How To Install PostgreSQL on Ubuntu 14.04

Install PostgreSQL on Ubuntu 14.04

In this tutorial, we will show you how to install PostgreSQL on Ubuntu 14.04 LTS. For those of you who didn’t know, 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 the step-by-step installation of PostgreSQL on Ubuntu 14.04.

Prerequisites

  • A server running one of the following operating systems: Ubuntu 14.04.
  • It’s recommended that you use a fresh OS install to prevent any potential issues.
  • SSH access to the server (or just open Terminal if you’re on a desktop).
  • A non-root sudo user or access to the root user. We recommend acting as a non-root sudo user, however, as you can harm your system if you’re not careful when acting as the root.

Install PostgreSQL on Ubuntu 14.04

Step 1. First, update our local apt repository.

sudo apt-get update

Step 2. Install the PostgreSQL server.

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

sudo apt-get install postgresql postgresql-contrib

Step 3. Access PostgreSQL command prompt.

Once the installation is completed, you can start using PostgreSQL 9.4 on your ubuntu 14.04 by typing the commands:

sudo -u postgres psql

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

\conninfo

Create a new user and database.

### For example, let us create a new user called “idroot” with password “idrootnet”, and database called “idrootdb”. ###

sudo -u postgres createuser -D -A -P idroot
sudo -u postgres createdb -O idroot idrootdb

Congratulations! You have successfully installed PostgreSQL Server. Thanks for using this tutorial for installing PostgreSQL in ubuntu 14.04 systems. For additional help or useful information, we recommend you check the official PostgreSQL website.
