    Installation of Jboss

Download Jboss 7 from [jboss donwnload site] (http://www.jboss.org/jbossas/downloads)
Extract jboss in the proper place for example /usr/share
$ cd /usr/share
# tar xvf /home/xxxxx/Downloads/jboss-as-7.0.2.Final.tar.gz

Installation of mod_cluster

Download the libs, [actually mod_cluster 1.1.3] (http://www.jboss.org/mod_cluster/downloads/1-1-3)
Extract the libs
$ cd /home/xxxx/Downloads
$ mkdir ./mod_cluster_libs
$ cd ./mod_cluster_libs
$ tar xvf ./mod_cluster-1.1.3.Final-linux2-XXXX-so.tar.gz
$ rm ./

Copy libs (not all, mod_proxy_ajp.so, mod_proxy_http.so and mod_proxy.so NO) to apache modules dir (i.e /usr/lib/apache2/modules/)
# cp ./mod_advertise.so  ./mod_manager.so  ./mod_proxy_cluster.so  ./mod_slotmem.so  /usr/lib/apache2/modules/

Configuration of mod_cluster in Jboss

Configure jboss Standalone mode to enable mod_cluster. Edit the standalone.xml file in $JBOSS_HOME/standalone/configuration/standalone.xml and add this two lines in their sections
Extension
<extension module="org.jboss.as.modcluster"/>

Subsystem
<subsystem xmlns="urn:jboss:domain:modcluster:1.0" />

Configuration of mod_cluster in apache

Create two files in mods-available (/etc/apache2/mods-available)
mod_cluster.load
LoadModule proxy_module /usr/lib/apache2/modules/mod_proxy.so
LoadModule proxy_http_module /usr/lib/apache2/modules/mod_proxy_http.so
LoadModule proxy_ajp_module /usr/lib/apache2/modules/mod_proxy_ajp.so
LoadModule slotmem_module /usr/lib/apache2/modules/mod_slotmem.so
LoadModule manager_module /usr/lib/apache2/modules/mod_manager.so
LoadModule proxy_cluster_module /usr/lib/apache2/modules/mod_proxy_cluster.so
LoadModule advertise_module /usr/lib/apache2/modules/mod_advertise.so

mod_cluster.conf

And enable the module
# a2enmod mod_cluster

Configuration of jboss (mod_cluster/proxy) in apache

Create a file (virtual host) for jboss in sites-available (/etc/apache2/sites-available)
jboss
NameVirtualHost *:80
<VirtualHost *:80> 
    #ServerAdmin info@domain.de
    ServerName jboss.mdiss.info
    ServerAlias jboss.mdiss.info

    ProxyPass / balancer://mycluster stickysession=JSESSIONID|jsessionid nofailover=On
    ProxyPassReverse / balancer://mycluster
    ProxyPreserveHost On

    <Location />
        Order deny,allow
        Allow from All
    </Location>

   <Location /mod_cluster-manager>
      SetHandler mod_cluster-manager
      Order deny,allow
      #Deny from all
      Allow from 127.0.0
   </Location>

</VirtualHost>

Fix mod_cluster log problem

There is a problem with mod_cluster  (in ubuntu?), needs the log directory in /etc/apache2
We can do two things, create the dir or create a symbloic link to /var/log/apache2
Creating the dir
# mkdir /etc/apache2/logs

Creating the symbolic link
#ln -s /var/log/apache2 /etc/apache2/logs

Install Jenkins

Download and deploy jenkins war

We download Jenkins from the [site] (http://mirrors.jenkins-ci.org/war/latest/jenkins.war)
and we deploy the war.
Connect to the jboss admin console
# $JBOSS_HOME/bin/jboss-admin.sh
$ connect
$ deploy /home/xxxx/Downloads/jenkins.war
$ exit
