| How To Set Up A Local Yum Repository On Fedora 8

Creating a local repository.

🔗 Operating Environment

yum install yum-utils

This package will enable you to download packages, without installing them. So you can populate your kickstart server with packages that didn't come with the Install media.

🔗 Administration

🔗 Creating the NFS export Structure

1. mkdir -p /exports/ks/configs
2. mkdir -p /exports/ks/images
3. update /etc/exports

/exports/ks/config             192.168.42.0/255.255.255.0(ro,no_root_squash)

1. service nfs restart

🔗 populate an install directory for kickstart use

1. mount -o loop /exports/isos/images/rhel6beta2.iso /mnt
2. pushd /mnt
3. cp -r * /exports/ks/images/rhel6beta2
4. update /etc/exports

/exports/ks/images/rhel6beta2  192.168.42.0/255.255.255.0(ro,no_root_squash)

🔗 Kickstart config file

To create the config file use:

Fedora

/usr/bin/system-config-kickstart

# Kickstart file automatically generated by anaconda.

# Tells the system to install a fresh system rather than upgrade an existing system.
install

# Install from the NFS server specified.
nfs --server=192.168.42.132 --dir=/exports/ks/images/rhel6beta2

# If present, X is not configured on the installed system.
skipx

# Perform the kickstart installation in text mode.
text

# Installation logging level
logging --level=info


# Sets up the authentication options for the system.
authconfig --enableshadow --enablemd5

# Sets the system's root password
rootpw --iscrypted XXXXXXXXXXXXXXXXXXXXXXXXXXX


lang en_US.UTF-8
keyboard dk
timezone --utc Europe/Copenhagen

# Configures network information for the system.
network  --device=eth0 --bootproto=dhcp --onboot=on
network  --device=eth2 --bootproto=dhcp --onboot=on
network  --device=eth3 --bootproto=dhcp --onboot=on


firewall --disabled
selinux --disabled

bootloader --location=mbr
# Clear the Master Boot Record
zerombr

clearpart --all --initlabel
part / --fstype="ext3" --size=14000

🔗 Adding a package to the repository

• yumdownloader sysstat: Downloads the 'sysstat' packages, to the current directory, and with the same architecture as the current system architechture.
  • 'uname -m' will print the system architecture.

🔗 Local repository

See the reference in the reference list.

1. yum install lighttpd
2. vi /etc/lighttpd/lighttpd.conf
   • enable mod_aliases
   • add 'alias.url = ( "/yum" => "/exports/isos/repos" )'
3. chkconfig lighttpd on
4. /etc/init.d/lighttpd start
