HOW TO INSTALL MONGODB COMMUNITY EDITION ON LINUX UBUNTU?

How to install mongodb in linux ubuntuAs of version 3.0, MongoDB can be installed more easily on Linux
Ubuntu or Elementary OS.
In this article we will see how to install MongoDB for Ubuntu 12.04 LTS (Precise Pangolin) and Ubuntu 14.04.5 LTS (Trusty Tahr).

It is very likely that this type of installation also works correctly for new versions of Ubuntu.

IMPORTING THE PUBLIC KEY USED BY THE UBUNTU PACKAGE MANAGER SYSTEM

Ubuntu’s package management tools (ie dpkg and apt) ensure consistency and
authenticity of the package by requiring distributors to sign packages with GPG keys.
Run the following command to import the MongoDB GPG public key:

sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv EA312927

CREATING A LIST TYPE FILE FOR MONGODB

In this file you will find the list of repositories from which mongoDB will be installed.

IF I AM USING ELEMENTARY OS, HOW DO I KNOW WHICH VERSION OF UBUNTU I AM USING?

Simply by executing the following command:

lsb_release -a -u | grep "Description"

This command will give us a result similar to the following:

Description:	Ubuntu 14.04.5 LTS

We create the file type list /etc/apt/sources.list.d/mongodb-org-3.2.list, using the
appropriate command for the version of ubuntu that you are using:

UBUNTU 12.04

echo "deb http://repo.mongodb.org/apt/ubuntu precise/mongodb-org/3.2 multiverse" | sudo tee /etc/apt/sources.list.d/mongodb-org-3.2.list

UBUNTU 14.04.5

echo "deb http://repo.mongodb.org/apt/ubuntu trusty/mongodb-org/3.2 multiverse" | sudo tee /etc/apt/sources.list.d/mongodb-org-3.2.list"

WE UPDATE THE LOCAL PACKAGE DATABASE OF OUR SO

sudo apt-get update

INSTALLING MONGODB PACKAGES

We can install the latest stable version of MongoDB or a specific version of MongoDB.

INSTALLING THE LATEST STABLE VERSION OF MONGODB

sudo apt-get install -y mongodb-org

INSTALLING A SPECIFIC VERSION OF MONGODB

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

sudo apt-get install -y mongodb-org=3.2.5 mongodb-org-server=3.2.5 mongodb-org-shell=3.2.5
mongodb-org-mongos=3.2.5 mongodb-org-tools=3.2.5

If only mongodb-org = 3.2.5 is installed, and the other components are not included, the
latest version of each MongoDB component will be installed, regardless of the version you specified.

VERIFYING MONGODB INSTALLATION

To verify if the installation of MongoDB has been successful simply write in the terminal the
following command:

mongo --version

If it indicates a version number, for example MongoDB shell version: 3.2.5, it means that MongoDB version 3.2.5 has been correctly installed.

RUNNING / RUNNING MONGODB

The MongoDB instance stores its data files in / var / lib / mongodb and its log record in / var / log / mongodb by default, and runs using the mongodb user account. You can specify
alternate logfile and logfile directories in /etc/mongod.conf.

STARTING MONGODB

We execute the following command to start MongoDB:

sudo service mongod start

VERIFYING THAT MONGODB HAS STARTED CORRECTLY

Verify that the mongod process has started successfully by checking the contents of the log file in /var/log/mongodb/mongod.log with the following command:

cat /var/log/mongodb/mongod.log

When executing this command we will be able to see the current log of MongoDB.

STOPPING THE MONGODB SERVICE

To stop the MongoDB service we simply have to type the following command:

sudo service mongod stop

RESTARTING THE MONGODB SERVICE

To restart the MongoDB service we simply have to type the following command:

sudo service mongod restart

Well friends, I hope this article is useful to you, if you find a bug please do not
