How to Install MongoDB on Ubuntu 20.04 [Step by Step]

MongoDB is an open-source document database for modern web applications. In this article, I will cover step by step guide to install MongoDB on Ubuntu 20.04.

So let’s dive in.

MongoDB installation Steps

Step 1: Installing MongoDB

You can download MongoDB stable version from the ubuntu repository, but it may not be the latest version. To download the latest version, run the following command:

curl -fsSL https://www.mongodb.org/static/pgp/server-4.4.asc | sudo apt-key add -

This command will return OK. Run the following command, which creates a file in the sources.list.d:

echo "deb [ arch=amd64,arm64 ] https://repo.mongodb.org/apt/ubuntu focal/mongodb-org/4.4 multiverse" | sudo tee /etc/apt/sources.list.d/mongodb-org-4.4.list

Now run following commands to update all the packages:

sudo apt update
sudo apt install mongodb-org

Press Y and then ENTER to confirm that you want to install the package. After command finishes, MongoDB installed on your Ubuntu.

Step 2: MongoDB starting and Database Testing

To start the MongoDB service, run following command:

sudo systemctl start mongod.service

To check MongoDB status, run following command:

sudo systemctl status mongod

This command will return following output:

Output
● mongod.service - MongoDB Database Server
     Loaded: loaded (/lib/systemd/system/mongod.service; disabled; vendor preset: enabled)
     Active: active (running) since Tue 2021-05-06 16:27:07 UTC; 2s ago
       Docs: https://docs.mongodb.org/manual
   Main PID: 37128 (mongod)
     Memory: 64.8M
     CGroup: /system.slice/mongod.service
             └─37128 /usr/bin/mongod --config /etc/mongod.conf

If the service is running perfectly, enable the MongoDB service to startup at boot. Run following command:

sudo systemctl enable mongod

To check the database operational or not, you can use the following command.

mongo --eval 'db.runCommand({ connectionStatus: 1 })'

Here, connectionStatus parameter will check the database connectivity and return the value. Parameter 1 is for server, if it is properly working or not.

Output will be:

Output
MongoDB shell version v4.4.0
connecting to: mongodb://127.0.0.1:27017/?compressors=disabled&gssapiServiceName=mongodb
Implicit session: session { "id" : UUID("1dc7f67x-0az5-4864-g9c3-8g2db7ol9g43") }
MongoDB server version: 4.4.0
{
    "authInfo" : {
        "authenticatedUsers" : [ ],
        "authenticatedUserRoles" : [ ]
    },
    "ok" : 1
}

Here, Database is running under port no 27017 and the server address is 127.0.0.1 (localhost).

Step 3: MongoDB Quick Commands
