Today, let’s take a look at getting one of the coolest Ubuntu flavors – Ubuntu MATE. Did you know that you could backup your Ubuntu system entirely for installing later?

Getting Ubuntu MATE

There are 2 different ways you can get yourself the Ubuntu MATE experience – installing MATE desktop environment on any of the Ubuntu installations or installing Ubuntu MATE directly into your system.

Installing MATE desktop

This is the easiest way to enjoy the MATE desktop environment. Run the following commands –

sudo apt update
sudo apt install ubuntu-mate-desktop

After the installation is complete, select MATE session.

Voila! It’s Ubuntu MATE (technically)!

Installing Ubuntu MATE

Download the latest installation image file of Ubuntu MATE.

Most of the computers in the world currently now support 64-bit system with 4GB or more RAM, so 64-bit image is the suitable one. However, if your computer is one of the ancient relics of Jurassic age, then go ahead with the 32-bit ISO file.

Downloading the image is complete? Time to make a bootable media. I recommend using USB flash drive as the bootable media.

Now, boot into the Ubuntu MATE installation media and go ahead with the installation process.

Select your keyboard layout.

Choose the installation type. Generally, the normal installation is what you want. Don’t forget to check the 3^rd-party software option.

Time to choose the installation location. You may also need to add an EFI partition if your system uses UEFI instead of the legacy BIOS system.

Select your location.

Enter your credentials.

Wait until the process completes.

Voila! Ubuntu MATE is ready to serve you!

Before starting the installation of MongoDB on Ubuntu. Let’s have a description about MongoDB. MongoDB a type of database in which we deal with document i.e. database which is more scalable and flexible with the queries that you run to get results on specific conditions. MongoDB is a very fast and more easy to use than traditional database.

In this article we will learn how to install and manage MongoDb to use in our Ubuntu 18.04 server. So let’s start by the following steps.

STEP1:  ADDING MONGODB PACKAGE REPOSITORY TO UBUNTU.

The first step for installing MongoDB on Ubuntu is to add repository files of MongoDB. Actually MongoDB is already in the repository in the Ubuntu by default. But the version in the repositories might not be the latest to your requirements. Therefore, to get the latest version of MongoDB, you have to add its repository in the Ubuntu. Following is the process to add official repository key by command.

Command:  

sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv 2930ADAE8CAF5059EE73BB4B58712A2291FA4AD5

After adding repository key into Ubuntu server, then you have to add the repository to your own system. For this do follow the command mentioned below:

Command:

echo "deb [ arch=amd64,arm64 ] https://repo.mongodb.org/apt/ubuntu xenial/mongodb-org/3.6 multiverse" | sudo tee /etc/apt/sources.list.d/mongodb-org-3.6.list

Step 2: Install MongoDB on Ubuntu 18.04

After adding repositories, you have to install MongoDB on Ubuntu, for this purpose follow the instructions by typing the following commands. This will install MongoDB completely on your Ubuntu and you will get access to use MongoDB.

Command:

sudo apt update 
sudo apt install -y mongodb-org

Step 3: Start MongoDB

After the successful installation of MongoDB over Ubuntu, you can now start MongoDB and manage its components. To verify whether MongoDB is running and active, run following command.

Command:

sudo systemctl status mongod

To start MongoDB type

sudo service mongod start

Step 4: Configure Mongo or Open Mongo Shell

When MongoDB is installed, then you can configure database username and passwords for further use. But before configuring username and passwords MongoDB shell has to be in running state or you have to open its shell. So for opening shell run or type the following command.

Command: 

mongo

Step 5:  Use database Admin Mode

After opening the shell, you may need to move or switch to the database admin where you can create users and passwords respectively. For this purpose, just use the command mentioned below.

Command: 

use admin

Step 6:  Create root user for database

Once you are in the database admin mode, now you can create root user for database. This root user will have permission and roles as an admin to the database. To create root user type following command using your own username and password.

Command:

db.createUser({user:"user1", pwd:"adminuser", roles:[{role:"root", db:"admin"}]})

Step 7:  MongoDB authentication

When you done with creating your root user, then after exiting the MongoDB, you can now authenticate this. To authenticate MongoDb use the following command.

Command: 

nano /lib/systemd/system/mongod.serviceExecStart=/usr/bin/mongod --auth --config /etc/mongod.confsystemctl daemon-reload

Step 8: Connect MongoDB after restarting

After complete authentication and restarting of MongoDB, now you have to connect again with the details of username and password, you have created earlier in the creating root user step. Step 8: to connect run the following command.

Command:

to connect MongoDB

mongo -u admin -p admin123 --authenticationDatabase admin

to restart MongoDB*

sudo service mongod restart     

Conclusion:

After following all the guideline, you are now able to install MongoDb repositories in Ubuntu as well as in your system. And using MongoDb to manage and authenticate as well as creating root user. However, you should follow the same procedure to make it accurate. If you face any problem, then leave a message or comment. We will help you in every matter.

• You have the option of making changes to your partition table. Make sure that you don’t delete any important partition, or you’ll end up in a huge loss. Moreover, make sure to create at least 4GB of “swap” file and 16GB (recommended 64GB) of “/” mount point.
• You have to choose your time zone. Select the appropriate location for yourself.
