我在我的ruby on rails app上实现了gem。这个gem生成了配置文件,我在那里有这样的数据:
配置/ schedule.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 cron_log.log 为空。为什么?我该如何解决这个问题?
