How Linux builds local yum warehouses by mounting the system CD

1. Mount the disc

Mount /dev/cdrom/media/cdrom/Mount:/dev/sr0 write-protected, mount as read-only

The CDROM directory under/dev is created in advance

2. Modify Yum configuration file (file location:/ETC/YUM.REPOS.D)

[Email protected]/]# cd/etc/Yum. repos.d/[[Email protected]Yum. repos.d]#mkdirbak #创建一个文件夹来存放多余的配置文件 [[email protected]Yum. repos.d]#MV* * bak/[[Email protected]Yum. repos.d]# CD bak/[email protected] bak]#lsCentOS-base.repo Centos-debuginfo.repo Centos-media.repo centos-Vault.repocentos-cr.repo Centos-fasttrack.repo centos-Sources.repo[[email protected] bak]#MVCentos-media.repo. /[email protected] bak]# CD ./[[Email protected]Yum. repos.d]#VICentos-media.repo

Save exit

3. Verification

We can view the warehouse with the Yum command plus the list parameter

[email protected]/]# Yum list  #后面东西太多了 ...
