I'm going to assume by /lib you mean RAILS_ROOT/lib ...

I'll assume app_root == RAILS_ROOT. So, you created a "daemon" directory in
the root of your rails app then and placed myserver.rb in it.
Okay, if you'll be running it manually (not in the context of rails via
rails runner) then your options are:
1. relative path for require statement in myserver.rb: require
'../lib/my_module'
2. an "expand_path"-style relative require statement: require
File.expand_path('../../lib/my_module', __FILE__)
3. update the load path then require:
$:.unshift(File.expand_path('../../lib', __FILE__) ; require 'my_module'
4. ... many many variations on the above.
If you _are_ running by using "rails runner daemon/myserver.rb" then the
RAILS_ROOT/lib directory should already be in your load path. You can just:
require 'my_module' and be fine.
