MongoDB is a Free and open-source cross-platform document-oriented database program. Classified as a NoSQL database program, MongoDB avoids the traditional table-based relational database structure in favor of JSON-like documents with dynamic schemas, making the integration of data in certain types of applications easier and faster.

1. Login into your VPS via ssh
   
   
2. Create mongodb repository file using an editor as below.
   
   nano /etc/yum.repos.d/mongodb.repo
   
   
   
   
3. If you are running a 64-bit system, add the below information to the file you have created.
   
   [mongodb]
   
   name=MongoDB Repository
   
   baseurl=http://downloads-distro.mongodb.org/repo/redhat/os/x86_64/
   
   gpgcheck=0
   
   enabled=1
   
   
   
   
4. Press CTRL+x to exit and press Y to save the file as per screenshot.
   
   
   
   
5. It will ask to confirm filename and path. Just press enter.
   
   
   
   
6. As a best practice, we should also update our package using below command.
   
   yum -y update
   
   
7. Now, run below command to install MongoDB.
   
   yum -y install mongodb-org mongodb-org-server
   
   

That's it. MongoDB is installed. Below are some useful commands.

• Start-Up MongoDB - systemctl start mongod
  
  
• Check MongoDB Service Status - systemctl status mongod
  
  
• Enter the MongoDB Command Line - mongo
  
  
• Shutdown MongoDB - systemctl stop mongod
  
  
• Summary List of Status Statistics (Continuous) - mongostat
  
  
• Summary List of Status Statistics (5 Rows, Summarized Every 2 Seconds) - mongostat --rowcount 5 2
  
  
• By default MongoDB server listening on port 27017 on the localhost interface.To change mongodb listening port to 22222 :: mongo --port 22222
