How can mongodb use ip instaed of hostname in Replica Set?

[realzyy]

I can see the hostname in the built-in replica set admin UI like this:

Member id Up cctime Last heartbeat Votes State Status optime skew
my031049.sqa.cm4:27017 (me) 0 1 18 hrs 1 PRIMARY 4cb66f79:1


But I would like see my host in ip mode. Does anyone know how to deal
with it?

Currently, the UI and other admin utilities show the "name" used when
you created the set. So it you use hostnames then you see hostname, if
you use IP's then you will see IP's.

Feel free to add an enhancement request in Jira to change the display
options

I tried. If there is only one node in the ReplicaSet, it will use
hostname.
It appears that the first node (master) will always use hostname.
This causes some problem in my case. What should I do?

See http://jira.mongodb.org/browse/SERVER-1813

if you start the replicaSet with an empty conf, mongo 1.6.X uses the
system gethostbyname()

Try with a conf using IPs

Sorry for my late reply.

As your suggestion, I use bind-ip to start ReplicaSet. But it
encounters another problem when rs.initiate() is executed. Error
infomation is like this:
rs.initiate()
{
"startupStatus" : 4,
"info" : "ttttt",
"errmsg" : "all members and seeds must be reachable to
initiate set",
"ok" : 0
}

Maybe bind-ip can't be used in ReplicaSet?

No, don't use bind_ip, specify the ips you're using in rs.initiate.  See http://www.mongodb.org/display/DOCS/Replica+Set+Configuration#ReplicaSetConfiguration-TheReplicaSetConfigObject and run rs.initiate(<config>).  Each member's host field should be an IP.
