YUM是在Fedora和RedHat以及SUSE中基于rpm的软件包管理器，它可以使系统管理人员交互和自动化地更细与管理RPM软件包，能够从指定的服务器自动下载RPM包并且安装，可以自动处理依赖性关系，并且一次安装所有依赖的软体包，无须繁琐地一次次下载、安装。

RHEL7中的RedHat的YUM需要注册付费才能使用，本文简单介绍一下使用iso镜像文件建立本地YUM源；

Step1：上传RHEL7的镜像文件到/iso目录；

[root@rhel7-01

~]# cd /iso

[root@rhel7-01

iso]# ls -l

total 3948548

-rw-r--r--. 1

root root 4043309056 Feb 25 20:46 rhel-server-7.2-x86_64-dvd.iso

[root@rhel7-01

iso]#

Step2：mount这个iso文件到/mnt/iso目录；

[root@rhel7-01

~]# mount /iso/rhel-server-7.2-x86_64-dvd.iso /mnt/iso

mount:

/dev/loop0 is write-protected, mounting read-only

[root@rhel7-01

~]#

Step3：新建repo文件；

[root@rhel7-01 ~]# cd /etc

[root@rhel7-01 etc]# cd yum.repos.d/

[root@rhel7-01 yum.repos.d]# vim rhel7_local.repo

Step4：编辑repo文件，指定YUM路径；

[rhel7_local]

name =

rhel7_local

baseurl =

file:///mnt/iso

enable = 1

gpgcheck = 0

Step5：建立YUM缓存数据库，加快后续软件安装速度；

[root@rhel7-01

~]# yum makecache

langpacks, product-id, search-disabled-repos, subscription-manager

Created

Step6：编辑fstab，实现开机自动mount；

[root@rhel7-01

~]# cd /etc

[root@rhel7-01

etc]# vim fstab

Step7：添加最后一行内容，开机自动mount，需要指明iso9660文件类型；

/iso/rhel-server-7.2-x86_64-dvd.iso/mnt/iso iso9660 defaults0 0

Step8：确认fstab有效性和正确性；

[root@rhel7-01

~]# mount -a

[root@rhel7-01

~]# mount | grep iso

/iso/rhel-server-7.2-x86_64-dvd.iso

on /mnt/iso type iso9660 (ro,relatime)

Step9：本地YUM源生效后，就能直接使用yum install实现软件的快速安装部署；

[root@rhel7-01

~]# yum install vsftpd* -y
