How can I use MySQL command with a custom port number?

To resolve the issue:

1. Confirm MySQL is configured for port 3307.
2. Check MySQL server status: mysqladmin -u root -p -h 127.0.0.1 -P 3307 status.
3. Update mysqldump command: mysqldump -u root -p -P 3307 database > "path_to_dumpfile\database.sql".
4. Ensure firewall allows connections on port 3307.
5. Verify MySQL user privileges for root on 127.0.0.1. If issues persist, check error messages for details.
