首先在vm上安裝centos

1、首先查看掛載光盤的位置：#df -h

[root@lang ~]# df -h

Filesystem?????????????????? Size? Used Avail Use% Mounted on

/dev/mapper/vg_lang-lv_root?? 45G? 6.5G?? 37G? 16% /

tmpfs??????????????????????? 932M?? 76K? 932M?? 1% /dev/shm

/dev/sda1??????????????????? 485M?? 39M? 421M?? 9% /boot

/dev/sr0???????????????????? 4.2G? 4.2G???? 0 100% /media/CentOS_6.5_Final

2、創建文件夾 #mkdir /mnt/cdrom

3、將光盤掛載在/mnt/cdrom

# mount -t iso9660 -o ro /dev/sr0 /mnt/cdrom/

[root@lang ~]# ll /mnt/cdrom/

備注：卸載 umount /mnt/cdrom

4、進入到目錄：/etc/yum.repos.d/

[root@lang yum.repos.d]# ll

total 16

-rw-r--r--. 1 root root 1926 Nov 27? 2013 CentOS-Base.repo

-rw-r--r--. 1 root root? 638 Nov 27? 2013 CentOS-Debuginfo.repo

-rw-r--r--. 1 root root? 563 Dec? 6 04:55 CentOS-Media.repo

-rw-r--r--. 1 root root 3664 Nov 27? 2013 CentOS-Vault.repo

更改后綴名：

[root@lang yum.repos.d]# rename .repo .repo.bak *

[root@lang yum.repos.d]# ll

total 16

-rw-r--r--. 1 root root 1926 Nov 27? 2013 CentOS-Base.repo.bak

-rw-r--r--. 1 root root? 638 Nov 27? 2013 CentOS-Debuginfo.repo.bak

-rw-r--r--. 1 root root? 563 Dec? 6 04:55 CentOS-Media.repo.bak

-rw-r--r--. 1 root root 3664 Nov 27? 2013 CentOS-Vault.repo.bak

[root@lang yum.repos.d]# mv CentOS-Media.repo.bak CentOS-Media.repo

[root@lang yum.repos.d]# ll

total 16

-rw-r--r--. 1 root root 1926 Nov 27? 2013 CentOS-Base.repo.bak

-rw-r--r--. 1 root root? 638 Nov 27? 2013 CentOS-Debuginfo.repo.bak

-rw-r--r--. 1 root root? 563 Dec? 6 04:55 CentOS-Media.repo

-rw-r--r--. 1 root root 3664 Nov 27? 2013 CentOS-Vault.repo.bak

編輯CentOS-Media.repo 改一下兩個紅色標記的地方

[c6-media]

name=CentOS-$releasever - Media

baseurl=file:///mnt/cdrom

gpgcheck=1

enabled=1

gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-6

5、yum基礎操作

[root@lang ~]# yum clean all

Loaded plugins: fastestmirror, refresh-packagekit, security

Cleaning repos: c6-media

Cleaning up Everything

Cleaning up list of fastest mirrors

[root@lang ~]# yum repolist

Loaded plugins: fastestmirror, refresh-packagekit, security

Determining fastest mirrors

c6-media????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????? | 4.0 kB???? 00:00 ...

c6-media/primary_db?????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????? | 4.4 MB???? 00:00 ...

repo id????????????????????????????????????????????????????????????????????????????????????????? repo name???????????????????????????????????????????????????????????????????????????????????????????????? status

c6-media???????????????????????????????????????????????????????????????????????????????????????? CentOS-6 - Media????????????????????????????????????????????????????????????????????????????????????????? 6,367

repolist: 6,367

6、可以使用yum安裝gcc、httpd等基礎軟件。
