How to Install Flussonic on CentOS 7 (Step-by-Step Guide)

Flussonic is a professional-grade video streaming server used by broadcasters, surveillance systems, and live TV platforms worldwide. Unlike open-source alternatives like Wowza or Nimble Streamer, Flussonic offers real-time transcoding, DVR functionality, adaptive bitrate streaming, and robust API support – making it ideal for enterprise-level deployments.

In this comprehensive guide, you’ll learn how to install and configure Flussonic Streaming Server on CentOS 7, including prerequisites, repository setup, firewall configuration, and post-installation optimization.

Whether you’re building a live IPTV platform, a security camera network, or a webinar broadcasting system, this guide will get you up and running fast.

What Is Flussonic?

Flussonic is developed by Alteamedia and is widely used in industries that require low-latency, high-concurrency video streaming. It supports:

RTSP, RTMP, HLS, DASH
Real-time video transcoding
Time-shifted TV (DVR)
MPEG-TS over UDP/RTP
REST API for automation
Multi-CDN integration

It’s trusted by media companies, telecom providers, and government agencies due to its stability, scalability, and security.

Compared to free solutions like GStreamer or FFmpeg pipelines, Flussonic provides a managed, production-ready environment with monitoring, logging, and failover capabilities.

Prerequisites for Installing Flussonic

Before installing Flussonic, ensure your server meets these requirements:

OS	CentOS 7 (64-bit)
Architecture	x86_64
RAM	Minimum 2GB (4GB+ recommended)
Storage	SSD preferred for transcoding
Network	1Gbps port (for high-bitrate streams)
Access	Root or sudo privileges
License	Valid Flussonic license key

For high-traffic streaming, use a dedicated server with NVMe SSD and 1Gbps+ bandwidth.

Step-by-Step Installation Guide

Follow these steps to install Flussonic on CentOS 7.

Step 1: Add the Flussonic Repository

echo "[flussonic]

name=Flussonic by Alteamedia

baseurl=https://repo.flussonic.com/centos/7/x86_64/

gpgcheck=1

gpgkey=https://repo.flussonic.com/RPM-GPG-KEY" > /etc/yum.repos.d/flussonic.repo

This adds the official Flussonic package repository to your system.

Step 2: Import the GPG Key

To verify package integrity, import the GPG key:

rpm --import https://repo.flussonic.com/RPM-GPG-KEY

Step 3: Install Flussonic

Now install the Flussonic package:

yum install flussonic

The installer will download and set up all dependencies automatically.

Step 4: Start and Enable the Service

After installation, start Flussonic and enable it to launch at boot:

systemctl start flussonic

systemctl enable flussonic

Check the status:

systemctl status flussonic

You should see: active (running).

Step 5: Access the Web Interface

Open your browser and go to:

http://your-server-ip:8080

You’ll see the Flussonic dashboard where you can:

Add streams
Configure transcoding profiles
Set up DVR archives
Monitor active connections
View logs and bandwidth usage

Configuring a Live Stream in Flussonic

Let’s create a simple RTMP ingest stream:

Go to Streams > Create New Stream
Enter stream name: mylive
Set source: rtmp://your-server-ip/live/mystream
Choose output formats: HLS, DASH
Save and start streaming using OBS or any RTMP encoder

Now you can embed the player on your site using:

<video src="http://your-server-ip:8080/mylive/playlist.m3u8" controls></video>

Or use the built-in HTML5 player generator.

Licensing – How to Request / Activate a Flussonic Trial License Key

Flussonic offers licenses for both paid and trial versions. To use the software beyond initial installation or demo mode, you will need a valid license key.

Steps to request / activate the trial license:

Sign up via the Flussonic website – In your account area (my.flussonic.com), request a trial license. The free trial key gives you full feature access for a limited period.
Install Flussonic and start the service (e.g. via service flussonic start) if not already running.
Open the Web UI: use the browser to connect to http://YOUR_SERVER_IP:80 or with manual domain.
Enter license key: in the UI, Flussonic will prompt for the license key, administrator username + password during activation. Insert the key that usually starts with g4|
Possible USB-key option: If using a USB-based license, copy necessary rules, insert the USB key, then upload activation file in the UI.

Please note:

Use login and password without special chars like @, ;, #, [, \, /, =, $ when activating.
For offline or clustered setups, you may need to upload activation files or migrate the license.

System Monitoring – Flussonic’s Built-in Monitoring Dashboard (Retroview etc.)

Flussonic comes with tools (e.g. Retroview) for system monitoring that help you see how your server is performing in real time.

What you can monitor:

CPU Load / Memory Usage – Helps you see if the server is overloaded.
Disk Utilization / I/O Metrics – Important especially when using DVR or heavy recording.
Number of active streams / clients – You see how many users are connected.
Bandwidth usage – Monitor outgoing traffic to spot bottlenecks.
Error rates / DVR errors – If writing fails, segments missing, etc.

Why this matters:

Helps you plan scaling (add hardware, more servers) before failure.
Helps detect streaming issues early (latency, buffering).
Supports troubleshooting: Is the server high-CPU or is the network the problem?

SSL Setup – Secure Streaming with HTTPS (Let’s Encrypt + Nginx Reverse Proxy)

Flussonic supports SSL directly for its admin UI and streaming listener ports. Additionally, you can front Flussonic via Nginx reverse proxy to deliver HLS/DASH/etc over HTTPS more securely. Flussonic also offers built-in Let’s Encrypt support.

Built-in Let’s Encrypt (Flussonic):

In the UI, go to Config → TLS-tunneled protocols section.
Click “Issue by Let’s Encrypt” button. It verifies via domain (must be listening on HTTP port 80).
After issuing, Flussonic auto-refreshes/renews the certificate when it expires.

Using Nginx as Reverse Proxy:

You can place Nginx in front of Flussonic to handle HTTPS termination, load balancing, caching, etc. Here is a simplified config sample:

server {
    listen 443 ssl;
    server_name yourdomain.com;

    ssl_certificate /etc/letsencrypt/live/yourdomain.com/fullchain.pem;
    ssl_certificate_key /etc/letsencrypt/live/yourdomain.com/privkey.pem;

    location / {
        proxy_pass http://127.0.0.1:8080;  # Flussonic HTTP port
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Forwarded-Proto $scheme;
    }
}

Ensure both port 80 (for Let’s Encrypt verification) and 443 are open in your firewall.
In Flussonic UI, also upload or set the SSL certificate for any listeners you want protected if using built-in SSL.

Security & Performance Tips

Secure Flussonic with a Firewall

Allow only necessary ports:

firewall-cmd --permanent --add-port=8080/tcp # Web UI

firewall-cmd --permanent --add-port=1935/tcp # RTMP

firewall-cmd --permanent --add-port=554/tcp # RTSP

firewall-cmd --reload

Optimize for High Load

Use SSD/NVMe storage for DVR buffering
Allocate more RAM if doing real-time transcoding
Use Nginx reverse proxy with SSL for secure HLS delivery
Enable Geo-blocking if needed

Troubleshooting Common Issues

Flussonic fails to start	Check `journalctl -u flussonic` for errors
Can’t access web UI	Ensure port 8080 is open in firewall
Stream not loading	Verify source URL and encoder settings
High CPU usage	Reduce transcoding profiles or upgrade CPU
