}

Usage of “test” module in “/etc/puppet/manifests/site.pp”

class { 'aem::author':
message => author,   #specify the type of AEM installation to create.Only author/publisher valid
port => 7502,           #specify the port on which AEM will listen.
}
class { 'aem::publish':
message => publish,   #specify the type of AEM installation to create.Only author/publisher valid
port => 7503,           #specify the port on which AEM will listen.
}

Note: By default installation path set to /tmp to change the default path need to change parameter $installation_dir with your path in file
“/etc/puppet/modules/aem/manifests/publish.pp” for “publish”
“/etc/puppet/modules/aem/manifests/author.pp” for “author”

Other parameter:
Other parameter value defined in author.pp and publish.pp also modify as per requirements are:

$MaxPermSize = '256' #Specify the java MaxPermSize
$Xmx = '1024', #Specify the java max heap size

AEM quickstart jar file with license.properties

AEM license.properties should be placed “/etc/puppet/modules/aem/templates/” and renamed as license.properties.erb as has dependency in author.pp and publish.pp

Note:
If you don’t want to rename then you need to make changes accordingly in dependency files.

In “/etc/puppet/modules/aem/templates/launchinstance.sh.erb” you need to specify source from where you downloading cq-quickstart-5.6.1.jar in line number 12.

Moving large files like cq-quickstart-5.6.1.jar from puppetmaster to puppet-agents lead to puppetmaster high load-average or failure.

Apply the module on puppet agents

puppet agent -tv --debug
