How to start mongodb in ubuntu?

To start MongoDB on Ubuntu, you can follow these steps:

1. Open a terminal window and type the following command to check if MongoDB is already installed:

1

$ which mongod

If the command returns a path, then MongoDB is already installed on your system. If it returns "mongod: not found", then you need to install MongoDB.

1. If you need to install MongoDB, you can follow these steps:

• Add the MongoDB repository to your system by running the following command:

1

$ sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv 9DA31620334BD75D9DCB49F368818C72E52529D4

• Add the MongoDB repository to your list of repositories by running the following command:

1

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

• Update the package list by running the following command:

1

$ sudo apt-get update

• Install the latest version of MongoDB by running the following command:

1

$ sudo apt-get install -y mongodb-org

1. Once MongoDB is installed, you can start the MongoDB daemon by running the following command:

1

$ sudo service mongod start

This will start the MongoDB daemon and run it in the background. You can check the status of the daemon by running the following command:

1

$ sudo service mongod status

If the daemon is running, you should see a message indicating that the daemon is active. If it is not running, you can try starting it again or check the logs for any error messages.

1. To stop the MongoDB daemon, you can use the following command:

1

$ sudo service mongod stop

This will stop the MongoDB daemon and close all open connections.

I hope this helps! Let me know if you have any questions.
