This post is basic installation process step by step for installing MongoDB on Ubuntu 13.04 follows the tutorial from MongoDB official document. We will use .deb packages from MongoDB official pakages as the basis of the installation.

Step 1: Import MongoDB public GPG key

The Ubuntu package management tool (i.e. dpkg and apt) ensure package consistency and authenticity by requiring that distributors sign packages with GPG keys
sudo apt-key adv --keyserver hkp:// --recv 7F0CEB10

Step 2: Create mongodb source list file

echo 'deb dist 10gen' | sudo tee /etc/apt/sources.list.d/mongodb.list

Step3: Reload your repository 

sudo apt-get update

Step 4: Install mongodb packages

sudo apt-get install mongodb-10gen

For lastest version of MongoDB 

During installing MongoDB, you can see that it creates new account named mongodb and mongodb group in the system to use  mongoDB instance.  So If you change the user that runs the MongoDB process, you will need to modify the access control rights to the /var/lib/mongodband /var/log/mongodb directories.

Step 5: Test new MongoDb 

- Let's try  to Start, Stop and Restart MongoDB 

- You can see in the image above, after installation process is finished, it's start mongoDb automatically.  If not, you should use the command : sudo service mongodb start  to start it up.
We also have the command: sudo service mongodb stop  and sudo service mongodb restart  to stop and start it.

 Testing mogodb on mongo shell 

  - To ensure mongodb works well, try some basic command to save new data and find them on mongo shell.
 - To use mongodb on mongo shell, just type : mongo on terminal.
    + To add new data  into mongodb try : ({codingtip : 1})
    + To see all data in database , try : db.test.find() 
with db.test is Test database which is auto created by mongodb in installations
