# How To Install MongoDB on Ubuntu 22.04 MongoDB is an open-source NoSQL database that uses a flexible, document-oriented data model. Unlike traditional relational databases that use tables and rows, MongoDB stores data in JSON-like documents with varied structures. This makes it highly adaptable and suitable for applications requiring scalable, high-performance, and flexible data storage solutions. {% embed url="\_" %} ## Prerequisites * Launch the [Ubuntu 22.04 instance](https://docs.neevcloud.com/neevcloud-products/computes/getting-started-launch-vms) on Neevcloud * Access the server using [SSH](https://docs.neevcloud.com/neevcloud-products/computes/getting-started-launch-vms#ssh) ### Update && Upgrade the system First, ensure your package list is up to date to avoid any issues with outdated packages ``` sudo apt-get update -y sudo apt-get upgrade -y ```

## Installation MongoDB Execute the given command to install the MongoDB package. ``` sudo apt install software-properties-common gnupg apt-transport-https ca-certificates -y ```

### Add necessary packages To install the most recent MongoDB package, you need to add the MongoDB package repository to your sources list file on Ubuntu. ``` curl -fsSL https://pgp.mongodb.com/server-7.0.asc | sudo gpg -o /usr/share/keyrings/mongodb-server-7.0.gpg --dearmor ``` After this next. add MongoDB APT repository to the **`/etc/apt/sources.list.d/`** directory. ``` echo "deb [ arch=amd64,arm64 signed-by=/usr/share/keyrings/mongodb-server-7.0.gpg ] https://repo.mongodb.org/apt/ubuntu jammy/mongodb-org/7.0 multiverse" | sudo tee /etc/apt/sources.list.d/mongodb-org-7.0.list ``` Next, include the MongoDB source list file in the `/etc/apt/sources.list.d/` directory, which consists of a lone line stating ``` echo "deb [ arch=amd64,arm64 signed-by=/usr/share/keyrings/mongodb-server-7.0.gpg ] https://repo.mongodb.org/apt/ubuntu jammy/mongodb-org/7.0 multiverse" ```

* Add all repositories first, then update the packages ``` sudo apt update ``` **Now, proceed to install the mongodb-org meta-package, which includes MongoDB.** ``` sudo apt install mongodb-org -y ```

### Verify the version of MongoDB Installed ``` sudo mongod --version ```

### Start and Enable MongoDB * After installation, the MongoDB service starts and enables ``` sudo systemctl start mongod ``` * Enable it to start when the system rebooted ``` sudo systemctl enable mongod ``` ### Manage MongoDB Service To verify the database's status, make sure the server is actively listening on port 27017. ``` ss -antpl | grep 27017 ```

### To check the status Verify that the database service is active and running. Run the following command ``` sudo systemctl status mongod ```

## Create MongoDB databases and User Make sure the MongoDB instance is up and set up for remote access, then learn how to create a database and a user in MongoDB. ### To access the MongoDB, run the following command. ``` sudo mongosh ```

{% hint style="info" %} By default, installation results in the creation of three databases. This includes admin, config, and local. {% endhint %} ### To list the existing databases, run these commands. ``` show dbs ```

To make a database, execute the **`use`** command with the name of the database. For example, to create a database named **`test_db`**, run the command ``` use test_db ``` To verify the database you are using, execute the **`db`** command. In this scenario, the output will be **`test_db`**.

### To create a User MongoDB offers various shell techniques to control your database. The `db.createUser` function enables the creation of a new user within a database. This is how you can create a user name **`test_user`** with read-and-write roles for the **`test_db`** database. {% hint style="info" %} ```bash db.createUser( { user: "test_user", pwd: "test-password", roles: [ { role: "readWrite", db: "test_db" } ] } ) ``` {% endhint %}

You can list the users created using the `db.getUsers()` command. ``` db.getUsers(); ```

Alternatively, run the command ``` show users ```
