How to Install MongoDB on Ubuntu 16.04

---

MongoDB is a cross-platform, document oriented database that provides, high performance, high availability, and easy scalability. MongoDB works on concept of collection and document. The official Ubuntu 16.04 MongoDB packages have not yet been published by the MongoDB maintainers. This article explains about “How to install Mongo DB on Ubuntu and start the MongoDB service on  boot”

Adding the MongoDB Repository

MongoDB is generally included in a Ubuntu package repositories. However, a legitimate MongoDB repository affords the most upto date version change in an endorsed manner.

To carry out this process, we first must import the key for the legitimate MongoDB repository using the following command-

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

The sample output should be like this –

Executing: /tmp/tmp.Qe1RFZgUh2/gpg.1.sh --keyserver
hkp://keyserver.ubuntu.com:80
--recv
EA312927
gpg: requesting key EA312927 from hkp server keyserver.ubuntu.com
gpg: key EA312927: public key "MongoDB 3.2 Release Signing Key <packaging@mongodb.com>" imported
gpg: Total number processed: 1
gpg:               imported: 1  (RSA: 1)

To add the MongoDB repository, use the following command-

$ sudo echo "deb http://bit.ly/1rU162C trusty/mongodb-org/3.2 multiverse" | sudo tee /etc/apt/sources.list.d/mongodb-org-3.2.list

Now, we need to update the package list using the following command –

$ sudo apt-get update

Installing and Verifying MongoDB

To install the MongoDB, use the following command –

$ sudo apt-get install -y --allow-unauthenticated mongodb-org

The sample output should be like this –

Reading package lists... Done
Building dependency tree       
Reading state information... Done
The following packages were automatically installed and are no longer required:
  apport-hooks-elementary contractor javascript-common libgda-5.0-4
  libgda-5.0-common libgranite-common libgranite3 libgsignon-glib1
  libindicate5 libjs-jquery libnoise-core0 libtagc0
Use 'sudo apt autoremove' to remove them.
The following additional packages will be installed:
  mongodb-org-mongos mongodb-org-server mongodb-org-shell mongodb-org-tools
The following NEW packages will be installed:
  mongodb-org mongodb-org-mongos mongodb-org-server mongodb-org-shell
  mongodb-org-tools

In order to properly launch MongoDB as a service on Ubuntu 16.04, we additionally need to create a unit file describing the service. A unit file tells the system – a way to manage a resource. The most common unit type is a service, which determines how to start or stop the service.

Create a configuration file named mongodb.service to setup unit file as shown below –

$ sudo nano /etc/systemd/system/mongodb.service

Paste the following code –

[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

Now start the newly created service with systemctl as shown below –

$ sudo systemctl start mongodb

It generally doesn’t return any output.  Now, we need to check, if the service has started properly. In order to execute this process, use the following command –

$ sudo systemctl status mongodb

The sample output should be like this –

mongodb.service - High-performance, schema-free document-oriented database
   Loaded: loaded (/etc/systemd/system/mongodb.service; disabled; vendor preset:
   Active: active (running) since Fri 2016-05-13 10:33:52 IST; 1min 48s ago
 Main PID: 7078 (mongod)
    Tasks: 16 (limit: 512)
   CGroup: /system.slice/mongodb.service
           └─7078 /usr/bin/mongod --quiet --config /etc/mongod.conf

May 13 10:33:52 linux systemd[1]: Started High-performance, schema-free document
lines 1-9/9 (END)

To enable the process of automatically starting MongoDB, when the system starts, use the following command –

$ sudo systemctl enable mongodb

The sample output should be like this –

Created symlink from /etc/systemd/system/multi-user.target.wants/mongodb.service to /etc/systemd/system/mongodb.service.
