Add the Fedora13 installation disk as the disc Source

How to mount Fedora13iso to a local mounted iso image file: # mountFedora-13-i386-DVD.iso-tiso9660-oloop/mnt/cdrom/If Fedora13 enables the auto mount feature, it will automatically mount the disc to/media. Disk mounting method: # mount-tiso9660-oloop/dev/sr0/

Mount Fedora 13 iso to a local device

How to mount an iso image file:

# Mount Fedora-13-i386-DVD.iso-t iso9660-o loop/mnt/cdrom/

If ora 13 Enables automatic mounting, it will automatically mount the disc to/media.

How to mount a CD:

# Mount-t iso9660-o loop/dev/sr0/mnt/cdrom/

Back up the original repos configuration file

# Cd/etc/yum. repos. d/

# Mkdir backup

# Mv *. repo backup/

You can also use the tar command to back up data in one step.

Tar czf/home/repo.tar.gz/etc/yum. repos. d

Decompress the file with zxvf.

After the backup, set/etc/yum. repos. d/clear the directory or set enabled to 0 in each repo file to disable other sources. Otherwise, "Error: cannot retrieve repository metadata (repomd. xml) for repository: updates-released. please verify its path and try again. ."

Copy and install the Packages directory on the CD to/home. Because the CD cannot be written, you need the write permission to create the yum database file and information index file. Therefore, copy these rpm packages to a directory with write permission.

# Cp/mnt/cdrom/Packages/home

Create a new repos File

# Cdrom. repo:

[Cdrom]

Name = cdrom

Baseurl = file: // home/Packages

Enabled = 1

Gpgcheck = 0

; Gpgkey = file: /// mnt/cdrom/RPM-GPG-KEY-fedora-i386

Save and exit

ZZ

Install the rpm package of createrepo, which is included in the CD. A dependency package is required during installation, and is also available in the installation disk.

# Rpm-ivh createrepo *. rpm

Install yum database files and information index files (this step is important)

Createrepo-g/mnt/cdrom/repodata/repomd. xml/home/Packages

Refresh yum Cache

# Yum clean all

# Yum makecache

Extended: using the above ideas, you can copy the installation CD and common software packages to a server in the LAN, and then direct the yum source of other clients to this server, yum can be installed on the LAN. An example is provided below:

I. Experiment on two computers

1: Server RedHat Enterprise 5

Ip: 192.168.1.112

2: client RedHat Enterprise 5

Ip: 192.168.1.113

3: servers and clients can ping each other

Ii. Server Configuration:

1: Create the directory networkyum for storing the DVD Disc package under the/home/directory.

Run mkdir-p/home/networkyum

2: mount the DVD drive to/mnt/

Run the command: mount/dev/hdc/mnt/

3: Copy all files and subdirectories under v/mnt/Server/to/home/networkyum /.

Run the command cp/mnt/Server/*. */home/networkyum/

4: Install the rpm package createrepo

Run the command: rpm-ivh createrepo ...... ... . I386.rpm

5. Install the yum database file and information index file.

Run the following command: createrepo-g/home/networkyum/Server/repodata/compsrhel5-

Server-core.xml/home/networkyum/Serve

Iii. Client Configuration:

1: connect to the YUM repository of the server and create the file extension. repo in the/etc/yum. repos. d/directory.

File Name

Run the command: touch/etc/yum. repos. d/ftpyum. repo

2. Modify the ftpyum. repo file.

Run the command: vi/etc/yum. repos. d/ftpyum. repo

3: configuration file ftpyum. repo content:

[Server-ftp]

Name = Server-ftp

Baseurl = ftp: // 192.168.1.112/home/networkyum/Server

Enabled = 1

Gpgcheck = 0

4: Clear cache and refresh list

Run the command: yum clean all

Run the command: yum list

5: Test

Run the command: yum install dhcp

6: Completed Successfully
