connecting to mongo replica set from EC2

Question

I am trying to connect to a mongo replica set using PHP,

my code looks like this:

$options = array(
                'replicaSet' => 'Repset',
                'readPreference' => 'primaryPreferred',
        );
        $connection = new MongoClient("mongodb://ip-10-1-2-3.ec2.internal:27017,ip-10-1-2-4.ec2.internal:27017/", $options);

When I do this I get an error back:

No candidate servers found

if I simplify the connect string to :

$connection = new MongoClient("mongodb://ip-10-1-2-4.ec2.internal:27017/");

Then it connects to the server, but this is not the right way, given I am using replica Sets

What am I doing wrong, the connect script seems right but obviously isn't.

Would appreciate any help.

您是否尝试过删除$ options之前的空格？
