linux 值安装yum包

1、 创建文件，挂载  rhel7-repo-iso

[root@rhel7 ~]# mkdir /media/rhel7-repo-iso
[root@rhel7 ~]# mount /dev/cdrom /media/rhel7-repo-iso/
mount: /dev/sr0 is write-protected, mounting read-only

2、yum文件引入挂载点

[root@rhel7 ~]# vi /etc/yum.repos.d/RHEL_7_Disc.repo
[root@rhel7 ~]# cat /etc/yum.repos.d/RHEL_7_Disc.repo
[RHEL_7_Disc]
name=RHEL_7_x86_64_Disc
baseurl="file:///media/rhel7-repo-iso/"
gpgcheck=

3、列出yum
