Question
How to set up bindIp for a replica set?

Asked by Prithvish Baidya
I am using the Ubuntu 18.04 MongoDB one click installation droplet. I have setup three droplets, and want to set up a replica set. I was trying to follow some tutorials:
[and here] (https://www.digitalocean.com/community/tutorials/how-to-implement-replication-sets-in-mongodb-on-an-ubuntu-vps)
I am stuck at setting a bindIp, and whenever I add the IP of my other droplets to bindIp, mongod won’t start, failing with this error:
Mar 31 15:52:01 db3.muhive.com systemd[1]: mongod.service: Main process exited, code=exited, status=48/n/a
Mar 31 15:52:01 db3.muhive.com systemd[1]: mongod.service: Failed with result 'exit-code'.
To be clear, this works:
# network interfaces
net:
port: 27017
bindIp: 127.0.0.1
but this doesn’t
# network interfaces
net:
port: 27017
bindIp: 127.0.0.1,db1.munhive.com,db2.munhive.com,db3.munhive.com
Pinging each of those individually does work though. How do I set this up? Do I need to configure a private network?

Hi @deformercoding
We have documentation to configure remove access for mongodb, Please feel free to check it out:
In the /etc/mongod.conf file make changes to bindIP as below to three mongodb nodes when you are setting up replication.
In mongodb1 server
In mongodb2 server
In mongodb3 server
Once you made these changes, restart mongod service on all 3 nodes.
Always when you are binding to a non-localhost, please make sure to secure the database by enabling authentication.
Hope this helps!
