The MongoConnectionException class

(Информация о версии неизвестна, возможно, только в SVN)


Thrown when the driver fails to connect to the database.

There are a number of possible error messages to help you diagnose the connection problem. These are:

  • No server name given.

    This error occurs if you pass in "" as the server name, probably because of an typo with string interpolation, e.g., "$servr" instead of "$server".

  • failed to get host [hostname] or port [portnum] from [server].

    This indicated that the server string was malformed. "[hostname]" and "[portnum]" will be as much as the driver could dicipher of it.

  • Operation in progress

    Connecting to the database timed out.

  • Transport endpoint is not connected

    Generally means that the connection string isn't correct, the driver couldn't even find the database server.

  • couldn't determine master

    Neither server in a paired connection appeared to be master.

  • couldn't get host info for [server]

    This indicated that DNS could not resolve the server address you gave. This could easily be caused by a typo, for example, "server" instead of "$server".

  • Invalid Argument

    This can be caused by attempting to connect to a machine that is up but that the database isn't actually running on. Make sure that you've started the database server before connecting.

  • Permission denied

    This means that the socket could not be opened due to permissions issues. On Red Hat variants, this can be caused by a default setting that does not allow Apache to create network connections. You can override this setting by running:

    $ /usr/sbin/setsebool -P httpd_can_network_connect 1

    then restarting Apache.

If the error message is not listed above, it is probably an error from the C socket, and you can search the web for its usual cause.
