I'm trying to setup SSL on fedora with apache.

In my vhost...

SSLCertificateFile /your/path/to/crt.crt
SSLCertificateKeyFile /your/path/to/key.key
SSLCertificateChainFile /your/path/to/DigiCertCA.crt

I had it working fine with a self signed key, but can't get it to work with the DigiCertCA crt.

When I run

service httpd restart

It fails to start. This is what I get in the logs...

[Sat Jan 29 07:57:13 2011] [notice] suEXEC mechanism enabled (wrapper: /usr/sbin/suex$
[Sat Jan 29 07:57:13 2011] [error] Failed to configure CA certificate chain!

Any assistance would be really appreciated!

Thanks

Make sure there's no missing certificates in the chain, in the SSLCertificateChainFile file there should be all the certificates in order from the CA first and then down to any intermediate certificate that was used to sign your CRT, otherwise you'll get the error.

If you don't have any intermediate certificates (looking at the Digicert page it looks like there's none http://www.digicert.com/ssl-certificate-installation-apache-ensim.htm) you should use SSLCACertificateFile instead

I don't know who downvoted you, this is entirely valid - the instructions even tell you to use SSLCACertificateFile. –  troyengel Jan 29 '11 at 15:29
    
Thanks. turns out it was just there was an 'X' at the bottom of one of the crt files (that I had accidentally put in the file when pressing ctrl+x to close the file. Answer accepted for just checking the chain properly. –  kron Jan 29 '11 at 15:56
    
If you think you copied and pasted correctly double check for white space. For example copying from the Verisign/Symantec the help page knowledge.verisign.com/support/ssl-certificates-support/… results in two extra spaces on each line. –  Daniel Sokolowski Dec 15 '12 at 5:45

i had similar issue when i copied digicert intermediate certificate while saving the cert i mistakenly entered some characters in the cert file and i couldn't restart apache but when i removed the characters and restarted the server it worked.

The fix above may be useful, but for me the fix was this:

http://blog.oneiroi.co.uk/openssl/x.509/pcks7/openssl-unable-to-load-certificate-wrong-asn1-encoding-routines-asn1-check-tlen-tag-tasn-dec-dot-c-1319/

In case the link goes:

The format in this case is p7b (PCKS #7); to use the certificate witih apache you’re going to have to convert this.

openssl pkcs7 -print_certs -in certificate.p7b -out certificate.cer

Within the resulting .cer file you will file you x.509 certificate bundled with relevant CA certificates, break these out into your relevant .crt and ca.crt files and load as normal into apache.
