Question

根据每当文档可以指定一组never_roles（https://github.com/javan/whenever#capistrano-roles）。现在我想在schedule.rb中定义一组cronjobs，并根据它们的角色划分它们，如下所示：

set :output, "log/cron.log"

every :day, at: '11:00', roles: :whenever_alt do
  runner 'MySuperScriptClass1.start'
end

every :day, at: '12:30', roles: :whenever_main do
  runner 'MySuperScriptClass2.start'
end

部署文件

set :whenever_roles, ["whenever_main", "whenever_alt"]

关于production.rb

role :whenever_main,  %w{ip_address_1}
role :whenever_alt,   %w{ip_address_2}

问题在于，当我使用该配置部署capistrano时，我得到了

cap aborted!
undefined method `to_sym' for [:whenever_main, :whenever_alt]:Array

/Users/.../gems/whenever-0.9.0/lib/whenever/tasks/whenever.rake:4:in `block (2 levels) in <top (required)>'

如何在每个服务器上使用时间分隔一个cronjobs？

非常感谢

1）在schedule.rb中，将角色变为数组

every :day, at: '11:00', roles: [:whenever_alt] do # NOTE that ":whenever_alt" is now "[:whenever_alt]"
  runner 'MySuperScriptClass1.start'
end

every :day, at: '12:30', roles: [:whenever_main] do
  runner 'MySuperScriptClass2.start'
end

2）确保你的版本至少为0.9.1

每当gem指定运行每个作业的服务器时
