[php] mysqli_connect(): (HY000/2002): No connection could be made because the target machine actively refused it

For those who came here looking for the answer and didnt type 3306 wrong...If like myself, you have wasted hours with no luck searching for this answer, then possibly this may help.

If you are seeing this: (HY000/2002): No connection could be made because the target machine actively refused it

Then my understanding is that it cant connect for one of the following below. Now which..

1) is your wamp, mamp, etc icon GREEN? Either way, right-click the icon --> click tools --> test both the port used for Apache (typically 80) and for Mariadb (3307?). Should say 'It is correct' for both.

2) Error comes from a .php file. So, check your dbconnect.php.

<?php
$servername = "localhost";
$username = "your_username";
$password = "your_pw";
$dbname = "your_dbname";
$port = "3307";
?>

Is your setup correct? Does your user exist? Do they have rights? Does port match the tested port in 1)? Doesn't have to be 3307 and user can be root. You can also left click the green icon --> click MariaDB and view used port as shown in the image below. All good? Positive? ok!

3) Error comes when you login to phpmyadmin. So, check your my.ini.

enter image description here

Open my.ini by left clicking the green icon --> click MariaDB -->

; The following options will be passed to all MariaDB clients
[client]
;password = your_password
port = 3307
socket = /tmp/mariadb.sock

; Here follows entries for some specific programs

; The MariaDB server
[wampmariadb64]
;skip-grant-tables
port = 3307
socket = /tmp/mariadb.sock

Make sure the ports match the port MariaDB is being testing on. Then finally..

[mysqld]
port = 3307

At the bottom of my.ini, make sure this port matches as well.

4) 1-3 done? restart your WAMP and cross your fingers!
