<\/a>1. Introduction<\/h2>\nMongoDB is one of the most popular open source NoSQL database solutions available. Unlike relational databases that store rows of data, document-oriented databases like this one store data as documents. These types of databases are not constricted by rigid schemas and scale much easier and efficiently than relational databases, meaning it is a lot easier to store an unthinkable amount of application data.<\/p>\n
MongoDB is able to achieve and maintain high performance \u2013 much greater than any relational database, such as Oracle or MySQL. This tutorial will help you to install MongoDB database on Ubuntu 16.04 LTS (Xenial), 14.04 LTS (Trusty) and 12.04 LTS (Precise Pangolin) systems.<\/p>\n
<\/a>1.1 Prerequisites<\/h3>\nFor this tutorial, we need:<\/p>\n
\n- Ubuntu Operating System 16.04 LTS (64-bit)<\/li>\n
- Root privileges<\/li>\n
- Significant amount of RAM<\/a><\/li>\n<\/ol>\n
<\/a>1.2 Download Ubuntu Operating System<\/h3>\nThe download is straight forward. Go to Ubuntu website and download<\/a> the .ISO image through the direct link. You can also check out the alternate download<\/a> link.<\/p>\n<\/a>1.3 Download & Install VMware Workstation<\/h3>\nYou can watch this<\/a> video in order to download and install VMware Workstation on Windows operating system.<\/p>\n<\/a>1.4 Install Ubuntu on VMware Workstation<\/h3>\nYou can watch this<\/a> video in order to install the Ubuntu 16.04 LTS Operating System on VMware workstation.<\/p>\n<\/a>2. Installation of MongoDB on Ubuntu<\/h2>\nBelow are steps which need to be executed on the Ubuntu operating system in order to successfully perform the MongoDB installation.<\/p>\n
<\/a>2.1 Adding MongoDB Repository<\/h3>\nMongoDB is generally included in the Ubuntu package repositories. However, a legitimate MongoDB repository affords the most up to date version change in an endorsed manner.<\/p>\n
To carry out this process, we first must import the key for the legitimate MongoDB repository using the following command:<\/p>\n
Import Public Key<\/em><\/span><\/p>\n$ sudo apt-key adv --keyserver hkp:\/\/keyserver.ubuntu.com:80 --recv 0C49F3730359A14518585931BC711F9BA15703C6<\/pre>\n![\"Fig.](\"http:\/\/examples.javacodegeeks.com\/wp-content\/uploads\/2017\/07\/mongodb-ubuntu-installation-guide-1.jpg\")
<\/a>Fig. 1: Add MongoDB Key<\/figcaption><\/figure><\/p>\nAfter that, we now have to add a file containing the MongoDB repository details under our \/etc\/apt\/sources.list.d\/<\/code> from which the MongoDB package files will be fetched.<\/p>\nNow run the following command as per your version of Ubuntu<\/strong>:<\/p>\nUbuntu 16.04<\/em><\/span><\/p>\n$ echo \"deb [ arch=amd64,arm64 ] http:\/\/repo.mongodb.org\/apt\/ubuntu xenial\/mongodb-org\/3.4 multiverse\" | sudo tee \/etc\/apt\/sources.list.d\/mongodb-org-3.4.list<\/pre>\nUbuntu 14.04<\/em><\/span><\/p>\n$ echo \"deb [ arch=amd64 ] http:\/\/repo.mongodb.org\/apt\/ubuntu trusty\/mongodb-org\/3.4 multiverse\" | sudo tee \/etc\/apt\/sources.list.d\/mongodb-org-3.4.list<\/pre>\nUbuntu 12.04<\/em><\/span><\/p>\n$ echo \"deb [ arch=amd64 ] http:\/\/repo.mongodb.org\/apt\/ubuntu precise\/mongodb-org\/3.4 multiverse\" | sudo tee \/etc\/apt\/sources.list.d\/mongodb-org-3.4.list<\/pre>\nNext, update the system package list as follows:<\/p>\n
Update System Package<\/em><\/span><\/p>\n$ sudo apt-get update<\/pre>\n<\/a>2.2 Installation of MongoDB Database<\/h3>\nAfter adding the required APT repositories, use the below command to install MongoDB on your systems. It will also install all dependent packages required for MongoDB.
