How to Install and Configure the MongoDB on Linux Mint 20

To Install and Configure the MongoDB on Linux Mint 20

Introduction:

MongoDB is a document-oriented DB that stores data in Jason like documents with a dynamic schema. It means you can store your records without worrying about the data structure such as the number of fields to store values. MongoDB documents are similar to JSON objects. This tutorial will cover the installation and configuration of the MongoDB on Linux Mint 20.

Installation Procedure:

Check the version of OS.

root@linuxhelp:~# cat /etc/os-release
NAME="Linux Mint"
VERSION="20 (Ulyana)"
ID=linuxmint
ID_LIKE=ubuntu
PRETTY_NAME="Linux Mint 20"
VERSION_ID="20"

Add the MongoDB repository by using the following command

root@linuxhelp:~# wget -qO - https://www.mongodb.org/static/pgp/server-4.2.asc | apt-key add -
ok

Create a list file for MongoDB

root@linuxhelp:~# echo "deb [ arch=amd64 ] https://repo.mongodb.org/apt/ubuntu bionic/mongodb-org/4.2 multiverse" | tee /etc/apt/sources.list.d/mongodb-org-4.2.list
deb [ arch=amd64 ] https://repo.mongodb.org/apt/ubuntu bionic/mongodb-org/4.2 multiverse

Run the update command for update the repositary

root@linuxhelp:~# apt update
Hit:1 http://archive.ubuntu.com/ubuntu focal InRelease
Ign:2 http://packages.linuxmint.com ulyana InRelease

Now install MongoDB by using the following command

root@linuxhelp:~# apt install mongodb -y

Once the installation is completed. Start the service of MongoDB

root@linuxhelp:~# systemctl start mongodb

Now enable the MongoDB service

root@linuxhelp:~# systemctl enable mongodb
Synchronizing state of mongodb.service with SysV service script with /lib/systemd/systemd-sysv-install.
Executing: /lib/systemd/systemd-sysv-install enable mongodb

Now enter into the MongoDB shell and create database and user for admin

root@linuxhelp:~# mongo
MongoDB shell version v3.6.8

Now switch to database

> use admin
switched to db admin
>
>
>
> db.createUser({user: "mongodadmin", pwd: "password", roles:[{role: "userAdminAnyDatabase" , db:"admin"}]})
Successfully added user: {
        "user" : "mongodadmin",
        "roles" : [
                {
                        "role" : "userAdminAnyDatabase",
                        "db" : "admin"
                }
        ]
}
>exit
Bye

Now login to MongoDB using admin credentials and configure the collection and drop collection

> mongo -u mongodadmin -p --authenticationDatabase admin
2020-12-09T15:57:11.007+0530 E QUERY    [thread1] SyntaxError: missing ; before statement @(shell):1:9

> show dbs
admin   0.000GB
config  0.000GB
local   0.000GB

Now create a collection by using the following command

> db.produxt.insert({item: "card", qty: 15})
WriteResult({ "nInserted" : 1 })

Now show the table by using the following command

> show collections
produxt
system.users
system.version

> db.product.insert({item: "card", qty: 15 })
WriteResult({ "nInserted" : 1 })

> show collections
product
produxt
system.users
system.version

Delete the existing table by using the following command

> db.produxt.drop()
true

> show collections
product
system.users
system.version

> exit
bye

With this method the installation and configuration of MongoDB on Linux Mint comes to an end.
