This system empowers businesses to efficiently manage, organize, and archive all support requests and responses, ensuring customers receive the prompt and accountable service they deserve.

To deploy osTicket, ensure your server meets the following requirements:

  • HTTP server (Microsoft® IIS or Apache)
  • PHP version 8.2 - 8.4 (8.4 recommended) with mysqli extension
  • MySQL database version 5.5 or greater

Recommended PHP extensions include ctype, fileinfo, gd, gettext, iconv, imap, intl, json, mbstring, Zend OPcache, phar, xml, xml-dom, and zip. APCu module is also recommended.

The easiest way to install and track updates is by cloning the public repository. Navigate to an empty folder on your web server and execute:

git clone https://github.com/osTicket/osTicket

Then, deploy the code to your server's www root folder, for example:

cd osTicket
php manage.php deploy --setup /var/www/htdocs/osticket/

After deployment, configure your server to serve the folder and visit the page to complete the installation. You can then delete the setup/ folder from the deployment location.

How osTicket Works

osTicket simplifies the support process through a clear workflow:

  1. Users create tickets: Customers can submit their inquiries through your website, email, or by phone.
  2. Incoming tickets are saved and assigned: All new tickets are automatically saved within the system and can be assigned to appropriate agents.
  3. Agents resolve issues: Support agents use the web interface to manage tickets, communicate with users, and resolve their issues efficiently.

This system ensures that all support interactions are centralized and easily trackable.
