What is this?
Installing MySQL means getting the mysqld server and mysql client on your machine. On Windows you use the MySQL Installer; on macOS/Linux you use packages or Homebrew. After install, the service listens on port 3306.
Why should you care?
Without a running server, every DataFlow lesson fails at connection time. Teams also Dockerize MySQL so everyone shares the same version.
See it live — copy this example
Run in MySQL Workbench or the mysql CLI.
# After install, from terminal:
mysql -u root -p -e "SELECT 'MySQL is up' AS status;"Run Example »
This lesson uses terminal or setup steps. Run commands on your computer — the live editor appears on coding lessons.
What happened?
- The mysql client connects with -u root -p (password prompt).
- -e runs one SQL string and exits.
- Seeing status proves install and service are working.
Practice next
- Download MySQL Community Server 8.x from mysql.com.
- Run the installer; note the root password you set.
- Open Command Prompt and run mysql -u root -p.
- Connect with mysql -h 127.0.0.1 -P 3306 -u root -p.
- Run SHOW VARIABLES LIKE 'port'; to confirm the port.
Remember
You need mysqld running locally or in cloud. mysql CLI proves the install quickly. Default port is 3306.
DataFlow local dev box
Each developer installs MySQL 8 and seeds DataFlow from a shared SQL dump before building features.
Outcome: Same schema everywhere — fewer “works on my machine” bugs.
