Resolving "mysql_connect(): No Connection Could Be Made Due to Refusal by Target Machine"
When attempting to execute a PHP MySQL script, some users encounter the error "mysql_connect(): No connection could be made because the target machine actively refused it." This error arises not due to code issues but rather due to external factors.
To resolve this error, follow these steps:
1. Verify Port Configuration:
Ensure that the connection port is set to the default port 3306.
2. Use IP Address Instead of Hostname:
Try replacing "localhost" with "127.0.0.1" as it may be listening on that address.
3. Check UDP vs. TCP Connection:
Confirm that the connection is not attempting to use UDP instead of TCP.
4. Investigate Firewall Settings:
Ensure that your firewall is configured to allow the database connection.
By addressing these external factors, you can resolve the error and establish a successful connection to the MySQL database.
