用db.getMongo();得到的是：127.0.0.1
浏览器中访问：http://127.0.0.1:27017/
得到的是：It looks like you are trying to access MongoDB over HTTP on the native driver port.
但执行下面的代码：
// 连接到mongodb
$m = new MongoClient();
echo "Connection to database successfully";
// 选择一个数据库
$db = $m->mydb;
echo "Database mydb selected";
?>
结果是：
Internal Server Error
The server encountered an internal error or misconfiguration and was unable to complete your request.
Please contact the server administrator at admin@phpStudy.net to inform them of the time this error occurred, and the actions you performed just before this error.

为什么会这样？
