在日常运维工作中，我们发现某个常用命令（比如rz，sz）不存在，这时需要手动yum安装这个命令，但是又想不起来这个工具包的名称，肿么办？？
这种情况下，我们可以使用yum search去yum源里搜索，搜索出来后就可以直接yum安装了
比如，系统最小化安装后，发现没有telnet，rz，sz，rsync命令
如下，yum serach搜索下：
[root@openstack-server ~]# yum search telnet
Loaded plugins: fastestmirror
Loading mirror speeds from cached hostfile
* base: mirrors.aliyun.com
* extras: ftp.sjtu.edu.cn
* updates: mirrors.aliyun.com
============================================================= N/S matched: telnet =============================================================
perl-Net-Telnet.noarch : Net-Telnet Perl module
telnet.x86_64 : The client program for the Telnet remote login protocol
telnet-server.x86_64 : The server program for the Telnet remote login protocol
tn5250.i686 : 5250 Telnet protocol and Terminal
tn5250.x86_64 : 5250 Telnet protocol and Terminal
Name and summary matches only, use "search all" for everything.
如上，可以yum insyall telnet-server安装telnet
[root@openstack-server ~]# yum search rz

如上，可以yum insyall lrzsz安装rz、sz
