Apache VirtualHost多域多个SSL

Question

Hi I have the following use case, I have an application (let's call it foobar) on a remote server /var/www/foobar and I have the following Apache VirtualHost conf

<VirtualHost *:80>
  DocumentRoot /var/www
  # This is to redirect http traffic to https
  Redirect permanent / https://example.com/
</VirtualHost>

<VirtualHost *:443>
  SSLEngine On
  SSLCertificateFile /etc/ssl/certs/example.com.crt
  SSLCertificateKeyFile /etc/ssl/private/example.com.key
  SSLCertificateChainFile /etc/ssl/certs/example.com.bundle.crt

  ServerName example.com:443
  DocumentRoot /var/www/foobar
</VirtualHost>

And its working all fine. Now suppose I have another domain example2.com and I want it to point to the same foobar application. My current thinking is create another VirtualHost below, something like this

<VirtualHost *:443>
  SSLEngine On
  SSLCertificateFile /etc/ssl/certs/example2.com.crt
  SSLCertificateKeyFile /etc/ssl/private/example2.com.key
  SSLCertificateChainFile /etc/ssl/certs/example2.com.bundle.crt

  ServerName example2.com:443
  DocumentRoot /var/www/foobar
</VirtualHost>

But I was wondering is this the correct way of doing stuff like this? I need both domains to be "independent" so I didn't make a permanent redirect from example2.com to example.com

You can do something like below,You can use the server alias for this, Also I don't see anything wrong in having 2 virtual hosts as well.

<VirtualHost *:443>
    ServerName example1.com
    ServerAlias example2.com
    SSLEngine on
    SSLCertificateFile  /etc/apache2/ssl/apache.crt
    SSLCertificateKeyFile /etc/apache2/ssl/apache.key

    ServerAdmin webmaster@localhost
    DocumentRoot /var/www/html/testlink

</VirtualHost>

If you are getting unable to get a certificate error, you can create a certificate with a wildcard CN. eg : *.com this will match both example1.com and example2.com.
