installing

  1. dependencies
  2. boot script
  3. passenger
  4. sphinx
  5. zena@alwaysdata

This article is a walkthrough to help installation of the dependencies. I am writing this after having installed everything, so please give me some feedback so that I can correct this tutorial if I missed something (mailing-list).

debian (lenny and up)

You can use the install script.

Known issues:

You might need to start mysql server if “cap” command fails:

$ /etc/init.d/mysql start

If the server won’t start, you may have a problem with “rmagick”. Try running “convert” and if you get convert: error while loading shared libraries: libMagickCore.so.2, you need to add /usr/local/lib to the search path for libraries:

$ ldconfig /usr/local/lib
$ gem install rmagick

That’s all you need on debian, the rest (apache2 configuration, database creation, etc) is done with capistrano.

Mac OS X

Read rails stack under OS X Snow Leopard and then run:

$ sudo gem install zena

    Why only MySql database? I want to use Postgresql, but Zena install procedure is very obstrusive and rigid. Is there any reason for not supporting Postgresql or other Rails compatible database?

    Thank you.

    There are some mysql specific parts that would need to be be abstracted to work with other databases (date intervals, fulltext search).

    That’s not a lot, but I first needed to have zena work on a database that was easy to install at the time I started the project (2005).

    If you think Postgresql/SQLite compatibility is a must-have, please fill a ticket on zena.lighthouseapp.com with some justification so someone finds the motivation to fix this soon enough.

    Updated install script. Tested on a clean debian etch.

    Alain: this is a problem with newer (probably gettext) gems. Until I move all gems in “vendor” to avoid such problems, here is the list of gems known to support current version of zena: unknown link.

    Hi Gaspard,

    i watched the videos and i’m really impressed with Zena. It is awesome.

    anyway i leave this comment here to add 1up to PostgreSQL request and to add 1up for Phusion Passenger support.

    I know that doing this alone can be time consuming but IMHO Zena should have at least 2 DB support and definitely Passenger support.

    keep the good work going and “have fun building the house” =)

    Hi cga !

    We will definitely support passenger for our 1.0 release in October (I even contributed to passenger to support multiple hosts).

    As for postgresql, we will add support for this DB when we integrate Sphinx (to keep fulltext search while having better transactions).

    [edit] Overall simplification of the install process now that zena is a gem.

    Hi Gaspard,

    I’m cga, I came here to check PGSQL support. it seems there’s none yet unfortunately.

    Can’t wait to have Zena to work on my stack:

    Debian Lenny
    Nginx w/ Passenger
    PostgreSQL

    keep up the good work

    Hi cga !

    The default stack for the 1.0 release will probably be Apache2+Passenger. Adding support for PostgreSQL should be a matter of weeks after the 1.0 release. Same for Nginx.

    I know we are a little late with this 1.0 release but we wanted to implement some important changes, mainly property and rubyless. This work is coming to an end (see the zena, the peaceful CMS / Ruby on Rails CMS).

    Hi Gaspard,

    nice to now this!!!!! can’t wait for it.

    I just removed debian default ruby and installed Ruby Enterprise Edition and of course Nginx w/ Passnger.

    looking forward for Zena 1.0 w/ PostgreSQL and the above support.

    keep up the good work.
