You’ll need first mod_jk installed, follow Building Guide.

Create /etc/apache2/other/jk.conf :

# Load JK Module
LoadModule jk_module     libexec/apache2/mod_jk.so
# JK workers.properties
JkWorkersFile /etc/apache2/other/workers.properties
# JK shared memory location
JkShmFile     /var/log/apache2/mod_jk.shm
# JK logs
JkLogFile     /var/log/apache2/mod_jk.log
# JK log level [debug/error/info]
JkLogLevel    info
# JK timestamp log format
JkLogStampFormat "[%a %b %d %H:%M:%S %Y] "

Create /etc/apache2/other/workers.properties

worker.list=jenkins,watch,manage

# Set properties for worker jenkins (ajp13)
worker.jenkins.type=ajp13
worker.jenkins.host=localhost
worker.jenkins.port=8009

# status workers
worker.watch.type=status
worker.watch.read_only=true
worker.watch.mount=/user/status/jk
worker.manage.type=status
worker.manage.mount=/admin/status/jk

I choose to use VirtualName Hosting and so defined one into /etc/apache2/extra/httpd-vhosts.conf :

NameVirtualHost *:80

<VirtualHost *:80>

    ServerName  mbpbuilder.hgomez.net
    ServerAlias mbpbuilder
    ServerAdmin [email protected]

    ErrorLog    "/var/log/apache2/mbpbuilder.org-error_log"
    CustomLog   "/var/log/apache2/mbpbuilder-access_log" common

    JkMount  /* jenkins

</VirtualHost>