<\/div> <\/div><\/p>\nInstall Stable MongoDB Package<\/em><\/span><\/p>\n$ sudo apt-get install -y mongodb<\/pre>\n![\"Fig.](\"http:\/\/examples.javacodegeeks.com\/wp-content\/uploads\/2017\/07\/mongodb-ubuntu-installation-guide-2.jpg\")
<\/a>Fig. 2: Install MongoDB in Ubuntu 16.04<\/figcaption><\/figure><\/p>\nNote<\/strong>: If you want to install any specific<\/strong> version of MongoDB<\/strong>, define the version number like:<\/p>\n$ apt-get install mongodb-org=3.4.1 mongodb-org-server=3.4.1 mongodb-org-shell=3.4.1 mongodb-org-mongos=3.4.1 mongodb-org-tools=3.4.10<\/pre>\nThe installation command installs mongodb-org<\/strong>, a meta-package<\/em> that includes the following:<\/p>\n\n- mongodb-org-server<\/strong>: The standard MongoDB daemon and relevant init scripts and configurations<\/li>\n
- mongodb-org-mongos<\/strong>: The MongoDB Shard daemon<\/li>\n
- mongodb-org-shell<\/strong>: The MongoDB shell, used to interact with MongoDB via the command line<\/li>\n
- mongodb-org-tools<\/strong>: Contains a few basic tools to restore, import, and export data, as well as a variety of other functions<\/li>\n<\/ol>\n
<\/a>2.3 Start and Stop MongoDB Service<\/h3>\nNow, that MongoDB has been successfully installed on your system, there are certain important things we are going to do in order to manage it under system<\/strong> unit.<\/p>\nThe first thing is to create a systemd unit<\/strong> file which defines a unit, in this case, our MongoDB service<\/em>. Systemd unit configuration files are stored in \/etc\/systemd\/system<\/code> directory and we shall create the mongodb.service<\/strong> file under it.<\/p>\nUse your editor of choice as follows:<\/p>\n
VI Editor<\/em><\/span><\/p>\n$ sudo vi \/etc\/systemd\/system\/mongodb.service\r\n<\/pre>\nThen add the following lines into that file:<\/p>\n
MongoDB Service Code<\/em><\/span><\/p>\n[Unit]\r\nDescription=High-performance, schema-free document-oriented database\r\nAfter=network.target\r\n[Service]\r\nUser=mongodb\r\nExecStart=\/usr\/bin\/mongod --quiet --config \/etc\/mongod.conf\r\n[Install]\r\nWantedBy=multi-user.target\r\n<\/pre>\n![\"Fig.](\"http:\/\/examples.javacodegeeks.com\/wp-content\/uploads\/2017\/07\/mongodb-ubuntu-installation-guide-3.jpg\")
<\/a>Fig. 3: Creating SystemD MongoDB Service<\/figcaption><\/figure><\/p>\nA quick explanation of the file sections:<\/p>\n
\n- Unit<\/strong>: Contains a human-readable description of the service and dependencies that need to be started for MongoDB service to work as required<\/li>\n
- Service<\/strong>: Specifies how the system should start a service depending on the directives provided. The User directive<\/strong> specifies user to run the MongoDB server and ExecStart directive<\/strong> specifies the command to start MongoDB service<\/li>\n
- Install<\/strong>: Directs systemd to start the service at boot time when required<\/li>\n<\/ol>\n
At this point, we can now start<\/em> our new service by running the command below:<\/p>\nStart MongoDB Service<\/em><\/span><\/p>\n$ sudo systemctl start mongodb<\/pre>\nTo check the status<\/em> of the service, issue the following command:<\/p>\nMongoDB Status<\/em><\/span><\/p>\n$ sudo systemctl status mongodb<\/pre>\n![\"Fig.](\"http:\/\/examples.javacodegeeks.com\/wp-content\/uploads\/2017\/07\/mongodb-ubuntu-installation-guide-4.jpg\")
<\/a>Fig. 4: Start and Verify MongoDB Service<\/figcaption><\/figure><\/p>\nTo stop<\/em> the MongoDB service, issue the following command:<\/p>\nStop MongoDB Service<\/em><\/span><\/p>\n$ sudo systemctl stop mongodb\r\n<\/pre>\nTip<\/strong>
\nTo make the MongoDB services start at boot time<\/strong>, use the following command: $ sudo systemctl enable mongodb<\/code><\/div>\nAll is now set for you to start using MongoDB for developing databases for your applications.<\/p>\n
<\/a>2.4 Verifying MongoDB Installation<\/h3>\nFinally, use the below command to check installed MongoDB version on your system:<\/p>\n
MongoDB Version<\/em><\/span><\/p>\n$ mongod -version<\/pre>\n![\"Fig.](\"http:\/\/examples.javacodegeeks.com\/wp-content\/uploads\/2017\/07\/mongodb-ubuntu-installation-guide-5.jpg\")
<\/a>Fig. 5: Validating MongoDB Version<\/figcaption><\/figure><\/p>\nAlso, connect MongoDB using the command line and execute some test commands for checking proper working.<\/p>\n

<\/a>3.1 Create MongoDB Admin User<\/h3>\nDevelopers can follow the below steps to create a user with admin privileges in the MongoDB server.<\/p>\n
