MongoDB Installation – Ubuntu

MongoDB is one of the document oriented open source database developed in c++, first come into shape in 2007 when in order to overcome the shortfall of existing database while working for an advertising company “DoubleClick” development team has decided to go further rather than struggling with database.  The team of this advertising company was frustrated with their existing DB as the team was struggling for scalability and agility both on their existing DB.  While facing such issues Dwight Merriman, Eliot Horowitz and Kevin Ryan has got an idea and they took this up further to develop MongoDB.

They have founded MongoDB Inc.

Like any other DB MongoDB also supports multi platform.  MongoDB Inc. has released many binaries of every version which runs on different platform like OSx, Windows and different flavour of Unix like RedHat, SUSE, Amazon Linux etc.  Besides these there are enterprise edition releases as well which also supports on various platform.

Installation of MongoDB, like its operations,  is very simple and straight forward.  We will take a look here for installation of MongoDB on Ubuntu.

Very first step to install any version of MongoDB on any unix platform is to Import the public key used by the package management system.  By importing this public key, Ubuntu package management tools is able to ensure authenticity by requiring that distributors sign packages with GPG keys.  Since, the packages are signed by GPG keys, Ubuntu can believe on integrity of these packages as well.

sanjeeva@mishika:~$ sudo apt-key adv –keyserver hkp://keyserver.ubuntu.com:80 –recv 7F0CEB10
[sudo] password for sanjeeva:

gpg: key 7F0CEB10: public key “Richard Kreuter <richard@10gen.com>” imported
gpg: Total number processed: 1
gpg: imported: 1 (RSA: 1)

Once public key are imported into the system, we have to create the list of files for MongoDB.  This will be created into “sources.list.d” folder in apt of etc.
sanjeeva@mishika:~$  echo “deb http://repo.mongodb.org/apt/ubuntu trusty/mongodb-org/3.0 multiverse” | sudo tee /etc/apt/sources.list.d/mongodb-org-3.0.listdeb http://repo.mongodb.org/apt/ubuntu trusty/mongodb-org/3.0 multiverse
sanjeeva@mishika:~$

After creating list of files for MongoDB, we have to reload the local package database.  To achieve this we have to execute update on package management tool.
sanjeeva@mishika:~$   sudo apt-get update

Now system is ready for installation of MongoDB.  By default it will install the latest stable version but we can control this behavior and can install any specific version of database.  In case if we want to install any specific version then we have to supply the version of all packages which MongoDB is going to install.

In all cases database is going to install five packages which is required in order to run MongoDB. Details of these packages are

  • mongodb-org-server:  This package contains the mongod daemon and associated configuration and init scripts.
  • mongodb-org-mongos: This package contains the mongos daemon.
  • mongodb-org-shell: This package contains the mongo shell.
  • mongodb-org: This package is a metapackage that will automatically install the four component packages listed below.
  • mongodb-org-tools: This package contains the following MongoDB tools: mongoimport bsondump, mongodump, mongoexport, mongofiles, mongooplog, mongoperf, mongorestore, mongostat, and mongotop.

To Install MongoDB by Default we have to execute “sudo apt-get” package management tool on Ubuntu.

sanjeeva@mishika:~$ sudo apt-get install -y mongodb-org

 To start database using services you need to create a service daemon manually.  To do this create a file “mongod.service”.  Use content mentioned here for this file to work properly.

sanjeeva@mishika:~$ sudo vi /lib/systemd/system/mongodb.service
[Unit]
Description=High-performance, schema-free document-oriented database
After=network.target

[Service]
User=mongodb
ExecStart=/usr/bin/mongod –quiet –config /etc/mongod.conf

[Install]
WantedBy=multi-user.target

After the creation of this file you can start database.


sanjeeva@mishika:/etc/apt/sources.list.d$  systemctl daemon-reload

sanjeeva@mishika:/etc/apt/sources.list.d$

sanjeeva@mishika:/etc/apt/sources.list.d$  service mongod start

You can check the log file

sanjeeva@mishika:~$ tail -f /var/log/mongodb/mongod.log
