1. 序言
如筆者在本機上運行netstat時，提示沒有這個命令，向來簡單粗暴，直接yum -y install netstat，顯然是不能正常安裝的。
[root@hadoop-103 ~]# yum -y install netstat
Loaded plugins: fastestmirror
Determining fastest mirrors

No package netstat available.
Error: Nothing to do
[root@hadoop-103 ~]#
這種情況下，怎么辦呢？
2. 使用“yum search”命令
此時可以使用“yum search”來查詢這個命令在哪個包中：
[root@hadoop-103 ~]$ yum search netstat
Loaded plugins: fastestmirror
Repodata is over 2 weeks old. Install yum-cron? Or run: yum makecache fast
Loading mirror speeds from cached hostfile

dstat.noarch : Versatile resource statistics tool
net-snmp.x86_64 : A collection of SNMP protocol tools and libraries
net-tools.x86_64 : Basic networking tools #這里已經給出了netstat命令所在包
接着直接安裝這個包即可：yum -y install net-tools
3.使用“yum whatprovides ”查詢命令所在的包
還可以使用yum whatprovides
[root@hadoop-103 ~]# yum whatprovides *netstat
Loaded plugins: fastestmirror

* base: mirrors.aliyun.com
* extras: mirrors.aliyun.com
* updates: mirrors.aliyun.com
