2、mount /dev/cdrom /mnt/cdrom

3、取消挂载

3、进入目录rpm包的目录

cd cdrom

cd Packages

4、查询是否安装过git包

[root@yum-server Packages]# rpm -qa git
git-1.7.1-3.el6_4.1.x86_64 #已经安装，不需要再装，如果查不到结果，表示没有安装。

5、查看光盘中是否有应该软件包

[root@yum-server Packages]# find git*
git-1.7.1-3.el6_4.1.x86_64.rpm

6、安装该rpm包：

正常安装rpm包

[root@yum-server Packages]# rpm -ivh git*.rpm
Preparing... ########################################### [100%]
package git-1.7.1-3.el6_4.1.x86_64 is already installed

强制安装

[root@yum-server Packages]#rpm -ivhgit*.rpm--force

7、卸载rpm包：

rpm -e git

• 忽略依赖性删除

rpm -e git--nodeps

8、查看安装在什么位置

[root@yum-server Packages]# rpm -ql git
/etc/bash_completion.d
/etc/bash_completion.d/git
/usr/bin/git
/usr/bin/git-receive-pack
/usr/bin/git-shell
/usr/bin/git-upload-archive
/usr/bin/git-upload-pack
/usr/libexec/git-core
/usr/libexec/git-core/git
/usr/libexec/git-core/git-add
