You must use the PHP Agent RPM installer as the root user.

You pass configuration settings for the agent to the installer using environment variables rather than command-line arguments. Before starting—or as part of your installation script—you need to set the environment variables. You can configure settings such as node name, tier name, business application name, and others for the agent. However, the installer will provide sensible defaults if not provided.

The RPM installer determines the location of your PHP installation based on the PATH environment variable. It uses the first PHP installation that it encounters in the PATH to configure the installer. If you have installed PHP in a non-standard location, you must provide the directory of your PHP binary in the APPD_PHP_PATH environment variable.

Before starting, get the RPM package from the Splunk AppDynamics Download Portal.
