MongoDB Configuration – How to Set Multiple bindIp Addresses in Mongod Config?

mongodb-3.4

I have the following config file:

net:
  bindIp: 127.0.0.1
  port: 27017

storage:
  dbPath: c:\mongoDATA\db
  journal:
    enabled: true

##systemLog:
 ## destination: file
 ## path: C:\mongoDATA\log\mongodb.log   
 ## logAppend: true

this works, but when I try to add multiple ports like:

bindIp: 127.0.0.1, 192.168.10.115
or
bindIp: "127.0.0.1, 192.168.10.115"
or
bindIp: [127.0.0.1, 192.168.10.115]

with or without the space after the comma it doesn't. Could someone provide the write syntax? Thanks (using 3.6 community)

without a space after the comma, AND the ip address has to present

MongoDB – Service Mongod Fails After Adding Security.keyFile in Config File

Use full path for keyfile. Don't use ~ -character there. Your mongod is started (probably) with user 'mongod' and that user don't have home directory.

Additionally keyfile must be have chmod 0400 and ownership same than user who run mongod process (mongod).

MongoDB – How to Set Up User Authentication Without Admin Database Access

Not need. You just give user needed rights to the wanted non-admin database. User can use admin database as authentication database even user doesn't have read/write access to admin database.

use products
db.grantRolesToUser("productsUser",[ "readWrite" ])

grantRolesToUser documentation.

UPDATE

Let's create mongodb instance with --auth. Login as admin, create user what can readWrite ONLY test -db, authenticate with that user, check can use list admin database collections and what this user can do with test database.

#> mlaunch init --single --auth
launching: mongod on port 27017
Username "user", password "password"
#> mongo -u user -p password admin
MongoDB shell version v3.4.6
connecting to: mongodb://127.0.0.1:27017/admin
MongoDB server version: 3.4.6
Mongo> db.createUser({user:"test", pwd:"testpwd", roles:[{role:"readWrite", db:"test"}]})
Successfully added user: {
    "user" : "test",
    "roles" : [
        {
            "role" : "readWrite",
            "db" : "test"
        }
    ]
}
Mongo> db.auth("test","testpwd")
1
Mongo> db

Mongo> show collections
