Hello Everybody,

I am trying to configure foreman for puppet 3.0. on centos 6.3

I have followed the instructions provided over here to install foreman:-

http://theforeman.org/projects/foreman/wiki/RPM's_distribution_based_installation

I have installed the following rpm:

http://yum.theforeman.org/development/el6/foreman-release.rpm

I have done the settings for the files in /etc/foreman as follows:-

settings.yaml has the following contents:

:puppet_server: puppet

:unattended: true

:puppetconfdir: /etc/puppet/puppet.conf

:login: false

:require_ssl: false

database.yaml has the following contents:

# SQLite version 3.x

# gem install sqlite3

development:

adapter: sqlite3

database: db/development.sqlite3

pool: 5

timeout: 5000

# Warning: The database defined as "test" will be erased and

# re-generated from your development database when you run "rake".

# Do not set this db to the same as development or production.

test:

adapter: sqlite3

database: db/test.sqlite3

pool: 5

timeout: 5000

#production:

# adapter: sqlite3

# database: db/production.sqlite3

# pool: 5

# timeout: 5000

production:

adapter: mysql

database: puppetdb

username: puppetdb

password: puppetdb

host: 10.12.14.107

socket: "/var/run/mysqld/mysqld.sock"

I am getting the following error when am trying to execute db:migrate command:

su - foreman -s /bin/bash -c /usr/share/foreman/extras/dbmigrate

It fails with the following error:

/usr/lib/ruby/gems/1.8/gems/ruby_parser-2.3.1/lib/ruby_parser_extras.rb:10: warning: already initialized constant ENC_NONE

When i tried to run it with trace option I get the following output:

Can anyone tell, what does this error means? Do we need to initialize the constant HostObserver?

If yes, how do we go about initliazing it?

Thanks,

Nishant

at the moment the stable version of foreman does not support puppet3.

You could give the current workaround patch a try at [1] and some more details at [2]

Thanks Ohad,

Got it working by applying the patch u suggested.

But again it was having error finding the value of $vardir and so have to specify it explicitly in /etc/puppet/puppet.conf and it got working.
