In this tutorial, I will teach you how to make a remote Mongodb connection on the Google Cloud Platform

1. Edit mongod.conf

vim /etc/mongod.conf

2. Change bindIP to 0.0.0.0 or add your mongo host IP

         bindIp: 0.0.0.0

or

bindIp: 127.0.0.1 <your mongodb host IP> 

3. Save and restart mongod

sudo systemctl restart mongod

sudo systemctl status mongod

4. After that, go to your Google Cloud Platform console.  and type

gcloud compute firewall-rules create allow-mongodb --allow tcp:27017

and the result is 

allow-mongodb default INGRESS 1000 tcp:27017 False

Now you can remote you mongodb with mongodb client, try this command on your terminal to test connection.

mongo admin -u <mongo user> -p <mongo password> --host <your mongo host IP> --port 27017  

 change the tag <text> with your configuration

 After you install mongodb and get the warning to enable access control. You can follow this step

1. Start MongoDB without access control. (No need, if service already running)

mongod --port 27017

2. Connect to the instance

mongo --port 27017

3. Create the user administrator

> use admin

switched to db admin

> db.createUser(

...   {

...     user: "superman",

...     pwd: "rahasia",

...     roles: [ { role: "root", db: "admin" } ]

...   })

4. Re-start the MongoDB instance with access control

sudo service mongod restart   

5. Add the security.authorization setting to the config file

sudo vi /etc/mongod.conf 

systemLog:
destination: file
path: /usr/local/var/log/mongodb/mongo.log
logAppend: true
storage:
dbPath: /usr/local/var/mongodb
net:
bindIp: 127.0.0.1
security:
authorization: enabled

6. Restart mongodb 

sudo service mongod restart

7. Connect to database

mongo --port 27017 -u "superman" -p "rahasia" --authenticationDatabase "admin"

now the warning has disappeared
