Puppet users - Sep 2010 - Using FACTER in other ruby code

Hi all,

I''m trying to write a ruby script to setup MySQL replication base on
facts that we can distribute at runtime.

I have two facts(mysql_master and mysql_repl_dbs) that show up when I
run facter --puppet, however they do not appear to be imported in the
following script:

================================
#!/usr/bin/ruby
#
# mysql-replication.rb
#
# This script uses facter to setup mysql replication based upon the
facts mysql_master and mysql_repl_dbs
#
# It is currently in beta
#


# 1) Require the relevant libraries
require ''rubygems''
require ''facter''
require ''mysql''

# 2) Get the relevant facts and echo them to the screen
puts "Getting facts"
begin
        Facter.mysql_master
        puts "Facts received"
rescue
        Facter.loadfacts()
        puts "running rescue"
end

mysql_master = Facter.value(''mysql_master'')
mysql_repl_dbs = Facter.value(''mysql_master'')

puts "Master Server: #{mysql_master}\nDatabases: #{mysql_repl_dbs}"


=================
The output from the script is as follows:

Getting facts
running rescue
Master Server:
Databases:


where as facter --puppet mysql_master shows the correct hostname.

Am I missing a trick here?

Thanks,

Matt

add around here:

ENV[''FACTERLIB''] =
"/var/lib/puppet/lib/facter:/var/lib/puppet/facts"

substitute with wherever your pluginsync is putting the facts

Works a treat. (as always!)

Thanks for the heads-up.

How do I get this into the puppet/facter documentation?

not sure where would be appropriate, I just got that from the facter code -
looked what it does for --puppet :)

Did you ever get puppet to automate replication between a master mysql db 
and a slave mysql db. For example my host for the master is db01.xxx.xxx 
and the slave is db01.xxx.xxx. This seems to be an issue Puppet Labs does 
not support. Once I get a working solution I would like to present a 
presentation to San Francisco Puppet Master''s group as a demo to spread
the
knowledge. Thanks

Mac
