How to Install MongoDB on Ubuntu 20.04 LTS

In this tutorial, We are going to Perform How to Install MongoDB on Ubuntu 20.04 LTS or any other cloud platform like Amazon EC2, Azure VM, Google Compute Cloud, etc., with preinstalled ubuntu 20.04 LTS,


MongoDB is a free and open source document-oriented NoSQL and cross-platform database server used for high volume data storage.It uses JSON like documents which makes the database very flexible and scalable. MongoDB is a high-performance database program, used by one of the biggest companies in the world like Facebook,Google, Adobe,SAP, TrendMicro, Verizon, BarClays .etc.

1. Import MongoDB Public GPG Key

Once GPG key imported, Add the MongoDB official APT repository in /etc/apt/sources.list.d/mongodb-org-4.2.list using below command as per version of Ubuntu

update the system package using below command,

$ sudo apt-get update

3. How to Install MongoDB on Ubuntu 20.04 LTS

Using above commands we have added apt repository for MongoDB 4.2 community Edition, below is command to install MongoDB,

sudo apt-get install -y mongodb-org

Start the MongoDB service

sudo systemctl start mongod

Now check to see if the service is running:

 sudo systemctl status mongod


● mongod.service - MongoDB Database Server
Loaded: loaded (/lib/systemd/system/mongod.service; disabled; vendor preset: enabled)
Active: active (running) since Thu 2020-06-25 04:23:25 UTC; 9s ago
Main PID: 1089445 (mongod)
Memory: 73.7M
CGroup: /system.slice/mongod.service
└─1089445 /usr/bin/mongod --config /etc/mongod.conf

Created symlink /etc/systemd/system/ → /lib/systemd/system/mongod.service.

By default, MongoDB is listening on only:

Open MongoDB configuration file /etc/mongod.conf and change bindIp by adding required

sudo nano /etc/mongod.conf

By default MongoDB accepts connection from localhost only for security reason. Change the bindIp from to OR you can add any IP those you want to give access.

# network interfaces  net:  port: 27017  bindIp:


 # network interfaces 
       port: 27017   
       bindIp: # to bind to all interfaces

Reload the system daemon to apply changes

sudo systemctl daemon-reload

3. Configuring MongoDB administrator username

Next, Set up MongoDB administrator username and password first we need to open the MongoDB shell, type in:


Inside the mongo shell type this command to switch to the admin database:

 > use admin

Now let’s create the administrator username and set a password for the username:

 > db.createUser({user:"fosstechnix", pwd:"fosstechnix@123", roles:[{role:"root", db:"admin"}]})
 Successfully added user: {         
        "user" : "fosstechnix",         
         "roles" : [                 
          "role" : "root",                         
          "db" : "admin"                 

Type this command in the shell to exit the shell:

 > exit

4. Enable MongoDB authentication

Open /lib/systemd/system/mongod.service with nano:

 sudo nano /lib/systemd/system/mongod.service

On the ExecStart line add a new option argument –auth, the line should look like this:

 ExecStart=/usr/bin/mongod --quiet --auth --config /etc/mongod.conf

press Ctrl+O to save and press Ctrl+X to close the file.

Restart MongoDB so the changes take effect:

 sudo systemctl restart mongod

Now connect to the MongoDB shell using this command:

 mongo -u fosstechnix -p --authenticationDatabase admin

You’ll get prompted for a password, enter the password you set above. Once you are inside the shell verify you’re authenticated with the administrator user we created by issuing this command:

 > db.runCommand({connectionStatus : 1})


        "authInfo" : {                 
       "authenticatedUsers" : [                         
                       "user" : "admin",
                        "db" : "admin"                         
                        "authenticatedUserRoles" : [                         
                         "role" : "root",                                 
                         "db" : "admin"                         
                      "ok" : 1
