Install latest version (as of FEB 2019) of osTicket from GITHUB

cd /tmp/

wget https://github.com/osTicket/osTicket/releases/download/v1.11/osTicket-v1.11.zip

Unzip (defaults to ‘upload’ folder)

unzip osTicket-v1.11.zip  

Move it to apache web directory

sudo mv /tmp/upload /var/www/html/support

Set permissions

sudo chown apache: -R /var/www/html/support

Preinstall osTicket configs

cd /var/www/html/support/

sudo cp /var/www/html/support/include/ost-sampleconfig.php include/ost-config.php

Sets SELINUX to disable 

sed -i -r ‘s/SELINUX=enforcing/SELINUX=disabled/’ /etc/selinux/config

Update Firewall Rules

sudo firewall-cmd –zone=public –add-port=80/tcp –permanent

sudo firewall-cmd –reload

This next command is super important.  This resolves the error “is currently unable to handle this request.” When you try and login to (as of my testing) above 1.9.  If you have a different location name for your osTicket installation just alter the file path in the command.

sudo chmod -R 755 /var/www/html/support/

sudo chmod 0666 /var/www/html/support/include/ost-config.php
