我在我的 ruby​​ on rails 应用程序中实现了 gem。这个 gem 生成的配置文件，我有这样的数据：

配置/时间表.rb

set :output, "/vol/www/apps/logs/cron_log.log"                                #Log for production.
set :my_path, "/vol/www/apps/ror_tutorial/current"

every 5.minutes do
  command "cd #{my_path} && bundle exec rake thinking_sphinx:index RAILS_ENV=production && bundle exec rake thinking_sphinx:rebuild RAILS_ENV=production && chmod 777 -R #{my_path}/log"
end

所以这会在 crontab 中生成这样的代码：

$ crontab -e

# Begin Whenever generated tasks for: ror_tutorial
0,5,10,15,20,25,30,35,40,45,50,55 * * * * /bin/bash -l -c 'cd /vol/www/apps/ror_tutorial/current && bundle exec rake thinking_sphinx:index RAILS_ENV=production && bundle exec rake thinking_sphinx:rebuild RAILS_ENV=production && chmod 777 -R /vol/www/apps/ror_tutorial/current/log >> /vol/www/apps/logs/cron_log.log 2>&1'

# End Whenever generated tasks for: ror_tutorial

Everuthing 有效，但我的cron_log.log为空。为什么？我该如何解决？

Check out where crond is being started. The logging level may be turned off. This post here explains it fairly well.
