Google Cloud Platform - Can't connect to mongodb

Question

Just installed mongodb using click-to-deploy in google cloud platform. I have another project, for which I created the mongodb database, where my web application runs. Do I have to open some port or configure something?

Solution 1

As the other answers in this thread suggest, mongod daemon is listening on TCP port 27017. Therefore, you will need to add a firewall rule on Compute Engine firewall for this port and protocol. This can be done using Google Cloud console or using gcloud command tool:

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

It is recommended to use target tag with the firewall rule and use this target tag to specify what VM instances the firewall rule should be applied to.

Solution 2

Adding the port in the firewall is not enough. By default the host bind to 127.0.0.1 which needs to be changed to 0.0.0.0 Make changes in the file sudo nano /etc/mongod.conf inside the instance Look for the term bindIp change it to 0.0.0.0 and restart mongodb You will be able to connect to the mongo db now

This is correct. The accepted answer should be "merged" with this one. In my Windows Google Compute Engine, I needed to open the same port in Windows Firewall too.
