This example demonstrates 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 subdomains for several instances
- HTTPS redirection
Subdomain
So you already have a working Apache server available at example.org. Your Home Assistant is correctly working on this webserver and available at http://localhost:8123
Enable mod_proxy_wstunnel by running if you encounter issues while serving Home Assistant through your proxy:
sudo a2enmod proxy_wstunnel
To be able to access to your Home Assistant instance by using https://home.example.org, add the following file to /etc/httpd/conf/extra/ as hass.conf
<VirtualHost *:443>
ServerName home.example.org
ProxyPreserveHost On
ProxyRequests off
ProxyPass /api/websocket ws://localhost:8123/api/websocket
ProxyPassReverse /api/websocket ws://localhost:8123/api/websocket
ProxyPass / http://localhost:8123/
ProxyPassReverse / http://localhost:8123/
RewriteEngine on
RewriteCond %{HTTP:Upgrade} =websocket [NC]
RewriteRule /(.*) ws://localhost:8123/$1 [P,L]
RewriteCond %{HTTP:Upgrade} !=websocket [NC]
RewriteRule /(.*) http://localhost:8123/$1 [P,L]
</VirtualHost>
and make sure that this file is read by Apache’s main configuration 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.
<VirtualHost *:443>
[...]
ProxyPass /api/websocket ws://localhost:8123/api/websocket disablereuse=on
[...]
ProxyPass / http://localhost:8123/ disablereuse=on
[...]
</VirtualHost>
Multiple Instance
You already have Home Assistant running on http://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.yamland run Home Assistant as this new user - Create another configuration directory in
/home/alice/.homeassistan2/configuration.yamland run Home Assistant usinghass --config /home/alice/.homeassistant2/
In both solution, change the port number used by modifying configuration.yaml
http:
server_port: 8124
...
Start Home Assistant: Now, you have another instance running on http://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 /api/websocket ws://localhost:8123/api/websocket
ProxyPassReverse /api/websocket ws://localhost:8123/api/websocket
ProxyPass / http://localhost:8124/
ProxyPassReverse / http://localhost:8124/
</VirtualHost>
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>
