Quick StoRM WebDAV deployment on CentOS 7 with Puppet 7

Assuming that:

• the host satisfies the StoRM System Requirements
• the Getting Started sections related to repositories have been followed

we will deploy all the services in 2 steps:

• Prepare node
• Install services

Prepare node

This part of the guide explains how to brief prepare a node to install StoRM WebDAV service. We are aware that there are a lot of ways to do these things and each site administratos knows what is better for his site. This guide is ispired from how we test the clean deployment of our service.

Host certificate and key

Be sure you have your host certificate and key stored at /etc/grid-security. Check also if your host certificate is not expired.

$ ls /etc/grid-security/hostcert.pem
$ ls /etc/grid-security/hostkey.pem
$ openssl x509 -in /etc/grid-security/hostcert.pem -noout -text

Install Puppet 7

Install Puppet 7 as follow:

rpm -Uvh https://yum.puppet.com/puppet7-release-el-7.noarch.rpm
rpm -Uvh https://yum.puppet.com/puppet-tools-release-el-7.noarch.rpm
wget http://yum.puppet.com/RPM-GPG-KEY-puppet-20250406
rpm --import RPM-GPG-KEY-puppet-20250406
yum install -y puppet

Install Puppet modules

Install the following puppet modules:

# Puppet Standard Library
puppet module install puppetlabs-stdlib --version '8.6.0'
puppet module install puppetlabs-apt --version '8.5.0'
# fetch-crl and all CA certificates
puppet module install puppet-fetchcrl --version '5.1.0'
# EPEL repo
puppet module install puppet-epel --version '4.1.0'
puppet module install puppetlabs-firewall --version '5.0.0'
puppet module install saz-sudo --version '14.0.0'
# UMD4 repo
puppet module install cnafsd-umd4
# VOMS VO configuration
puppet module install cnafsd-voms
# StoRM services and utils
puppet module install cnafsd-storm

Setup node

Apply this setup.pp:

include epel
include umd4
include fetchcrl

# install and configure dteam vo
include voms::dteam

# storage root directories for all the storage areas
# Just for test purpose. In production you should not need this part.
$storage_area_root_directories = [
  '/storage/dteam',
  '/storage/dteam/disk',
  '/storage/dteam/tape',
]
storm::rootdir { '/storage': }
storm::sarootdir { $storage_area_root_directories: }

puppet apply setup.pp

Services

Example of manifest.pp

The following configuration install and configure StoRM WebDAV service. A pair of dteam VO storage areas are defined for Backend and WebDAV services.

Example of manifest.pp:

# Edit this value for your FQDN hostname
$host='storm-test.example.org'

class { 'storm::webdav':
  storage_areas => [
    {
      'name'          => 'dteam-disk',
      'root_path'     => '/storage/dteam/disk',
      'access_points' => ['/disk'],
      'vos'           => ['dteam'],
    },
    {
      'name'          => 'dteam-tape',
      'root_path'     => '/storage/dteam/tape',
      'access_points' => ['/tape'],
      'vos'           => ['dteam'],
    },
  ],
}

Then apply it as follow:

puppet apply manifest.pp

Go to StoRM Puppet module site to read all the configuration values for each StoRM Puppet class.
