Servermanagement with puppet – Part 1

The Environment:

puppetmaster: The puppetmaster
pc1: The first testclient
pc2: The second testclient

Domain: domain.local

Note: I used Ubuntu 9.04 in all servers.

Puppetmaster installation

aptitude install puppetmaster

Activate fileserver for the local network (”/etc/puppet/fileserver.conf”):

path /etc/puppet/files
allow *.domain.local

path /etc/puppet/files
allow *.domain.local

Note:You can allow a subnet, too. (”allow”).

Edit / Create the site file ”/etc/puppet/manifests/site.pp”:

This is puppets main configuration file. To test the configuration, we want to copy a file from the puppetmaster to the clients.

# site.pp

class filetest {
   file { '/etc/testfile':
      source => "puppet://puppetmaster.domain.local/files/etc/testfile"

node default {
   include filetest

Now create the testfile and the directories:

mkdir -p /etc/puppet/files/etc
vim /etc/puppet/files/etc/testfile

Choose a content for this file “Hello World” for example.

/etc/init.d/puppetmaster restart

Client Installation

aptitude install puppet

Connect the puppet client to the server

Add the following content to the puppet configuration file /etc/puppet/puppet.conf to connect the client to the server.

/etc/init.d/puppet restart

On the puppetmaster:

puppetca --list
puppetca --sign pc1.domain.local

A restart of puppet is the fastet way to test the configuration:

/etc/init.d/puppet restart

Now you should see the file /etc/testfile on each client.

In the next part of this howto, we will use some modules with puppet and create an example configuration for pratical use.
