# Red5 Pro Installation: Standalone, Cloud, and Cluster

> Install Red5 Pro as a standalone server, deploy to the cloud with Terraform, or set up a scalable cluster — with prerequisites and upgrade guidance.

Red5 Pro is a self-hosted live streaming server built on the open-source Red5 platform. You install and operate it on your own infrastructure — whether that is a single Linux server, a Windows machine, or a multi-node cluster spread across a cloud provider. This section walks you through every installation path so you can choose the approach that fits your use case.

## Prerequisites

Before you install Red5 Pro, make sure you have the following:

* **Java 21** (required for Red5 Pro 14.0.0 and later). Install OpenJDK 21 on Linux or the Oracle JDK on Windows. Earlier versions of Red5 Pro require Java 11 (versions 9.x–13.x) or Java 8 (versions 8.x and earlier).
* **A valid license key.** Red5 Pro will not start without one. Log in to your account at [account.red5.net](https://account.red5.net/overview) to find your key. Your `LICENSE.KEY` file is also bundled in the server ZIP download.
* **A 64-bit operating system.** Red5 Pro only supports 64-bit platforms.
* **Required inbound ports open** on your server or firewall:

| Port        | Protocol | Purpose                               |
| ----------- | -------- | ------------------------------------- |
| 5080        | TCP      | HTTP access and WebSocket for WebRTC  |
| 443         | TCP      | HTTPS and secure WebSocket for WebRTC |
| 1935        | TCP      | RTMP streaming                        |
| 8554        | TCP      | RTSP                                  |
| 40000–65535 | UDP      | WebRTC ICE / TURN / STUN              |

<Note>
  If you plan to use Let's Encrypt to obtain a free SSL certificate, you must also open port 80 temporarily during certificate issuance. You can close it again once the certificate is installed.

  <Card title="Standalone" icon="server" href="/red5-pro/installation/stand-alone">
    Install Red5 Pro directly on Linux, macOS (via Docker), or Windows. Best for development, testing, or single-server production deployments.
  </Card>

  <Card title="Cloud with Terraform" icon="cloud" href="/red5-pro/installation/cloud-terraform">
    Deploy a full Red5 Pro cluster to AWS, GCP, Azure, DigitalOcean, Linode, or OCI using official Terraform modules. Best for scalable production environments.

  <Card title="SSL configuration" icon="lock" href="/red5-pro/installation/ssl">
    Secure your server with an SSL certificate. Required for WebRTC — browsers will not grant camera or microphone access over plain HTTP.

    Configure Stream Manager 2.0 to orchestrate origin, edge, and relay nodes in an autoscaling cluster.

## Upgrading from a previous version

If you are running an older version of Red5 Pro, refer to the upgrade notes in the [standalone installation guide](/red5-pro/installation/stand-alone) before replacing your server binaries. Key points:

* **v14.0.0 and later** require Java 21. If you are upgrading from v13.x, you must install Java 21 before starting the upgrade.
* **Do not copy configuration files** from your old installation into the new one. Re-apply your changes manually to avoid overwriting new defaults.
* **SSL configuration changed in v14.0.0.** Versions before 14.0.0 required editing both `red5.properties` and `jee-container.xml`. From v14.0.0 onward, SSL is controlled entirely through `conf/red5.properties`.

<Tip>
  For a quick, automated deployment on Linux, use the [Red5 Pro Installer](https://github.com/red5pro/red5pro-installer) available on GitHub.
