我目前正在使用 chef 来安装 RPM JDK 包，但问题是即使已经下载并安装了包，它每次都会这样做。我尝试在安装前找到一个检查选项，但没有。有没有办法解决这个问题，我可以跳过已经安装的包？Debian 的包管理默认会跳过已安装的包，但 RPM 包管理器似乎没有这样做。

我知道这是旧的，但我相信你想要：

remote_file "your-remote-file" do
  ...
  not_if "rpm -qa | grep -qx 'your-package'"
end

我对 RPM 不熟悉，但您可以查看Chef 如何了解软件包是否已安装（load_current_resource 方法）。你可以在你的配方中实现类似的东西，并将这个条件添加到 remote_file：

remote_file "#{Chef::Config[:file_cache_path]}/#{javaRPM}" do
  not_if { [your_code_that_checks_if_package_installed] }
  ...
end

Chef 为rpm_packages提供了资源。你可以找到很多例子来展示厨师如何验证是否安装了一个包

您可以先删除软件包使用ignore_failure然后安装它

package 'package_name'
  ignore_failure true
  action         :remove
end

然后抓取文件

remote_file localPath do
    source packageUrl
    mode 0644
    checksum checkSum
end

然后安装包

package packageName do
      source localPath
      action :install
      allow_downgrade true
end

这适用于任何包类型。理想情况下，对于 rpm，您不需要删除该软件包。allow_downgrade应该管用。但这对我不起作用。

用于校验和curl packageUrl | shasum -a 256

not_if还有另一种方法，请参见下面的示例

execute 'yum -y install ntp' do
  not_if "rpm -qa | grep 'ntp'"
end
