Use a scripts install 3cx on debian 10

Introduction

When 3CX was based on Debian 9 Stretch, the Debian 9 command-line installation of 3CX was officially supported, but after upgrading to Debian 10 Buster, 3CX has made deeper customization to the ISO and the command-line installation method has been officially removed from the official website.

Local installations can use the 3CX ISO, but many cloud providers do not support the ISO installation method. After we unpacked and analyzed the 3CX ISO, we found that the 3CX ISO was executing the installation script on the Debian 10 ISO.

So we are going to share how to install 3CX on a Debian 10 image using a script. the installation is the same as the official image installation.

Preparations

First you need to prepare the operating system for Debian 10.To install on a cloud server, just select the public image of Debian 10 in the mirror market and install it, or for a local installation, download it using the following link: debian-10.11.0-amd64-netinst.iso.

Installation by script

wget -O /tmp/post-install http://downloads.3cx.com/downloads/debian10iso/post-install_10.11.0_4b27dc5.txt

chmod +x /tmp/post-install

bash /tmp/post-install                                           
We can check if the script is installed successfully by executing the command：

ls -l /usr/bin/3CX* /etc/systemd/system/3CX*
The files in the image below all exist, indicating that there are no problems.

Then execute the following command to install 3CX:

bash /usr/local/bin/post-install
