Cannot Connect mysql from php with specific port - php

I have mysql 8.0.15 for windows and I'm trying to connect from remote php webSite but always getting
2002: Connection refused
The code I use to test the connection is very simple
$dbHost = "HOST";
$dbUser = "root";
$dbPass = "password";
$dbDB = "DBNAME";
$dbPort = "9999";
echo "Conectando a $dbHost,$dbUser,$dbPass,$dbDB,$dbPort ";
$link = mysqli_connect($dbHost,$dbUser,$dbPass,$dbDB,$dbPort);
if (!$link) {
echo "Error: Unable to connect to MySQL." . PHP_EOL;
echo "Debugging errno: " . mysqli_connect_errno() . PHP_EOL;
echo "Debugging error: " . mysqli_connect_error() . PHP_EOL;
exit;
}
echo "Success: A proper connection to MySQL was made! The my_db database is great." . PHP_EOL;
echo "Host information: " . mysqli_get_host_info($link) . PHP_EOL;
mysqli_close($link);
I also try host:port and p:host:port and always getting the same error message.

If you want to change the MySQL port, you have to edit the my.ini config-file on the MySQL server by setting port=<YOUR PREFERRED PORT>, then check if the port is forwarded and finally restart the MySQL server.

Encountering error 1045 while connecting php file to mysql database

I have been trying to connect my PHP file to MySQL database for a while, now I'm using WAMP server and encountering error 1045, I have also setup a password and tried various settings given on net.
this is the scenario
<?php
$link = mysqli_connect("127.0.0.1", "root", "password", "registration");
if (!$link) {
echo "Error: Unable to connect to MySQL." . PHP_EOL;
echo "Debugging errno: " . mysqli_connect_errno() . PHP_EOL;
echo "Debugging error: " . mysqli_connect_error() . PHP_EOL;
exit;
}
echo "Success: A proper connection to MySQL was made! The my_db database is great." . PHP_EOL;
echo "Host information: " . mysqli_get_host_info($link) . PHP_EOL;
mysqli_close($link);
?>
here is the code I'm running, registration is the database,I have created it using phpmyadmin
<?php
$link = mysqli_connect("127.0.0.1", "root", "", "registration");
if (!$link) {
echo "Error: Unable to connect to MySQL." . PHP_EOL;
echo "Debugging errno: " . mysqli_connect_errno() . PHP_EOL;
echo "Debugging error: " . mysqli_connect_error() . PHP_EOL;
exit;
}
echo "Success: A proper connection to MySQL was made! The my_db database is great." . PHP_EOL;
echo "Host information: " . mysqli_get_host_info($link) . PHP_EOL;
mysqli_close($link);
?>

I tried connecting my PHP file to MySQli database but when i ran the code it displays
But when i logon to phpmyadmin it works fine no errors i can login to my account with no problems
Credentials in the database:
Connection Code:
<?php
$con = mysqli_connect('localhost','sotomango', '1234', 'mysql');
if(!$con) {
echo 'noooo';
}
?>
I double checked the database usernames, passwords, and privileges. Everything seems in place and correct, but the php file wont allow me to connect to the database.
#Dharman had a nice post but I couldnt find it.
Try this for debug :
$con = mysqli_connect("127.0.0.1", "my_user", "my_password", "my_db");
if (!$con) {
echo "Error: Unable to connect to MySQL." . PHP_EOL;
echo "Debugging errno: " . mysqli_connect_errno() . PHP_EOL;
echo "Debugging error: " . mysqli_connect_error() . PHP_EOL;
exit;
}
echo "Success: A proper connection to MySQL was made! The my_db database is
great." . PHP_EOL;
echo "Host information: " . mysqli_get_host_info($con) . PHP_EOL;
mysqli_close($con);
mysqli_connect
if its a new instalation or new upgrade, You need to include your port into connection, mariadb comes as default port so, when you try to connect mysql its redirecting to mariadb.
you need to include your correct port into connection it might be 3306, 3307 or 3308, and use ip instead of localhost.
your final codes should look like this :
$host = '127.0.0.1';
$db = 'test';
$user = 'root';
$pass = '';
$port = '3308';
$charset = 'utf8mb4';
mysqli_report(MYSQLI_REPORT_ERROR | MYSQLI_REPORT_STRICT);
try {
$mysqli = mysqli_connect($host, $user, $pass, $port, $db);
mysqli_set_charset($mysqli, $charset);
} catch (\mysqli_sql_exception $e) {
throw new \mysqli_sql_exception($e->getMessage(), $e->getCode());
}
For The People Wondering
I solved this by just adding a port to the host name like localhost:3308

