Kaltura CE cannot run when the Security-Enhanced Linux (SELinux) feature is deployed and enabled. If the SELinux feature is deployed on your server, you must disable it to use Kaltura CE.
Within the /etc/sysconfig/selinux file (if exists on your server) set:
SELINUX=disabled

Your server should be restarted after this adjustment is made.

Domain name/virtual host name set within HOSTS file. (Can be done before/after installation)

The domain name (or virtual hostname) you use for the Kaltura CE installation should be set within the /etc/hosts file as follows:

You are directed to make this change at the end of the installation script.
This entry is required so that Kaltura internal API client applications (For example, the Admin Console application and the Kaltura Batch Application) can be directed to the relevant Kaltura web services according to their internal 'server url' configuration.
