WebSocket reverse proxy with Apache 2.4

Posted on by

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

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.

Apache2 proxy setup.

Om lan servers via internet te benaderen en daarbij niet te veel poorten te hoeven openen kun je Apache2 gebruiken als proxy server.

Voorbeeld salamanders:

Opslaan als salamanders.wasietsmet.nl.conf in /etc/apache2/sites-available.

<VirtualHost *:80>

    Servername salamanders.wasietsmet.nl

    ProxyRequests Off

    ProxyPreserveHost On

    <Location />
        ProxyPass "http://192.168.0.199/"
        ProxyPassReverse "http://192.168.0.199/"
    </Location>

    SetEnvIf Request_URI "^/api/getdevice" dontlog

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

</VirtualHost>

Nu alleen nog Apache2 op de hoogte stellen:

a2ensite salamanders*
service apache2 reload

En het werkt.
