Step 1 - Adjusting the FirewallĪssuming you followed the prerequisite initial server setup tutorial and enabled a UFW firewall on your server, your MongoDB installation will be inaccessible from the internet. To do this, follow our tutorial on How To Secure MongoDB on Ubuntu 20.04.Īdditionally, you can consult the official MongoDB recommendations on security hardening as well as their security checklist. Lastly, while it isn’t required to complete this tutorial, we strongly recommend that you secure your MongoDB installation by creating an administrative user account for the database and enabling authentication. However, Steps 1 and 2, which describe the actual procedure for enabling remote connectivity on the database server, will work regardless of what operating system the remote machine is running. For simplicity, this tutorial assumes that this machine is another Ubuntu 20.04 server, with a non-root administrative user and a UFW firewall configured following our initial server setup guide for Ubuntu 20.04.
A second computer from which you’ll access your MongoDB instance. You can install this version by following our tutorial on How To Install MongoDB on Ubuntu 20.04. This tutorial assumes that you have MongoDB 4.4 or newer installed. Set this up by following our initial server setup guide for Ubuntu 20.04. This server should have a non-root administrative user and a firewall configured with UFW. Then, as a final step, you’ll test that your remote machine is able to make the connection to your database successfully. To do this, you’ll update your firewall rules to provide the remote machine access to the port on which MongoDB is listening for connections and then update its configuration file to change its IP binding setting. In this tutorial, you will configure a MongoDB installation to securely allow access from a trusted remote computer. If you want to manage MongoDB remotely or connect it to a separate application server, there are a few changes you’d need to make to the default configuration. By default, it only allows connections that originate on the same server where it’s installed. MongoDB is a document-oriented database used in many modern web applications.
