配置本地yum源的方法 

1. 挂载光驱

如果是上传iso镜像到服务器上，则直接挂载iso镜像即可：

#mount -o loop -t iso9660 /xxxx.iso /挂载目录

开机自动加载#vi /etc/rc.d/rc.local增加mount -o loop -t iso9660 /xxxx.iso /挂载目录

[root@namenode1]# mount /dev/cdrom /mnt

[root@namenode1 ]# ls /mntEFI      EULA_pt           README                    RELEASE-NOTES-it-IT.html  RELEASE-NOTES-ru-RU.html  RPM-GPG-KEY-redhat-releaseEULA     EULA_zh           RELEASE-NOTES-as-IN.html  RELEASE-NOTES-ja-JP.html  RELEASE-NOTES-si-LK.html  ScalableFileSystemEULA_de  GPL               RELEASE-NOTES-bn-IN.html  RELEASE-NOTES-kn-IN.html  RELEASE-NOTES-ta-IN.html  ServerEULA_en  HighAvailability  RELEASE-NOTES-de-DE.html  RELEASE-NOTES-ko-KR.html  RELEASE-NOTES-te-IN.html  TRANS.TBLEULA_es  images            RELEASE-NOTES-en-US.html  RELEASE-NOTES-ml-IN.html  RELEASE-NOTES-zh-CN.htmlEULA_fr  isolinux          RELEASE-NOTES-es-ES.html  RELEASE-NOTES-mr-IN.html  RELEASE-NOTES-zh-TW.htmlEULA_it  LoadBalancer      RELEASE-NOTES-fr-FR.html  RELEASE-NOTES-or-IN.html  repodataEULA_ja  media.repo        RELEASE-NOTES-gu-IN.html  RELEASE-NOTES-pa-IN.html  ResilientStorageEULA_ko  Packages          RELEASE-NOTES-hi-IN.html  RELEASE-NOTES-pt-BR.html  RPM-GPG-KEY-redhat-beta

2. 复制所有RPM包到指定目录：cp -rf /mnt/Packages /opt/local_yum/

3. 创建local.repo文件：

[root@namenode1 ]# vi /etc/yum.repos.d/local.repo  --把这个目录下原来的所有其它配置文件改名或删除

[rhel6]

name=rhel6

baseurl=file:///opt/local_yum/Packages

enabled=1

gpgcheck=0

4. 创建YUM库

# createrepo  -g  /yum/Server/repodata/comps-rhel5-server-core.xml  /opt/local_yum/Packages

5. 测试：yum list
