niraj.kumar · 02-15-2010, 05:21 AM

Dear All,

I have installed a puppet server and its client on Centos.
Puppet server and its client is running fine and its
update whatever changes made on Puppet server is updated
on its client but i am unable to execute script (Bash shell)
on the client through Puppet server. So please advice
a suitable class or parameter for Puppet server so that
it could execute on its client.

Any help would be appreciable.........

Thanks,
Niraj

May be it is too late. But still I also got stuck in it for some time.

Here is the solution

Code:

 
# vi /etc/puppet/manifests/nodes.pp
...
...
class test1 {
exec { "/path/of/script": }
}
 
node box2 {
    include "test1"
}

Run, the below command on Puppet Client i.e. box2 in my case.

Code:

 
puppetd --test --server=box1.test.com

I have box1.test.com as Puppet Server
and
box2.test.com as Puppet Client.

Hi Bhaskar,

Assuming you have installed it properly download this tar.gz file and put it in /etc folder.

First, unzip it and then untar it.

Also, do this if you have installed from source files.

Code:

groupadd puppet  
useradd -g puppet puppet 
chown -R puppet.puppet /var/lib/puppet

Then,

Code:

cp -p /etc/puppet/manifests/nodes.pp /etc/puppet/manifests/nodes.pp_orig
> /etc/puppet/manifests/nodes.pp
cat /etc/puppet/manifests/nodes.pp
class test1 {
exec { "/bin/echo hello > /tmp/vikas": }
exec { "/bin/echo vikas >> /tmp/vikas": }
}
node box1 {             ## Assuming your machine name is box1
    include "test1"
}

Finally, you can start you puppet as below

Code:

# service puppetmaster stop
# /usr/sbin/puppetmasterd --logdest console
# /usr/sbin/puppetd --server box1.test.com --verbose --waitforcert 30
# /usr/sbin/puppetca --list
box1.test.com       --- you should see your system hostname here.
/usr/sbin/puppetca --sign box1.test.com

To check if all worked well, try below command

Code:

puppetd --test --server=box1.test.com --debug

This should create a file /tmp/vikas

Try this and get back if you still face problems.
