Koha is an open source integrated library system (ILS), used world-wide by public, school and special libraries. The name comes from a Māori term for a gift or donation. ~ Wikipedia

In this blog post we will discuss how to Install the Latest Version of Koha (21.05.XX)

System Requirements

  • Ubuntu 18.04 + or Debian 9+
  • Maria DB 10.1 +
  • Perl 5.24 +

Installation of Koha is quite easy and simple you can install Koha on your Local Machine or a Virtual Machine / Cloud / Compute Engine, I recommend using a minimum of 4 Gb RAM based machine / virtual setup.


The System must have Ubuntu 18.04 + Operating System Installed.

Koha Installation Process

  • Update Operating System
    • sudo apt-get update
    • sudo apt-get upgrade
  • Add Koha Repositories
  • Install Database Server
    • sudo apt-get install -y mariadb-server
    • sudo mysqladmin -u root password <yourpassword>
  • Install Koha
    • sudo apt install -y koha-common

Configuration Considerations

Koha Provides 2 Services namely

  • Staff Portal : Portal Used by Staff for Library Services
  • Web OPAC : Portal Used by Patrons for OPAC Services

Both of these services are installed on a single system/server there are multiple ways to access these

  • Named Services
  • IP Port Based Services
    • Where you want to access both the Portals using Same IP but different Ports eg XX.XX.XX.XX (Web Opac), XX.XX.XX.XX:8080 (Staff Portal)

Generally the Staff Portal is restricted to your Local Network while Web OPAC is Publically available, in this tutorial we will be using IP Port Based Setup, Lets Start Configuring Koha

Basic Web Based Installation & Configuration

Change the Port No of Staff Portal to 8080

sudo vim /etc/koha/koha-sites.conf

Find the following line and edit


Create a Koha Instance

sudo koha-create --create-db library (you can change <library> to whatever name you want to give)

Add a Port to Apache

sudo vim /etc/apache2/ports.conf

Listen 8080

Enable Module & Sites

sudo a2dissite 000-default

sudo a2enmod deflate

sudo a2ensite library

sudo service apache2 restart

sudo service memcached restart

Web Installation

Detailed Guide available @

Once you are done with the above you can Open the Koha Web Installer to Install & Configure Koha to start the Web Installer open the following URL on your Favourite Web Browser (Replace with Actual IP of VM/External Machine if being used)

The Web Installer will require a username & password to continue your can get the same from the file /etc/koha/sites/library/koha-conf.xml

sudo vim /etc/koha/sites/library/koha-conf.xml

Find the Following to know the User & Password



The Web Installer will ask for various inputs like branch, itemtype, super user info, defaults, MARC Flavor and much more select/enter as per your preference and enjoy Koha.

Once Installation is Complete you can access

If your System is Connected to Network and proper firewall rules are in place then both the Staff Portal & Web OPAC will be available in your Local Network instantly. If you configured the above on a Cloud VM/Compute replace with the Public IP as available with you.
