Well, to be more honest, I've started to tinker with Puppet, using it to … create a group and a user on a Linux server :-)
Initially, I started with a mixture of Linux boxes; one Ubuntu 16.04 and one Red Hat 6.6.
This may have led to my confusion ….
So I started again with a pair of Red Hat 6.6 boxes.
In both cases, I added the appropriate Red Hat Enterprise Linux 6 repository ( el-6 ): -
sudo gpg --keyserver pgp.mit.edu --recv-key 7F438280EF8D349F
sudo gpg --list-key --fingerprint 7F438280EF8D349F
On the Puppetmaster server, I installed the Puppet Server binary: -
sudo yum install puppetserver
On the Puppet client, I installed the Puppet Agent binary: -
sudo yum install puppet-agent
and started the Puppet service: -
sudo service puppetserver start
Again, on the client, I setup the Puppet environment: -
vi /etc/puppetlabs/puppet/puppet.conf
[main]
server=client.uk.ibm.com
certname=server.uk.ibm.com
certname=server.uk.ibm.com
started the agent: -
sudo /opt/puppetlabs/bin/puppet resource service puppet ensure=running enable=true
and invoked the Puppet test: -
sudo /opt/puppetlabs/bin/puppet agent —test
Info: Caching certificate_revocation_list for ca
Info: Using configured environment 'production'
Info: Retrieving pluginfacts
Info: Retrieving plugin
Info: Caching catalog for client.uk.ibm.com
Info: Applying configuration version '1475866304'
Info: Using configured environment 'production'
Info: Retrieving pluginfacts
Info: Retrieving plugin
Info: Caching catalog for client.uk.ibm.com
Info: Applying configuration version '1475866304'
This generates a Certificate Request on the Puppet server, which I then signed: -
sudo /opt/puppetlabs/bin/puppet cert sign client.uk.ibm.com
Finally, I used the Puppet resource command to generate the syntax for group and user creation: -
sudo puppet resource -e group wasadmins
sudo puppet resource -e user wasadmin
to allow me to create a manifest: -
vi /etc/puppetlabs/code/environments/production/manifests/site.pp
group { 'wasadmins':
ensure => 'present',
gid => '506',
}
user { 'wasadmin':
ensure => 'present',
home => '/home/wasadmin',
password => '$6$wjKn96pk$2yZ.jzYYDTrlc7NhvdRprJ1MzkSKfjCK8.BcBe1Cnh1viIA7S98mlnHPEPk0NYdjPkT9bhaqOuxb5/QQq2cl9.',
password_max_age => '99999',
password_min_age => '0',
shell => '/bin/bash',
uid => '509',
gid => '506',
comment => 'wasadmin',
groups => 'wasadmins',
}
I re-ran the Puppet Agent test: -
sudo /opt/puppetlabs/bin/puppet agent —test
Info: Using configured environment 'production'
Info: Retrieving pluginfacts
Info: Retrieving plugin
Info: Caching catalog for mta2015a.uk.ibm.com
Info: Applying configuration version '1475868429'
Notice: /Stage[main]/Main/Group[wasadmins]/ensure: created

Info: Retrieving pluginfacts
Info: Retrieving plugin
Info: Caching catalog for mta2015a.uk.ibm.com

Notice: /Stage[main]/Main/Group[wasadmins]/ensure: created
Notice: /Stage[main]/Main/User[wasadmin]/ensure: created
Notice: Applied catalog in 0.07 seconds
Now to extend this to create ALL the users and groups, then install DB2 and IBM MQ and then ……...
As ever, I had plenty of references: -
