I wanted to publish another site on my server. Now I have Nginx and WordPress but how to publish another site lets say on address malaczynski.pl/test/?
We will use Nginx web server.
I put all new site files in /var/www/test folder,
now I open Nginx config:
sudo nano /etc/nginx/sites-available/wordpress.confand add before last } :
location /test {
root /var/www;
}Ok, I migrated.
Services that I have transferred:
New site: https://websiteforstudents.com/how-to-install-wordpress-on-ubuntu-linux-with-nginx/
I did everything without a database (I already have one) and Let’s Encrypt (Cloudflare provides me with an SSL certificate). Speaking about Cloudflare, I changed the IPv6 address in their configuration for the new server.
The last thing I did was copy the entire WordPress directory and overlay the old one on the new installation. That was the hardest part, because I didn’t know how to copy data from one VPS to another.
rsync -avzhe 'ssh -p 10XXX' --progress /var/www [email protected]:/var/wwwPerformed on the old server fixed the issue.
I used the instructions from this webpage: https://www.tecmint.com/rsync-local-remote-file-synchronization-commands/
Edit. It wasn’t.
The last thing was to change wp-config.php file to change database name, username, password and host.
From time to time the photo module in MagicMirror hangs. I used to restart it manually by logging into the Raspberry and using the command “pm2 restart mm”. Now I want to make it so that it automatically restarts when I scan the NFC tag stuck to the back of the monitor.
So I divided big problem to smaller ones:
1. Restart MM,
2. Connection HA to MM machine,
3. Automation when HA apk scan tag,
4. Stick the NFC tag to the monitor xD
pm2 restart mm
2. Connection HA to MM mashine
HA needs to let MM know to shut down for a while, so I guess the easiest way to do this is with mqtt broker.
I have used before Mosquitto, so I will use it.
MM site:
I created 2 files in my home directory: restartmm.sh and restartmm.py
restartmm.sh:
#!/usr/bin/env python
sleep 20
python /home/pi/restartmm.py &restartmm.py basen on mqtt-screen-power project:
mqtt_host = "192.168.xxx.xxx"
mqtt_port = 1883
mqtt_topic = "/screen/restart"
mqtt_username = "xxxxxxxx"
mqtt_password = "xxxxxxxx"
power_on_command = "pm2 restart mm"
power_off_command = " "
import paho.mqtt.client as mqtt
import subprocess
def on_connect(client, userdata, flags, rc):
# The callback for when the client receives a CONNACK response from the server.
print("Connected with result code "+str(rc))
# Subscribing in on_connect() means that if we lose the connection and
# reconnect then subscriptions will be renewed.
client.subscribe(mqtt_topic)
def on_message(client, userdata, msg):
# The callback for when a PUBLISH message is received from the server.
print(msg.topic+" "+str(msg.payload))
if str(msg.payload) == "ON":
subprocess.Popen(power_on_command,
shell=True, stdout=subprocess.PIPE)
else:
subprocess.Popen(power_off_command,
shell=True, stdout=subprocess.PIPE)
client = mqtt.Client()
client.on_connect = on_connect
client.on_message = on_message
client.username_pw_set(mqtt_username, mqtt_password)
client.connect(mqtt_host, mqtt_port, 60)
# Blocking call that processes network traffic, dispatches callbacks and
# handles reconnecting.
# Other loop*() functions are available that give a threaded interface and a
# manual interface.
client.loop_forever()Both files chown is 755. Autostart with command “crontab -e” – “@reboot sh /home/XXXXX/restartmm.sh”
HA site:
HA configuration.yaml
switch:
- platform: mqtt
name: "MM restart"
command_topic: "/screen/restart"
automations.yaml:
- alias: turn_off_restart_mm
trigger:
platform: state
entity_id: switch.mm_restart
to: 'on'
for:
seconds: 1
action:
service: switch.turn_off
entity_id: switch.mm_restart3. Automation when HA apk scan tag,
HA automations.yaml:
- alias: mm_tag
initial_state: true
trigger:
- platform: tag
tag_id: 7275ecff-27a1-4c4d-a7fd-69647998dbf8
action:
- service: switch.turn_on
entity_id: switch.mm_restart
4. Stick the NFC tag to the monitor. Formality.
