Category: Support System

osTicket is one of the great open source support system, very easy to install and use.  I have noted the whole process, short version, and detailed version.  What you will need from start to finish.  This installation is fresh, without any add-ons or any customization osTicket version 1.10.1.  I have written this installation based on Ubuntu 16.04 with Apache as a web server, it may work just fine with other versions of Ubuntu servers or similar to other flavors of Linux systems.  Assuming you have your web server and domain up and running without any issues.  So, let’s get started

What you will need

• Server requirements:  You can get up to date from official docs from osTicket very well documented
  • PHP 5.6 (or better I am going to be using PHP7.0)
  • MySQL 5.0 (or better)
  • 2GB memory recommended 4GB or more
• Access to web/database server via SSH
• Access to site file via (FTP, SFT, GUI, SSH, etc. …)

Getting server ready to install osTicket:

Installing requirements, you may need to run add this to repository void error, log in to your web server via SSH

Commands:
sudo apt-add-repository ppa:ondrej/php
sudo apt-get install php7.0-gd php7.0-imap php7.0-xml php7.0-mbstring php7.0-intl php–apcu

Downloading osTicket:

https://osticket.com/download/
Once you have downloaded then extract it or upload it to your web server common location: /var/www/

Then set the permission:

commands: make sure to change /var/www/ to your path
sudo chown -R www-data:www-data /var/www/

Click Continue once you have fixed any issues, please correct it before going forward

Setup osTicket Database and give full permission using whichever tool you are comfortable with it, then fill in details and click Install now

if everything went well you should see Congratulation, then just change the permission of your config file

You should be able to login to your osTicket support system with the information you used earlier, see my notes, where I have put in some common issues you may encounter when installing.

Notes and common errors/solution: 

You may need to do these if you get errors or other settings changes

You will also need to make sure that ost-config.php has correct permission, otherwise, you will get this message:

if you have already installed the PHP IMAP extension and still gives you an error, take a look at your php.ini file and enable it by uncommenting : /etc/php/php.ini:
;extension=imap.so
to

You may need to restart the web service after making changes to take effect:
