page	Apache Configuration	Configure Apache to work with home assistant as a subdomain	2016-06-20 13:05	true	false	true	true	Infrastructure

This is an example about how you can configure Apache to act as a proxy for home assistant.

This is useful if you want to have:

• a subdomain redirecting to your home assistant instance
• several subdomain for several instance
• HTTPS redirection

{% linkable_title Subdomain %}

So you already have a working Apache server available at example.org. Your home assistant is correctly working on this web server and available at localhost:8123

To be able to access to your home assistant instance by using https://home.example.org, add to following file into /etc/httpd/conf/extra/hass.conf

<VirtualHost *:443>
  ProxyPreserveHost On
  ProxyRequests Off
  ServerName home.example.org
  ProxyPass / http://localhost:8123/
  ProxyPassReverse / http://localhost:8123/
</VirtualHost>

and make sure that this file is read by apache's main configiuration file /etc/httpd/conf/httpd.conf

...
Include conf/extra/hass.conf
...

If you don't want HTTPS, you can change <VirtualHost *:443> to <VirtualHost *:80> or better consider redirecting all HTTP to HTTPS.

{% linkable_title Multiple Instance %}

You already have home assistant running on localhost:8123 and available at home.example.org as describe before. The configuration file for this home assistant is available in /home/alice/.homeassistant/configuration.yaml

You want another instance available at https://countryside.example.org

You can either :

• Create a new user, bob, to hold the configuration file in /home/bob/.homeassistant/configuration.yaml and run home assistant as this new user
• Create another configuration directory in /home/alice/.homeassistan2/configuration.yaml and run home assistant using hass --config /home/alice/.homeassistant2/

In both solution, change port number used by modifying configuration.yaml

http:
  server_port: 8124
  ...

Start home assistant: Now, you have another instance running on localhost:8124

To access this instance by using https://countryside.example.org add to /etc/httpd/conf/extra/hass.conf

<VirtualHost *:443>
  ProxyPreserveHost On
  ProxyRequests Off
  ServerName countryside.example.org
  ProxyPass / http://localhost:8124/
  ProxyPassReverse / http://localhost:8124/
</VirtualHost>

{% linkable_title HTTP to HTTPS redirection %}

Add to your /etc/httpd/conf/extra/hass.conf

<VirtualHost *:80>
  ServerName example.org
  ServerSignature Off

  RewriteEngine on
  RewriteCond %{HTTPS} !=on
  RewriteRule .* https://%{SERVER_NAME}%{REQUEST_URI} [NE,R,L]
</VirtualHost>
