Answer 1

我认为您的问题是由于您在通知和订阅属性中使用：immediate 。

当您使用：立即时，立即运行通知，这在某些情况下是有意义的，但在这种情况下，您通知的资源或您订阅的资源可能尚不存在厨师执行执行。

默认情况下，notifications are是：delayed ，这意味着它们排队等待触发，并在Chef运行结束时执行。然后，它们可以传递到您要通知的services和其他资源。

对于上面的例子，我会修改如下内容：

template "/etc/supervisord.conf" do
 path "/etc/supervisord.conf"
 source "supervisord.conf.erb"
 owner "root"
 group "root"
 mode "0600"
 notifies :reload, "service[supervisord]", :delayed
end

template "/etc/init.d/supervisord" do
 path "/etc/init.d/supervisord"
 source "supervisord.erb"
 owner "root"
 group "root"
 mode "0755"
 notifies :reload, "service[supervisord]", :delayed
end

service "supervisord" do
 supports :restart => true, :start => true, :stop => true, :reload => true
 action :enable
end

以上代码执行以下操作：

创建supervisord配置文件，然后通知supervisord在Chef运行结束时重新加载
创建supervisord init.d脚本，然后通知supervisord在Chef运行结束时重新加载
声明supervisord服务资源，支持重启，启动，停止和重新加载，并在任何运行之后启用它
