Can't Access MongoDB instance hosted in Google Cloud VM from RoboMongo

Question

I have created a project and deployed MEAN stack by using "Click to Deploy". When I visit <> / 3000 I do see the MEAN page coming from the server. Also I can ssh to that machine and see all the stuff there. I can access MongoDB instance in that way.

I also created a separate VM where I installed Node.JS and MongoDB myself. Both working similar way.

My problem is - I can't access either of the machines from my local RoboMongo Instance neither I can access them from local shell. I had similar issue in aws world and solution was to create security group to permit the mongodb port (27017). So I tried that and added "Firewall rule" under "Network" and allowed that port for all incoming traffics --> as bellow

mongodb communication from outside Source Ranges: 0.0.0.0/0 Allowed Protocols or Ports: tcp:27017 But the issue persists and I can't access the mongodb instance from robomongo or local shell.

Any idea ?

Answer 1

I suggest that you check if your MongoDB is listening on port 27017 by running the following command:

sudo netstat -nap | grep 27017

I suggest also that you try to turn off your IP tables on the VM and try to access maybe a rule is blocking your access. One thing also to check is your bindIp using db.serverCmdLineOpts()

Answer 2

You should config bind_ip = 0.0.0.0 when start mongod eg mongod.conf as folowing

fork = true
bind_ip = 0.0.0.0
port = 27017
quiet = true
dbpath = /srv/mongodb
logpath = /var/log/mongodb/mongod.log
logappend = true
journal = true

and start mongo as this command

sudo mongod --config /etc/mongodb.conf

Now you can connect Mongo on Google cloud VM through external IP with 27017 as port.
