[How to] Install 3CX ISO on OVH's VPS

[Alphabetic]

Last updated: 29/08/2024

This is more for the benefit of me. However, I thought people might like to install their 3CX's with the ISO rather then using the old command lines.

You will need:-

- 3CX ISO
- OVH VPS LE YOU MUST CHOOSE DEBIAN 10 DISTRO OR YOU'LL GET GRAPHICS ERROR
- VNC Viewer (Im using UltraVNC)


Buy your VPS from OVH then reboot it in rescue mode

Use the login details from the email or you can grab them from the login screen on the KVM.



SSH to the VPS using Terminal/Powershell

ssh root@<IP> -L 5900:localhost:5900

Unmount and delete all partitions on HDD​

note you may have more/less partitions to delete

umount /dev/sdb1
fdisk -u /dev/sdb
d
d
w

Install KVM & download 3CX ISO​

sudo apt-get clean all
sudo apt-get update
apt install qemu-kvm

For v18

wget -P /dev https://downloads-global.3cx.com/downloads/debian10iso/debian-amd64-netinst-3cx.iso

For v20

wget -P /dev https://downloads-global.3cx.com/downloads/debian12iso/debian-amd64-netinst-3cx.iso

Start up the KVM​

For v18

qemu-system-x86_64 -netdev type=user,id=mynet0 -device virtio-net-pci,netdev=mynet0 -m 1024 -enable-kvm -drive index=0,media=disk,if=virtio,file=/dev/sdb -vga qxl -vnc 127.0.0.1:0 -daemonize -cdrom /dev/debian-amd64-netinst-3cx.iso -boot once=d

For v20

qemu-system-x86_64 -netdev type=user,id=mynet0 -device virtio-net-pci,netdev=mynet0 -m 1024 -enable-kvm -drive index=0,media=disk,if=virtio,file=/dev/sdb -vga qxl -vnc 127.0.0.1:0 -daemonize -cdrom /dev/debian-amd64-netinst-3cx.iso -boot once=d

Note: Any trouble with QEMU then kill it off and start it again.

pkill qemu

Connect to KVM with VNC Viewer​

Once logged in, connect to the machine with VNC Viewer using localhost:5900 as the address.

Run through the set up​

You may get disconnected off the VNC, just connect back up again and run through set up.



The server will reboot and the VNC will get disconnected. Give it a few minutes and connect back up with VNC.

If you cannot get connected with VNC then reboot the VPS in normal mode and continue the set up via OVH KVM (typically happens with v20 on LE VPS)


Once to get to here, select option 1 and reboot the VPS in to normal mode.






Finish off set up.

Thanks for this update.
it would be very interesting to have the procedure to install on a VPS Limited Edition AMD for v18, since this VPS has a very low price for a server with 2vCore, since it is the minimum that 3CX needs to upgrade to 20.

bruh cmon I cant do all

Just run through the same commands but download the v18 ISO instead and run QEMU with the v18 ISO.

take the commands from the v18 link.

ups but. following these steps, with a vps limited edition AMD, I get the same result: any idea?
thanks a lot.

what OS and distro did you deploy?

 

[Samic]

Youre gonna have to show me what you're doing from the start cos i'm having no issues.

 

[Samic]

I'll give you screenshots of each step:

Redeploy your VPS and start from the beginning.

Yes, don't worry, this VPS no longer exists.

From everything i've read, users have resolved it by recreating the VM.

This works on a new limited VPS for me, but you have to delete the old one (and throw money away).
"Reinstall my VPS" is not enough to get this solved.

At least you got there in the end

Sorry for the stupid question, but if I deploy 3CX on the limited edition VPS using command lines it should work right?

Please, if you succeed, indicate the procedure here, since I have not succeeded.

Hello @xantip, I am a co-worker of Samic. We have acquired a new limited edition VPS in another region, but following the steps of the tutorial that @kieferschild shares, we get the same result. When we connect to QEMU via ultra VNC, we only see the message: “Guest has not initialized the display (yet).” If you have managed to install the ISO, could you detail the steps or which Linux distribution you use or if the QEMU command is different. Thank you very much!
