PostgreSQL or Postgres is a powerful high-performance object-relational database management system (ORDBMS) released under a flexible BSD-style license. PostgreSQL is well suited for large databases and has many advanced features.

PostgreSQL is available for many operating systems including Linux, FreeBSD, Solaris, and Microsoft Windows.

PhpPgAdmin is a PHP based web application for managing PostgreSQL databases. With Phppgadmin, it is easy to create a database, create a role and create tables in Postgres.

This tutorial will show the installation of PostgreSQL and its web-based administration interface phpPgAdmin on Ubuntu 15.04.

Prerequisites

  • Ubuntu Server 15.04.
  • Root/Sudo access.

What we will do in this tutorial:

  1. Install PostgreSQL, phpPgAdmin and Apache2.
  2. Configure a PostgreSQL User.
  3. Configure Apache2.
  4. Configure phpPgAdmin.
  5. Testing.

Step 1 – Installing PostgreSQL, phpPgAdmin and Apache2

PostgreSQL and PhpPgAdmin are available in the Ubuntu repository. So you just need to install them with the apt command.

sudo apt-get install postgresql postgresql-contrib phppgadmin

The above command will automatically install all packages needed by PostgreSQL, like Apache, PHP etc.

Step 2 – Configure PostgreSQL user

PostgreSQL uses role for user authentication and authorization, it just like Unix-Style permissions. By default, PostgreSQL creates a new user called “postgres” for basic authentication. To use PostgreSQL, you need to login to the “postgres” account, you can do that by typing:

sudo su
su – postgres

Now you can access the PostgreSQL prompt with the command:

psql

And then change the password for postgres role by typing :

\password postgres

ENTER YOUR PASSWORD
