eZ Publish 5.0 is built to rely on existing technologies and standards, mainly:
- PHP scripting 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.
The most safe and optimized stack for eZ Publish Platform. The stack is supported and certified for eZ Publish Platform 5.0. 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 5.0 is based on Red Hat Enterprise Linux 6. The detail of the stack can be seen in the table below.
Single mode & Cluster mode
PHP (mod_php) + PHP CLI
PHP + PHP CLI extensions
eZ Publish extensions
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 5.0 are:
- SUSE Linux Enterprise Server 11 SP2(**)
- Debian 6
The detail of the stacks can be seen in the table below.
PHP (mod_php) + PHP CLI + apache
eZ Publish extensions
* 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.
** : eZ Publish 5.0 is the last version supporting Oracle, in 5.0 it is only supported in "legacy stack". It is not supported on 5.1 and higher versions on eZ Publish, however is planned to return in "eZ Platform", aka "6.x".
eZ Publish can run and execute on many more platforms than the ones listed above, including (but not limited to) the following operating systems if they pass the Symfony requirements:
- Windows 2000/XP/Vista/7/2008
- Mac OSX server
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.
eZ Publish is developed to work properly and support the following browser configurations for administrator users:
- Firefox: Latest stable version. Tested on Firefox 16.
- Google Chrome: Latest stable version. Tested on Chrome 21”
- Internet Explorer: 8 & 9. Tested on IE 9
- Safari: 6. Tested on Safari 6.0 on Mac OSX 10.8
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.
