Mongodb install & uninstall

  Image result for mongodb
MongoDB is an open-source document database and leading NoSQL database. MongoDB is written in C++. This tutorial will give you great understanding on MongoDB concepts needed to create and deploy a highly scalable and performance-oriented database.

Explanation: 
This operation executes the index.js script in a mongo shell that connects to the mydb database on the mongod instance accessible via the localhost interface on port 27017. localhost:27017 is not mandatory as this is the default port mongodb uses. Also, you can run a .js file from within mongo console.
 >load("index.js")

install the mongo db in Terminal(ubundu 16.04)

Step 1: Import the public key used by the package management system. 


sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv 2930ADAE8CAF5059EE73BB4B58712A2291FA4AD5

Step 3: Reload local package database.
sudo apt-get update

Step 4: Install the MongoDB packages.

sudo apt-get install -y mongodb-org



Install a specific release of MongoDB.

To install a specific release, you must specify each component package individually along with the version number, as in the following example:

sudo apt-get install -y mongodb-org=3.6.0 mongodb-org-server=3.6.0 mongodb-org-shell=3.6.0 mongodb-org-mongos=3.6.0 mongodb-org-tools=3.6.0

If you only install mongodb-org=3.6.0 and do not include the component packages, the latest version of each MongoDB package will be installed regardless of what version you specified.



Run MongoDB Community Edition

Step 2: Verify that MongoDB has started successfully    
Verify that the mongod process has started successfully by checking the contents of the log file at/var/log/mongodb/mongod.log for a line reading

<port> : 27017
Step 3: Stop MongoDB.sudo service mongod stop
Step 4: Restart MongoDB.
