Step-by-step Installation

Pre-Install notes

  • This install guides assumes that you did a clean, basic install of one of the deb based OSes in 64bit architecture.
  • When installing, you will be prompted for each server's resolvable hostname. Note that it is crucial that all host names will be resolvable by other servers in the cluster (and outside the cluster for front machines). Before installing, verify that your /etc/hosts file is properly configured and that all Kaltura server hostnames are resolvable in your network.
  • Before you begin, make sure you're logged in as the system root. Root access is required to install Kaltura, and you should execute sudo -i or su -to make sure that you are indeed root.

Firewall requirements

Kaltura requires certain ports to be open for proper operation. See the list of required open ports. If you're just testing and don't mind an open system, you can use the below to disbale iptables altogether:

iptables -F
service iptables stop
chkconfig iptables off

Disable SELinux - REQUIRED

Currently Kaltura doesn't properly support running with SELinux, things will break if you don't set it to permissive.

setenforce permissive

To verify SELinux will not revert to enabled next restart:

  1. Edit the file /etc/selinux/config
  2. Verify or change the value of SELINUX to permissive: SELINUX=permissive
  3. Save the file /etc/selinux/config

Start of Kaltura installation

This section is a step-by-step guide of a Kaltura installation.

Setup the Kaltura deb repository

wget -O - http://installrepo.kaltura.org/repo/apt/debian/kaltura-deb.gpg.key|apt-key add -
echo "deb [arch=amd64] http://installrepo.kaltura.org/repo/apt/debian jupiter main" > /etc/apt/sources.list.d/kaltura.list

Ubuntu NOTE: You must also make sure the multiverse repo is enabled in /etc/apt/sources.list

Debian Jessie [8] NOTE: You must also make sure the following are enabled in /etc/apt/sources.list

deb htp://ftp.debian.org/debian/ wheezy main
deb htp://security.debian.org/ wheezy/updates main

IMPORTANT NOTE:

depending on your current Apache configuration, you may need to disable your default site configuration.

Use:

# apachectl -t -DDUMP_VHOSTS

to check your current configuration and:

a2dissite $SITENAME

to disable any site that might be set in a way by which $YOUR_SERVICE_URL/api_v3 will reach it instead of the Kaltura vhost config.

In such case, the postinst script for kaltrua-db will fail, if so, adjust it and run:

# dpkg-reconfigure kaltura-db

MySQL Install and Configuration

Please note that for MySQL version 5.5 and above, you must first disable strict mode enforcement. See: https://support.realtyna.com/index.php?/Knowledgebase/Article/View/535/0/how-can-i-turn-off-mysql-strict-mode

Install Kaltura Server

You can use this process to auto install an all in 1 server. In order to perform a manual step by step install, simply copy the commands and run them one by one.

NOTE: the script calls aptitude with -y which means you will not be prompted to confirm the packages about to be installed.

# wget http://installrepo.kaltura.org/repo/apt/debian/install_kaltura_all_in_1.sh 
# chmod +x install_kaltura_all_in_1.sh
# ./install_kaltura_all_in_1.sh

Configure Red5 server

  1. install the kaltura-red5 package:
# aptitude install kaltura-red5
  1. Request http://hostname:5080
  2. Click 'Install a ready-made application'
  3. Mark 'OFLA Demo' and click 'Install'
  4. Edit /usr/lib/red5/webapps/oflaDemo/index.html and replace 'localhost' with your actual Red5 hostname or IP
  5. Test OflaDemo by making a request to http://hostname:5080/oflaDemo/ and playing the sample videos
  6. Run:
/opt/kaltura/bin/kaltura-red5-config.sh

Your Kaltura installation is now complete.

SSL Step-by-step Installation

Pre-Install notes

  • Currently, the Nginx VOD module does not support integration with Kaltura over HTTPs, only HTTP is supported.

SSL Certificate Configuration

Your Kaltura installation is now complete.

Upgrade Kaltura

This will only work if the initial install was using this packages based install, it will not work for old Kaltura deployments using the PHP installers

# aptitude update
# aptitude install ~Nkaltura
# dpkg-reconfigure kaltura-batch
# dpkg-reconfigure kaltura-front

Remove Kaltura

Use this in cases where you want to clear the database and start from fresh.

# /opt/kaltura/bin/kaltura-drop-db.sh
# aptitude purge ~Nkaltura
# rm -rf /opt/kaltura

Troubleshooting

Once the configuration phase is done, you may wish to run the sanity tests, for that, run:

/opt/kaltura/bin/kaltura-sanity.sh

If you experience unknown, unwanted or erroneous behaviour, the logs are a greta place to start, to get a quick view into errors and warning run:

kaltlog

If this does not give enough information, increase logging verbosity:

sed -i 's@^writers.\(.*\).filters.priority.priority\s*=\s*7@writers.\1.filters.priority.priority=4@g' /opt/kaltura/app/configurations/logger.ini

To revert this logging verbosity run:

sed -i 's@^writers.\(.*\).filters.priority.priority\s*=\s*4@writers.\1.filters.priority.priority=7@g' /opt/kaltura/app/configurations/logger.ini

Or output all logged information to a file for analysis:

allkaltlog > /path/to/mylogfile.log
