How do I set up wildcard *DOMAIN* on my droplet?

Question

I’m working on a webapp where users can connect their profile to their domains, but how do I enable wildcard dns in digitalocean? Using vhosts or from the domain panel? Eg: If the user profile is https://webapp.com/user It will be shown on https://user.com/ once the user connects the domain.

I’m using

PHP
Apache
Ubuntu
MySQL

@Cybil Here is the approach I would take: Update DNS to direct all subdomain requests to your Droplet Add your domain webapp.com without any subdomains to the DO Control Panel. add root domain Add an A Record entry to DNS where an asterisk * is the host name and your droplet is selected as the target so that all subdomains route Add * wildcard A-Record Now the DNS record is directing all subdomain URL requests (user1.webapp.com, user2.webapp.com) to your Droplet. To ensure the root domain is also pointing to webapp.com , add an @ A-Record too. Note: From our documentation: (Use) A wildcard (*). To direct requests for a non-existent subdomain to a server or load balancer, enter *. However, if any kind of DNS record exists for a hostname, the wildcard will not apply; you will need to explicitly create an A record for it.https://www.digitalocean.com/docs/networking/dns/how-to/manage-records/#a-records Update Apache config on Droplet to map all subdomains to the right webapp route Enable the mod_vhost_alias extension on Apache with sudo a2enmod vhost_alias and then restart Apache with systemctl restart apache2 Update your Apache config to add a VirtualHost block that maps subdomains to the proper PHP route # ROOT DOMAIN CONFIG ServerName webapp.com DocumentRoot /path/to/webapp #DYNAMIC SUBDOMAIN CONFIG ServerAlias *.webapp.com VirtualDocumentRoot /path/to/webapp/users/%1.php Lastly restart apache again with systemctl restart apache2

Hi, Maybe you want to say https://users.webapp.com ? Your question is to add subdomains for every user and enable https access? Maybe you can turn to acme.sh and it will redirect to a GitHub repo with more information on setting up https. At there you can find what you want. As for wildcard subdomains, just add *.webapp.com in your DNS console. That means, * is the record, and YOUR SERVER IP is the value. Regards,Shiroka
