How to set mongod.conf bind_ip with multiple ip address

Question

I am a newbie for setting up the server environment and mongoDB. This may sounds something really simple, however, I really need your help on it.

I am trying to conn

Answer 1

Amazon-linux2 | Cent OS | MongoDB shell version: 3.0.15

This is how it needs to be done in the latest config

#network interfaces
net:
  port: 27017
  bindIp: [xxx.xxx.xxx.xxx,127.0.0.1]  # Listen to local interface only, comment to listen on all interfaces.

Cheers!!

Answer 2

With MongoDB server version: 3.6.8 plain comma separated list worked for me. With or without spaces after comma.

bind_ip = 127.0.0.1, 192.168.0.104
bind_ip = 127.0.0.1,192.168.0.104

However, adding enclosing in [] fails with following error in MongoDB log

bind_ip = [127.0.0.1,192.168.0.104]
getaddrinfo("[127.0.0.1") failed: Name or service not known

bind_ip = [127.0.0.1, 192.168.0.104]
getaddrinfo("[127.0.0.1") failed: Name or service not known

Answer 3

You can do that by:

bindIp: [172.31.60.184,127.0.0.1]

Remember to not put a space after the comma.

Answer 4

The case in mongodb version 3.6 on my Ubuntu16.04 LTS is that you do not need to put the IP addresses in the square brackets "[]". Delete the space after the comma solve the failed connection problem in the mongod log (/var/log/mongodb/mongod.log)

NETWORK  [initandlisten] getaddrinfo(" xxx.xxx.xxx.xxx") failed: Name or service not known

After modify the bindIp: 127.0.0.1 to bindIp: 127.0.0.1,xxx.xxx.xxx.xxx (notice no comma between IPs), the host IP is listening as below:

xxx@xxxx:/var/log/mongodb$ sudo netstat -plnt |egrep mongod
tcp        0      0 xxx.xxx.xxx.xxx:27017   0.0.0.0:*               LISTEN      30747/mongod    
tcp        0      0 127.0.0.1:27017         0.0.0.0:*               LISTEN      30747/mongod
