YUM是在Fedora和RedHat以及SUSE中基于rpm的軟件包管理器，它可以使系統管理人員交互和自動化地更細與管理RPM軟件包，能夠從指定的服務器自動下載RPM包并且安裝，可以自動處理依賴性關系，并且一次安裝所有依賴的軟體包，無須繁瑣地一次次下載、安裝。
RHEL7中的RedHat的YUM需要注冊付費才能使用，本文簡單介紹一下使用iso鏡像文件建立本地YUM源；
Step1：上傳RHEL7的鏡像文件到/iso目錄；
[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這個iso文件到/mnt/iso目錄；
[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：編輯repo文件，指定YUM路徑；
[rhel7_local]
name =
rhel7_local
baseurl =
file:///mnt/iso
enable = 1
gpgcheck = 0
Step5：建立YUM緩存數據庫，加快后續軟件安裝速度；
[root@rhel7-01
~]# yum makecache

(4/4):

Step6：編輯fstab，實現開機自動mount；
[root@rhel7-01
~]# cd /etc
[root@rhel7-01
etc]# vim fstab
Step7：添加最后一行內容，開機自動mount，需要指明iso9660文件類型；
/iso/rhel-server-7.2-x86_64-dvd.iso /mnt/iso iso9660 defaults 0 0
Step8：確認fstab有效性和正確性；
[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 實現軟件的快速安裝部署；
[root@rhel7-01
~]# yum install vsftpd* -y
