即使我在一个盒子上运行 chef-client，它也会等待大约 5 分钟来下载 JDK，即使它之前已经完成了。有什么办法可以解决这个问题吗？

[Mon, 22 Oct 2012 13:17:46 -0500] INFO: Processing remote_file[/var/chef/cache/jdk-1.6-u30-linux-amd64.rpm] action create_if_missing (sun_java::default line 18)

配方如下：

urlVersion = "1."+node["sun_java"]["version"].sub(/[u]/, "-u")
node.default["sun_java"]["rpm_url"] = "http://***/#{urlVersion}/jdk-#{urlVersion}-linux-#{node["sun_java"]["arch"]}.rpm"

#Check that we are using the .rpm file because of the recent change
if File.extname(File.basename(node["sun_java"]["rpm_url"]))!=".rpm"
  raise "You must use the jdk*.rpm file to install the Sun JDK. You can get it from the jdk*-rpm.bin file by running the command './jdk*-rpm.bin -x'"
end

javaRPM = File.basename(node["sun_java"]["rpm_url"])

remote_file "#{Chef::Config[:file_cache_path]}/#{javaRPM}" do
  action :create_if_missing
  source node["sun_java"]["rpm_url"]
  mode "0755"
  backup false
end

package javaRPM do
  action :install
  source "#{Chef::Config[:file_cache_path]}/#{javaRPM}"
  options "--nogpgcheck" # sun/oracle doesn't sign their RPMs o_O
  notifies :run, "bash[update-alternatives java]", :immediately
end

javaHomeFolder = "/usr/java/jdk1.#{node["sun_java"]["version"].sub(/[u]/, ".0_")}"
jdkFolder = "#{javaHomeFolder}/bin"
slaveString = ""

node["sun_java"]["update_slaves"].each do |java_bin|
  slaveString = slaveString + "--slave \"/usr/bin/#{java_bin}\" \"#{java_bin}\" \"#{jdkFolder}/#{java_bin}\" "
end

bash "update-alternatives java" do
  action :nothing
  code <<-EOH
    update-alternatives --install "/usr/bin/java" "java" "#{jdkFolder}/java" 1 #{slaveString}
    update-alternatives --set java #{jdkFolder}/java
  EOH
end

#Remove old environment then notify new environment to be created
ruby_block "delete_environement" do
        block do
            editBashrc = Chef::Util::FileEdit.new("/etc/profile")
                editBashrc.search_file_delete_line(/^.*#JAVA_HOME environment settings.*$/)
                editBashrc.search_file_delete_line(/^.*#Auto-generated by Chef Cookbook sun_java.*$/)
                editBashrc.search_file_delete_line(/^.*export JAVA_HOME=.*$/)

不是下载需要 5 分钟。似乎 rpm 每次都重新安装软件包（输出缩短并注释）：

[Mon, 22 Oct 2012 13:17:46 -0500] Processing remote_file # Download the file
[Mon, 22 Oct 2012 13:17:48 -0500] Processing package # Install the file 2 secs later
[Mon, 22 Oct 2012 13:21:07 -0500] package installed # 3+ minutes later

我不知道rpm，但 Debian 的包管理默认会跳过已安装的包。

所以我想你的选择是：

  1. 将 chef 配置为更详细。这样，您可以使用所有选项跟踪调用，并查看是否通过从 shell 运行相同的命令来重新产生行为。
  2. 查明rpm其行为是否与 Debian 相同dpkg（见上文）。如果没有，告诉它跳过已经安装的包。
  3. 检查软件包版本。如果您的包版本在每次运行时都相同，请转到 (1)。如果不是，请查看是否可以rpm跳过类似版本。
  4. 不要使用package资源，而是手动安装包（仅在所有其他选项都失败时使用）。例如，您可以使用该execute资源并创建一个指示文件，告诉 Chef 您已经安装了该软件包。

选项 #4 的伪代码：

execute "install Java by hand" do
  command "rpm install <pkg> && touch /home/user/java_installed"
  creates "/home/user/java_installed"
end
