Zend_Db: How to connect to a MySQL database over SSH tunnel?

Question

如何使用PHP和Zend Framework连接到需要SSH隧道的MySQL数据库？

Answer 1

Just start up SSH tunnel and use the local port as your MySQL port.

For example, you start tunnel as this,

ssh -f user@mysql-server.com -L 3306:mysql-server.com:3306 -N

And you can connect to MySQL like this,

$conn = mysql_connect('localhost', 'mysql_user', 'mysql_password');

For zend_db, you do this,

$config = new Zend_Config(
    array(
        'database' => array(
            'adapter' => 'Mysqli',
            'params'  => array(
                'host'     => 'localhost',
                'dbname'   => 'my_db',
                'username' => 'mysql_user',
                'password' => 'mysql_password',
            )
        )
    )
);

$db = Zend_Db::factory($config->database);

Answer 2

有没有办法设置它在apache2配置或通过Zend创建持久连接，以便它在需要时从服务器连接并保持打开一段时间以防后续呼叫进入？
