I have weird situation in newly installed server, and it seems that Google can’t help me this time.
I can’t connect to (remote) mysql from my php-code. When I try to connect from command line on the same server the connection succseds.

Could not connect: Can’t connect to
MySQL server on ‘MYSQL.SERVER’ (13)

Here is the code and the connect attempt from the command line

[u1@bosko httpdocs]$ cat  test.php

<?
$link = mysql_connect('MYSQL.SERVER', 'testusersimon', '123456');
if (!$link) {
    die('Could not connect: ' .  mysql_error());
}
echo 'Connected successfully';
mysql_close($link);
?>

[u1@bosko httpdocs]$ mysql -h MYSQL.SERVER -utestusersimon --password=123456

mysql> quit
Bye

I tried running the php script both in mod_php mode and in FastCGI,
check that “/etc/php.d/mysql.ini” shows up in the phpinfo() as well as mysql,mysqli and pdo_mysql sections.

but the result was the same, I know its something simple but I just can’t .
Please help 🙂

Edit:
The problem was with SElinux

setsebool -P httpd_can_network_connect_db=1

Was the solution.

    setsebool -P httpd_can_network_connect=1

    will also be a helpful CLI command to many people visiting this question, as to allow mysql_connet() connections from within HTTP (Apache) requests to a remote MySQL database server, ensure to enable Network Connections from httpd in SElinux usually located in /etc/selinux/config (disabled by default to prevent hackers from attacking other machines using your httpd).
