PHP MySQL Connection Refused (Error 2002): How Can I Fix It?

PHP Connection Failed: Understanding [2002] Connection Refused Error

When attempting to establish a PHP connection to a MySQL database on phpMyAdmin, you encountered the "Connection failed: SQLSTATE[HY000] [2002] Connection refused" error. To resolve this issue, consider the following steps:

Original Server Name Configuration:

Your initial connection attempt used 'localhost' as the server name, which may have caused the "No such file or directory" error. Changing this to the IP address of your database host should fix the issue.

Correct Port Configuration:

By default, MAMP's database service runs on port 8889, not 8888. Adjust the connection string to connect to the correct port:

$conn = new PDO("mysql:host=$servername;port=8889;dbname=AppDatabase", $username, $password); 

Consideration:

While using the server IP address in the connection string resolves the connection issue, using 'localhost' as the server name still triggers the "No such file or directory" error. This could indicate a configuration issue in the mysql.cnf file or the firewall settings on your computer.

Additional Troubleshooting:

If the above steps do not resolve the issue, consider the following:

• Ensure that your firewall allows connections to the database port (8889).
• Check the permissions and privileges of the user account you are using to connect to the database.
• Verify that the database name specified in the connection string is correct.
• Review the mysql.cnf configuration file for any potential issues or inconsistencies.
