在CentOS 7.3中創建本地yum源

1.掛載系統光盤

1.1創建掛載文件

[root@centos7?~]#?mkdir?/mnt/cdrom??????????????????????????#創建文件

1.2掛載光驅

[root@centos7?~]#?mount?/dev/cdrom?/mnt/cdrom/??????????????#掛載光驅?
mount:?/dev/sr0?is?write-protected,?mounting?read-only??????#掛載成功
[root@centos7?~]#?ll?/mnt/cdrom/????????????????????????????#查看掛載的文件夾total?1550

-r--r--r--.?1?root?root????2883?Dec??5?21:52?TRANS.TBL

2.修改yum文件

2.1 查看yum目錄

[root@centos7?~]#?ll?/etc/yum.repos.d/??????
total?28
-rw-r--r--.?1?root?root?1664?Nov?30?02:12?CentOS-Base.repo???????#網絡yum源文件
-rw-r--r--.?1?root?root?1309?Nov?30?02:12?CentOS-CR.repo
-rw-r--r--.?1?root?root??649?Nov?30?02:12?CentOS-Debuginfo.repo
-rw-r--r--.?1?root?root??314?Nov?30?02:12?CentOS-fasttrack.repo
-rw-r--r--.?1?root?root??656?May?18?10:05?CentOS-Media.repo??????#本地yum源文件
-rw-r--r--.?1?root?root?1331?Nov?30?02:12?CentOS-Sources.repo
-rw-r--r--.?1?root?root?2893?Nov?30?02:12?CentOS-Vault.repo

2.2 修改yum源文件

[root@centos7?~]#?nano?/etc/yum.repos.d/CentOS-Media.repo????#修改本地yum源文件?
#?CentOS-Media.repo
#
#??This?repo?can?be?used?with?mounted?DVD?media,?verify?the?mount?point?for
#??CentOS-7.??You?can?use?this?repo?and?yum?to?install?items?directly?off?the
#??DVD?ISO?that?we?release.
#
#?To?use?this?repo,?put?in?your?DVD?and?use?it?with?the?other?repos?too:
#??yum?--enablerepo=c7-media?[command]
#
#?or?for?ONLY?the?media?repo,?do?this:
#
#??yum?--disablerepo=\*?--enablerepo=c7-media?[command]

[c7-media]???????????????????????????????????????????#庫名稱
name=CentOS-$releasever?-?Media??????????????????????#名稱描述
baseurl=file:///media/CentOS/????????????????????????#yum源目錄，源地址
????????file:///media/cdrom/?????????????????????????#這三個是系統的默認本地yum源的地址
????????file:///media/cdrecorder/
gpgcheck=1???????????????????????????????????????????#檢查GPG-KEY，0為不檢查，1為檢查
#enabled=0???????????????????????????????????????????#是否用該yum源，0為禁用，1為使用
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7??#GPG-KEY秘鑰，gpgcheck的值為0時不需要配置

修改后

[c7-media]???????????????????????????????
baseurl=file:///mnt/cdrom/??????????????????????????#把掛載光盤文件的路徑加到這里???????????
????????file:///media/CentOS/?
????????file:///mdia/cdrom/????????????????
????????file:///media/cdrecorder/???????????
gpgcheck=1?????????????????????????????????
enabled=1???????????????????????????????????????????#把enabled的值改為1，啟用這個yum源

2.2 修改網絡yum源文件

[root@centos7?~]#?mv?/etc/yum.repos.d/CentOS-Base.repo{,.bak}???#把這個文件后面加上.bak繞過網絡yum源

3.驗證本地yum源

3.1清除本地緩存

[root@centos7?~]#?yum?clean?all

3.2查看本機yum源

[root@centos7?~]#?yum?repolist?
Loaded?plugins:?fastestmirror,?langpacks
c7-media?????????????????????????????????????????????????????????|?3.6?kB??00:00:00?????
(1/2):?c7-media/group_gz?????????????????????????????????????????|?155?kB??00:00:00?????
(2/2):?c7-media/primary_db???????????????????????????????????????|?5.6?MB??00:00:00?????
Determining?fastest?mirrors
*?c7-media:?
repo?id?????????????????????repo?name????????????????????????status
c7-media????????????????????CentOS-7?-?Media?????????????????9,363???????#創建的本地yum源
repolist:?9,363

3.3查看yum源里的安裝包

[root@centos7?~]#?yum?list?
telnet.x86_64????????????????????????1:0.17-60.el7???????????????????????c7-media??#這些文件的庫名都是本地yum源
telnet-server.x86_64?????????????????1:0.17-60.el7???????????????????????c7-media?
testng.noarch????????????????????????6.8.7-3.el7?????????????????????????c7-media?

本地yum源創建好了，現在就可以使用本地yum源來安裝軟件了
