How To Install MongoDB 4.0. on Ubuntu 18.04 LTS

MongoDB is a cross-platform document-oriented database program. Classified as a NoSQL database program, MongoDB uses JSON-like documents with schemata. MongoDB is developed by MongoDB Inc. and licensed under the Server Side Public License (SSPL).

MongoDB is a NoSQL document-oriented database. Refers to a database with a data model other than the tabular format used in relational databases such as MySQL, PostgreSQL, and Microsoft SQL. MongoDB features include: full index support, replication, high availability, and auto-sharding. It is a cross-platform and it makes the process of data integration faster and much easier. Since it is free and open-source, MongoDB is used by number of websites and organizations.

This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo’ to the commands to get root privileges. I will show you through the step by step installation MongoDB on a Ubuntu 18.04 LTS (Bionic Beaver) server.

Install MongoDB on Ubuntu 18.04 LTS

Step 1. First make sure that all your system packages are up-to-date

sudo apt-get update
sudo apt-get upgrade

Step 2. Install MongoDB on Ubuntu 18.04 LTS.

First to completely remove an existing Mongodb from your machine if you have that in already:

sudo apt-get remove mongodb
sudo apt-get autoremove

A stable version of MongoDB packages are already in the default Ubuntu repository. However, the version in Ubuntu’s repository isn’t the latest. If you want to install the latest version you must add a third-party repository to your system and install it from there:

sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv 0C49F3730359A14518585931BC711F9BA15703C6

After adding the repository key to Ubuntu, run the commands below to add MongoDB repository to your system:

echo "deb http://repo.mongodb.org/apt/ubuntu trusty/mongodb-org/3.4 multiverse" | sudo tee /etc/apt/sources.list.d/mongodb-org-3.4.list

After that, update your system and refresh existing repositories by running the commands below:

apt update

And now install the latest stable version of MongoDB:

apt install -y mongodb-org

Step 3. Verifying MongoDB database.

After installing MongoDB, the commands below can be used to stop, start and enable MongoDB to automatically startup when the systems boots up:

# sudo systemctl start mongod.service
# sudo systemctl enable mongod.service
# sudo systemctl status mongod.service
● mongodb.service - LSB: An object/document-oriented database
   Loaded: loaded (/etc/init.d/mongodb; bad; vendor preset: enabled)
   Active: active (running) since Thu 2016-06-4 16:40:35 IST; 14s ago
     Docs: man:systemd-sysv-generator(8)
  Process: 2849 ExecStart=/etc/init.d/mongodb start (code=exited, status=0/SUCCESS)
  Main PID: 1593 (code=exited, status=0/SUCCESS)
    Tasks: 13 (limit: 512)
   Memory: 51.9M
      CPU: 100ms
   CGroup: /system.slice/mongodb.service
           └─2861 /usr/bin/mongod --config /etc/mongodb.conf

A good way to start using MongoDB on your Ubuntu 16.04 is to read the MongoDB manual on the official web site.

How To Install PostgreSQL 11.2 on Ubuntu 18.04 LTS

PostgreSQL is a free, open-source object-relational database management system (object-RDBMS), similar to MySQL, and is standards-compliant and extensible. It is commonly used as a back-end for web and mobile applications. PostgreSQL, or ‘Postgres’ as it is nicknamed, adopts the ANSI/ISO SQL standards together, with the revisions.

This article assumes you have at least basic knowledge of linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo’ to the commands to get root privileges. I will show you through the step by step installation PostgreSQL on a Ubuntu 18.04 (Bionic Beaver) server.

Install PostgreSQL on Ubuntu 18.04 LTS

Step 1. First make sure that all your system packages are up-to-date

sudo apt-get update
sudo apt-get upgrade

Step 2. Installing PostgreSQL server on Ubuntu 18.04 LTS.

PostgreSQL is available in the default repositories. So enter the following command from the Terminal to install it:

apt install postgresql postgresql-contrib phppgadmin

Step 3. Access PostgreSQL command prompt.

After installing PostgreSQL database server, by default it creates a user ‘postgres’ with role ‘postgres’. It also creates a system account with same name ‘postgres’. So to connect to postgres server, login to your system as user postgres and connect database:

su - postgres
psql

Now you are logged in to PostgreSQL database server. To check login info use following command from database command prompt:

postgres-# \conninfo

To disconnect from PostgreSQL database command prompt just type below command and press enter. It will return you back to Ubuntu command prompt:

postgres-# \q

Create new user and database:

### For example, let us create a new user called “mona” with password “ramona”, and database called “monadb”. ###
sudo -u postgres createuser -D -A -P mona
sudo -u postgres createdb -O mona monadb

Step 4. Configure Apache2 for phpPgAdmin.

phpPgAdmin is a web-based administration tool for PostgreSQL. It is perfect for PostgreSQL DBAs, newbies, and hosting services. You need to configure apache for phpPgAdmin. Edit the file /etc/apache2/conf-available/phppgadmin.conf:

nano /etc/apache2/conf-available/phppgadmin.conf

Comment out the line #Require local by adding a # in front of the line and add below the line allow from all so that you can access from your browser:

Step 5. Configure phpPgAdmin.

Next, edit the file /etc/phppgadmin/config.inc.php:

nano /etc/phppgadmin/config.inc.php

Now change the following option:

$conf[‘extra_login_security'] = true;
to
$conf[‘extra_login_security'] = false;

Now, we can restart Apache and phpPgAdmin so that the changes take place:

systemctl restart postgresql
systemctl restart apache2
systemctl enable postgresql
systemctl enable apache2

Step 6. Accessing phpPgAdmin.

phpPgAdmin will be available on HTTP port 80 by default. Open your favorite browser and navigate to http://yourdomain.com/phppgadmin or http://server-ip/phppgadmin. If you are using a firewall, please open port 80 to enable access to the control panel.

Congratulation’s! You have successfully installed PostgreSQL Server. Thanks for using this tutorial for installing PostgreSQL in Ubuntu 18.04 (Bionic Beaver) systems. For additional help or useful information, we recommend you to check the official PostgreSQL web site.
