Membuat DVD Repository Debian/Ubuntu

Disini akan di jelaskan bagaimana membuat DVD repository lokal, berikut adalah tahapanya

Membuat DVD repository lokal

Silakan buat dulu Repository lokal anda

Memecah Repository Menjadi ukuran DVD

Ukuran Repository yang terlalu besar menjadi kendala bagi kite semua, apalagi yang mempunyai bandwith pas-pasan. untuk pendistribusian repository, di indonesia telah di kembangkan DVD nya, hal ini membuat kesempatan bagi kita semua untuk menikmati repository. tetapi untuk memecah lagi repo di butuhkan suatu tool yaitu debpartial untuk itu install dulu deb partialnya

sudo apt-get install debpartial

pindah direktory yang terdapat reponya, dalam hal ini kita menggunakan direktory /var/www/ untuk root reponya.

cd /var/www

kemudian buat direktori untuk dvd

sudo mkdir ubuntu-dvd

atau untuk debian

su

mkdir debian-dvd

Setelah itu jalankan debpartial

debpartial --nosource --dirprefix=ubuntu --section=main,universe,multiverse,main/debian-installer --dist=gutsy --size=DVD ubuntu/ ubuntu-dvd/

atau untuk debian

debpartial --nosource --dirprefix=debian --section=main,contrib,non-free --dist=etch --size=DVD debian/ debian-dvd/

Buat berkas debcopy script debcopy menggunakan bahasa ruby untuk itu silakan install ruby terlebih dahulu

sudo apt-get install ruby

kemudian buat berkas debcopy, dan edit dengan editor kesukaan anda

sudo touch debcopy
sudo chmod +x debcopy
gksu gedit debcopy


isikan berkas debcopy dengan script berikut

#!/usr/bin/ruby#

# debcopy - Debian Packages/Sources partial copy tool

#

# Usage: debcopy [-l]

#

# where is a top directory of a debian archive,

# and is a top directory of a new debian partial archive.

#

# debcopy searches all Packages.gz and Sources.gz under /dists

# and copies all files listed in the Packages.gz and Sources.gz

# files into from . -l creates symbolic links

# instead of copying files.

end

["--help", "-h", GetoptLong::NO_ARGUMENT])

opts.each do |opt,arg|

case opt

when "--symlink"

$link = true

when "--help"

usage

end

end

usage if ARGV.size != 2

$source_dir = ARGV.shift

$dest_dir = ARGV.shift

if $link

$source_dir = Dir::pwd + "/" + $source_dir unless $source_dir =~ /\A\//

$dest_dir = Dir::pwd + "/" + $dest_dir unless $dest_dir =~ /\A\//

end

$stats = {}

$stats["ignore"] = 0

$stats["copy"] = 0

$stats["notfound"] = 0

open("|find #{$dest_dir}/dists -name Packages.gz") do |o|

o.each_line do |file|

file.chomp!

print "Processing #{file}... "

$stdout.flush

each_file(file) do |path|

copy(path)

end

puts "done"

end

end

open("|find #{$dest_dir}/dists -name Sources.gz") do |o|

o.each_line do |file|

file.chomp!

print "Processing #{file}... "

$stdout.flush

each_sourcefile(file.chomp) do |path|

copy(path)

end

puts "done"

end

end

puts "Number of Copied Files: " + $stats["copy"].to_s

puts "Number of Ignored Files: " + $stats["ignore"].to_s

puts "Number of Non-existence File: " + $stats["notfound"].to_s

diasumsikan tidak ada kendala, maka kemudian jalankan

ruby debcopy ubuntu/ ubuntu-dvd/ubuntu0ruby debcopy ubuntu/ ubuntu-dvd/ubuntu1

ruby debcopy ubuntu/ ubuntu-dvd/ubuntu2

ruby debcopy ubuntu/ ubuntu-dvd/ubuntu3

ruby debcopy ubuntu/ ubuntu-dvd/ubuntu4

Direktori ubuntu/ adalah direktori dimana hasil mirror yang telah anda lakukan dengan debmirror atau direktory dimana tempat repository ubuntu berada, sedangkan direktori ubuntu-dvd adalah direktori hasil pemecahan repository menjadi ukuran DVD. Bila anda menggunakan debian silakan subtitusi ubuntu dengan debian. Bila tidak ada masalah maka anda akan menjumpai direktori pool/ dan dists/ dalam direktori ubuntu-dvd/ubuntuX Buat berkas iso

sebelum di buat berkas iso alangkah baiknya bila di buat berkas md5sum nya dengan cara

cd ubuntu-dvd/ubuntu0 && find . -type f -print0 | xargs -0 md5sum > md5sum.txt

setelah itu buat berkas iso nya dengan memasukkan perintah

mkisofs -f -J -r -o ubuntu-dvd-0.iso ubuntu-dvd/ubuntu0

ulangi untuk dvd2 dan seterusnya…

mudah sekali bukan?

Catatan: anda juga dapat membuat ukuran repository dengan ukuran CD
