    hi! please, eva2008, help me, i'm stuck
    im from ukraine sorry for bad english.
    CentOS 6.7 64bit, installed stable last centminmod
    mariadb 10

    everything works fine except remote connection to mysql DB via mysqli or PDO:
    Code:
    $mysqli  = new mysqli($host, $user, $pass, $db);
if ($mysqli->connect_error) {
    die('Error (' . $mysqli->connect_errno . ') '
            . $mysqli->connect_error);
}
if (mysqli_connect_error()) {
    die('Error (' . mysqli_connect_errno() . ') '
            . mysqli_connect_error());
}
echo 'SUccess... ' . $mysqli->host_info . "\n";
$mysqli->close();
    this code works fine with localhost, but i need to connect to remote DB to use SMS sending service.
    the code above and the whole module works well on other shared hosting, but on VPS with centminmod i'm in trouble((

    i also tried to add port 3306 and socket directli to new mysqli($host, $user, $pass, $db, $port, $socket);
    but this not helped.

    Centmin Mod LEMP stack installs CSF Firewall out of the box, so to be able to remotely connect to external servers, you need to whitelist and allow the remote IP address see the info below:

    great! thanks a lot!!

    everything i need was:
    1. csf -a XX.XXX.XXX.XXX
    (where xxx.xxx... - is IP of remote host what i was trying to connect to)
    2. csf -r
    (is to restart the firewall)

    FYI you don't need to restart csf firewall when adding or denying ips :)
