Question
Can I add a virtual host for subdomain that is hosted by another server?
- Posted April 30, 2021
- Ubuntu 20.04
I followed How To Set Up Apache Virtual Hosts on Ubuntu 18.04 and it is working for two domains, example1.com and example2.com.
Both of them are hosted in a DigitalOcean droplet.
I have another website on Bluehost and I’d like to host its subdomain on the DO droplet. I created a DNS record newsletter.example3.com and www.newsletter.example3.com with my DigitalOcean IP address.
I created newsletter.example3.com.conf:
<VirtualHost *:80>
ServerAdmin my.name@gmail.com
ServerName newsletter.example3.com
ServerAlias www.newsletter.example3.com
DocumentRoot /var/www/newsletter.example3.com/public_html
<Directory /var/www/newsletter.example3.com/public_html>
Options Indexes FollowSymLinks
AllowOverride All
Require all granted
</Directory>
ErrorLog ${APACHE_LOG_DIR}/error.log
CustomLog ${APACHE_LOG_DIR}/access.log combined
<IfModule mod_dir.c>
DirectoryIndex index.php index.pl index.cgi index.html index.xhtml index.htm
</IfModule>
RewriteEngine on
RewriteCond %{SERVER_NAME} =www.newsletter.example3.com [OR]
RewriteCond %{SERVER_NAME} =newsletter.example3.com
RewriteRule ^ https://%{SERVER_NAME}%{REQUEST_URI} [END,NE,R=permanent]
</VirtualHost>
I run sudo a2ensite newsletter.cecilieo.com and restarted apache.
sudo systemctl restart apache2
Problem 1: When I go to newsletter.example3.com, it shows example1.com.
Problem 2: When I run certbot, it returns errors:
sudo certbot --apache -d newsletter.cecilieo.com -d www.newsletter.example3.com

you have an up-to-date TLS configuration that allows the server to
communicate with the Certbot client.

Ok, I solved it. I run
$ sudo certbot --apache -d ....for with/without www. Then it is working. Oh, dear. Thank you for the help.Hi @okadashinichi2819,
Yes, you can add the subdomain as long as it’s pointed to your Droplet.
I think your issue is coming from the DNS propagation. Remember that DNS changes can take up to 24 hours to fully propagate.
Everything else seems to be alright, the configuration file looks good!
