osTicket is one of the leading open source ticketing systems. Here’s an easy way to spin up an instance on Ubuntu.

Note:
This script is purely intended for use in short-lived demo systems. The passwords are obvious (password !?) and there is no hardening applied to any of this system. DO NOT USE THIS SCRIPT IN PRODUCTION.

Create Shell Script
Spin up an Ubuntu instance then create a new shell script and give it executable permissions:

touch osTicket.sh
chmod +x osTicket.sh

Script Content
Paste this into the script:

#!/usr/bin/env bash

sudo apt update -y
sudo apt install unzip apache2 php7.2 php7.2-mysql mysql-server -y
sudo a2enmod rewrite
sudo rm /var/www/html/index.html
mkdir osticket && cd osticket
wget https://github.com/osTicket/osTicket/releases/download/v1.14.1/osTicket-v1.14.1.zip
unzip osTicket-v1.14.1.zip
sudo mv upload/* /var/www/html
sudo mv /var/www/html/include/ost-sampleconfig.php /var/www/html/include/ost-config.php
sudo chmod 0666 /var/www/html/include/ost-config.php
sudo mysql -u root -e "CREATE DATABASE osticket;"
sudo mysql -u root -e "CREATE USER 'osticket'@'localhost' IDENTIFIED BY 'password';"
sudo mysql -u root -e "GRANT ALL PRIVILEGES ON * . * TO 'osticket'@'localhost';"
sudo chown ubuntu:ubuntu /etc/apache2/sites-available/000-default.conf
cat <<EOF >> /etc/apache2/sites-available/000-default.conf
<Directory /var/www/>
AllowOverride All
</Directory>
EOF
sudo service apache2 restart

Install via UI
Open a browser and navigate to http://IPADDRESS/setup and follow the wizard.

The script has created a database already (I advise adjusting these details for security):

Database Name: osticket
Database User: osticket
Database Password: password

Note: You may get an HTTP 500 error during the install. That’s fine. Just refresh the page and it’ll work.

Cleanup after Install
After the installation, you’ll need to delete the setup directory and reset some file permissions. Just run this:

sudo rm -rf /var/www/html/setup
sudo chmod 0644 /var/www/html/include/ost-config.php

Conclusion
At this point, you should have a fully working osTicket installation. Enjoy!
