We have a dedicated server with GoDaddy running Plesk that requires SSL.

I've generated the certificate files and I created a vhost_ssl.conf (since I can't edit the default plesk apache configuration http.include, vhost_ssl.conf gets Included to httpd.include) that tells apache where to find the certificate files:

SSLCertificateFile /usr/local/psa/var/certificates/domain.com.crt
SSLCertificateKeyFile /usr/local/psa/var/certificates/domain.com.key
SSLCertificateChainFile /usr/local/psa/var/certificates/sub.class1.server.ca.pem

When I stop/start apache, it refuses to start up. The error_log does not have anything on it either (which is strange).

Then I opened up httpd.include and found this bit:

<VirtualHost 208.xxx.xxx.xxx:443>
    ServerName   domain.com:443
    ServerAlias  www.domain.com
    UseCanonicalName Off

    SSLEngine on
    SSLVerifyClient none
    SSLCertificateFile /usr/local/psa/var/certificates/certagC9054

    Include /var/www/vhosts/domain.com/conf/vhost_ssl.conf

Then I commented out

   SSLCertificateFile /usr/local/psa/var/certificates/certagC9054

(which is plesk's SSL certificate) and restarted apache and it worked perfectly fine.

It seems that Apache does not like multiple SSLCertificateFile within the same VirtualHost directive?

As anyone who worked with plesk knows, I can't just remove SSLCertificateFile directive in httpd.include as plesk will overwrite my changes when someone uses it - which is why it's in vhost_ssl.conf.

So I'm stuck and this is beyond my meager admin skills. Would appreciate someone who knows what (s)he's doing to tell me whats going on.

Thanks in advance.
