File System (Optional)
You can either use XFS or EXT4 type filesystem to hold the MongoDB database (/var/lib/mongodb). If possible, use the XFS filesystem for better performance.
Security Checklist
Admin User
By default, MongoDB doesn’t authenticate users to read and modify data. So, create an admin user for daily operation.
Access Control
Noe, enable access control to enforce authentication to allow only identified users to perform actions based on their roles.
sudo nano /etc/mongod.conf
Add the below lines.
security: authorization: enabled
Start Service

Start MongoDB server, run:
sudo systemctl start mongod
Enable MongoDB service to start automatically at the system startup, run:
sudo systemctl enable mongod
Check the status of MongoDB service, run.
sudo systemctl status mongod
