Puppet users - Nov 2008 - System configuration and /etc/init.d/* deamons

Hi,

I wish to update some files, like for example /etc/ntp.conf (or others
like this)... and restart daemons if the file has being updated.

I''am able to send the file.... with the following class :

# NTP
class ntpconf {
        case $operatingsystem {

        "RedHat": {
                file { "/etc/ntp.conf" :
                        path => "/etc/ntp.conf",
                        mode => 0644,
                        owner => root,
                        group => root,
                        content => template("ntp.conf.rh.erb");
                }

        }

        }
}

One thing I miss is how to do /etc/init.d/ntp restart when the file is
modified, but *only* if the file is modified (not every time the check
has been done....) ?

Thanks
/Xavier

you have then to manage the ntp-service and use the notify in the file
definition for this service.

have a look at the documentation on the wikis. this very default example
is covered in various places.

Hum... Yes, but I didn''t yet understood how to "manage the ntp-
service"...

Sorry about this newbee question, but I''m still a bit puzzled about
that... Or if you have a good and simple example pointer I will be
please to check and see that on myself.

Thanks,

by using the service type:

The best thing is that you go through the docu on the wiki. There are a
lot of different examples how you can do different stuff.

A good example for your current need is:
http://reductivelabs.com/trac/puppet/wiki/Recipes/Monit

There is even an example for OpenNTPD:
http://reductivelabs.com/trac/puppet/wiki/Recipes/OpenNTPD

but to start this might look a bit complicated, but after reading some
docu and getting used to puppet, you''ll see what it is doing.

There are other ntp examples as well:
http://git.black.co.at/?p=module-ntp or
http://github.com/puzzle/puppet-ntp/tree/master
