Installation

  • Zend Server 8.0.2 supports both new installations and upgrades from Zend Server 6.x and 7.x versions. Upgrading from a version prior to Zend Server 6.0 is not supported. If you would like to upgrade a Zend Server that's older than 6.0, you should first upgrade to a newer version and only then upgrade to 8.0.2.

  • For Linux users we recommend to install a new - or upgrade an existing - Zend Server installation using the supplied Repository Installer script. The script ensures that the correct repositories are set, verifies system requirements and issues the correct package management commands to set Zend Server up properly. While it’s still possible to install Zend Server by manually setting up repositories, we advise to always use the installation script.

  • For detailed installation instructions for all supported operating systems, please refer to the Zend Server Installation Guide​.  For a full list of system requirements, see the Zend Server System Requirements. 

  • If you previously installed Zend Guard Loader on your Zend Server 8.0.2, once updating your installation with this package, you will need to repeat installation steps for Zend Guard Loader according to the README instructions.

Limitations and Known Issues

The following issues are known at the time of the 8.0 release:

General

  • Zend Server cannot communicate with MySQL databases that are configured with old_passwords=1 (ZSRV-8104)

  • Misconfiguring LDAP authentication can result in the user being locked out of their Zend Server console. If this occurs, reset your Zend Server password. For more information, see the Zend Server User Guide.

  • Session Clustering does not support value=6 for the php.ini directive session.hash_bits_per_character (the Zend Server UI does not currently warn about this issue).

  • Nginx Deployment: deploying to the root of the default virtual host does not work out-of-the-box and causes configuration problems (ZSRV-10098). Workaround: comment out the location / entry in /etc/nginx/conf.d/default.conf

        #location / {

        # include /etc/nginx/fastcgi.conf;

        #

        # root /usr/share/nginx/html;

        #

        # index index.php index.html index.htm;

        # }
