最简单的方法是

RAILS_DEFAULT_LOGGER = Logger.new("#{RAILS_ROOT}/log/#{RAILS_ENV}.log", "daily")

实际上Rails做了一些优化，通过ActiveSupport::BufferedLogger来提高产品环境下的性能。所以比较好的做法是在config/environment.rb加入如下代码：

   config.logger = begin
        path = config.paths.log.to_a.first
        logger = ActiveSupport::BufferedLogger.new(path, "daily")
        logger.level = ActiveSupport::BufferedLogger.const_get(config.log_level.to_s.upcase)
        logger.auto_flushing = false if Rails.env.production?
        logger
    rescue StandardError => e
        logger = ActiveSupport::BufferedLogger.new(STDERR)
        logger.level = ActiveSupport::BufferedLogger::WARN
        logger.warn(
            "Rails Error: Unable to access log file. Please ensure that #{path} exists and is chmod 0666. " +
            "The log level has been raised to WARN and the output directed to STDERR until the problem is fixed."
        )
        logger
    end
