How to add External network Node(Seconadry Replica set) in my Replication?

[Ketul]

Hie to All,

I want to create replication on different network for fault torlerance. Here below i have mention the  scenario.

I have  two system both are in LAN,  my system contains two node one primary replica and another secondary and another pc has ip 192.168.0.58. I have to make this has secondary replica.

This is my secondary Replica config file contents:

dbpath=d:\Data\db\

logpath=d:\Data\log\mongo.log

logappend=true

port = 27017

replSet = replicaset

 

bind_ip = 127.0.0.1

When i add to add this replica in my system using this below command on mongo shell  then its give me following error.

replicaset:PRIMARY> rs.add("192.168.0.58:27017")

{

        "errmsg" : "exception: can't use localhost in repl set member names exce

pt when using it for all members",

        "code" : 13393,

        "ok" : 0

}

Any one has solution about this.

Thanks in Advance

Hi Ketul,

The error message indicates that you already have one or members in your replica set added as "localhost":

        "errmsg" : "exception: can't use localhost in repl set member names except when using it for all members",

Since localhost is a special loopback address referring to the local network interface, you cannot use this for members of a replica set on different server -- each server's "localhost" would be referring to a different server.

If you provide the output of your `rs.conf()` someone can suggest how to reconfigure .. but it might be easier to follow the tutorial:

 http://docs.mongodb.org/manual/tutorial/deploy-replica-set/

You will also need to remove the bind_ip restriction from your config file:

 bind_ip = 127.0.0.1

All members of the replica set need to talk to each other over a network interface, so you need to bind to something other than 127.0.0.1 and allow appropriate connections via your firewall.
