How to Install MongoDB on an Alibaba Cloud ECS Instance

A Bit about MongoDB

Some of the Advantages of MongoDB

  • Best way to work with data: MongoDB’s flexible document data model makes working with data more intuitive, no matter whether you’re building an app from scratch or updating an existing one.
  • Put data where you need it: MongoDB lets you control where data is placed globally in a premise way so that you can ensure fast performance anywhere as well as compliance with regulations more easily.
  • Run anywhere: Complete deployment flexibility with seamless data migrations, and also build a ubiquitous data layer from mainframes to the public cloud and everywhere in between.

Using MongoDB on Alibaba Cloud


  1. You must have an Alibaba Cloud Elastic Compute Service (ECS) activated. If you are a new user or new to ECS, you can get Free Credits in your Alibaba Cloud account. If you don’t know about how to setup your ECS instance, you can refer to this tutorial or check quick-start guide.
  2. You should setup your server’s hostname.
  3. You have access to the VNC console in your Alibaba Cloud or the SSH client installed in your PC.
