Upgrading Icinga Web 2

Upgrading to Icinga Web 2 2.5.x

Attention: Icinga Web 2 now requires at least PHP 5.6

Changes in packaging and dependencies

Valid for distributions:

• RHEL / CentOS 6 + 7
  • Upgrading to PHP 7.0 / 7.1 via RedHat SCL (new dependency)
  • See Upgrading to FPM for manual steps that are required
• SUSE SLE 12
  • Upgrading PHP to >= 5.6.0 via the alternative packages. You might have to confirm the replacement of PHP < 5.6 - but that should work with any other PHP app as well.
  • Make sure to enable the new Apache module a2enmod php7 and restart apache2

Discontinuing package updates

For the following distributions Icinga Web 2 won't be updated past 2.4.x anymore.

• Debian 7 wheezy
• Ubuntu 14.04 LTS (trusty)
• SUSE SLE 11 (all service packs)

Please think about replacing your central Icinga system to a newer distribution release.

Also see packages.icinga.com for the currently supported distributions.

Upgrading to Icinga Web 2 2.4.x

• Icinga Web 2 version 2.4.x does not introduce any backward incompatible change.

Upgrading to Icinga Web 2 2.3.x

• Icinga Web 2 version 2.3.x does not introduce any backward incompatible change.

Upgrading to Icinga Web 2 2.2.0

• The menu entry Authorization beneath Config has been renamed to Authentication. The role, user backend and user group backend configuration which was previously found beneath Authentication has been moved to Application.

Upgrading to Icinga Web 2 2.1.x

• Since Icinga Web 2 version 2.1.3 LDAP user group backends respect the configuration option group_filter. Users who changed the configuration manually and used the option filter instead have to change it back to group_filter.

Upgrading to Icinga Web 2 2.0.0

• Icinga Web 2 installations from package on RHEL/CentOS 7 now depend on php-ZendFramework which is available through the EPEL repository. Before, Zend was installed as Icinga Web 2 vendor library through the package icingaweb2-vendor-zend. After upgrading, please make sure to remove the package icingaweb2-vendor-zend.

• Icinga Web 2 version 2.0.0 requires permissions for accessing modules. Those permissions are automatically generated for each installed module in the format module/<moduleName>. Administrators have to grant the module permissions to users and/or user groups in the roles configuration for permitting access to specific modules. In addition, restrictions provided by modules are now configurable for each installed module too. Before, a module had to be enabled before having the possibility to configure restrictions.

• The instances.ini configuration file provided by the monitoring module has been renamed to commandtransports.ini. The content and location of the file remains unchanged.

• The location of a user's preferences has been changed from <config-dir>/preferences/<username>.ini to <config-dir>/preferences/<username>/config.ini. The content of the file remains unchanged.

Upgrading to Icinga Web 2 Release Candidate 1

The first release candidate of Icinga Web 2 introduces the following non-backward compatible changes:

• The database schema has been adjusted and the tables icingaweb_group and icingaweb_group_membership were altered to ensure referential integrity. Please use the upgrade script located in etc/schema/ to update your database schema

• Users who are using PostgreSQL < v9.1 are required to upgrade their environment to v9.1+ as this is the new minimum required version for utilizing PostgreSQL as database backend

• The restrictions monitoring/hosts/filter and monitoring/services/filter provided by the monitoring module were merged together. The new restriction is called monitoring/filter/objects and supports only a predefined subset of filter columns. Please see the module's security related documentation for more details.

Upgrading to Icinga Web 2 Beta 3

Because Icinga Web 2 Beta 3 does not introduce any backward incompatible change you don't have to change your configuration files after upgrading to Icinga Web 2 Beta 3.

Upgrading to Icinga Web 2 Beta 2

Icinga Web 2 Beta 2 introduces access control based on roles for secured actions. If you've already set up Icinga Web 2, you are required to create the file roles.ini beneath Icinga Web 2's configuration directory with the following content:

[administrators]
users = "your_user_name, another_user_name"
permissions = "*"

After please log out from Icinga Web 2 and log in again for having all permissions granted.

If you delegated authentication to your web server using the autologin backend, you have to switch to the external authentication backend to be able to log in again. The new name better reflects what's going on. A similar change affects environments that opted for not storing preferences, your new backend is none.
