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

Ubuntu 16.04 -> MongoDB shell version: 2.6.10

For me the following works:

bind_ip = [127.0.0.1;X.X.X.X]

Notice I have a ; not ,

Answer 2

Wrap the comma-separated-Ips with brackets works in mongo 3.2.7 for me:

bindIp = [127.0.0.1, 192.168.184.155, 96.88.169.145]

Answer 3

I successfully added a second ip on my version 3.2 service using a comma, no spaces and an FQDN

net:
  port: 27017
  bindIp: localhost,dev-2.office.sampleorg.com

Answer 4

For those who still wondering - problem is not in the syntax, but the addresses you put in.

Answer 5

With the following version of MongoDB: MongoDB shell version v3.6.10

Reproducing Problem: When [127.0.0.1,xxx.xxx.xxx.xxx] is used we get the following error. Scalar option 'net.bindIp' must be a single value try 'mongod --help' for more information

Analysis This is because, according to MongoDB Documentation: https://docs.mongodb.com/manual/reference/configuration-options/#net.bindIP

net.bindIP is of type "string".

Solution for binding multiple IP Addresses

bindIp: "127.0.0.1,xxx.xxx.xxx.xxx"

Note: No spaces after commas

Answer 6

In my case the solution was to put the comma separated IP and without any spaces.

bind_ip=192.168.2.29,127.0.0.1
#port = 27017

That way worked:

2018-10-02T07:49:27.952+0000 I CONTROL  [initandlisten] options: { config: "/etc/mongodb.conf", net: { bindIp: "192.168.2.29,127.0.0.1", unixDomainSocket: { pathPrefix: "/run/mongodb" } }, storage: { dbPath: "/var/lib/mongodb", journal: { enabled: true } }, systemLog: { destination: "file", logAppend: true, path: "/var/log/mongodb/mongodb.log" } } 2018-10-02T07:49:27.954+0000 I -    [initandlisten] Detected data files in /var/lib/mongodb created by the 'wiredTiger' storage engine, so setting the active storage engine to 'wiredTiger'.

Mongo 3.6.3 here.
