“yum -y install nfs-utils nfs-utils-lib”在 CentOS vagrant 机器上安装 NFS 客户端时

【中文标题】“yum -y install nfs-utils nfs-utils-lib”在 CentOS vagrant 机器上安装 NFS 客户端时【英文标题】："yum -y install nfs-utils nfs-utils-lib" when installing NFS client on a CentOS vagrant machine 【发布时间】：2017-01-01 18:17:52 【问题描述】：我试图“流浪”一台 CentOS 机器 (centos7-x64-vbox43)，VirtualBox 作为提供者，ansible 作为配置工具。我执行了以下命令：
vagrant up --provision-with ansible
但是我得到一个错误，这与在guest机器中执行以下命令yum -y install nfs-utils nfs-utils-lib有关（我猜）：
[project-name] > vagrant up

Error Summary
-------------
我不知道为什么会这样，因为我对vagrant 不是很熟悉，可以说我已经使用了两次或三次。我的第一个问题是：为什么会发生这种情况？
注意，我想我知道 NFS 是什么，即它应该是安装在客户机上的文件系统，它允许同一台机器和主机共享文件夹和文件，对吧？
在找到以下文章之前，我无法解决这个问题：
yum update or yum install fails with package conflict between 64 bit and 32 bit package architectures?
至少对我而言，其标题似乎与上述问题完全无关。
我意识到上面的命令失败后，vagrant机器实际上已经初始化了，我可以使用vagrant ssh连接到它，这就是我所做的。然后，在访客 vagrant 机器中（在vagrant ssh 之后），我执行了以下命令（与我刚刚提到的文章中指定的命令相同）：
sudo yum install yum-utils
sudo package-cleanup --dupes
sudo package-cleanup --cleandupes
添加了这一行：
exactarch=1
到文件/etc/yum.conf，最后
yum clean all
sudo yum update
我通过输入exit 退出了流浪机器。我做了vagrant halt 来停止机器。我重新执行了初始命令：
vagrant up --provision-with ansible
并且错误不再发生。
我的第二个问题是：为什么执行上面教程中的命令以及我在上面明确提到的命令可以解决问题？
执行删除重复包的命令时，我注意到输出是，实际上没有重复包。就我而言，似乎唯一真正解决问题的命令是（不确定）：
yum clean all
sudo yum update
为什么这实际上可以解决问题？
我的一个想法是这个盒子实际上已经过时了，因为将预安装的软件包更新到最新版本显然解决了这个问题......
【问题讨论】：
【参考方案1】：很遗憾，您输入的命令可能已经解决了一些不同的问题，而原始安装并没有提供太多信息。
可能是原始图像的包中存在阻止此安装的错误，但sudo yum update 通过安装更新的包修复了该问题。
也有可能是 yum 数据库已损坏并且它没有安装 nfs-utils 或 nfs-utils-lib 的先决条件，因为它认为它们已经安装，但“清理”修复了 yum 数据库。
关于 package-cleanup 的 Dito，它位于 yum-utils 内部。
exactarch=1 可能没有解决任何问题，因为您没有在任何地方指定特定架构（假设原始图像也没有）。
听起来您在问题结束时已经很清楚了。还有什么？
【讨论】：
【参考方案2】：CentOS 7 中有一个bug - 导致此错误的软件包：
仅更新 device-mapper 子包而不更新 lvm2 包时，如果在子包中移动文件，我们可能会遇到文件冲突。 ...为避免从旧版本更新时出现问题，现在在软件包中明确定义了直接冲突，如果命中，将提供有关解决此冲突所需的最低版本的信息。
因此，更新lvm2 是一种解决方案。我认为yum update 解决了这个问题，因为添加到包中的冲突是作为包信息的一部分从包存储库加载的。因此，lvm2 可能在 Vagrant 安装 device-mapper 时已更新，此更新避免了该错误。
【讨论】：
相关问题：***.com/questions/36439746/…。在我看来，我无法链接这些问题。是否可以手动添加链接？以上是关于“yum -y install nfs-utils nfs-utils-lib”在 CentOS vagrant 机器上安装 NFS 客户端时的主要内容，如果未能解决你的问题，请参考以下文章
