Nov 02, 2024 pm 04:14 PMTroubleshooting "mysql_connect(): No Connection Could Be Made" Error
When attempting to establish a database connection using mysql_connect(), users may encounter the error "No connection could be made because the target machine actively refused it." This typically indicates that the issue lies outside of the PHP code itself and relates to network connectivity or firewall settings.
To address this error, it's crucial to verify various aspects:
- Port Configuration: Ensure that the MySQL server is listening on port 3306. Reconfigure it if necessary to match your script's port settings.
- Host Address: Try using "127.0.0.1" or the specific IP address of the server instead of "localhost." Sometimes, servers listen on specific IP addresses, not the hostname.
- Protocol Compatibility: Confirm that your connection is using the correct protocol (TCP or UDP). The default is typically TCP, but it's worth checking to be sure.
- Firewall Restrictions: Check your local firewall settings and ensure that they allow connections to the MySQL server on the specified port. Adjust the rules to permit access if necessary.
By addressing these potential issues, you can overcome the "No connection could be made" error and successfully establish a connection to your MySQL database.
