_PASSWORD=mysqlpw quay.io/debezium/example-mysql:{debezium-docker-label}
----
====
endif::community[]

. Verify that the MySQL server starts.

--
The MySQL server starts and stops a few times as the configuration is modified.
You should see output similar to the following:

[source,shell,options="nowrap"]
----
...
[System] [MY-010931] [Server] /usr/sbin/mysqld: ready for connections. Version: '8.0.27'  socket: '/var/run/mysqld/mysqld.sock'  port: 3306  MySQL Community Server - GPL.
[System] [MY-011323] [Server] X Plugin ready for connections. Bind-address: '::' port: 33060, socket: /var/run/mysqld/mysqlx.sock
