{{WorkInProgressNeedsUpdate}} This article contains specifications, construction steps, and implementation information for a "build machine" for the "Amahi Express Installation Disc". The intent of the machine is to aid in the development and building of new Amahi Express Installation disc images.__TOC__<br>
'''Please Note:'''
*Since this article is a "work in progress", information in this article will be fluid for sometime, your patience will be appreciated. The author has never been down this path before.
* Any advice or suggestions you may have please post to the '''[https://forums.amahi.org/viewforum.php?f=44 Amahi Wiki "Express Disc" Forum]'''.
* The "Category" link, "Amahi Express Collection", at the bottom of this page provides links to other reference information relating to the "Amahi Express" subject area.
=== Recommended Configuration ===
* Latest full version of the Fedora ( this article will reference Fedora 18 32-bit) DVD.
* As modern of a computer as possible ( machine for this article used: Intel Core 2 Duo @ 3.0 GHz, 4GB RAM, 160 GB Hard Disk ).
* External storage facility ( i.e. external USB drive (1 TB?), Amahi share, Amahi ownCloud directory) with storage greater that the size of the build machine.
'''/(root partition):''' LVM partition, ext4 format, size set to the remaining space for the hard drive(s).
* Ensure that Fedora updates are done after the DVD installation.
* Create "mount points" for use later.
<blockquote><pre>|mkdir -p /media/optdrive
mkdir -p /media/usbdrive
mkdir -p /media/usbstick</pre></blockquote>
* Install the following packages.
<blockquote><pre>yum -y install system-config-kickstarts # graphical interface for making kickstart files
yum -y install pungi # tool to create anaconda based installation trees/isos
yum -y install createrepo # tool to refesh repo databases</pre></blockquote>
* Optionally install the following packages.
<blockquote><pre>yum -y install fedora-kickstarts # kickstarts used to compose the official Fedora Spins
# sample kickstarts stored at /usr/share/spin-kickstarts
yum -y install custom-kickstarts # kickstart files for Custom Spins
# sample kickstarts stored at /usr/share/spin-kickstarts/custom</pre></blockquote>
=== Local Fedora Repositories ===
To reduce the amount of software packages that might have to be downloaded during a disc build process, local Fedora "base" and "updates" repositories should be used. These local repositories (repos) have an added advantage as , the build machine can receive its' software updates ( i.e. yum -y update ) from them.
The repos in this example will be stored in the "/opt" directory. What is this directory normally used for? I am so glad you asked.
==== Construct the Repositories ====
* Start a "terminal session" and switch to the "root" user.
* Create local repository directory structures.
<blockquote><pre>mkdir -p /opt/fedora/f18/i386/base
mkdir -p /opt/fedora/f18/i386/updates</pre></blockquote>
* Mount the Fedora DVD.
<blockquote><pre>mount -o loop /dev/sr0 /media/optdrive</pre></blockquote>
* Copy rpm packages to the local "base" repo directory structure.
<blockquote>{<pre>cp -av /media/optdrive/Packages/* /opt/fedora/f18/i386/base</pre></blockquote>
* Copy the main "comps xml" file to the local "base" repo directory structure.
<blockquote><pre>cp /media/optdrive/repodata/*comps*.xml /opt/fedora/f18/i386/base/comps.xml</pre></blockquote>
* The production Anaconda Installer for Fedora 18 has a bug that will not allow discs to be built. A "test" version is available that allows discs to be built.
* Go to the Fedora 18 URL "<nowiki>http://mirrors.kernel.org/fedora/updates/testing/18/i386/</nowiki>" and download the following Packages:
<blockquote><pre>anaconda-18.37.12-1.fc18.i686.rpm
anaconda-dracut-18.37.12-1.fc18.noarch.rpm
anaconda-widgets-18.37.12-1.fc18.i686.rpm</pre></blockquote>
* Go to the "base", Packages, "a" directory and remove the following production Anaconda Installer packages:
<blockquote><pre>anaconda-18.37.11-1.fc18.i686.rpm
anaconda-dracut-18.37.11-1.fc18.noarch.rpm
anaconda-widgets-18.37.11-1.fc18.i686.rpm</pre></blockquote>
* Copy the downloaded "testing" Anaconda "version 12" packages to the "base", Packages, "a" directory.
* Go to the local "base" repo and generate the "base" repo files.
<blockquote><pre>cd /opt/fedora/f18/i386/base # go to the base package directory
createrepo . # refresh the "base" repo database
createrepo -g comps.xml . # refresh the comps.xml for group changes</pre></blockquote>
:Please notice the "dot" after createrepo, it's important.
* Populate the "updates" repo.
/bin/rsync -auvrt --delete --exclude=debug/ --exclude=drpms/ rsync://mirrors.kernel.org/fedora/updates/18/i386/
/opt/fedora/f18/i386/updates
:Please note this will take several hours to complete. Do it at night and check the next day.
* Go to "updates" repo and generate the "updates" repo files.
<blockquote><pre>cd /opt/fedora/f18/i386/updates
createrepo .</pre></blockquote>
==== Create the "yum" Repository Files ====
* Start a terminal sessions and switch to the root user.
* Go to the /etc yum configuration directory.
<blockquote><pre>cd /etc/yum.repos.d</pre></blockquote>
* Using a text editor create the "f18-base-local.repo" file and insert the following text, and then save the file.
<blockquote>
<pre>[f18-base-local]
name=Fedora 18 local base repository
baseurl=file:///opt/fedora/f18/i386/base
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-fedora-18-primary
enabled=1</pre></blockquote>
* Using a text editor create the "f18-updates-local.repo" file and insert the following text, and then save the file.
<blockquote>
<pre>[f18-updates-local]
name=Fedora 18 local updates repository
baseurl=file:///opt/fedora/f18/i386/updates
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-fedora-18-primary
enabled=0</pre></blockquote>
'''PLEASE NOTE:''' The updates repository is disabled due to a Fedora 18 bugs (2 known bugs on Red Hat Bug Tracker) in the Anaconda Installer.
* Disable all of the existing default repositories by editing each ".repo" file and setting "enabled=0" (from 1).
==== Test the Repositories ====
* Start a terminal sessions and switch to the root user.
* Enter the following commands.
<blockquote><pre>yum clean all
yum repolist</pre></blockquote>
* Something like this with other stuff will be displayed.
<blockquote>
<pre>repo id
f18-base-local
f18-updates-local</pre></blockquote>
==== Refreshing a Repository ====
* Now the updates repo will need to be updated on a regular basis. This can be done manually or a script file that is run on a nightly basis with the following commands.
# rsync to download new rpms
/bin/rsync -auv --delete --exclude=debug/ --exclude=drpms/ rsync://mirrors.kernel.org/fedora/updates/18/i386/
/opt/fedora/f18/i386/updates
# go to the updates directory and rebuild the repo database
cd /opt/fedora/f18/i386/updates
createrepo .
==== Fringe Benefit ====
* The "build" machine's Fedora 18 can be updated from the local repo by "yum -y --enablerepo=f18-updates-local update". Cool yes?
