Error establishing a database connection

An unspecified error occurred in the native sql server connection component.

Once the instance is launched, it may take a few minutes before it is ready to connect. Check your instance to make sure it is running and has passed its status checks.

Check the network access control list (ACL) for the subnet.Network ACLs must allow inbound traffic from your local IP address through port 22 (for Linux instances) or port 3389 (for Windows instances). They must also allow outgoing traffic routed to ephemeral ports (1024-65535).

… Expecting: ANY PRIVATE KEY, the file in which the private key is stored is incorrectly configured. If the private key file ends in .pem, it is possible that it is still incorrectly configured. One possible cause for an incorrectly configured private key file is a missing certificate.

If you connect to the instance using SSH and get the errors Host key not found in [directory], Permission denied (publickey), Authentication failed, permission denied or Connection closed by [instance] port 22, check that you are connecting with the proper username for the AMI and that you have specified the proper private key file (.pem) for the instance.

Error del servidor sql 2

Tenga en cuenta que en todos los servidores >=Windows 7, un nombre de host “localhost” creará una búsqueda muy costosa (~1 segundo). Esto se debe a que desde Windows 7, el archivo de hosts no viene con un localhostanymore preconfigurado127.0.0.1Así que, si nota una larga creación de conexión, pruebe con “127.0.0.1” en su lugar.

Hay un parámetro de puerto separado, a diferencia de mysql_connect. Sin embargo, el uso de host:port en el parámetro host sí funciona.Hay una advertencia. Si el host es ‘localhost’ entonces el puerto es ignorado, ya sea que uses un parámetro de puerto o la sintaxis implícita que mencioné anteriormente. Esto se debe a que ‘localhost’ hará que se utilicen sockets unix en lugar de TCP/IP.

Si quieres conectarte a través de un puerto alternativo (distinto al 3306), como podrías hacer cuando uses un túnel ssh a otro host, usar “localhost” como nombre de host no funcionará. Usar 127.0.0.1 funcionará.    Aparentemente, si se especifica el host como “localhost”, el constructor ignora el puerto especificado como argumento del constructor.
