-Summary: mysqlnd: host cannot be a hostname
+Summary: mysqlnd: host cannot be "localhost" when connecting to
tcp port
Status: Bogus
Type: Bug
Package: MySQL related
Operating System: Ubuntu 10.04
PHP Version: 5.3.3
New Comment:
Seriously?
http://www.php.net/manual/en/ref.pdo-mysql.connection.php gives two
examples:
mysql:host=localhost;port=3307;dbname=testdb
mysql:unix_socket=/tmp/mysql.sock;dbname=testdb
And my DSN (constructed by Zend Framework) follows the first example.
Where does it say I have to define the unix socket in php.ini if I
intend to connect using the tcp port?
Here's the fix:

Tell PHP where your mysql.sock file is via the DSN or
pdo_mysql.default_socket in
the php.ini file and your error will go away. Your conclusion is way
off.

Description:
------------
With PDO_MYSQL, if PHP is linked with mysql client libraries (instead of
mysqlnd), the DSN can contain a host parameter with a hostname, e.g.,
host=localhost.
However, with mysqlnd, the host has to be an ip address, e.g.,
host=127.0.0.1. This occurs for '--with-mysqli=mysqlnd' or
'--with-pdo-mysql=mysqlnd'. It appears mysqlnd wants to use a Unix
socket even though the port is explictly specified,
This backward incompatibility surprises users migrating from php 5.2.x
and find their apps suddenly can't connect.
MySQL 5.1.41
Test script:
---------------
>From Zend Framework 1.10.6:
$_isConnected = @mysqli_real_connect(
$this->_connection,
$this->_config['host'],
$this->_config['username'],
$this->_config['password'],
$this->_config['dbname'],
$port
);
Expected result:
----------------
Expect it to connect.
Actual result:
--------------
Warning: PDO::__construct() [pdo.--construct]: [2002] No such file or
directory (trying to connect via unix:///tmp/mysql.sock) in
/var/www/libs/Zend/Db/Adapter/Pdo/Abstract.php on line 129
