php无法连接到sql server 2008(使用pdo dblib)

I have a SQL server 2008 R2 (running on Windows server 2008 64bit), which I'm trying to connect from PHP

My PHP server configuration:

CentOS 6.6

PHP 5.5.24 (compiled --with-mssql=/usr/local/freetds --with-pdo-dblib=/usr/local/freetds)

Apache 2.4.12

SELinux is disabled (according to this solution: PDO DBLIB accessing SQL Server 2008 and 2012)

I wrote the following PHP code to connect to the SQL server:

try {
    require "classes/mypdo.class.php";
    $pdo = new MyPDO('dblib:dbname=myDB;host=myServer', 'myUser', 'myPassword');
    $pdo->debug = true;
} catch (PDOException $e) {
    die("Connection failed: {$e->getMessage()}");
}

The connection failed with an error:

Connection failed: SQLSTATE[HY000] Unknown host machine name (severity 2)

I tried other DSN syntaxes like:

$pdo = new MyPDO('dblib:host=192.168.0.10', 'myUser', 'myPassword');
$pdo = new MyPDO('dblib:host=192.168.0.10:1433', 'myUser', 'myPassword');
$pdo = new MyPDO('dblib:host=myServer', 'myUser', 'myPassword');

and many other variations... When I use an IP address instead of DSN the error is:

Connection failed: SQLSTATE[HY000] Unable to connect: Adaptive Server is unavailable or does not exist (severity 9)

/etc/freetds.conf

[global]
tds version = 7.1
dump file = /tmp/freetds.log
timeout = 10
connect timeout = 10
text size = 64512
client charset = UTF-8

[myServer]
host = 192.168.0.10
port = 1433
tds version = 7.1

I suspect that PHP ignoring freetds.conf (can't confirm it).

When I use tsql the connection is working.

tsql -S myServer -U MyUser -P MyPassword
locale is "en_US.UTF-8"
locale charset is "UTF-8"
using default charset "UTF-8"

What is the reason that PHP refusing to connect to the SQL server?

    There are sometimes problems with an setting inside php.ini

    Please try to change:

    mssql.secure_connection = Off
    

    to

    mssql.secure_connection = On
