Was

Raspi, dass werte mit Python abholt und via Apache2 und php anzeigt. Webseite mit einem Argotunnel ins www stellen.

PythonScript holt stündlich den Messwert vom Messgerät und speichert ihn mit einem UnixTimestamp in das /var/www/html/data.txt (1616127492,22178). Es werden nicht mehr als 23 Datensätze gepeichert.
Ein anderes PythonScript holt den Messwert alle 10 sek vom Messgerät und überschreibt ihn mit einem UnixTimestamp in das /var/www/html/dataact.txt (1616124562,15178)
Auf dem Webserver läuft ein php Script das die Daten aus den Files ausliest und darstellt.
Der Argotunnel von Cloudflare leitet die Webseite ins www.

Argo Tunnel

Tunnel erstellen

Instal Argo:

wget -q https://github.com/cloudflare/cloudflared/releases/latest/download/cloudflared-linux-arm64.deb && dpkg -i cloudflared-linux-arm64.deb

Stop the old cloudflared Tunnel

sudo systemctl stop cloudflared

Create a Tunnel:

cloudflared tunnel create <TUNNEL-NAME>

Route traffic to your tunnel to create routes that your tunnel will serve.

cloudflared tunnel route dns <TUNNEL-NAME> tunnel.example.com

anschliessend config erstellen

Config

/etc/cloudflared/config.yml

url: http://localhost:80
tunnel: <Tunnel-UUID>
credentials-file: /root/.cloudflared/<Tunnel-UUID>.json

Service File

/etc/systemd/system/cloudflared.service

[Unit]
Description=Argo Tunnel (%I)
After=network.target

[Service]
TimeoutStartSec=0
Type=notify
ExecStart=/usr/local/bin/cloudflared --autoupdate-freq 24h --config /etc/cloudflared/config.yml tunnel run
Restart=on-failure
RestartSec=5s

[Install]
WantedBy=multi-user.target

Start the Service. Thats it

sudo systemctl start cloudflared

Statische IP

check IP

ip adr

Config anpassen in

sudo nano /etc/netplan/50-cloudcfg.yaml

alles raus und folgendes rein:

network:
  version: 2
  renderer: networkd
  ethernets:
    eth0:
      dhcp4: no
      addresses: [192.168.182./24]
      gateway4: 192.168.182.1
      nameservers:
        addresses: [192.168.182.1,1.1.1.1]

nun

sudo netplan apply

oder reboot

ip check:
