how to convert mongodb(2.4.10) startup2 to primary

Question

I have standalone bitnami mongodb(2.4.10). The output of rs.status() command is below :

rs.status()
{
    "set" : "test",
    "date" : ISODate("2015-11-13T08:07:41Z"),
    "myState" : 5,
    "members" : [
        {
            "_id" : 0,
            "name" : "10.11.208.182:27017",
            "health" : 1,
            "state" : 5,
            "stateStr" : "STARTUP2",
            "uptime" : 1024,
            "optime" : Timestamp(0, 0),
            "optimeDate" : ISODate("1970-01-01T00:00:00Z"),
            "errmsg" : "initial sync need a member to be primary or secondary to do our initial sync",
            "self" : true
        }
    ],
    "ok" : 1
}

How can I change it to primary?

I have to use replica set in standalone server. This server was launched by bitnami mongodb)2.4.10) AMI.

I am new for mongodb. Any help much appreciated.

I Don't have any replica set member. It was standalone server. rs.conf ()

dwandra:STARTUP2> rs.conf() { "_id" : "dwandra", "version" : 93960, "members" : [ { "_id" : 0, "host" : "10.11.208.182:27017" } ] }
