server to run cronjobs with the help of cpanel when it comes to
rackspace there is no cpanel .help me out guys..

thanks in advance

You can take a look at the whenever gem, it provides a nice way to manage cron jobs through ruby and if you are deploying using capistrano you just need to add this two lines to your deploy.rb file:

set :whenever_command, “bundle exec whenever”

require “whenever/capistrano”

Give it a try =D

Best regards!
