{% embed url="<https://youtu.be/kFphd4pD7Cs>" %}

### Overview

MongoDB is a widely used open-source NoSQL database management system. It is highly scalable and provides high performance for large data sets. In this guide, we will walk you through the step-by-step process of installing MongoDB on a CentOS 7 server.&#x20;

### **Prerequisites**

There are certain prerequisites that need to be met before you begin:&#x20;

1. Server running CentOS 6 / CentOS 7 / CentOS 8&#x20;
2. Access to SSH connected text editor&#x20;
3. User account with root or sudo access&#x20;
4. Internet connection&#x20;

**Step 1: Enter as Root User**&#x20;

For making changes in the configuration file, you need to enter as a root user, with the following command:&#x20;

```
sudo -i 
```

**Step 2: Setting up Environment for MongoDB**&#x20;

* The MongoDB repository is not included in the default CentOS 7 package repositories. Therefore, you need to add it manually. Create a MongoDB repository file under the /etc/yum.repos.d/ directory using the following command:&#x20;

```
nano /etc/yum.repos.d/mongodb-org-4.4.repo 
```

**Note:** If you get the error **nano:** **command not found,** enter as root user and then install the nano text editor, using the following command:&#x20;
{% endhint %}

```
sudo -i 
```

```
yum install nano 
```

&#x20;

When asked **Is this Ok**, enter **y** to continue the installation.&#x20;

* Add the following lines in the mongodb-org-4.4.repo configuration file:&#x20;

```
[mongodb-org-4.4]  

name=MongoDB Repository  

baseurl=https://repo.mongodb.org/yum/redhat/$releasever/mongodb-org/4.4/x86_64/  

gpgcheck=1  

enabled=1  

gpgkey=https://www.mongodb.org/static/pgp/server-4.4.asc  
```

&#x20;

Once, you have added the lines in the configuration file, save and close it using the commands Ctrl + O, press enter and then enter Ctrl +X.&#x20;

* Now that the MongoDB repository is added, use the following command to install the latest stable version of MongoDB:&#x20;

```
sudo yum install -y mongodb-org 
```

Executing this command will install the MongoDB package as well as all the necessary dependencies required for its proper functioning.&#x20;

By now, you should have successfully installed MongoDB on your system.&#x20;

**Step 4: Start MongoDB Service**&#x20;

After the installation is complete, start the MongoDB service using the following command:&#x20;

```
systemctl start mongod.service 
```

To ensure that MongoDB starts automatically at system boot, run the following command:&#x20;

```
sudo systemctl enable mongod.service 
```

**Step 5: Verify MongoDB Installation**&#x20;

To verify the installation, use the following command to check the MongoDB service status:&#x20;

```
sudo systemctl status mongodb  
```

**Step 6: Connect to MongoDB**&#x20;

You can connect to the MongoDB server using the **mongo** shell command:&#x20;

```
mongo 
```

&#x20;\
This will open the MongoDB shell. You can now start using MongoDB.&#x20;
