tomcat - 用 Chef 部署war文件后如何重启tomcat？

Question

我有自己的 Recipe ，它从 AWS S3 存储桶下载文件并尝试重启 tomcat 服务。

我正在使用来自 https://github.com/opscode-cookbooks/tomcat

的“官方”Tomcat 配方

FILE: myapp/recipes/default.rb

include_recipe 's3_file'
include_recipe 'tomcat::default'

s3_file "/var/lib/tomcat6/webapps/ROOT.war" do
    remote_path node['myapp']['packages_s3_bucket_path'] + 'myapp.war'
    bucket node['myapp']['packages_s3_bucket']
    aws_access_key_id node['myapp']['packages_s3_bucket_aws_access_key']
    aws_secret_access_key node['myapp']['packages_s3_bucket_aws_secret_key']
    notifies :restart, "service[tomcat]", :immediately
end

问题是编译时没有找到service[tomcat](myapp的metadata.rb中也引用了tomcat)

有什么想法吗？谢谢

假设您正在使用默认设置中的基础实例，那应该是 service[tomcat6]。服务资源为defined inside the LWRP .这只有效，因为提供不 use_inline_resources，所以在未来的某个时候，这可能不再有效。

编辑:

我在下面提到的 hack。

ruby_block 'restart tomcat' do
  action :nothing
  block do
    resources('service[tomcat6]').run_action(:restart)
  end
end

或类似的东西。通知 ruby​​ block ，它会查找真正的资源并重新启动它。
