This guide is for installing the v1.10 of the osTicket software which is the one that is live at the moment of the writing of this Wiki.

sudo apt update && sudo apt upgrade -y
sudo apt install -y lsb-release ca-certificates apt-transport-https software-properties-common gnupg2 curl wget unzip

Since it is an old version and is no longer distributed we will have to installit through a repository.

curl -sSL https://packages.sury.org/php/README.txt | sudo bash -x
sudo apt update

sudo apt install -y apache2 mariadb-server

sudo apt install -y php5.6 php5.6-cli php5.6-mysql php5.6-fpm php5.6-xml php5.6-mbstring php5.6-gd php5.6-imap php5.6-json php5.6-apcu php5.6-intl php5.6-mcrypt libapache2-mod-php5.6

sudo a2enmod php5.6
sudo systemctl restart apache2

For this installation we will use a dump of a already existing database.

sudo mysql -u root -p

CREATE DATABASE osticket_db;
CREATE USER 'osticket_user'@'localhost' IDENTIFIED BY 'passsword_of_ur_choice';
GRANT ALL PRIVILEGES ON osticket_db.* TO 'osticket_user'@'localhost';
FLUSH PRIVILEGES;
EXIT;

Now we can import the dump.sql into the databse we just created (if you don't have a dump skip this).

mysql -u osticket_user -p osticket_db < /path/to/dump.sql

wget https://github.com/osTicket/osTicket/releases/download/v1.10/osTicket-v1.10.zip
unzip osTicket-v1.10.zip -d osticket
sudo mv osticket/upload /var/www/html/osticket

sudo mv /var/www/html/osticket/include/ost-sampleconfig.php /var/www/html/osticket/include/ost-config.php

sudo nano /var/www/html/osticket/include/ost-config.php

define('DBTYPE','mysql');
define('DBHOST','localhost');
define('DBNAME','osticket_db');
define('DBUSER','osticket_user');
define('DBPASS','passsword_of_ur_choice');
define('TABLE_PREFIX','ost_');
define('OSTINSTALLED',TRUE);
define('SECRET_SALT','uKVB7ZnvozppfEOzuyWVVZlZX81thj6p'); (put this exact string to uncrypt the tickets)
define('ADMIN_EMAIL','ur_email@example.com');

sudo chown -R www-data:www-data /var/www/html/osticket/

sudo chmod 0644 /var/www/html/osticket/include/ost-config.php

sudo rm -rf /var/www/html/osticket/setup/

Search on a browser the URL/osticket and if you had the sql dump everything should be operative. If this was the first install follow the instruction the osTicket wizard tells you.

This section is for the OsTicket and Php update (only for OsTicket version older than the 1.6). The first thing to do is to on the admin pannel and disable the service.

sudo apt update
sudo apt install -y php8.4 php8.4-cli php8.4-mysql php8.4-fpm php8.4-xml php8.4-mbstring php8.4-gd php8.4-intl php8.4-apcu php8.4-bcmath libapache2-mod-php8.4

sudo a2dismod php5.6
sudo a2enmod php8.4
sudo systemctl restart apache2

cd /tmp
wget https://github.com/osTicket/osTicket/releases/download/v1.18.4/osTicket-v1.18.4.zip

(ofc check if the link is the right version)

Unzip the files

unzip osTicket-v1.18.4.zip -d osticket_new

Save a config copy

cp /var/www/html/osticket/include/ost-config.php /tmp/ost-config.bak

Overwrite the files in the osticket folder

sudo cp -r /tmp/osticket_new/upload/* /var/www/html/osticket/

Put the old config file

sudo cp /tmp/ost-config.bak /var/www/html/osticket/include/ost-config.php

sudo chown -R www-data:www-data /var/www/html/osticket/

Now you will have to access the admin pannel and there will be a voice that says to start the update. Do it.

Do this only after a few minutes the end of the update on the platform

sudo rm -rf /var/www/html/osticket/setup/

sudo chmod 0644 /var/www/html/osticket/include/ost-config.php
