场景
当我们希望安装 wget 命令,而包的名字也是wget,这时使用yum install wget即可,很多软件安装包均是如此。但也有很多不同,比如 nslookup 命令所在的包就是 bind-utils ,安装包名就不同,实际上 yum 提供了很多命令可以进行搜索,比如 yum provides 或者 yum whatprovides。
yum provides 和 yum whatprovides 很类似,因此这里只介绍 yum provides。
查询 nslookup 所在的安装包:
[root@host1 golang]# yum provides nslookup

可以看到,nslookup 命令在 bind-utils 包中,因此需要使用 nslookup 命令就得安装 bind-utils 包:
yum install -y bind-utils
