CentOS下安装 lspci 当 yum install 软件 无法安装的时候 找不到安装包的时候whatprocides 什么提供 有大用 有大大用 有大大大用
CentOS下安装lspci
在CentOS的最小化安装中，默认是不会安装lspci工具的，需要自己手动安装。
安装步骤：1、yum whatprovides */lspci /* 查找lspci是通过哪个安装包来提供的
2、yum install pciutils
完成安装！

[root@localhost yum.repos.d]# yum provides lspci
Loaded plugins: product-id, security, subscription-manager
This system is not registered to Red Hat Subscription Management. You can use subscription-manager to register.
Warning: 3.0.x versions of yum would erroneously match against filenames.
You can use "*/lspci" and/or "*bin/lspci" to get that behaviour

由于一向最小安装，有时不记得某些命令是在哪个安装包中，现写出来方便查找：命令：yum whatprovides */命令名
比如查找pvcreate是哪个安装包提供的：
yum whatprovides */pvcreate
结果显示：[root@iTarget ~]# yum provides */pvcreate

我们可以加上参数provides来查询nslookup在那个套件中
yum provides nslookup
Loaded plugins: fastestmirror
Repository base is listed more than once in the configuration
Repository updates is listed more than once in the configuration
Repository extras is listed more than once in the configuration
Repository centosplus is listed more than once in the configuration

虽然没有查询到，但是还是查存在在bin下面。所以依旧利用参数provides来查询
yum provides *bin/nslookup

Repository extras is listed more than once in the configuration

Matched from:
Filename : /usr/bin/nslookup
此时发现nslookup属于bind-utils，继续使用yum安装即可
yum install bind-utils
即可完成安装。
注：命令dig与host也是在该套件中。
