MongoDB replication help me figure it out?

Question

MongoDB

I check and get:

rs0:PRIMARY> rs.status()
{
        "set" : "rs0",
        "date" : ISODate("2013-11-15T08:47:30Z"),
        "myState" : 1,
        "members" : [
                {
                        "_id" : 0,
                        "name" : "IP:27017",
                        "health" : 1,
                        "state" : 1,
                        "stateStr" : "PRIMARY",
                        "uptime" : 186686,
                        "optime" : Timestamp(1384505195, 1),
                        "optimeDate" : ISODate("2013-11-15T08:46:35Z"),
                        "self" : true
                },
                {
                        "_id" : 1,
                        "name" : "IP:27017",
                        "health" : 1,
                        "state" : 1,
                        "stateStr" : "PRIMARY",
                        "uptime" : 822,
                        "optime" : Timestamp(1384322313, 1),
                        "optimeDate" : ISODate("2013-11-13T05:58:33Z"),
                        "lastHeartbeat" : ISODate("2013-11-15T08:47:29Z"),
                        "lastHeartbeatRecv" : ISODate("1970-01-01T00:00:00Z"),
                        "pingMs" : 0
                },
                {
                        "_id" : 2,
                        "name" : "IP:27017",
                        "health" : 1,
                        "state" : 1,
                        "stateStr" : "PRIMARY",
                        "uptime" : 822,
                        "optime" : Timestamp(1384322411, 1),
                        "optimeDate" : ISODate("2013-11-13T06:00:11Z"),
                        "lastHeartbeat" : ISODate("2013-11-15T08:47:28Z"),
                        "lastHeartbeatRecv" : ISODate("1970-01-01T00:00:00Z"),
                        "pingMs" : 0
                }
        ],
        "ok" : 1
}

Why are all members of the replica PRIMARY, how to make one master and two slaves?

Answer 1

In general, for those who are interested:
On the main (master) in the shell, deleted the members of the replica, restarted mongo (otherwise, when adding, he cursed that such machines had already been added).
Restarted mongo on other machines.
From the main one, I added one host at a time and checked it from two machines, then added a third machine. Set priorities.
As I understand it, the whole cant was that I added all the members of the replica at once, and when I did one at a time and after each rs.reconfig everything worked.

Answer 2

Try to initialize.

rs.initiate()

Answer 3

Did. These are the conclusions after it. If I do it again I get "already initialized" and nothing else.

Answer 4

It seems to me that the replica is not assembled correctly. Try to parse it, then on one first member do rs.initiate() and after that add the rest via rs.add()

Answer 5

According to this document, it was made.
Let's go through the steps:
I edit the config file on each machine. Well, accordingly, I check the availability of cars for each other.
Then on the first machine I do rs.initiate() and then rs.add() and add the other two.
