This setup installs Collabora onto the same host at Nextcloud.

This setup is used in preference to Nextcloud's built-in Collabora CODE server.

Settings

These settings disable the built-in TLS service but enable TLS termination via a proxy.

The server listens only on the loopback adapter at 127.0.0.1

It's important to set an admin username and password in order to access the console.

coolconfig set ssl.enable false
coolconfig set ssl.termination true
coolconfig set net.proto IPv4
coolconfig set net.listen loopback
coolconfig set storage.wopi.host nextcloud.example.com
coolconfig set server_name nextcloud.example.com:8443
coolconfig set remote_font_config.url https://nextcloud.example.com/index.php/apps/richdocuments/settings/fonts.json
coolconfig set-admin-password --user=admin --password=changeme

Proxy

Proxy port 8443 to 9980 using Reverse proxy settings in Apache2 config (SSL termination).

Use the SSL cert for the nextcloud.example.com site.

NB Port 8443 should be accessible from the internet and the choice of port is arbitrary.

Restart

systemctl start coolwsd

https://nextcloud.example.com:8443/browser/dist/admin/admin.html

https://nextcloud.example.com:8443/hosting/discovery

Use your own server:

https://nextcloud.example.com:8443
