### Changing Apache configurations post install.
Sometimes, you may want to change deployment settings post installation, for example: replacing the domain, port or protocol, or changing the system to use SSL or stop using SSL.
You can run `/opt/kaltura/bin/kaltura-front-config.sh` as many times as you'd like with different values. The script will re-configure the system accordingly.
For instance, you may want to change the service URL, port or protocol.
