OpenVidu Single Node PRO on Oracle Cloud Infrastructure — Step-by-step Guide#

This page explains how to create a VM in Oracle Cloud Infrastructure (OCI), configure networking, and prepare it for OpenVidu Single Node PRO. Installing, administering, and upgrading OpenVidu Single Node PRO itself is covered in the On-Premises documentation.

Overview / prerequisites#

  • OCI account with permission to create compute instances and networking resources.

1. Create the VM (compute instance)#

  1. Log in to your Oracle Cloud Infrastructure account.
  2. Search for Instances and open it, then click "Create instance".
    OCI create instance
  3. Set a name for the instance (for example, openvidu-singlenode), or keep the default name.
  4. Change the image to Ubuntu "Canonical Ubuntu 24.04".
    Instance select image

  5. Select the shape for your OpenVidu server. We recommend 1 OCPU or more and at least 4 GB of RAM for OpenVidu to run correctly. Then click "Next".

    Note

    You can also use ARM-based instances. OpenVidu supports ARM, and the Always Free-eligible tier includes an ARM instance at no cost.

  6. In the Security tab, keep the default options and click "Next".

  7. Create a new VNIC with a new virtual cloud network and a new public subnet.
    Network configuration
  8. Scroll down and download the private key for the new instance so that you can connect via SSH. Then click "Next".
    Download SSH key
  9. In the Storage tab, select "Specify a custom boot volume size" and set it to 100 GB instead of 50 GB. You can keep 50 GB, but OpenVidu may fail due to insufficient disk space. Then click "Next".
    Volume size configuration
  10. Review the configuration and click "Create".

2. Attach a public IP address to the instance#

  1. Open the instance details and go to the VNIC resource, then to the "Networking" tab.
    VNIC location
  2. Open the "IP administration" tab. In the row of the existing IPv4 address, click the three dots menu and select "Edit".
    Edit IPv4
  3. Select "Ephemeral public IP" and click "Update".
    Create Ephemeral Public IPv4

3. Port rules in the network security lists#

OpenVidu and WebRTC require specific inbound rules on the instance network security (OCI NSG or subnet security list) and on the instance firewall (configured later).

The minimum inbound ports to allow must be included in the NSG rules.

  1. From the instance "Details" page, click the "Virtual cloud network" resource.
    VCN location
  2. Go to the "Security" tab and click the default security list.
    Security tab
  3. In the "Security Rules" tab, add the following Ingress rules.
Ingress Rules

Ingress rule 1
Ingress rule 2
Ingress rule 3
Ingress rule 4
Ingress rule 5
Ingress rule 6
Ingress rule 7
Ingress rule 8

4. SSH access, OpenVidu installation, and firewall rules#

Warning

Open the required ports before installing OpenVidu so you avoid connectivity issues.

  1. SSH into the instance:
ssh -i private_key_downloaded.key ubuntu@PUBLIC_IP
sudo apt update && sudo apt upgrade -y
  1. Install and start the firewall-cmd tool:
sudo apt install firewalld -y
sudo systemctl enable firewalld
sudo systemctl start firewalld
  1. Clean the existing iptables rules, accept all inputs, disable iptables persistence at startup, and restart the network service if required:
sudo iptables -F
sudo iptables -P INPUT ACCEPT
sudo systemctl disable netfilter-persistent
  1. Add the required firewall rules:
firewall-cmd --add-port=80/tcp
firewall-cmd --permanent --add-port=80/tcp

firewall-cmd --add-port=443/tcp
firewall-cmd --permanent --add-port=443/tcp

firewall-cmd --add-port=443/udp
firewall-cmd --permanent --add-port=443/udp

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

firewall-cmd --add-port=7881/tcp
firewall-cmd --permanent --add-port=7881/tcp

firewall-cmd --add-port=7885/udp
firewall-cmd --permanent --add-port=7885/udp

firewall-cmd --add-port=9000/tcp
firewall-cmd --permanent --add-port=9000/tcp

firewall-cmd --add-port=50000-60000/udp
firewall-cmd --permanent --add-port=50000-60000/udp
  1. Apply the rules and verify that they are correctly configured:
firewall-cmd --reload
firewall-cmd --runtime-to-permanent

firewall-cmd --list-all
  1. Follow the On-Premises install instructions to install OpenVidu PRO on the instance.

5. Administration and upgrade#
