Install Proxmox VE on Debian Stretch
|Note: Article about the old stable Debian 9 and Proxmox VE 5.x releases, which are both End-of-Life since July 2020.|
NOTE: We recommend using the article for the current stable release: Install Proxmox VE on Debian Buster
The installation of a supported Proxmox VE server should be done via Bare-metal_ISO_Installer. In some case it makes sense to install Proxmox VE on top of a running Debian Stretch 64-bit, especially if you want a custom partition layout. For this HowTO the following Debian Stretch ISO was used: .
Install a standard Debian Stretch (amd64)
Install a standard Debian Stretch, for details see Debian, and select a fixed IP. It is recommended to only install the "standard" package selection and nothing else, as Proxmox VE brings its own packages for qemu, lxc.
Add an /etc/hosts entry for your IP address
Please make sure that your hostname is resolvable via /etc/hosts, i.e you need an entry in /etc/hosts which assigns an IPv4 address to that hostname.
Note: Make sure that no IPv6 address for your hostname is specified in /etc/hosts
For instance if your IP address is 192.168.15.77, and your hostname prox4m1, then your /etc/hosts file should look like:
127.0.0.1 localhost.localdomain localhost 192.168.15.77 prox4m1.proxmox.com prox4m1 # The following lines are desirable for IPv6 capable hosts ::1 localhost ip6-localhost ip6-loopback ff02::1 ip6-allnodes ff02::2 ip6-allrouters
You can test if your setup is ok using the hostname command:
hostname --ip-address 192.168.15.77 # should return here your IP address
Install Proxmox VE
Adapt your sources.list
Add the Proxmox VE repository:
echo "deb http://download.proxmox.com/debian/pve stretch pve-no-subscription" > /etc/apt/sources.list.d/pve-install-repo.list
Add the Proxmox VE repository key:
wget http://download.proxmox.com/debian/proxmox-ve-release-5.x.gpg -O /etc/apt/trusted.gpg.d/proxmox-ve-release-5.x.gpg chmod +r /etc/apt/trusted.gpg.d/proxmox-ve-release-5.x.gpg # optional, if you have a changed default umask
Update your repository and system by running:
apt update && apt dist-upgrade
NOTE: If you have enabled other another arch (typically, i386 to run some older software) and apt complains about not being able to find /binary-i386: "Unable to find expected entry 'pve/binary-i386/Packages'" you need to remove other arch or use instead the row:
deb [arch=amd64] http://download.proxmox.com/debian/pve stretch pve-no-subscription
this is because Proxmox repository does not have any other arch besides amd64; more info on multiarch on debian on: https://wiki.debian.org/Multiarch/HOWTO.
Install Proxmox VE packages
Install the Proxmox VE packages
apt install proxmox-ve postfix open-iscsi
Accept the suggestion to remove Exim and configure postfix according to your network. If you have a mail server in your network, you should configure postfix as a satellite system, and your existing mail server will be the 'relay host' which will route the emails send by the proxmox server to the end recipient. If you don't know what to enter here, choose local only.
Finally, reboot your system, the new Proxmox VE kernel should be automatically selected in the GRUB menu.
Note: If you have a subscription key don't forget to switch to the enterprise repository after installation, see Package repositories.
Recommended: remove the os-prober package
The os-prober package scans all the partitions of your host including those of you guests VMs to create dual-boot GRUB entries. If you didn't install Proxmox VE as a dual boot besides another Operating System you can safely remove the os-prober package.
apt remove os-prober
Connect to the Proxmox VE web interface
Connect to the admin web interface (https://youripaddress:8006). If you have a fresh install and didn't add any users yet, you should use the root account with your linux root password, and select "PAM Authentication" to log in.
Once logged in, create a Linux Bridge called vmbr0, and add your first network interface to it.
Configure apt to use the new packages repositories
In order to get latest updates, you need to add one of the new package repositories, see Package repositories
resolv.conf gets overwritten
The PVE GUI expects to control DNS management and will no longer take its DNS settings from /etc/network/interfaces Any package that auto-generates (overwrites) /etc/resolv.conf will cause DNS to fail. e.g. packages 'resolvconf' for IPv4 and 'rdnssd' for IPv6.
Optional: Remove the Debian kernel
apt remove linux-image-amd64 linux-image-4.9.0-3-amd64
Check grub2 config by running:
