MongoDB is a powerful and flexible NoSQL database that stores data in a flexible JSON-like format. It is widely used in modern web applications for its high performance, scalability, and ease of use. However, you may encounter issues when trying to access MongoDB over HTTP on the native driver port. In this guide, we will walk you through the steps to fix this issue and access your MongoDB database over HTTP successfully.

Introduction to MongoDB and HTTP
MongoDB typically runs on port 27017 for the native driver connection. This port is designed for use with the MongoDB drivers and tools, not for direct HTTP access. To access MongoDB over HTTP, you need to enable the REST API or use a third-party tool such as MongoDB HTTP Interface.
This guide assumes you have already installed and configured MongoDB on your system. If you haven't, follow the official MongoDB installation guide for your platform.
Common Issues and Solutions
Issue 1: Native Driver Port Not Supporting HTTP
By default, MongoDB's native driver port (27017) does not support HTTP access. To fix this issue, you can enable the REST API or use a third-party tool.
Solution 1: Enable REST API
To enable the REST API for MongoDB, follow these steps:
Edit your MongoDB configuration file (usually located at /etc/mongod.conf or /usr/local/etc/mongod.conf).
Add the following lines to the configuration file:
net:
http:
enabled: true
RESTInterfaceEnabled: true
Save the file and restart MongoDB:
sudo service mongod restart
or
sudo systemctl restart mongod
Now you should be able to access MongoDB over HTTP on port 28017.
Solution 2: Use a Third-Party Tool
There are several third-party tools available that provide an HTTP interface for MongoDB. One popular option is mongo-express, which is a web-based MongoDB admin interface written in Node.js.
To install and use mongo-express, follow these steps:
Install mongo-express using npm:
npm install -g mongo-express
Configure mongo-express by editing the config.js file (located in the mongo-express installation directory).
Start mongo-express by running the following command:
mongo-express
Now you should be able to access MongoDB over HTTP on the default mongo-express port (8081).
Issue 2: Firewall Blocking Access
If you're unable to access MongoDB over HTTP after enabling the REST API or using a third-party tool, it's possible that a firewall is blocking access to the relevant port.
Solution: Configure Firewall to Allow Access
To fix this issue, you need to configure your firewall to allow incoming connections on the relevant port (28017 for the REST API, or the port used by your third-party tool).
Follow the official MongoDB documentation on configuring firewalls for MongoDB to allow access to the required port.
Issue 3: Incorrect Connection URI
If you're still unable to access MongoDB over HTTP, it's possible that you're using an incorrect connection URI.
Solution: Use the Correct Connection URI
When connecting to MongoDB over HTTP, make sure to use the correct connection URI:
- For the REST API:
http://<your-server-ip-address>:28017 - For a third-party tool: Refer to the tool's documentation for the correct connection URI.
Replace <your-server-ip-address> with the IP address or domain name of your MongoDB server.
FAQs
1. Can I access MongoDB over HTTPS?
Yes, you can access MongoDB over HTTPS by configuring an SSL/TLS certificate for your MongoDB server. Follow the official MongoDB documentation on configuring SSL/TLS for MongoDB.
2. How can I secure my MongoDB REST API?
To secure your MongoDB REST API, you can use authentication and authorization mechanisms. Follow the official MongoDB documentation on enabling authentication for MongoDB.
3. Which third-party tools can I use for accessing MongoDB over HTTP?
There are several third-party tools available that provide an HTTP interface for MongoDB, such as:
4. Can I use the MongoDB native driver to connect to MongoDB over HTTP?
No, the MongoDB native driver is designed to connect to MongoDB over the default port (27017) and does not support HTTP access. To access MongoDB over HTTP, you need to enable the REST API or use a third-party tool.
5. Can I change the default port for the MongoDB REST API?
Yes, you can change the default port for the MongoDB REST API by updating the net.http.port setting in your MongoDB configuration file:
net:
http:
enabled: true
RESTInterfaceEnabled: true
port: <your-desired-port>
Replace <your-desired-port> with the desired port number.
