Cloud Provisioner on Centos

[PuppetUser]

Hi,

 

I am using Amazon Linux 3.2 ec2 instance to install puppet master.

I used puppet-server install command.

Installation is done.

When i use sudo vim /etc/puppet/puppet.conf.. I see only [main] and [agent] blocks. I dont see [master] block.

My doubt is whether master get installed or not ??

 

I have installed cloud-provisioner using puppet module tool. I should move the lib directory of cloud-provisioner to :$RUBYLIB manually because export RUBYLIB=/etc/puppet/modules/cloud_provisioner/lib:$RUBYLIB did not work for me. Please give me the steps of exporting manually because i am new to unix environment.

 

Thanks and Regards

 

Srinivas.

Hi,

 

I need to describe dependencies between nodes, for example, to be sure that database is deployed on one node before deploying web application on another node.

 

This link http://grokbase.com/t/gg/puppet-users/127svph7e0/how-to-acgieve-inter-node-dependencies-with-puppet explain that MCollective is needed for that.

 

Is it true ? Do I need to install MCollective to define dependencies between node ?

I haven't messed with inter-dependent nodes yet, but exported resources
might fit the bill. Something like:

,----
| node a {
| # Do this when the DB is installed
| @@file { "/tmp/dbdone.txt": content => "Woo, DB installed!\n", tag => "dbdone", }
| }
|
| node b {
| File <<| tag == 'foofile' |>>
| }
`----


Then if /tmp/dbdone.txt is on nodeb it's safe to install? Again,
haven't tried this but potentially worth looking at. No matter what I'm
curious what the solution is.

I agree with Kyle.

This seems like the best way to achieve this sort of node interdependence. 

,----
| node a {
|     # Do this when the DB is installed
|     @@file { "/tmp/dbdone.txt": content => "Woo, DB installed!\n", tag => "dbdone", }
| }
|
| node b {
|     File <<| tag == 'foofile' |>>
| }
`----

haven't tried this but potentially worth looking at.  No matter what I'm
curious what the solution is.

Hi,

Thanks for the answer, I understand that with exported resources, I can create interactions between nodes.

But If I understood your suggestion, on node b I will get the file defined on node a : great.

But does this implicitly mean that all resources on node b will wait that the file is created ? Or how do I define a require link between the classes define on node b ?

May I write something like that :

node a {
# Do this when the DB is installed
@@file { "/tmp/dbdone.txt": content => "Woo, DB installed!\n", tag
=> "dbdone", }
}

node b {

File <<| tag == dbdone |>>

Pakackage{'jboss':
require => [ File<<| tag == dbdone |>>],

}
}

Hi,

Anothoer point about dependencies between nodes, is it possible to say that an exported resources requires another one ?

If I used the example given by kyle :

node a {
# Do this when the DB is installed
@@file { "/tmp/dbdone.txt": content => "Woo, DB installed!\n", tag => "dbdone", } }

node b {

File <<| tag == dbdone |>>

Pakackage{'jboss':
require => [ File<<| tag == dbdone |>>], } }

I want to export the resource file only if db installation success otherwise not.

Hi,

 

To use exported ressources, I choice to install mysql and I modify puppet.conf, adding :

    storeconfigs = true

    dbadapter = mysql

    dbuser = puppet

   dbpassword = <<a password>>

    dbserver = localhost

    dbsocket = /var/run/mysqld/mysqld.sock

 

Then I run : /etc/init.d/puppetmaster restart

 

And on client I have the following error :

Warning: Error 400 on SERVER: Could not retrieve facts for <<agent fqdn>>: Could not autoload puppet/indirector/facts/active_record: uninitialized constant ActiveRecord

 

Does some one knows what’s happened ?
