How to install MongoDB on Linux (Ubuntu 16.04)

MongoDB

Currently MongoDB only supports ubuntu 64-bit LTS (long term support). Example 14.04 LTS (trusty) and 16.04 LTS (xenial)

In this article, I install MongoDB Community Edition (free version) on ubuntu 16.04 operating system

Use package .deb to install MongoDB (Recommended)

MongoDB public GPG Key .

2. Create file list for MongoDB.

  • echo “deb [arch = amd64] https://repo.mongodb.org/apt/ubuntu trusty / mongodb-org / 4.0 multiverse” | sudo tee /etc/apt/sources.list.d/mongodb-org- 4 . 0 .list

With Ubuntu 16.04

  • echo “deb [arch = amd64, arm64] https://repo.mongodb.org/apt/ubuntu xenial / mongodb-org / 4.0 multiverse” | sudo tee /etc/apt/sources.list.d/mongodb-org- 4 . 0 .list
