How to Install MongoDB on Ubuntu 18.04 LTE

MongoDB is a free and opensource No SQL database written in C++ and used in modern web application development. This tutorial will give you a great understanding of how to install MongoDB on Ubuntu 18.04 LTE.

Perquisites

Before installing MongoDB, we need to ensure that the server is up-to-date. So, let’s first update and upgrade the server:

sudo apt-get update && apt-get upgrade –y

Steps to Install MongoDB on Ubuntu

Step 1 — Adding the MongoDB Repository

MongoDB is included in Ubuntu Package repository by default, but we will use official MongoDB repository since it provides the most up-to-date version of the MongoDB.

So, we will add the official MongoDB repository to our server.

Ubuntu verifies that software packages are signed with GPG keys to ensure the authenticity of the packages. So, we need to first import the key for the official MongoDB repository to ensure it’s authenticity. For that we need to run the following command:

sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv EA312927

Once the keys are imported successfully, you get to see the output:

gpg: Total number processed: 1
gpg:               imported: 1  (RSA: 1)

Now we need to add MongoDB repository details to let advance packaging tool (APT) know the location on the internet from where the packages can be downloaded.

To add MongoDB repository, run the following command:

echo "deb http://repo.mongodb.org/apt/ubuntu xenial/mongodb-org/3.2 multiverse" | sudo tee /etc/apt/sources.list.d/mongodb-org-3.2.list

Once done, update the package list by running the following command:

sudo apt-get update

Step 2 — Installing MongoDB

Since we are done with all the major configuration we can proceed further and install MongoDB on Ubuntu. To install MongoDB, run the following command:

sudo apt-get install -y mongodb-org

The command above will install all the latest stable packages required to run the MongoDB No SQL database on Ubuntu Server.

Now let’s start the MongoDB server using systemctl command.

sudo systemctl start mongod

Run the following command to check whether the MongoDB service started successfully or not:

sudo systemctl status mongod

If everything works properly, you get to see the following output:

● mongodb.service - High-performance, schema-free document-oriented database
   Loaded: loaded (/etc/systemd/system/mongodb.service; enabled; vendor preset: enabled)
   Active: active (running) since Mon 2019-02-08 19:27:20 EDT; 1min 30s ago
 Main PID: 4093 (mongod)
    Tasks: 16 (limit: 512)
   Memory: 47.1M
      CPU: 1.224s
   CGroup: /system.slice/mongodb.service
           └─4093 /usr/bin/mongod --quiet --config /etc/mongod.conf

Now we need to enable the MongoDB that will allow the service to start automatically every time the server is restarted. It can be achieved by issuing the following command:

sudo systemctl enable mongod

Step 3 — Adjusting the Firewall

This is completely optional if you want to adjust your firewall. But if you run your web application and database on the same server, it is highly recommended that you adjust your firewall.

I assume you have completed your initial server setup and enabled the firewall on your server.

The first and the foremost thing is to allow access to the MongoDB on its default port 27017. To allow that run the following command:

sudo ufw allow 27017

To allow access to the MongoDB server from the trusted sources like another web application hosting server, run the following command:

sudo ufw allow from your_other_server_ip/32 to any port 27017

To verify the changes, run:

sudo ufw status

You get to see the following output:

Status: active

To                         Action      From
--                         ------      ----
27017                      ALLOW       Anywhere
OpenSSH                    ALLOW       Anywhere
27017 (v6)                 ALLOW       Anywhere (v6)
OpenSSH (v6)               ALLOW       Anywhere (v6)
