Question

How to install Webmin on existing Apache + Let's Encrypt SSL configuration?

Using this guide for reference: https://www.digitalocean.com/community/tutorials/how-to-install-webmin-on-ubuntu-18-04

Currently have Apache + Let’s Encrypt SSL configured and working fine, plus a reverse proxy for Discourse in a Docker container. I was able to follow all points of the Webmin installation until I was tasked with obtaining an SSL certificate, which won’t work as I already have one. I tried just skipping that part but Webmin doesn’t appear at mydomain.com:10000 or mydropletip:10000, with or without https in the URL.

My vhost file looks a little different from the guide because of the aforementioned server configuration.

<VirtualHost *:80>
	ServerAdmin mygmail
	ServerName mysite.com
	ProxyPass / http://localhost:10000/
	ProxyPassReverse / http://localhost:10000/
	ServerAlias www.mysite.com
	DocumentRoot /var/www/mysite.com
	ErrorLog ${APACHE_LOG_DIR}/error.log
	CustomLog ${APACHE_LOG_DIR}/access.log combined
RewriteEngine on
RewriteCond %{SERVER_NAME} =mysite.com [OR]
RewriteCond %{SERVER_NAME} =www.mysite.com
RewriteRule ^ https://%{SERVER_NAME}%{REQUEST_URI} [END,NE,R=permanent]
</VirtualHost>

Is there any way I can manually configure what I need for Webmin to work?

Thanks!

Hi @orbitstorm88,

Can you check if WebAdmin is actually running on the said port? You can do that by typing in :

netstat -tulpen | grep 10000

If it’s there, then most probably you’ll need to allow it through your firewall. What firewall are you using, is it ufw or plain iptables?

Additionally, if you try your droplet’s IP + the port does it work?
