2. Puppet
Távoli adminisztráció
Puppet is a cross platform framework enabling system administrators to perform common tasks using
code. The code can do a variety of tasks from installing new software, to checking file permissions,
or updating user accounts. Puppet is great not only during the initial installation of a system, but also
throughout the system's entire life cycle. In most circumstances puppet will be used in a client/server
configuration.
This section will cover installing and configuring puppet in a client/server configuration. This simple
example will demonstrate how to install Apache using Puppet.
2.1. Telepítés
To install puppet, in a terminal on the server enter:
sudo apt-get install puppetmaster
On the client machine, or machines, enter:
sudo apt-get install puppet
2.2. Beállítás
Prior to configuring puppet you may want to add a DNS CNAME record for puppet.example.com,
where example.com is your domain. By default puppet clients check DNS for puppet.example.com as
the puppet server name, or Puppet Master. See 7. fejezet - Tartománynév-szolgáltatás (DNS) [94]
for more DNS details.
If you do not wish to use DNS, you can add entries to the server and client /etc/hosts file. For
example, in the puppet server's /etc/hosts file add:
127.0.0.1 localhost.localdomain localhost puppet
192.168.1.17 meercat02.example.com meercat02
On each puppet client, add an entry for the server:
192.168.1.16 meercat.example.com meercat puppet
Replace the example IP addresses and domain names above with your actual server and
client addresses and domain names.
Now setup some resources for apache2. Create a file /etc/puppet/manifests/site.pp containing
the following:
package {
