Preparing Cluster Servers

We need to prepare the Linux servers for installing the following cluster application servers:

• Media Servers

• Queue Servers

• Meeting Servers

• IVR servers

• IM Server

Supported Linux OS

• Ubuntu 22.04, 24.04

• Debian 11.x, 12.x

It only supports 64-bit OS.

When setting up the PBX cluster, please ensure there is sufficient network speed and bandwidth between the servers. Insufficient network resources may cause the PBX to not work as expected.

Preparing the Linux Host Machine for Installation

Tasks that MUST be completed before installing cluster servers.

• Ensure the server date-time is synced correctly.

• If the Linux server is on a LAN, assign a Static Private IP address.

• For the media server cluster, each media server also needs a Static Public IP address if you want the user to call from the Internet.

• Install all available updates and service packs before installing the cluster server.

• Do not install PostgreSQL on the Server.

• Ensure that all power-saving options for your system and network adapters are disabled (by setting the system to High-Performance mode).

• Do not install TeamViewer, VPN, or similar software on the host machine.

• The server must not be installed as a DNS or DHCP server.

Setup the Docker Environment

On each server, execute the below commands to download the installation scripts:

sudo curl \
https://raw.githubusercontent.com/portsip/portsip-pbx-sh/master/v22.x/init.sh  \
-o  init.sh

sudo /bin/sh init.sh

Execute the below command to install the Docker-Compose environment. If you get the prompt likes*** cloud.cfg (Y/I/N/O/D/Z) [default=N] ?, enter the Y, and then press the Enter button.

cd /opt/portsip

sudo /bin/sh install_docker.sh