Step 1<\/strong>: Before you set up a username and password for MongoDB, you need to open the MongoDB shell on your server. You can login by typing:<\/p>\nOpen MongoDB Shell<\/em><\/span><\/p>\n$ mongo<\/pre>\nStep 2<\/strong>: Once you are in the MongoDB shell, switch to the database named admin<\/em><\/p>\nSwitch to the Database Admin<\/em><\/span><\/p>\n> use admin;<\/pre>\nStep 3<\/strong>: Create the Root User<\/p>\nRoot User<\/em><\/span><\/p>\n> db.createUser({user:\"myadmin\", pwd:\"admin123\", roles:[{role:\"userAdminAnyDatabase\",db:\"admin\"}]});<\/pre>\nThe output will display all the information written to the database except the password.<\/p>\n

<\/a>Fig. 8: MongoDB User Authentication<\/figcaption><\/figure><\/p>\nTip<\/strong>
\nThe -u<\/strong>, -p<\/strong>, and –authenticationDatabase<\/strong> options in the above command are required in order to authenticate connections to the shell.<\/div>\n<\/a>3.2 Add User for Database<\/h3>\nDevelopers can also create database specific users, i.e. the user will have access to that database only. They can also specify the access level for that user on the database.<\/p>\n
For example, we are creating a user account with read-write access on mydb<\/code> database:<\/p>\nStep 1<\/strong>: Create Specific User<\/p>\nSpecific User<\/em><\/span><\/p>\n> db.createUser({user: \"jcg\", pwd: \"jcg123\", roles: [{role:\"readWrite\", db: \"mydb\"}]});<\/pre>\nAnd you will see the output like this:<\/p>\n

<\/a>2.4 Verifying MongoDB Installation<\/h3>\n
Finally, use the below command to check installed MongoDB version on your system:<\/p>\n
MongoDB Version<\/em><\/span><\/p>\n
$ mongod -version<\/pre>\n
<\/a>Fig. 5: Validating MongoDB Version<\/figcaption><\/figure><\/p>\n Also, connect MongoDB using the command line and execute some test commands for checking proper working.<\/p>\n
<\/a>Fig. 6: MongoDB Implementation<\/figcaption><\/figure><\/p>\n <\/a>3. Creating MongoDB User Accounts<\/h2>\n
The default installation provides you the access to the database using mongo command through command line without authentication.<\/p>\n
<\/a>3.1 Create MongoDB Admin User<\/h3>\n
Developers can follow the below steps to create a user with admin privileges in the MongoDB server.<\/p>\n
Step 1<\/strong>: Before you set up a username and password for MongoDB, you need to open the MongoDB shell on your server. You can login by typing:<\/p>\n
Open MongoDB Shell<\/em><\/span><\/p>\n
$ mongo<\/pre>\n
Step 2<\/strong>: Once you are in the MongoDB shell, switch to the database named admin<\/em><\/p>\n
Switch to the Database Admin<\/em><\/span><\/p>\n
> use admin;<\/pre>\n
Step 3<\/strong>: Create the Root User<\/p>\n
Root User<\/em><\/span><\/p>\n
> db.createUser({user:\"myadmin\", pwd:\"admin123\", roles:[{role:\"userAdminAnyDatabase\",db:\"admin\"}]});<\/pre>\nThe output will display all the information written to the database except the password.<\/p>\n

Step 5<\/strong>: Restart MongoDB service and try to connect.<\/p>\n
Now, restart the MongoDB service.<\/p>\n
Restart MongoDB Service<\/em><\/span><\/p>\n
$ sudo systemctl restart mongodb<\/pre>\n
And test your connection to MongoDB instance with the credentials created in Step 3, using the admin database for authentication:<\/p>\n
My Admin Credentials<\/em><\/span><\/p>\n
$ mongo -u myadmin -p --authenticationDatabase admin<\/pre>\n
And you will see the output like this:<\/p>\n
<\/a>Fig. 8: MongoDB User Authentication<\/figcaption><\/figure><\/p>\n Tip<\/strong>
\nThe -u<\/strong>, -p<\/strong>, and –authenticationDatabase<\/strong> options in the above command are required in order to authenticate connections to the shell.<\/div>\n<\/a>3.2 Add User for Database<\/h3>\n
Developers can also create database specific users, i.e. the user will have access to that database only. They can also specify the access level for that user on the database.<\/p>\n
For example, we are creating a user account with read-write access on
mydb<\/code> database:<\/p>\nStep 1<\/strong>: Create Specific User<\/p>\n
Specific User<\/em><\/span><\/p>\n
> db.createUser({user: \"jcg\", pwd: \"jcg123\", roles: [{role:\"readWrite\", db: \"mydb\"}]});<\/pre>\nAnd you will see the output like this:<\/p>\n
- Service<\/strong>: Specifies how the system should start a service depending on the directives provided. The User directive<\/strong> specifies user to run the MongoDB server and ExecStart directive<\/strong> specifies the command to start MongoDB service<\/li>\n
