Firs of all you need a CentOS operating system with mysql, ruby 1.9 and passenger installed

If you don’t have this or you don’t know how to do it, just follow the simple instructions on these 2 posts:

Installing Ruby 1.9 on CentOS

Installing Phusion’s Passenger on CentOS (for Ruby 1.9)

Once you are done with this you are ready to move forward.

First you need to copy the following directories from your GeneXus installation to the CentOS server.

From under “gxruby” copy the “linux” and “generic” directory both under the same subdirectory.

In my case I’ve created a new directory on the server called “gxruby” (original 🙂 ), and put them there.

Now before you run the installation script, in order to work properly under CentOS you have to do the following:

1. The installation script is based on Debian, so it expects to have certain libraries installed in places where CentOS doesn’t normally used them
   specially the “libmysqlclient”. On CentOS these library is called “libmysqlclient.so.15.0.0” and it’s under “/usr/lib/mysql/”, but in the installation
   script it should be under “/usr/local/lib/” so we’ll have to link it to the new location, we do this with the following command:
   $ ln -s /usr/lib/mysql/libmysqlclient.so.15.0.0 /usr/local/lib/libmysqlclient.so
2. Under the subdirectory “gxruby/generic/gx_lucene” (this is where you copy from the GeneXus machine), you have to edit the script “build_make.sh”.
   In reality, because this file is corrupted on GeneXus Evo1 U3, it’s better if you delete it an create a new one with the same name with the following contente:
   #!/bin/sh
   tar -xzf clucene-core-0.9.21b.tar.gz
   cd clucene-core-0.9.21b
   sh autogen.sh
   sh configure
   make
   make install
   cd ..
   ruby extconf.rb –with-clucene-include=’clucene-core-0.9.21b/src’ –with-clucene-lib=’clucene-core-0.9.21b/src/.libs’ –with-ldflags=’-lclucene’
   make
   mkdir lib
   mv CLucene_gx.so lib
   gem build build_gem.rb
   gem install  CLucene_gx-0.1.1-x86-linux
   
   

NOTE:

In addition, if you are using a 64 bit platform replace the last line of the script for gem install  CLucene_gx-0.1.1-x86_64-linux

Now you are ready to run the installation script that will install all GeneXus gems on your system.

Go to “./gxruby/linux”, and run the “installgems.bash” script.

In order to do that just change the mode of the file to “executable” with $ chmod +x installgems.bash

and then runt $ ./installgems.bash

Now, you are ready to deploy your GeneXus Ruby applications.

If you don’t know how to do it, follow the next post where I’m going to walk you through the deployment process

😉

As a prerequisite you have to have installed Ruby 1.9.x on your CentOS system.

If you don’t know how to do it, follow the instructions on this post:

Installing Ruby 1.9 on CentOS

Once you are ready follow the next steps:

On a terminal type:

$ gem install passenger

$ passenger-install-apache2-module

This last command is going to walk you through the process of installation,

helping you install whatever is missing on your system and at the end giving the instructions

to “patch” your apache’s configurations file.

On my case, I had to install the following modules:

$ yum install httpd-devel

$ yum install apr-devel

$ yum install apr-util-devel

After installing them re-run the command again

$ passenger-install-apache2-module

And then edit the apache configuration

/etc/httpd/conf/httpd.conf

Ad the following lines to the file:

Stopping httpd:                                            [  OK  ]

Starting httpd:                                            [  OK  ]

Now you are ready to go.

Test the site http://ruby.1oc.com/

$ sudo yum groupinstall 'Development Tools' $ sudo yum install readline-devel $ cd /usr/local/src $ wget ftp://ftp.ruby-lang.org:21//pub/ruby/1.9/ruby-1.9.2-p0.tar.gz $ tar xzvf ruby-1.9.2-p0.tar.gz $ cd ruby-1.9.2-p0 $ ./configure && make $ sudo make install

test the installations with

$ruby -v

ruby 1.9.2p0 (2010-08-18 revision 29036) [i686-linux]

Now, just in case the source became unavailable I'm including it here:

ruby-1.9.2-p0.tar.gz

NOTE:

If you're going to use Ruby for Genexus, the version 1.9.2 and above are NOT suported as this date, instead use the version 1.9.1

ruby-1.9.1-p429.tar.gz
