Understanding Node.js ECONNREFUSED Error with MySQL
When attempting to establish a connection to a MySQL database using Node.js, developers may encounter the error message "connect ECONNREFUSED." This indicates a connection refusal on the server side, effectively preventing the client application from accessing the database.
The code snippet provided in the query includes the following configuration:
<code class="javascript">var client = mysql.createClient({ user: 'root', password: 'root', });</code>
However, it lacks explicit specification of the database host and port. Without these details, the default host (localhost) and port (3306) are assumed.
To resolve the ECONNREFUSED error, consider the following solutions:
Solution 1: Disable Skip Networking
Solution 2: Specify Socket Path
If connecting using the MySQL socket, configure the client like this:
<code class="javascript">var client = mysql.createClient({ user: uuuu, password: pppp, host: '127.0.0.1', port: '3306', _socket: '/var/run/mysqld/mysqld.sock', });</code>
