WebSocket reverse proxy with Apache 2.4

To allow access to my local smartMeterLogger I setup a virtual host energie.wasietsmet.nl.

This means setting up a reverse proxy for the websocket running on the smartMeterLogger.
First thing to do is to enable proxy_wstunnel with a2enmod.
Then set up the virtual host. See below how to.
Don’t forget to reload the settings in Apache2!

<VirtualHost *:80>
ServerName energie.wasietsmet.nl

  ProxyRequests Off
 
  ProxyPreserveHost On
 
  ProxyPass / "http://192.168.0.107/"
  ProxyPassReverse / "http://192.168.0.107/"
        
  RewriteEngine on
  RewriteCond %{HTTP:UPGRADE} ^WebSocket$ [NC]
  RewriteCond %{HTTP:CONNECTION} ^Upgrade$ [NC]
  RewriteRule .* ws://192.168.0.107%{REQUEST_URI} [P]

SetEnvIf Request_URI "^/events" dontlog
SetEnvIf Request_URI "^/raw" dontlog

</VirtualHost>

Install Pi-hole on Volumio.

  • Install Volumio the normal way.
  • Set Volumio to accept ssh connections in the developer settings.
  • Open a ssh session to volumio.local and run the Pi-hole install script.
  • Open /etc/lighttpd/lighttpd.conf and set these values:
    server.port = 8080
    server.errorlog = "/tmp/lighttpd_error.log"
    accesslog.filename = "/tmp/lighttpd_access.log"
  • Reload the lighttpd settings with sudo service lighttpd reload or reboot the Raspberry Pi.
  • Go to the Pi-hole web interface at http://volumio.local:8080/admin/
  • (Optional) Set a default web page at the web root:
    cd /var/www/html/
    cp index.lighttpd.orig index.html

    Or set your own index page.

And while you are at it, stop the dhcp-daemon and delete the secondary IP address.

Add password to Apache2 directory.

Put something like this in your sitename.conf:

<IfModule mod_ssl.c>
<VirtualHost *:443>
ServerName muziek.wasietsmet.nl
DocumentRoot "/mnt/music"

<Directory "/mnt/music">
  Allow from all
  AuthUserFile /var/www/muziek.wasietsmet.nl/.wachtwoord
  AuthType Basic
  AuthName "muziek"
  Require valid-user
</Directory>

CustomLog "|/usr/bin/rotatelogs /var/www/muziek.wasietsmet.nl/log/access%d-%m-%Y 86400" vhost_combined env=!dontlog
ErrorLog "|/usr/bin/rotatelogs /var/www/muziek.wasietsmet.nl/log/error%d-%m-%Y 86400"

SSLCertificateFile
...

</IfModule>

Use htpasswd -c /var/www/muziek.wasietsmet.nl/.wachtwoord $USERNAME to create the .wachtwoord file.
