Which port does MySQL listen on by default?

Explanation:
MySQL listens on 3306 by default. This standard port is what the server binds to when you install MySQL and keep the default configuration, so clients connect to the server using host:3306 unless you explicitly change it. You can verify or change this in the server’s config (port = 3306 in my.cnf or my.ini) and confirm from the server with commands like SHOW VARIABLES LIKE 'port', or by observing the listening socket with netstat/ss. The other port numbers correspond to different services—1433 is used by Microsoft SQL Server, 21 is FTP, and 3389 is Remote Desktop—so they aren’t the default for MySQL.
