2. set the etl user

   cd /home/
   sudo chown etl:etl etl

Disable SELinux (When needed)

Kaltura CE cannot run when the Security-Enhanced Linux (SELinux) feature is deployed and enables. To disable this feature open the /etc/sysconfig/selinux file (if exists on your server), set the following line:

and reboot your server

Installing the xymon package for system monitoring (optional)

Kaltura provides an out-of-the-box monitoring dashboard within the Administration Console, based on xymon (formerly named hobbit) open source technology. This is an optional setup, and you can install and set this configure this add-on after the installation of the Kaltura platform. Installation of the Xymon monitoring system is OS depended.

For installing Xymon on Ubuntu 10.04, please follow these instructions:

For installing Xymon on CentOs5.5, please follow these instructions:

1. Install the xymon package

   apt-get install xymon

2. Set xymon's virtual host

   for setting Xymon’s virtual host. Open the /opt/lampp/etc/httpd.conf file for editing and add the following line after the XAMPP include

   Include /etc/apache2/conf.d/hobbit

3. Set xymon's server security (optional)

   for setting Xymon server security, open the /etc/apache2/conf.d/hobbit file for editing and adjust the following security related lines:
   Change every appearance of this line:

   Allow from localhost ::1/128

   to:

   Allow from all

   Alternatively, you can set access to monitoring pages from your internal network only.
   In addition, add the following lines (keep as 2 lines) before the last the last tag

   Allow from 127.0.0.1
       Satisfy Any

4. Reload apache

   /opt/lampp/lampp reload

5. Set xymon's client configuration

   Edit Xymon client configuration to point to the Xymon server (with single server deployment this can be set to localhost). Open the /etc/default/hobbit-client file for editing and verify that the xymon server is defined correctly.

   HOBBITSERVERS="127.0.0.1"

6. Restart Xymon server and client (single server deployment)

   /etc/init.d/hobbit restart

7. Set the xymon service URL in the Kaltura admin console configuration

   If you install the Xymon service after you already completed your Kaltura CE installation, you should add the Xymon service URL to the Kaltura admin console configuration (this is set automatically during the installation process of the Kaltura CE). Open the YOUR_KALTURA_APPLICATION_BASE_DIR/app/admin_console/configs/application.ini file within your already installed Kaltura CE
   And adjust the the Xymon URL settings

   Settings.xymonUrl = http://YOUR_DOMAIN_NAME/hobbit/

   For information on further configuration and setting up the Xymon alerts, please refer to the Xymon project documentation available within xymon’s help menu documentation

Define domain name/virtual host name within your HOSTS file

The public domain name/virtual hostname to be used for Kaltura CE service should be set within the /etc/hosts file. This is needed so external and internal API client applications e.g. the admin console application, the kaltura batch application) can be directed to the relevant Kaltura web services according to their internal 'server url' configuration. service url configurations are set within Kaltura's internal API client applications, during the installation of the Kaltura CE, based on user input. this step can be done before/after installation
