CUE 2.9.6-1 requires version 6.8 of the Escenic Content Engine and CUE Print/Newsgate 3.11.0 (latest). Contact your customer service manager for availability of corresponding Newsgate versions on previous release tracks.
Before installing CUE, ensure that the back-end systems you are going to use it with have been upgraded accordingly:
If CUE is to use an Escenic back end, make sure your Escenic Content Engine is upgraded to version 6.8 or higher
If CUE is to use a CCI Newsgate back end, make sure that Newsgate has been upgraded to a suitable version (see above)
CUE also requires the use of an SSE Proxy to manage the delivery of Server-sent Events from the Escenic Content Engine to CUE clients. This means that an Escenic SSE Proxy must have been installed and configured to manage SSE for the Content Engine, and the Content Engine must have been configured to direct SSE connection requests to the SSE Proxy. For general information on how to install and configure an SSE Proxy, see the SSE Proxy documentation. For specific guidance on how to configure the Content Engine and the SSE Proxy to work together with CUE, see Configure an SSE Proxy Connection for CUE .
The instructions given here are based on the use of an nginx web server, running on Ubuntu.
To install CUE:
Log in via SSH from a terminal window.
Switch user to root:
If necessary, add the Escenic
aptrepository to your list of sources:
#curl --silent http://user:firstname.lastname@example.org/repo.key | apt-key add -
#echo "deb http://user:email@example.com stable main non-free" >> /etc/apt/sources.list.d/escenic.list
where user and password are your Escenic download credentials (the same ones you use to access the Escenic Maven repository). If you do not have any download credentials, please contact Escenic support.
You need to install version 1.7.5 or higher of nginx. The version available in the Ubuntu 14.04 repositories is too old, so in order to ensure that you install a new enough version, you need to add a repository containing a more recent version:
Update your package lists:
Download and install CUE. The recommended way to do this is:
#apt-get install cue-web-3.0
Download and install nginx
#apt-get install nginx
