How to contribute

Pre-Install steps

  • This guide assumes that you have a clean, basic install of one of the RHEL based OS's in 64bit architecture.
  • During the installation process, you will be prompted about several hostnames. Note that it is crucial that all host names will be resolvable by other members of the cluster (and outside the cluster in the case of API/front machines). Before installing, verify that your DNS contains records for all the hostnames you intend to use or that the /etc/hosts file on all machines is properly configured to include them.
  • 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 locally and don't mind an open system, you can use the below to disable iptables altogether:

# iptables -F
# service iptables stop
# chkconfig iptables off

Set SELinux to permissive mode - REQUIRED

Currently Kaltura doesn't properly support running with SELinux in enforcing mode, 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

Setup the Kaltura RPM repository

# rpm -ihv http://installrepo.kaltura.org/releases/kaltura-release.noarch.rpm

Note for RHEL/CentOS 7 users

Depending on what repos you have enabled, you may also need to add the EPEL or CentOS repos to resolve all dependencies.

Installing on AWS EC2 instances

Depending on your setup, you may need to enable two additional repos: rhui-REGION-rhel-server-extras and rhui-REGION-rhel-server-optional. This can be done by editing /etc/yum.repos.d/redhat-rhui.repo and changing:

enabled=0

to:

enabled=1

under the following sections:

rhui-REGION-rhel-server-optional
rhui-REGION-rhel-server-extras

Or by running the following commands:

# yum -y install yum-utils
# yum-config-manager --enable rhui-REGION-rhel-server-extras rhui-REGION-rhel-server-optional

Enabling the EPEL repo

To add the EPEL repo:

# rpm -ihv https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm

MySQL Install and Configuration

For MySQL versions higher 5.5 and above, note that you must disable strict mode for the deployment to succeed. Please see the following document: https://dev.mysql.com/doc/refman/5.5/en/sql-mode.html#sql-mode-setting

RHEL/CentOS 6 setup:

# yum install mysql-server
# service mysqld start
# mysql_secure_installation
# chkconfig mysqld on

RHEL/CentOS 7 setup:

# yum install mariadb-server
# service mariadb start
# mysql_secure_installation
# chkconfig mariadb on

**Make sure to answer YES for all steps in the mysql_secure_install install, and follow through all the mysql install questions before continuing further. Failing to properly run mysql_secure_install will cause the kaltura mysql user to run without proper permissions to access your mysql DB, and require you to start over again.

Mail Server (MTA) Install and Configuration

If your machine doesn't have postfix email configured before the Kaltura install, you will not receive emails from the install system nor publisher account activation mails. If postfix runs without further configuration starting it is sufficient to make Kaltura work.

# service postfix restart

If you are using Amazon Web Services (AWS) please note that by default EC2 machines are blocked from sending email via port 25. For more information see this thread on AWS forums.

Note regarding desktop installations

When installing on a "desktop" environment there may be package conflicts with media encoding/decoding plugins.

In Redhat 6.5 you should run the following to remove the conflicting packages: # rpm -e gstreamer-plugins-bad-free totem totem-nautilus

Non-SSL Step-by-step Installation

Before you can deploy your Kaltura CE Server, you need to perform some preliminary actions such as adding the Kaltura RPM repos, setting SELinux to persmissive mode and deploying MySQL. Please see pre-install steps.

Install the basic Kaltura Packages:

# yum clean all
# yum install kaltura-server

Configure MySQL with the required Kaltura Settings

# /opt/kaltura/bin/kaltura-mysql-settings.sh

Start required service and configure them to run at boot:

# service memcached restart
# service ntpd restart
# chkconfig memcached on
# chkconfig ntpd on

Start of Kaltura Configuration

# /opt/kaltura/bin/kaltura-config-all.sh

The below is a sample question answer format, replace the input marked by <> with your own details:

Apache SSL Step-by-step Installation

Before you can deploy your Kaltura CE Server, you need to perform some preliminary actions such as adding the Kaltura RPM repos, setting SELinux to permissive mode and deploying MySQL. Please see pre-install steps

Note: prior to installing Kaltura, while not a must, we recommend you update the installed packages to latest by running:

# yum update

Install the basic Kaltura Packages:

# yum clean all
# yum update "*kaltura*" 
# yum install kaltura-server

Configure MySQL with the required Kaltura Settings

# /opt/kaltura/bin/kaltura-mysql-settings.sh

# service memcached restart
# service ntpd restart
# chkconfig memcached on
# chkconfig ntpd on

Nginx SSL configuration

Please see nginx-ssl-config.md

Live Streaming with Nginx and the RTMP module

Kaltura CE includes the kaltura-nginx package, which is compiled with the Nginx RTMP module.

Please see documentation here nginx-rtmp-live-streaming.md

A longer post about it can be found at https://blog.kaltura.com/free-and-open-live-video-streaming

Securing Monit

To use the monit Monitoring tab in admin console, you will need to also configure the SSL certificate for monit, see Generate PEM Instructions

Edit: /opt/kaltura/app/configurations/monit/monit.conf and add:

SSL ENABLE
PEMFILE /path/to/your/certificate.pem

The Monit HTTP daemon binds to loopback only by default [127.0.0.1]. If you wish to access the I/F from the Monitoring tab in admin console, edit /opt/kaltura/app/configurations/monit/monit.conf and change the following block to suit your needs:

set httpd port 2812
ADDRESS 127.0.0.1
allow root:@MONIT_PASSWD@

For Monit's conf documentation, please refer to https://mmonit.com/monit/documentation/monit.html, specifically, look under the "MONIT HTTPD" section.

Once done, run: /etc/init.d/kaltura-monit restart

Your Kaltura installation is now complete.

Unattended Installation

All the post install scripts optionally accept an answer file as the first argument In order to preform an unattended [silent] install, simply edit the template and pass it along to kaltura-config-all.sh.

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

# rpm -Uhv http://installrepo.kaltura.org/releases/kaltura-release.noarch.rpm
# yum clean all
# yum update "*kaltura*"

Once the upgrade completes, run:

# /opt/kaltura/bin/kaltura-config-all.sh

In the event you would like to see what changes the package includes before deciding whether or not you wish to upgrade, run:

# yum install yum-plugin-changelog
# yum changelog all kaltura-package-name-here

Remove Kaltura

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

# /opt/kaltura/bin/kaltura-drop-db.sh
# yum remove "*kaltura*"
# 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 good 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
