Install Koha Any Version on Ubuntu 20.04 LTS & Above.

Koha is the first Open Source Integrated Library Management System (ILMS) which includes Acquisition, Cataloguing, Circulation, Serial Control & Online Public Access Catalogue with many more advanced features. Koha supports International library standards and protocols which ensures interoperability between Koha & any other library management system. It supports technologies and international standards such as MARC 21, RFID, z39.50, web 2.0, etc. The software is fully customizable and includes all modules expected in any standard library management system.

Ubuntu package commands:

NB: these commands have been tested with the latest Ubuntu LTS ( 20.04 Focal Fossa)

Open Applications > System Tools > Terminal and execute the below commands one by one

Update Ubuntu using apt

sudo apt update && sudo apt upgrade -y

Clear the apt-get packager manager cache

sudo apt clean

Install MariaDB-server dependence

sudo apt install -y mariadb-server

Provide MySQL/MariaDB root password

(If the password asks during the installation process, enter the password in the window. Apply the following command, if the password window did not appear during the installation secure it)

Securing MariaDB

Run this command to improve the security of the MariaDB installation:

sudo mysql_secure_installation

(The script will prompt you to set up the root user password, remove the anonymous user, restrict root user access to the local machine and remove the test database. In the end, the script will reload the privilege tables ensuring that all changes take effect immediately. All steps are explained in detail and it is recommended to answer “Y” (yes) to all questions.)

Add Koha community repository (If you want stable/latest version of koha change oldstable to stable)

sudo echo deb http://debian.koha-community.org/koha oldstable main | sudo tee /etc/apt/sources.list.d/koha.list

Add trusted repository key

sudo wget -O- http://debian.koha-community.org/koha/gpg.asc | sudo apt-key add -

If you use Ubuntu version 22.04 LTS please run the below command.

sudo sh -c 'wget -qO - https://debian.koha-community.org/koha/gpg.asc | gpg --dearmor -o /usr/share/keyrings/koha-keyring.gpg'

Add trusted repository key

sudo sh -c 'echo "deb [signed-by=/usr/share/keyrings/koha-keyring.gpg] https://debian.koha-community.org/koha oldstable main" >> /etc/apt/sources.list.d/koha.list'

Update software repository

sudo apt update

Install Koha and dependencies

sudo apt install -y koha-common

( takes 5 mins on a reasonably fast internet connection )

Edit initial config file

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

Edit INTRAPORT as 8080, OPACPORT as 80, domain, and Memcached [for database, makes Koha faster] settings depending on install

Ensure rewrite and cgi are enabled

sudo a2enmod rewrite cgi

 

Restart Apache to take effect

sudo systemctl restart apache2

Setup the database for Koha

sudo koha-create --create-db library

Add new 8080 port (for IP based install) to Apache

sudo vim /etc/apache2/ports.conf

( need to add Listen 8080 below Listen 80 )

Enable Virtual-host on Apache

sudo a2dissite 000-default && sudo a2enmod deflate && sudo a2ensite library && sudo systemctl restart apache2

Test to ensure everything is working

In the web browser, visit http://localhost or http://127.0.0.1 {Koha maintenance message}
In the web browser, visit localhost:8000 or 127.0.0.1:8000 It will prompt for username & password

username --> koha_library
password --> get it executing below command –>

sudo koha-passwd library

Follow onscreen instructions/wizard create a library and a super librarian

Change Koha Master Password (optional)

Koha master password can be changed by editing the koha-conf.xml file

sudo sed -i 's/1MvFLNny4naqemo@/prasan123/g' /etc/koha/sites/library/koha-conf.xml 

(for single click changing password, use this command)

OR  manually change

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

Under config, section find out the line password and change it

<config>

 <hostname>localhost</hostname>
 <port>3306</port>
 <user>koha_library</user>
 <pass>1MvFLNny4naqemo@</pass> 

( change default password 1MvFLNny4naqemo@ to prasan123 ) save it

then change MySQL privileges

sudo mysql -uroot -p 

[enter the MySQL Root password]

use mysql;

SET PASSWORD FOR 'koha_library'@'localhost' = PASSWORD('prasan123');

flush privileges;

quit;

Restart Memcached Apache2 and MySQL 

sudo systemctl restart memcached apache2 mysql
