Install Koha on Ubuntu

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.

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

Provide MySQL/MariaDB root password

(If the password asks during the installation process, enter the password in the window. Apply 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.)