PHP not connection to MySQL server

I am trying to get my PHP pages to connection to a remote server hosting the MySQL database. I can connect via the command line just fine with the same username and password. Below is a simple test file I created. The only thing I've done to the code is remove the password, but I know that's not the issue. Like I said I can connect via the CLI. This is a Linux install. When viewed from the web browser, all I get is an error 500 page. If I comment out the mysqli statement, the page displays the Connected successfully.
<?php
$servername = "12.0.1.170";
$username = "jason";
$password = "";
// Create connection
$conn = mysqli_connect($servername, $username, $password);
// Check connection
if (!$conn) {
/ die("Connection failed: " . mysqli_connect_error());
}
echo "Connected successfully";
?>
Per the php documentation for mysqli_connect()
$link = mysqli_connect("127.0.0.1", "my_user", "my_password", "my_db");
if (!$link) {
echo "Error: Unable to connect to MySQL." . PHP_EOL;
echo "Debugging errno: " . mysqli_connect_errno() . PHP_EOL;
echo "Debugging error: " . mysqli_connect_error() . PHP_EOL;
exit;
}
echo "Success: A proper connection to MySQL was made! The my_db database is great." . PHP_EOL;
echo "Host information: " . mysqli_get_host_info($link) . PHP_EOL;
mysqli_close($link);
Your code appears to be lacking all four parameters required.
You have:
$conn = mysqli_connect($servername, $username, $password);
Perhaps try:
$conn = mysqli_connect($servername, $username, $password, $database);
with a $database='db_name'; value added into your variables section.
There are two possible issues with remote mysql connection:
1. Firewall of the server: You must enable incoming connection on port (for. e.g. 3306).
2. User in mysql: You must have a user created (for e.g. jason in this case)
Try connecting this way
$con = mysqli_connect('localhost','root','','db_name');
if($con)
echo "hell yeah its connected";
else
echo "i m boned"

PHP not seeing mysql.sock from the web

I have a script that connects to a MySQL database in localhost, when I run it from the console it runs just fine, but when I run it from the web, I get this:
Warning: mysqli_connect(): (HY000/2002): No such file or directory in /var/www/html/tests/mysql.php on line 3
Error: Unable to connect to MySQL. Debugging errno: 2002 Debugging error: No such file or directory
I checked my php.ini file and it has the correct location of mysql.sock, the file exist, but php won't connect via web.
Also, I have Fedora Linux with Firewall disabled as well as SELinux, so I have no idea what can be causing this.
This is the test code I'm using:
<?php
$link = mysqli_connect("localhost", "root", "password", "my_db");
if (!$link) {
echo "Error: Unable to connect to MySQL." . PHP_EOL;
echo "Debugging errno: " . mysqli_connect_errno() . PHP_EOL;
echo "Debugging error: " . mysqli_connect_error() . PHP_EOL;
exit;
}
echo "Success: A proper connection to MySQL was made! The my_db database is great." . PHP_EOL;
echo "Host information: " . mysqli_get_host_info($link) . PHP_EOL;
mysqli_close($link);
?>
Any ideas?

Php MySQL Connecting a database via MySQL does not work but ODBC does

I'm trying to connect to a database via MySQL but it does not work. I'm getting the following error:
"Connection failed: No connection could be made because the target machine actively refused it. "
Here's the basic code:
<?php
$servername = "server";
$username = "username";
$password = "password";
// Create connection
$conn = new mysqli($servername, $username, $password);
// Check connection
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
}
echo "Connected successfully";
?>
I can connect to the database from Excel and also via an ODBC connection with the code below but not via MySQL:
<?php
$user = 'username';
$pass = 'password';
$server = 'server';
$database = 'database';
// No changes needed from now on
$connection_string = "DRIVER={SQL Server};SERVER=$server; DATABASE=$database";
$conn = odbc_connect($connection_string,$user,$pass);
if (!$conn){
exit("Connection to the database Failed: " . $conn);
}
echo "Connected successfully";
?>
Any ideas?
You say you can connect with odbc which means you have an SQL Server database, not a Mysql database. If you don't like odbc, pdo is your other option. Mysqli is not an option as its mysql only.
Try this code:
<?php
$link = mysqli_connect('server','username','password','database');
if (!$link) {
echo "Error: Unable to connect to MySQL." . PHP_EOL;
echo "Debugging errno: " . mysqli_connect_errno() . PHP_EOL;
echo "Debugging error: " . mysqli_connect_error() . PHP_EOL;
exit;
}
echo("success");
?>
