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 Loaded plugins: fastestmirror Loading mirror speeds from cached hostfile * base: mirrors.ustc.edu.cn * extras: mirrors.ustc.edu.cn * updates: mirrors.ustc.edu.cn WANdisco-git/7/x86_64/filelists_db | 172 kB 00:00:01 base/7/x86_64/filelists_db | 7.2 MB 00:00:01 extras/7/x86_64/filelists_db | 277 kB 00:00:00 updates/7/x86_64/filelists_db | 9.4 MB 00:00:01 32:bind-utils-9.11.4-26.P2.el7.x86_64 : Utilities for querying DNS name servers Repo : base Matched from: Filename : /usr/bin/nslookup 32:bind-utils-9.11.4-26.P2.el7_9.2.x86_64 : Utilities for querying DNS name servers Repo : updates Matched from: Filename : /usr/bin/nslookup 32:bind-utils-9.11.4-26.P2.el7_9.3.x86_64 : Utilities for querying DNS name servers Repo : updates Matched from: Filename : /usr/bin/nslookup 32:bind-utils-9.11.4-26.P2.el7_9.4.x86_64 : Utilities for querying DNS name servers Repo : updates Matched from: Filename : /usr/bin/nslookup 32:bind-utils-9.11.4-26.P2.el7_9.5.x86_64 : Utilities for querying DNS name servers Repo : updates Matched from: Filename : /usr/bin/nslookup 32:bind-utils-9.11.4-26.P2.el7_9.7.x86_64 : Utilities for querying DNS name servers Repo : updates Matched from: Filename : /usr/bin/nslookup 32:bind-utils-9.11.4-26.P2.el7_9.8.x86_64 : Utilities for querying DNS name servers Repo : updates Matched from: Filename : /usr/bin/nslookup 32:bind-utils-9.11.4-26.P2.el7_9.9.x86_64 : Utilities for querying DNS name servers Repo : updates Matched from: Filename : /usr/bin/nslookup [root@host1 golang]#
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
