# Installing DSO with mod_ruid2 using EasyApache 4

## In This Tutorial:

[Install DSO/mod_ruid2](#install-dso-modruid2) [Confirm DSO Available](#confirm-dso-available) [Set DSO Handler](#set-dso-handler)

**Dynamic Shared Object (DSO)** is an Apache module that is used to handle PHP scripts. It is one of a few [PHP Handlers available to choose from](/support/website/choosing-the-best-php-handler/). Its major benefits are speed and the ability to use OpCode caching. When implemented with the Apache module, **Mod_Ruid2**, DSO can be utilized more securely. In this guide, you will learn how to install DSO with Mod_Ruid2 using EasyApache 4.

**NOTE: **A [VPS](https://www.inmotionhosting.com/vps-hosting) or [Dedicated Server](https://www.inmotionhosting.com/dedicated-servers) with [root access](/support/amp/obtain-root-access/) is required to follow the steps in this guide.
