4-2 Disc Yum Source setup

Yum source defaults to using the network as the Yum source, in some special cases, such as teaching, laboratory, etc., not all environments can be networked

You can use a disc to build a Yum source without using the network

We know that the disc contains all the RPM packages, so it is possible to use the CD to build a local Yum source

1. Mount the disc

<1> set up a mount point

Mkdir/mnt/cdrom

<2> Mount Disc (note virtual machines open the optical drive and select the desired image)

mount/dev/sr0/mnt/cdrom/

Or Mount/dev/cdrom/mnt/cdrom//cdrom seems to be sr0 link

2. Invalidating the network Yum source

<1> go to the Yum source directory

cd/etc/yum.repos.d/

<2> Modify the Yum source file suffix to invalidate it

MV Centos-base.repo Centos-base.repo.bak

Description

In fact, you can add enabled=0 to the Centos-base.repo file to make it effective,

But the Centos-base.repo default has 3, the modification is more cumbersome,

Therefore, by changing it to a name and adding a suffix to invalidate it

Because you may later want to install the online, it is not recommended to delete

3. Bring the disc yum source (Centos-media.repo) into effect

<1>vim Centos-media.repo #具体参数含义可以参考前面的介绍

--------------------------------------------------------------------------------------------------------------- --------------

[C6-media]

name=centos-$releasever-media

Baseurl=file:///mnt/cdrom #地址为你自己的光盘挂载地址

# File:///media/cdrom

# file:///media/cdrecorder/#注释这两个不存在的地址

Gpgcheck=1

Enabled=1 #把enabled = 0 to enabled=1, let this yum source configuration file take effect

Gpgkey=file:///ect/pki/rpm-gpg/rpm-gpg-key-centos-6 #默认就是这个, do not modify can

--------------------------------------------------------------------------------------------------------------- --------------

<2> can use the command Yum list to see which packages are installed in the Yum source to check if the Yum source is set up.

Yum List #列出的结果 its Yum source as container name

After successfully building the <3> disc yum source, you can use Yum to install the
