Running Nuclos behind a reverse proxy

Run Nuclos behind an Apache reverse proxy – AJP connector and vhost configuration for rich and web client.

Auf dieser Seite

Tomcat can run behind an Apache reverse proxy – e.g. when Nuclos should be served over HTTPS but port 443 is already taken.

Configure Tomcat

The AJP connector must be enabled. Since Nuclos 4.8.0 this is done directly in the installer (step „Server configuration“) – no manual Tomcat change needed.

The AJP protocol is mandatory, otherwise the access path to the Nuclos instance is not mapped correctly.

Apache for the rich client (Java Web Start)

Create a vhost and adjust the domain:

<VirtualHost *:80>
ServerName nuclet.nuclos.de
ServerAlias nuclet.nuclos.de
Redirect 301 / https://nuclet.nuclos.de/
</VirtualHost>

<VirtualHost *:443>
ServerName nuclet.nuclos.de
ServerAlias nuclet.nuclos.de
ProxyRequests Off
SSLEngine on
SSLCertificateKeyFile /etc/apache2/ssl/nuclet.nuclos.de/nuclet.nuclos.de.key
SSLCertificateFile /etc/apache2/ssl/nuclet.nuclos.de/nuclet.nuclos.de.crt
SSLCertificateChainFile /etc/apache2/ssl/nuclet.nuclos.de/Intermediate_CA_Bundle.crt
ErrorDocument 503 "/var/www/maintance.html"
<Proxy *>
    Order deny,allow
    Allow from all
</Proxy>
ProxyPass               /       ajp://localhost:8009/
ProxyPassReverse        /       ajp://localhost:8009/
<Location />
    Order allow,deny
    Allow from all
</Location>
</VirtualHost>

Enable the module and restart Apache:

a2enmod proxy_ajp
service apache2 restart

Apache for the web client

<VirtualHost *:80>
    ServerName www.example.org
    ServerAlias www.example.org
    Redirect 301 / https://www.example.org
</VirtualHost>

<VirtualHost *:443>
    ServerName www.example.org
    ServerAlias www.example.org
    ProxyRequests Off
    SSLEngine on
    SSLCertificateKeyFile /etc/ssl/private/ssl-cert-snakeoil.key
    SSLCertificateFile    /etc/ssl/certs/ssl-cert-snakeoil.pem
    ErrorDocument 503 "/var/www/maintance.html"
    
    <Proxy *>
        Order deny,allow
        Allow from all
    </Proxy>
    ProxyPass               /nuclos-instanzname   ajp://localhost:8010/nuclos-instanzname
    ProxyPassReverse        /nuclos-instanzname   ajp://localhost:8010/nuclos-instanzname
    ProxyPass               /                     ajp://localhost:8010/webclient/
    ProxyPassReverse        /                     ajp://localhost:8010/webclient/
    <Location />
        Order allow,deny
        Allow from all
    </Location>
</VirtualHost>
