Site Admin 26.3
Site Admin Installation Guide

# External Requirements

Before you install Site Admin, you must install and configure the following components and software, either on the same server on which you intend to install Site Admin, or on a separate server.

## Knowledge Discovery Components

Site Admin requires access to the following Knowledge Discovery components.

- Community component 26.3. Community manages users in Site Admin.
- Agentstore component 26.3. Agentstore is an Content component, configured to store user details for Community.
- Coordinator 26.3. Coordinator is a central monitoring service from which you can view the logs, manage components, and monitor the status of components in your Knowledge Discovery system. Site Admin uses this service to provide information about your system.
- Controller 26.3. Controller is installed on each machine that hosts Knowledge Discovery services. It monitors the services on that machine and communicates with Coordinator.

OpenText recommends that you install a separate instance of Community and Agentstore specifically for use with Site Admin, and that you configure the Community data DRE to point at your Agentstore.

NOTE: Site Admin requires TCP-only network access to the Community and Coordinator components. Site Admin does not require network access to Agentstore or any Controller components.

For information about how to install Community and Agentstore, refer to the Getting Started Guide. For information about how to install Site Admin separately, see Install Site Admin. For information about how to install Controller and Coordinator separately, see Install Controller and Coordinator.

NOTE: To install Agentstore from a ZIP package, you download and install the Content component, and then rename the executable and configuration files (for example, rename `content.exe` to `agentstore.exe`).

## Third-Party Software

- Java 17 or 21 must be installed on the machine hosting Site Admin.
- (Optional) PostgreSQL (versions up to 17.x). Site Admin uses a database to store information on task history, alerts, groups, and server details. By default, Site Admin uses an embedded database but you can use a PostgreSQL database if you prefer.
- SMTP Server. An SMTP server is required for email alerting.

NOTE: Site Admin requires TCP-only network access to PostgreSQL and SMTP Server.

## Site Admin Home Directory

You must define a new directory to use as the Site Admin home directory. This directory contains the Site Admin configuration file (`config.json`), and a `logs` subfolder that contains the Site Admin log files.

OpenText recommends that you set the home directory as follows:

- Linux: `/opt/siteadmin/home`
- Windows: `C:\ProgramData\SiteAdmin`

The location of the home directory is required during the installation process; see Install Site Admin for more information.
