Install the following tools to aid in the update process.


apt-get install subversion sshpass


yum install svn sshpass


To aid in database schema comparisons, install mysqlworkbench. With this tool you will be able to compare database dumps, and create delta alter scripts to fix any missed updates.

Important files

Kaltura configuration files:


Kaltura log files


Kaltura deployment scripts for rebuilding parts of kaltura and defaults


Kaltura 9x bin, installing & configuring


1 Normal installation

Before upgrading any Kaltura release. You should first install and verify that the new Kaltura release is working correctly. Installing Kaltura has been documented on github. It is advised you use the new RPM based installation.

1.1 Verify

After successfully installing Kaltura. First run:


Only when everything passes. Proceed to the next step.

1.2 Export working Kaltura schemas & routines

Export the following Kaltura schemas:

  • kaltura
  • kalturadw
  • kalturadw_bisources
  • kalturadw_ds
  • kalturalog
  • kaltura_sphinx_log


1.3 Export data

While upgrading kaltura, some data migrations are missed. These are:

  • delivery_profile (Export all data)
  • dynamic_enum (Export all data)
  • partner (Export all partners with id < 100)
  • ui_conf (Export all uiconfs belonging to partner < 100 )

The exporting is best done by using adminer or phpmyadmin.

1.4 Register triggers and procedures

Open the mysql information_schema database in phpmyadmin or adminer. Save or note all records in: information_schema.triggers and information_schema.procedures. This is important because you will be able to check if the system has been successfully upgraded.

2 Setup the upgrade

After installing, verifying and exporting the healthy Kaltura system. We setup the actual upgrade process.

2.2 Stop Kaltura services

service kaltura-monit stop service kaltura-batch stop service kaltura-sphinx stop

2.3 Drop schemas

Drop the following schemas:

  • kaltura
  • kalturadw
  • kalturadw_bisources
  • kalturadw_ds
  • kalturalog
  • kaltura_sphinx_log

2.4 Import production database

Import the production database from a backup, or any other sqldump. After restoration, please verify that you have the following databases again:

  • kaltura
  • kalturadw
  • kalturadw_bisources
  • kalturadw_ds
  • kalturalog
  • kaltura_sphinx_log

2.5 Import production data

Import the contents of your production servers /opt/kaltura/web to the new server.

3 Upgrading

After completing the setup phases. Execute the following steps to start the Kaltura upgrade.

3.1 Create config file

Implement the suplied as Take note:

  • Select only the releases that apply to your upgrade.
  • Upgrades are executed in the order you configure them.
  • Configure the root user & password to avoid authentication issues.
  • Configure the rest to your own specification.

3.2 Add the Kaltura svn host to the known_hosts file


svn export svn+ssh://

You can just cancel after the host has been added.

3.3 Export releases

Run the following script:


This will build all the releases for upgrading.

4.4 Configure releases

Run the following script:


This will supply the required configuration files for all exported releases.

4.5 Execute legacy upgrades

Before starting the upgrade run:

service kaltura-shpinx start

Some updates need sphinx to be running, after all upgrades are completed. We will restore & reindex shpinx later on.



This might take anywhere between 1-2 hours depending on how many releases you intend to upgrade. While upgrading you can watch the status by using:

tail -f [log]

4.6 Verify the upgrades

Inspect the run-update log for your upgrade, and inspect errors if they occurred. For failed upgrades you will have to inspect those files and compare them to the results. If a lot of them occurred, fix them, and repeat from step 2.4.

4.7 Run current Kaltura updates

After all legacy upgrades have been completed run the RMP upgrades.

/opt/kaltura/bin/ And /opt/kaltura/bin/

5 Verify schema state

After running all upgrades&updates, we need to check the schema for any misses. This is where the backups of the healthy system come in hand. Import the healthy exports into another mysql server.

5.1 Export schema states

On the healthy system

mysqldump -uroot -p --routines --no-data kaltura > kaltura.healthy.sql

On the updated system

mysqldump -uroot -p --routines --no-data kaltura > kaltura.update.sql

5.2 Compare and create delta script

Open mysql-workbench, create a new schema and navigate to: database > synchronize with any source.

As the source select the kaltura.healthy.sql As the destination select the kaltura.update.sql Specify the alter script file to your own liking

Continue the wizard to completion.

5.3 Inspect delta alter file

Inspect the generated alterscript. Take note that if you have any add column statements, you might have a missed update. Because new fields probably need to be migrated, take extra care inspecting those.

5.4 Run the alter script

Execute the alter script on the upgraded system.

5.5 Repeat

Mysql workbench is not perfect. Sometimes you will need to repeat the process until the wizard no longer finds any differences between healthy and upgraded.

6 Restore data

This step restores missed or otherwise default provided data into Kaltura.

6.1 Partner data

Clear all system partners:

mysql -uroot -p kaltura -e "DELETE FROM partner WHERE id < 100"

Import healthy system partners:

mysql -uroot -p kaltura < [step 1.3 partner export.sql]

Check the batch user secret in /opt/kaltura/app/configurations/batch against the user in the database. And change if needed.

6.2 Default uiconfs

Clear uiconfs

mysql -uroot -p kaltura -e "DELETE FROM ui_conf WHERE partner_id < 100"

Import uiconfs

mysql -uroot -p kaltura < [step 1.3 uiconf export.sql]

Redeploy uiconfs

php /opt/kaltura/app/deployment/uiconf/deploy_v2.php --ini="/opt/kaltura/web/flash/kmc/v5.37.27/config.ini"

6.3 Restore dynamic enums

Clear dynamic enums

mysql -uroot -p kaltura -e "TRUNCATE dynamic_enum"

Import enums

mysql -uroot -p kaltura < [step 1.3 dynamic enum export.sql]

Delete kaltura classmap caches

rm -Rf /opt/kaltura/app/cache/*

To avoid APC caches as wel, restart apache

service httpd restart

6.4 Restore delivery profiles

Clear profiles

mysql -uroot -p kaltura -e "TRUNCATE delivery_profile"

Import profiles

mysql -uroot -p kaltura < [step 1.3 delivery export.sql]

6.5 Rebuild sphinx

Because sphinx was on during all the upgrades, it probably has been seriously mangled.

Shutdown sphinx

service kaltura-shpinx stop

Backup and move sphinx data

mv /opt/kaltura/sphinx/kaltura* [backup]

Backup and move sphinx binlogs

mv /opt/kaltura/log/sphinx/data/binlog.* [backup]

Start sphinx again

service kaltura-sphinx start

Check sphinx is running

service kaltura-sphinx status

Re-index site

for FILE in $(ls /opt/kaltura/app/deployment/base/scripts/Sphinx); do php $FILE; done

If any errors occur during the re-indexing. Also re-execute the install & insert scripts.

7 Verify the new installation

After all the steps above have been completed, rerun the execute script to check the system status/
