作业五：rpm命令
1) 挂载光盘文件到/media目录
[root@localhost 桌面]# mount /dev/sr0 /media
mount: /dev/sr0 写保护，将以只读方式挂载
[root@localhost 桌面]# df
文件系统 1K-块 已用 可用 已用% 挂载点
/dev/sda3 18351104 3495804 14855300 20% /

/dev/sr0 4050860 4050860 0 100% /media
[root@localhost 桌面]#
2) 进去/media目录下的Packages目录
[root@localhost 桌面]# cd /media
[root@localhost media]# ls
CentOS_BuildTag GPL LiveOS RPM-GPG-KEY-CentOS-7
EFI images Packages RPM-GPG-KEY-CentOS-Testing-7
EULA isolinux repodata TRANS.TBL
[root@localhost media]# cd Packages
3) 查看系统已安装的所有rpm包
[root@localhost Packages]# rpm -qa
4) 查看系统是否安装dhcp软件包
[root@localhost Packages]# rpm -qa |grep dhcp
dhcp-common-4.2.5-27.el7.centos.x86_64
dhcp-libs-4.2.5-27.el7.centos.x86_64
[root@localhost Packages]# rpm -q dhcp
未安装软件包 dhcp
5) 安装dhcp软件包
[root@localhost Packages]# rpm -ivh dhcp-4.2.5-27.el7.centos.x86_64.rpm
警告：dhcp-4.2.5-27.el7.centos.x86_64.rpm: 头V3 RSA/SHA256 Signature, 密钥 ID f4a80eb5: NOKEY

Summary : Dynamic host configuration protocol software
Description :
DHCP (Dynamic Host Configuration Protocol) is a protocol which allows
individual devices on an IP network to get their own network
configuration information (IP address, subnetmask, broadcast address,
etc.) from a DHCP server. The overall purpose of DHCP is to make it
easier to administer a large network.
To use DHCP on your network, install a DHCP service (or relay agent),
and on clients run a DHCP client daemon. The dhcp package provides
the ISC DHCP service and relay agent.
