eZ Publish 5 eZ Publish software is built to rely on existing technologies and standards, mainly:

• PHP scripting

language

• language 

• SQL database

• Java JRE when eZ Find search engine is used

To answer the question "Is my platform supported by eZ Publish?", several things must be taken into consideration. The following tables gives you the details of the platform requirements for the latest eZ Publish release.

Reference platforms

The most safe and optimized stack for eZ Publish Platform. The stack is supported and certified for eZ Publish Platform 5. This means that our QA certification team has successfully run intensive certification tests on the platform, and that we can fully support the platform in the scope of an eZ Publish Subscription.

The reference stack for eZ Publish Platform 5 is based on Red Hat Enterprise Linux 6. The detail of the stack can be seen in the table below.

Supported non-reference stacks (approved)

These stacks are also tested, but not as extensively as our reference stacks. These stacks still benefit from the full support and maintenance guarantees provided with the eZ Publish Platform Subscription, but more issues might occur during normal operations, performance might be lower and issues take longer to resolve.

The supported non-reference stacks for eZ Publish Platform 5 are:

• SUSE Linux Enterprise Server 11 SP2(**)
• Debian 6 

The detail of the stacks can be seen in the table below.

* eZ Content Staging, REST API and Public API (including Symfony stack) are using PDO for database access and is hence not tested at all for Oracle as its driver is experimental, see: Oracle PDO driver page.

 ** Issues have been identified with the SLES 11 SP2 in regards of the PHP stack. eZ Systems can not provide a workaround and the only recommendation is to wait for a new service pack for SLES.

Compatible platforms

eZ Publish can run and execute on many more platforms than the ones listed above, including (but not limited to) the operating systems listing below if they pass the Symfony requirements.

However, eZ Systems doesn't insure and guarantee quality operation of an eZ Publish Platform installation if it is running on any platform not listed as supported. eZ Publish Enterprise Subscriptions are still available for compatible platforms, but the guarantee and the product support will not apply and although you will receive various maintenance releases and services, no bug fix guarantee will apply to issues related to the platform. Maintenance and monitoring tools will not be available. eZ Systems does not advise merely compatible platforms for production use.

Compatible platform:

• Most Linux operating system (Fedora, CentOS, Ubuntu...)
• Solaris 
• OpenSolaris
• Windows 2000/XP/Vista/7/2008 (only on legacy stack or legacy mode)
• Mac OSX server

...

eZ Publish is developed to work properly and support the following browser configurations for administrator users:

• Mozilla® Firefox®, most recent stable version (tested on Firefox 23). eZ makes every effort to test and support the most recent version of Firefox.  

• Google Chrome™, most recent stable version (tested on chrome 29). Chrome applies updates automatically; eZ makes every effort to test and support the most recent version.

• Microsoft® Internet Explorer® versions 9, and 10. We recommend using the latest version.

• Apple® Safari® 6.x on Mac OS X. Apple Safari on iOS isn’t supported.

Please note that the interface will display and behave optimally in any browser that supports HTML 5.0, CSS 3.0 and ECMAScript 5. If these technologies are not supported the system will gracefully appear with simpler design/layout but will still be accessible through standard/default HTML elements.

Known limitation on ImageMagick 6.5.4-7

Please be aware that if you have the [URLTranslator]/TransformationGroup legacy setting set to urlalias_iri in your site.ini (if you are running eZ Publish in legacy mode), then special character escaping with ImageMagick 6.5.4-7 may not work as expected.

This is caused by an ImageMagick limitation which fails on escaping  the following special characters: ~*?[]{}<>
If you are using this version of ImageMagick and urlalias_iri as TransformationGroup, please be sure to avoid using those characters in file names, or it will generate issues with eZ Publish.

• XHTML  / HTML5

• XML 1.0

• Java JRE Oracle/Sun/OpenJDK when eZ Find search engine is used
