Thanks Matthew . I removed the ruby block and much of what others said made sense :-),

Thanks,

Hey Ram,

So, there are two to three things wrong with your code:

1. svc is a variable and shouldn’t be wrapped in quotes, as others have mentioned.
2. require takes a string, not a class, which is the error you’re getting. This line isn’t necessary at all, though; you can probably just remove it. If you need to explicitly specify a provider for your services, use the provider attribute as Tensibai suggested.
3. If your /root/svc file already contains the required contents at the start of the chef run, then there’s no need to complicate things by using a ruby_block resource. You really only need a ruby_block if some other chef resource is going to be dropping off that file and you want to wait to read the contents until as late as possible.

I’m pretty sure what you want is something like this:

services = File.readlines("/root/svc")

services.each do |svc|
    service svc.chomp do
        provider Chef::Provider::Service::Init::Redhat  #This may not be necessary
        action [ :stop, :disable]
    end
end

I added the .chomp because the results of File.readlines appear to have new-lines on the end of them. I’m not 100% sure it’s required, but it won’t hurt.

You might want to consider reading over this for a quick overview of ruby for chef users.

Hope that helps.

Hi Tensibai,

I have tried "svc" , svc , "#{svc}" - nothing worked . Basically the contents of the file is as below which leaves scope for adding more services as required ,

cat /root/svc
auditd
vsftpd

Use the provider attribute if the service resource and your declaration should use the var without quotes or with #{svc}

See http://docs.getchef.com/resource_service.html for the service resource and provider attribute

If it is inside a recipe you don't have to require the service provider, it will guess it.
If you really want to enforce it, there's a provider attribute to the service resource.

For the error message, require take a path to a file without the extension, here it should be require "chef/provider/service/init/redhat"
