Proxmox Information

  • A Debian- based Linux distribution.
  • The web interface is very easy to set up and manage.
  • Using Qemu virtualization infrastructure images.
  • VirtualBox – from VMware images You can export it .
  • You can use it corporately; you can also pay for and receive the service.
  • You need to use Ethernet, not Wi-Fi. I tried Wi-Fi, but it causes problems with NAT and other things, and it's not supported.
  • If there are multiple Ethernet ports, it is recommended to separate these connections for different purposes such as Proxmox Management, ERP, Domain Server, and Mail Server.

Proxmox Recommended Setup

The HP 24 All-in-One PC we use for our lab can be replicated at home with a powerful laptop or gaming PC.

After Proxmox Installation

Setting up the repository for updates.

Proxmox-> Updates-> Repositories alanına gidiyoruz

Here we select the 2 Repository areas that are labeled Enterprise and disable them.

Sonra buraya Add-> No-Subscription olanı ekliyoruz.

Daha sonra Update için Proxmox->Updates->Upgrades tuşuna basıyoruz.

Remove the warning that appears upon entry/Nap Close

1. Proxmox Shell will be opened.

2.cd /usr/share/javascript/proxmox-widget-tool

3.cp proxmoxlib.js proxmoxlib.js.backup

4.nano proxmoxlib.js

5.CRTL+F    (checked_command)

6.4 Leave a space and add 2 lines;

   orig_cmd()

  return;

This way it will bypass the code,

no warning will be sent

Proxmox BACKUP

Proxmox primarily uses data from 3 different areas. 6 place to backup

We create the following script named pve-backup.sh under /usr/local/bin/.

———————————————————————————-

#PVE-BACKUP SCRIPT

#!/bin/bash

DEST=”/mnt/pve/Backup/proxmox-config”

DATE=$(date +%F)

mkdir -p $DEST

tar czf $DEST/pve-config-$DATE.tar.gz /etc/pve /etc/network /etc/hosts /var/lib/pve-cluster /etc/resolv.conf /etc/network /etc/hostname

find $DEST -type f -mtime +30 -delete

———————————————————————————–

Make it executable:

chmod +x /usr/local/bin/pve-backup.sh

Then add to cron:

crontab -e

0 3 * * * /usr/local/bin/pve-backup.sh

This automatically creates daily configuration backups and deletes older files after 30 days.

Proxmox RECOVER

Proxmox Remote Connection

I used Tailscale for the remote connection.

  • You are creating an account on Tailscale.
  • Install Tailscale agent to the computer you are using.
  • In a Linux environment, you install a package and pair the Proxmox device with your account.
    • ´curl – fsSL https://tailscale.com/install.sh | sh
    • ´sudo tailscale up

And also for the certificate;

Proxmox Close Screen

I am not using Proxmox Host Scrren for management because of that Inwant to close Scrren after one minute. For this;

  • nano /etc/default/grub
  • GRUB_CMDLINE_LINUX_DEFAULT field We're going.
  • GRUB_CMDLINE_LINUX_DEFAULT="quiet consoleblank = 60 " We're setting it . 60 seconds later Screen is closing.
  • Then we are running update-grub for this to be valid.
