MongoDB on Linux distribution ( Ubuntu 20.04 LTS )
In this article guide, I will show you how to install, run, and uninstall MongoDB on ubuntu 20.04.
MongoDB is one of the most popular NoSQL databases. MongoDB is used to store and work on data without the use of schema or
ordering patterns. The MongoDB NoSQL database is widely used in web
applications because it has easier integration with various programming
languages.
Install MongoDB NoSQL Database:
MongoDB is very easy to install, and it is present in Ubuntu 20.04 software repository.
Step 1:
As always, first, update and upgrade your APT.
Terminal :
$ sudo apt update
$ sudo apt upgrade
Step 2:
Now download and install it
via the following terminal command. It requires root privileges so
type sudo with command.
Terminal :
$ sudo apt install mongodb
Step 3:
MongoDB is installed on your system now and it starts automatically after installation. To check the status of this database, type the following command in the terminal window.
Terminal :
$ sudo systemctl status mongodb
Run MongoDB service:
MongoDB service needs the
systemctl command to modify its state. It requires root privileges so
sudo must be used before every command.
MongoDB status checking:
The following command is used to check the status.
Terminal :
$ sudo systemctl status mongodb
MongoDB starts command:
MongoDB can be started through the following command.
Terminal :
$ sudo systemctl start
mongodb
MongoDB stop command:
MongoDB can be stopped with this command.
Terminal :
$ sudo systemctl stop
mongodb
MongoDB restart command:
In case you run into some errors and restart is compulsory then type the following command.
Terminal :
$ sudo systemctl restart mongodb
Enable option MongoDB when the system boots:
Terminal :
$ sudo systemctl enable
mongodb
Disable option for MongoDB when the system boots:
Terminal :
$ sudo systemctl disable
mongodb
By default, MongoDB is enabled after installation.
Starting MongoDB shell:
To work on the databases, you can open the “mongo shell” with the following terminal command.
Terminal :
$ sudo mongo
Uninstall MongoDB:
In case you do not need MongoDB and want to uninstall it then enter these three commands.
Terminal :
$ sudo systemctl stop
mongodb
This command will stop the
service.
Terminal :
$ sudo apt purge mongodb
$ sudo apt autoremove
These two commands will uninstall the MongoDB database. This will wipe out all the database files so make sure that you have backed up your necessary files.
