How to Address "No Connection Could Be Made Because the Target Machine Actively Refused It" Error in MySQL

When attempting to connect to a MySQL database, users may encounter an error message indicating that no connection could be made due to an active refusal by the target machine. This error can arise for various reasons, but one common root cause is incorrect MySQL configuration.

Problem Statement

A developer attempting to establish a connection to a remote database using PHP encounters an error: "No connection could be made because the target machine actively refused it." The code used for the connection includes mysqli_connect function with specified database parameters.

Solution

The error suggests that the MySQL server is configured to only accept connections from specific IP addresses or is not allowing connections from the network. To resolve this issue, adjustments to the MySQL configuration file are necessary:

  1. Locate the my.cnf configuration file (usually found in /etc/mysql/my.cnf on Ubuntu).
  2. Make the following changes within the file:

    • Set bind-address to 0.0.0.0 to allow connections from any IP address.
    • Comment out #skip-networking to enable network connections.
  3. Restart the MySQL server to apply the changes.

Caution

Allowing connections from all IP addresses may increase security risks. Therefore, granting access to only trusted networks is recommended.
