Proxmox Configuration

• Guide to install on emmc

1. Tailscale.

Install and authenticate as always. Start with:

tailscale up --ssh --accept-routes --accept-dns=false --advertise-tags=tag:system-tjo-cloud --hostname=$(hostname -f | sed 's/\./-/g')

2. Install intel-firmware updates.

# Add non-free-firmware to the end
vim /etc/apt/sources.list

apt install intel-microcode

reboot

2. Configure Hosts.

Every Proxmox node needs to have configured /etc/hosts with entries for all servers.

Servers

100.71.223.89 naboo.system.tjo.cloud naboo
fd7a:115c:a1e0::8701:df59 naboo.system.tjo.cloud naboo

100.99.13.61 mustafar.system.tjo.cloud mustafar
fd7a:115c:a1e0::2601:d3d mustafar.system.tjo.cloud mustafar

3. Connect to Proxmox Cluster.

The $EXISTING_CLUSTER_NODE_HOST_NAME (examples: nevaroo, jakku not the FQDN) represent an existing cluster node, via which the new node will join to the cluster.

This node's ssh key (cat ~/.ssh/id_rsa.pub) must be added to the $EXISTING_CLUSTER_NODE_HOST_NAME under ~/.ssh/authorized_keys.

Then the node can join the cluster using:

pvecm add $EXISTING_CLUSTER_NODE_HOST_NAME --link0 $(tailscale ip -4) --link1 $(tailscale ip -6)

4. Configure Firewall.

# Disable Web Portal on public IP
iptables -A INPUT -p tcp -i vmbr0 --dport 8006 -j DROP

5. Disable RPC Bind

systemctl disable --now rpcbind.target
systemctl disable --now rpcbind.socket
systemctl disable --now rpcbind.service

5. Disable SSH Access from public internet and enable public key auth.

Make sure to copy your public key using ssh-copy-id root@proxmox.ip.address.

echo "PasswordAuthentication no" >> /etc/ssh/sshd_config

6. Done

Your node should now be visible at https://proxmox.tjo.cloud.
