Enabling and disabling remote access to a MongoDB Server

In MongoDB, the remote access is enabled by default. Remote access to MongoDB server can be controlled by the variable “bind_ip” specified in the configuration file mongodb.conf.

In MongoDB, the variable “bind_ip” is not set. So a MongoDB client, accessed from any remote machine can be connected to the MongoDB server by default.

The information provided in this article is tested with MongoDB 2.2.2 in Ubuntu 12.04 LTS.

Disabling remote access ( Localhost only access ) to MongoDB Server

• Open  the file mongodb.conf and add the line bind_ip = 127.0.0.1
• Restart MongoDB service [ In Ubuntu : $sudo service mongodb restart ]
• Now remote access is disabled

Testing remote access to MongoDB Server

Installing MongoDB client in remote machine ( Ubuntu 12.04 )
