On the file:
/config/application.rb
set the current configuration:
# Roteate logs when it is 100MB in size and keep 5. config.logger = Logger.new(Rails.root.join('log', "#{Rails.env}.log"), 5, 104857600)
This will automatically create files like
- development.log.0
- development.log.1
- etc…
Based on your environment
