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 the concepts of collections and documents. MongoDB maintainers have not yet released official Ubuntu 16.04 MongoDB packages. This article explains "How to install Mongo DB on Ubuntu and start the MongoDB service at boot"

Add MongoDB repository

MongoDB is usually included in the Ubuntu package repository. However, legitimate MongoDB repositories provide the latest version changes in an approved manner.

To perform this process we first have to import the keys for a legitimate MongoDB repository using the following command -

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

The example output should look 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 MongoDB repository, use the following command -

$ sudo 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

Now we need to update the package list using the following command -

$ sudo apt-get update

Install and verify MongoDB

To install MongoDB, use The following command –

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

The sample output should look like this –

In order to properly start MongoDB as a service on Ubuntu 16.04, we also need to create a unit file that describes the service. Unit files tell the system a way to manage resources. The most common unit type is a service, which determines how to start or stop the service.

Create a configuration file called mongodb.service to set up the 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 use systemctl Start the newly created service as shown below -

$ sudo systemctl start mongodb

It usually returns no output. Now we need to check if the service has started normally. In order to perform 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.
