1.挂在光盘,配置软件源(光盘挂载在/yum)
[root@localhost ~]# mkdir /yum
[root@localhost ~]# mount /dev/cdrom /yum
mount: block device /dev/sr0 is write-protected, mounting read-only
[root@localhost ~]# cd /etc/yum.repos.d/
[root@localhost yum.repos.d]# ls
CentOS-Base.repo CentOS-Debuginfo.repo CentOS-fasttrack.repo CentOS-Media.repo CentOS-Vault.repo
[root@localhost yum.repos.d]# mkdir bak
[root@localhost yum.repos.d]# mv CentOS-* bak/
[root@localhost yum.repos.d]# vim lulin.repo
[root@localhost yum.repos.d]# cat lulin.repo
[lulin]
name=lulin
baseurl=file:///yum
gpgcheck=0
enabled=1
[root@localhost yum.repos.d]#
[root@localhost ~]# yum clean all
[root@localhost ~]# yum repolist
Loaded plugins: fastestmirror, refresh-packagekit, security
Loading mirror speeds from cached hostfile
lulin | 4.0 kB 00:00 ...
lulin/primary_db | 4.5 MB 00:00 ...
repo id repo name status
lulin lulin 6,518
repolist: 6,518
2.安装必要的软件
[root@localhost ~]# yum -y install anaconda repodata createrepo mkisofs rsync
3.拷贝镜像内的文件,除了repodate文件夹
[root@localhost ~]# mkdir /myCentos
[root@localhost ~]#/usr/bin/rsync -a --exclude=repodata/ /yum/ /myCentos/
4.创建repodata目录
[root@localhost myCentos]# mkdir repodata
5.将“*-x86_64-comps.xml”文件拷贝到/myCentos/repodata路径下，并重命名成comps.xml。由于centos6.5下的comps.xml文件名很长，这里“*”为省略符，实际操作时输入完整文件名。
[root@localhost myCentos]#cp /yum/repodata/*-x86_64-comps.xml /myCentos/repodata/comps.xml
此文件保存的软件分组信息,需要保留并用它生成repodata信息
6.将新添加的软件拷贝到Packages目录
[root@localhost myCentos]# cp /root/ntfs-3g-2017.3.23-1.el6.x86_64.rpm /myCentos/Packages/
7.切换到/myCentos目录
8.获取光盘信息变量
[root@localhost myCentos]# declare -x discinfo=`head -1 .discinfo`
生成新的repodata
[root@localhost myCentos]# createrepo -u "media://$discinfo" -g repodata/comps.xml .

9.cd到家目录,在家目录制作光盘
[root@localhost ~]# mkisofs -o myCentOS.iso -b isolinux/isolinux.bin -c isolinux/boot.cat -no-emul-boot -boot-load-size 4 -boot-info-table -R -J -v -T /myCentos/
10.测试
[root@localhost ~]# mkdir /myyum
[root@localhost ~]# mount myCentOS.iso /myyum/ -o loop
[root@localhost ~]# vim /etc/yum.repos.d/lulin.repo
[root@localhost ~]# cat /etc/yum.repos.d/lulin.repo
[lulin]
name=lulin
#baseurl=file:///yum
baseurl=file:///myyum
gpgcheck=0
enabled=1
原光盘
[root@localhost ~]# yum repolist
Loaded plugins: fastestmirror, refresh-packagekit, security
Determining fastest mirrors
lulin | 4.0 kB 00:00 ...
lulin/primary_db | 4.5 MB 00:00 ...
repo id repo name status
lulin lulin 6,518
repolist: 6,518
新光盘
[root@localhost ~]# yum repolist
Loaded plugins: fastestmirror, refresh-packagekit, security
Determining fastest mirrors
lulin | 3.9 kB 00:00 ...
lulin/primary_db | 3.5 MB 00:00 ...
repo id repo name status
lulin lulin 4,185
repolist: 4,185
Repolist少了2000+个.但事实上,软件包个数没有减少
11.测试安装ntfs-3g
[root@localhost ~]# yum install ntfs-3g
Loaded plugins: fastestmirror, refresh-packagekit, security

成功
12.测试安装
成功
测试建立本地源.,安装ntfs-3g
因为ntfs-3g是自己导入的,没有认证
所以先测试开启gpgcheck=1是否可以安装
经测试,安装失败
将gpgcheck=0
测试
安装成功.
也就是说,自己增加的软件,因为没有认证.也没有导入key,所以需关闭gpgcheck来安装
