Target machine actively refuses mysqli database connection - php

Question

I'm in the process of implementing a system for database table replication. I'm aware of the latter MySQL technique but I couldn't get it working. What I have now is essentially a preliminary implementation.
This is the code I have thus far.
//This is where DBHandler is defined
$documentRoot=$_SERVER['DOCUMENT_ROOT'];
require_once($documentRoot."/Classes/DBHandler.php");
$src_controller = new DBHandler();
$query = "SELECT * FROM table";
$temp = $src_controller->select($query);
//Convert temporary database contents into usable result
while($rowObject=mysql_fetch_object($temp)){
$result[]=$rowObject;
}
//Create database handler to handle database
$dest_controller = new mysqli("ip address", "user", "password", "database name");
if($mysqli->connect_errno){
$errorMessage = sprintf("'%s'", $mysqli->connect_error);
echo $errorMessage;
}
else{
$dest_controller->query("DELETE * FROM table");
//Processing of data goes here
foreach($result as $item){
//Create query to insert individual records
$start = "INSERT INTO table(field1, field2...) VALUES (";
$end = sprintf("'%s', %d, %d, %f, %f)", field1, field2...);
$start .= $end;
//Database handler uses $start to insert record
$dest_controller->query($start);
}
$dest_controller->close();
}
The database being read from is on a different server from the one being written to. I tried checking the host for the target database with the command "SHOW VARIABLES WHERE Variable_name = 'hostname'" and wound up with a site that just gives a "sorry, wrong page or we've moved" page. What's more is that the port number I see in the URL doesn't match up with what the "SHOW VARIABLES WHERE Variable_name = 'port'" command gives me. The latter command says 3306.
I'm not really sure what to do. We use cPanel X to connect to the database and there's an option to allow select IPs remote access to this database. I'm positive I granted access to the right addresses but this accomplished nothing.
Is this some kind of issue with the host or did I not use the right IP address for connection when I created the mysqli object?

Answer 1

If the MySQL port open on that server? Check with this:
telnet yoursever.address.com 3306
If telnet doesn't connect, then the port is blocked and you will need your hosting provider to open it up.
