How do I install MongoDB on Ubuntu 20.04 terminal?
Although your primary focus is on uninstalling apps, I’ll provide you with a guide on how to install MongoDB on Ubuntu 20.04 Terminal. This can help you understand the installation process before discussing the uninstallation steps.
1. First, update the system package list by running the following command in your terminal:
“`bash
sudo apt update
“`
2. Now, import the MongoDB GPG key using the following command:
“`bash
wget -qO – https://www.mongodb.org/static/pgp/server-4.4.asc | sudo apt-key add –
“`
3. After importing the key, create a new file named “/etc/apt/sources.list.d/mongodb-org-4.4.list” and add the MongoDB repository details in it using the below command:
“`bash
echo “deb [ arch=amd64,arm64 ] https://repo.mongodb.org/apt/ubuntu focal/mongodb-org/4.4 multiverse” | sudo tee /etc/apt/sources.list.d/mongodb-org-4.4.list
“`
4. Update the package list again to include the newly added MongoDB repository:
“`bash
sudo apt update
“`
5. Install MongoDB by executing this command:
“`bash
sudo apt-get install -y mongodb-org
“`
6. Once installed, start the MongoDB service and enable it to run at startup using these commands:
“`bash
sudo systemctl start mongod
sudo systemctl enable mongod
“`
Now, MongoDB is installed on your Ubuntu 20.04 System. If at any point you wish to uninstall MongoDB, follow these steps:
1. Stop the MongoDB service:
“`bash
sudo systemctl stop mongod
“`
2. Remove MongoDB packages and associated data:
“`bash
sudo apt-get purge mongodb-org*
“`
3. Optionally, remove the MongoDB repository details from the “/etc/apt/sources.list.d/mongodb-org-4.4.list” file:
“`bash
sudo rm /etc/apt/sources.list.d/mongodb-org-4.4.list
“`
4. Update the package list to reflect the changes:
“`bash
sudo apt update
“`
5. If you want to remove any additional data created by MongoDB, delete the data directory (by default, it is “/var/lib/mongodb”):
“`bash
sudo rm -r /var/lib/mongodb
“`
With these steps, you have successfully uninstalled MongoDB from your Ubuntu 20.04 System.
How do I know if MongoDB is installed on Ubuntu?
To check if MongoDB is installed on your Ubuntu system, you can follow these simple steps:
1. Open the Terminal by pressing Ctrl+Alt+T or searching for “Terminal” in the application menu.
2. Type the following command to check if the MongoDB service is installed and running:
“`
sudo systemctl status mongodb
“`
If MongoDB is installed and running, the output will show that the MongoDB service is active. Otherwise, you will see a message stating that the service could not be found.
3. Alternatively, you can also use the following command to check for the installed MongoDB version:
“`
