Question

我一直是厨师的意外体验。这是：

我宣布我的食谱安装postgres。

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的时候。

我认为Chef在配方中的每一个都经过了资源。

但它让我反其道远。

厨师怎么样？

Answer 1

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运行action :nothing声明的资源，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（首先不存在）。

其次，Chef正在按照您的期望完成任务，并按照您在食谱中声明的顺序运行每个资源。如果您在Converging 3 resources行后查看日志，您会看到它execute与action :nothing一起执行，然后是template，最后是service }。

之前您还可以看到，它在编译期间运行了您的execute资源，并且没有安装任何软件包，因为＆＃34; postgresql-9.1 is already the newest version＆＃34; （也在日志中明确说明。）

第三点，你的食谱可能失败了，因为postgresql-9.1包没有创建你期望它的目录：＆＃34; Parent directory /etc/postgres/9.1/main does not exist＆＃34;。

第四，安装包的惯用厨师方法是使用package resource：

package "postgresql-9.1" do
  action :install
end

我的建议：登录您正在部署此配方的计算机，确保已安装postgresql-9.1软件包（如果不是，请安装它），请确保＆＃39; ; s您需要的包，然后找出pg_hba.conf文件在该特定操作系统中的位置。然后，修复您的template资源以指向正确的位置。

厨师运营其资源的顺序是什么？
