Hello.

The issue here is that /etc/init.d/httpd reload fails. Start by looking at /etc/httpd/conf.d/zzzkaltura.ssl.conf and see what it looks like. Should be similar to:
SSLCertificateFile /etc/ssl/certs/rhel7.kaltura.org.crt
SSLCertificateKeyFile /etc/pki/tls/private/rhel7.kaltura.org.key
SSLCACertificateFile /etc/ssl/certs/ca-kaltura.org.crt

SSLEngine on
SSLProtocol all -SSLv2
SSLCipherSuite ALL:!ADH:!EXPORT:!SSLv2:RC4+RSA:+HIGH:+MEDIUM:+LOW

    ErrorLog "/opt/kaltura/log/kaltura_apache_errors_ssl.log"
    CustomLog /opt/kaltura/log/kaltura_apache_access_ssl.log vhost_kalt

    Include "/opt/kaltura/app/configurations/apache/conf.d/enabled.*.conf"

Only with paths to your own certificates and key files and your own host.
This file is auto generated from /opt/kaltura/app/configurations/apache/kaltura.ssl.conf.template when running /opt/kaltura/bin/kaltura-front-config.sh

I recently made a fix in this area so make sure you have:

rpm -q kaltura-postinst

kaltura-postinst-1.0.30-9.noarch
