osTicket comes with its own web-based installer to help guide you through the installation process without the frustration. While the installer provides step by step guide during the installation process, it’s important and helpful to have general knowledge about Web servers, PHP and MySQL.

CentOS 7:

Windows IIS:


To install osTicket, your web server must have PHP 8.x and MySQL 5.0 (or better) installed. If you are unsure whether your server meets these requirements, please check with your host or webmaster before proceeding with the installation.

You will need one MySQL database with valid user, password and hostname handy during installation. MySQL user must have FULL privileges on the database. If you are unsure whether you have these details or if the user has sufficient permissions, please consult your host or database admin before proceeding.


  1. PHP 8.1 for Windows Server 64-bit | 32-bit
  2. PHP 8.0 for Windows Server 64-bit | 32-bit
  3. MySQL 8.0 for Windows Server 64-bit
  4. MariaDB 10.9 for Windows Server 64-bit

Getting Started

At this point you should have downloaded latest version of osTicket. Uncompress the files and upload files and directories in upload folder to a directory of your choice on your server. For example /osticket/, /helpdesk/ or /support/ depending on your preference. Basic knowledge of using FTP is a plus at this stage. If you don’t know how to use FTP, we would recommend you read the documentation supplied with your FTP client and learn the basics of uploading and setting permissions on files.

osTicket installer needs to be able to write and modify ost-config.php found in the include directory. Please follow the instructions given by the installer.

Using Installation Script

Once all of the above steps are complete, you can complete the installation and basic setup in a web browser. You can invoke the installer by simply browsing the osTicket URL e.g Alternatively you can enter the URL to it into your browser address bar e.g

osTicket’s installation script will attempt to auto-detect paths and any permission issues. Please follow the instructions to finish up the installation process.

  1. If the script spots any configuration errors then it will not allow you to continue until the errors are corrected.
  2. If everything checks out, you will be presented with a form to fill in the required information.
  3. If any errors occurs, go back and check the data entered.
  4. On valid data the script will create and populate the database plus write a configuration file.

Note that the installer performs basic configuration required to get osTicket up and running. Further configuration is required, post-install, to make the system fully functional.

But before you get to it please take a second to cleanup.
