CentOS to build Yum server by means of CD-ROM mount

Introduction of experimental environment

Create a new two virtual machine using VMware Workstation, install CentOS release 6.4 (Final) x86_64

The iptables and SELinux of both hosts have been closed.

CentOS1 plan to install Yum Data Warehouse IP as 192.168.80.3

CentOS2 plan acts as a client IP for 192.168.80.4

Build local yum server via CD-ROM

This experiment program through VSFTP to act as Yum Data Warehouse, need to pre-installed the following software:

VSFTP, FTP, Createrepo

The above software we first by mounting the CD-ROM, build the local source, to install

1. Mount CD

# mount/dev/cdrom/media/

Mount:block Device/dev/sr0 is write-protected, mounting read-only

2. Check whether the mount is successful

# df-h

FileSystem Size Used Avail use% mounted on

/dev/mapper/volgroup-lv_root

18G 2.0G 15G 13%/

Tmpfs 495M 0 495M 0%/dev/shm

/DEV/SDA1 485M 33M 427M 8%/boot

/dev/sr0 4.1G 4.1G 0 100%/media

/media's already mounted.

3. Confirm the Repomd.xml Path

# find/media/-name Repomd.xml

/media/repodata/repomd.xml

Yum need to read the software dependencies file Repomd.xml

But different discs, the location of this file may not be the same, such as my hand, another Rhel CD image

# Mount-o Loop rhel-server-5.4-i386-dvd.iso/mnt

# find/mnt/-name Repomd.xml

/mnt/cluster/repodata/repomd.xml

/mnt/clusterstorage/repodata/repomd.xml

/mnt/server/repodata/repomd.xml

/mnt/vt/repodata/repomd.xml

As you can see, there is no/repodata directory below the/mnt directory, and if we configure the Yum client below, there will be an error when specifying the path to the data warehouse directly as/MNT, in case we first confirm the location of the file.

4. Back up repo files

# cd/etc/yum.repos.d/

# ls

Centos-base.repo Centos-debuginfo.repo Centos-media.repo Centos-vault.repo

# rename Repo Repo.bak *

# ls

Centos-base.repo.bak Centos-debuginfo.repo.bak Centos-media.repo.bak Centos-vault.repo.bak

5. New Yum Client configuration file Centos-local.repo

We can use the Centos-debuginfo.repo.bak file to make a template

# cp-a Centos-debuginfo.repo.bak Centos-local.repo

# Vi/etc/yum.repos.d/centos-local.repo
