Zend Server 6 is the latest Application Server for PHP development supported and distributed by Zend, it's an awesome piece of software the lets you deploy and manage your PHP apps in no time.
There are tons of new features on this version compared to what we had previously on ZS 5. Totally recommended!
Below i'm describing how to install it on Ubuntu Server 13.04:
login on your server as root:
1) edit the /etc/apt/sources.list file and add the following entry:
deb http://repos.zend.com/zend-server/6.1/deb_ssl1.0 server non-free
*Note: this repo will also work with Ubuntu 12.04/12.10
update your repositories
# apt-get update
add the public key with this command:
# wget http://repos.zend.com/zend.key -O- |apt-key add -
and finally, install the packages :
# apt-get install install zend-server-ce…
Sometimes when updating or upgrading different packages on your Ubuntu specially kernel updates, Zend Server tends to break up and the whole packages system too, you usually get errors like "bad inconsistency" of package php-zend-server-ce-php-5.x and you are asked by the system to reinstall this package but that's also impossible due to the changes the update has performed.
In order to fix this issue try following the next steps:
sudo /usr/local/zend/bin/zendctl.sh stop => stop zend server service
sudo rm -rfv /usr/local/zend/tmp/* => remove zend server's cache and/or temp files
sudo /usr/local/zend/bin/zendctl.sh start => start the service again
and reinstall the zend-server-ce-php-5.x package using synaptic, or dpkg.
Hope this helps!
