Foreman » Installer

facter fqdn and hostname -f both return
HOSTNAME.domain.com

All config files (like httpd) are configured with this hostname in uppercase.

But the puppet cert that is generated is in lowercase.
Resulting in httpd not beeing able to start.

# service httpd start
Starting httpd: [Tue Jun 24 13:26:59 2014] [warn] module passenger_module is already loaded, skipping
Syntax error on line 37 of /etc/httpd/conf.d/25-puppet.conf:
SSLCertificateFile: file '/var/lib/puppet/ssl/certs/HOSTNAME.domain.com.pem' does not exist or is empty
[FAILED]

There is a .pem file generated in /var/lib/puppet/certs/, but it is in lowercase.

I changed my hostname to lowercase, regenerated a cert, and it now works.
But this should be checked (warning) or worked around for easy deployment.
