This worked for Debian 8 (Jessie)
replace original /etc/sources.list with:
deb http://archive.debian.org/debian/ jessie main non-free contrib deb-src http://archive.debian.org/debian/ jessie main non-free contrib deb http://archive.debian.org/debian-security/ jessie/updates main non-free contrib deb-src http://archive.debian.org/debian-security/ jessie/updates main non-free contribapt-update
It will give a keyring error. I tried both:
Install a standard Debian Bookworm, for details consider the Debian installation guide, and configure a static IP.
Note: The Debian installer performs network configuration by IPv6 autoconfiguration and DHCP by default, if available. To force manual network configuration in the UEFI installer, press E and add netcfg/disable_autoconfig=true to the linux command line. For the BIOS installer, select the Help entry and start the installation by typing installgui netcfg/disable_autoconfig=true. For further details, see the Debian installer documentation.
It is recommended to only install the “standard system utilities” and “SSH server” package selection, as Proxmox VE brings its own packages for QEMU and LXC. A desktop environment is not necessary.
Add an /etc/hosts entry for your IP address
The hostname of your machine must be resolvable via /etc/hosts. This means that in /etc/hosts you need one of the following entries for your hostname:
Log into the Debian/Ubuntu device
Run the following commands in a terminal:# update repositories and install any available software updates
sudo apt update sudo apt upgrade # install Apache HTTPD sudo apt install apache2 # install PHP components sudo apt install php7.3 php7.3-xml # download phpSysInfo wget https://github.com/phpsysinfo/phpsysinfo/archive/v3.3.2.zip # extract v3.3.2.zip sudo unzip v3.3.2.zip -d /var/www/html # rename the extracted folder sudo mv /var/www/html/phpsysinfo-3.3.2 /var/www/html/phpsysinfo # make a copy of phpsysinfo.ini sudo cp /var/www/html/phpsysinfo/phpsysinfo.ini.new /var/www/html/phpsysinfo/phpsysinfo.ini # set the owner of the new phpsysinfo directory to www-data sudo chown -R www-data:www-data /var/www/html/phpsysinfo sudo systemctl restart apache2
Open a web browser and navigate to http://DNSorIP/phpsysinfo
This article is inspired and prepared on the forked Cloudmin Xen script updated for Debian 10. However, the following procedures to be followed as precuationary before executing the updated script, which is available in this post in below section.
PHASE-I Prepare Environment for XEN
INSTALLING THE XEN HYPERVISOR AND HOST/CONTROL DOMAIN (“DOM0”)
In this step we install the Xen Project hypervisor software package, and configure the Dom0 virtual machine by way of the Debian base operating system. Once all preliminary configuration is complete, we will reboot the computer and automatically boot into the Xen hypervisor/Dom0 virtual machine to explore the new system.
INSTALL XEN HYPERVISOR
If you need to add a non-root user, the sudo package, non-free firmware, a firewall, or other necessary packages, now is the time.
Use apt-get to update the Debian base operating system package index files, and upgrade all currently installed packages. As root (or using sudo) run the following command:
# apt-get update && apt-get upgrade
Next, use apt-get to install the Xen Project hypervisor meta-package. Run the following command as root, adjusting the architecture suffix to suit your hardware:
First, update all the packages of the system by below-mentioned command:
sudo apt update
After updating packages, now install the dependencies required by the below-mentioned command:
sudo apt install software-properties-common ca-certificates lsb-release apt-transport-https
Enable SURY Repository
The following step is to integrate the SURY repository into our system. SURY is a Debian-based third-party PHP repository that bundles PHP software, run the following command to add SURY repository:
Found this lovely code base (that actually worked) on github, supported on a debian 10/11 or ubuntu 20+ versions-
The script (jitsi_setup.sh) can be used to install stable version of all 3 on a stand-alone server. This is simply a script version of quick-install document at https://jitsi.github.io/handbook/docs/devops-guide/devops-guide-quickstart
It Installs below mentioned software:
nginx, prosody, jitsi-meet-prosody, jitsi-meet, jitsi-meet-web, jitsi-meet-web-config, jitsi-meet-turnserver, jicofo, jitsi-videobridge2
Below are optional, will be installed only if opted for:
jigasi (https://github.com/jitsi/jigasi)
jibri (https://github.com/jitsi/jibri)
Also has option for configuring:
Disable on Centos/RHEL system:
1. Append below lines in /etc/sysctl.conf:
net.ipv6.conf.all.disable_ipv6 = 1 net.ipv6.conf.default.disable_ipv6 = 1
NOTE : To disable IPv6 on a single interface add below lines to /etc/sysctl.conf :
net.ipv6.conf.[interface].disable_ipv6 = 1 ### put interface name here [interface] net.ipv6.conf.default.disable_ipv6 = 1
2. To make the settings affective, execute :
# sysctl -p
Disable on Debian/Ubuntu system:
One method to make this option persist is modifying /etc/sysctl.conf. Add the following lines to the file:
net.ipv6.conf.all.disable_ipv6=1 net.ipv6.conf.default.disable_ipv6=1 net.ipv6.conf.lo.disable_ipv6=1
For the settings to take effect use:
sudo sysctl -p
Well, in my working domain I face these tools to be installed, so that most of the dependent tools or programs that need to be deployed later don’t face much of dependency issue. So here goes the installation process for both the OS.
On CentOS/RHEL system use the follwoing command (either one of it would work)-
Type the following yum command as root user:
# yum group install "Development Tools"
Step 1: Update Debian OS
Ensure your Debian 11 (Bullseye) operating system is upgraded.
sudo apt -y update && sudo apt -y upgrade
Once the upgrade process is complete, reboot the server
sudo systemctl reboot
Step 2: Set Proxmox Server hostname
Let’s set a hostname on the server
sudo hostnamectl set-hostname proxmox7node01.example.com --static
Replaceproxmox7node01.example.com with correct hostname you’re setting on your system. Get the IP address of the primary interface:
To find out the current version of Linux kernel running on your system, use the following command.
$ uname -sr Linux 4.12.0-041200-generic
To list all installed kernels on your system, issue this command.
$ dpkg -l | grep linux-image | awk '{print$2}'
linux-image-4.12.0-041200-generic
linux-image-4.8.0-22-generic
linux-image-extra-4.8.0-22-generic
linux-image-generic
Remove Old Unused Kernels on Debian and Ubuntu
Run the commands below to remove a particular linux-image along with its configuration files, then update grub2 configuration, and lastly reboot the system.
$ sudo apt remove --purge linux-image-4.4.0-21-generic $ sudo update-grub2 $ sudo reboot
