If MySQL installation indicates that port 3306 is already in use, the solution is as follows:

  1. To check the process using port 3306: Open a command prompt window, type the following command, and press Enter:
  2. Show me information about port 3306 using the netstat command.
  3. Based on the output from the previous step, locate the PID (Process ID) of the process occupying port 3306.
  4. Open Task Manager: Press the Ctrl+Shift+Esc key combination to open Task Manager.
  5. Switch to the “Details” tab, locate the process corresponding to the PID, right-click on the process, and select “End Task.”
  6. Reinstall MySQL.

Note: If you cannot find a process occupying port 3306, it may be because the process is hidden or it is a less common process. You can try using a different port or closing related programs to release the port, then reinstall MySQL.
