我对厨师来说是一次意想不到的经历。这是：

我宣布了我的安装 postgres 的方法。

execute 'sudo apt-get install postgresql-9.1 -y --force-yes'

template "/etc/postgres/9.1/main/pg_hba.conf" do
  source "pg_hba.conf.erb"
  owner "postgres"
  group "postgres"
  mode 00600
  notifies :restart, 'service[postgresql]', :immediately
  subcribes:
end

service "postgresql" do
  service_name "postgresql"
  supports :restart => true, :status => true, :reload => true
  action [:enable, :start]
end

但是当我跑到测试厨房收敛时。

我认为厨师在经过配方中的每个资源时运行资源。

但它向我展示了相反的情况。

厨师怎么样？

这里有几点。

首先，您粘贴的输出不是顶部的配方代码。它显示了在编译期间声明的action :nothing正在运行的资源，建议您执行以下操作：

execute 'sudo apt-get install postgresql-9.1 -y --force-yes' do
  action :nothing
end.run_action(:run)

我相信您在尝试解决订购问题时所做的事情（一开始就不存在）。

其次，Chef 完全按照您的预期执行，并按照您在配方中声明的顺序运行每个资源。如果您查看该Converging 3 resources行之后的日志，您会看到它使用 执行execute，action :nothing然后是template，最后是service.

您还可以在此之前看到，它execute在编译期间运行您的资源并且没有安装任何软件包，因为“ postgresql-9.1 is already the newest version”（也在日志中明确说明）。

第三点，您的配方可能会失败，因为该postgresql-9.1软件包没有创建您期望它创建的目录：“ Parent directory /etc/postgres/9.1/main does not exist”。

第四，安装包的惯用 Chef 方法是使用package资源：

package "postgresql-9.1" do
  action :install
end

我的建议：登录到您要部署此配方的机器，确保postgresql-9.1已安装软件包（如果未安装，则安装），确保这是您需要的软件包，然后找出pg_hba.conf文件所在的位置那个特定的操作系统。然后，修复您的template资源以指向正确的位置。
