How to Install MongoDB on Ubuntu 14.04 LTS

          MongoDB is a NoSQL database intended for storing large amounts of data in document-oriented storage with dynamic schemas. NoSQL refers to a database with a data model other than the tabular format used in relational databases such as MySQL, PostgreSQL, and Microsoft SQL. MongoDB features include: full index support, replication, high availability, and auto-sharding.

Pre-Flight Check

• These instructions are intended for installing MongoDB on a single Ubuntu 14.04 LTS node.
• I’ll be working from a Liquid Web Core Managed Ubuntu 14.04 LTS server, and I’ll be logged in as a non-root user, but with sudo access. For information on giving a user sudo access visit our page onHow to Add a User and Grant Root Privileges on Ubuntu 14.04.

Step #1: Setup a the Package Database

First we’ll import the MongoDB public key used by the package management system:

sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv 7F0CEB10

Then we’ll create a list file for MongoDB:

echo 'deb http://downloads-distro.mongodb.org/repo/ubuntu-upstart dist 10gen' | sudo tee /etc/apt/sources.list.d/mongodb.list

Now reload the package database:

sudo apt-get update

Step #2: Install Latest Stable Version MongoDB

At this point, installing MongoDB is as simple as running just one command:

sudo apt-get install -y mongodb-org

If you’d like MongoDB to auto-update with apt-get than you’re done with the installation. But, it’s possible to ‘pin’ the version of MongoDB you just installed to prevent apt-get from auto-updating.

echo "mongodb-org hold" | sudo dpkg --set-selections
echo "mongodb-org-server hold" | sudo dpkg --set-selections
echo "mongodb-org-shell hold" | sudo dpkg --set-selections
echo "mongodb-org-mongos hold" | sudo dpkg --set-selections
echo "mongodb-org-tools hold" | sudo dpkg --set-selections

Step #3: Get MongoDB Running

Start-Up MongoDB

sudo service mongod start

Check MongoDB Service Status

sudo service mongod status

Summary List of Status Statistics (Continuous)

mongostat

Summary List of Status Statistics (5 Rows, Summarized Every 2 Seconds)

mongostat --rowcount 5 2

Enter the MongoDB Command Line

mongo

By default, running this command will look for a MongoDB server listening on port 27017 on the localhost interface.

If you’d like to connect to a MongoDB server running on a different port, then use the –port option. For example, if you wanted to connect to a local MongoDB server listening on port 22222, then you’d issue the following command:

mongo --port 22222

Shutdown MongoDB

sudo service mongod stop

Restart MongoDB

sudo service mongod restart
