Enable Trusty KickStart For SpaceWalk

TurnToJPG -->

Import distro-tree

Copy iso content into the distro-tree:

# mount -t  iso9660 -o loop /mnt/iso/ubuntu-14.04.3-server-amd64.iso /mnt1/
# mkdir /var/distro-trees/ubuntu-14.04.3-amd64
# chmod 755 /var/distro-trees/ubuntu-14.04.3-amd64/
# cp -ar /mnt1/* /var/distro-trees/ubuntu-14.04.3-amd64/

We will copy the pxeboot startup file from CentOS7 into ubuntu14.04 distro tree for cheating the spacewalk:

# mount -t iso9660 -o loop /mnt/iso/CentOS-7-x86_64-Everything-1503-01.iso /mnt2/
# mkdir -p /var/distro-trees/ubuntu-14.04.3-amd64/images/pxeboot/
# cp /mnt2/images/pxeboot/{initrd.img,vmlinuz} /var/distro-trees/ubuntu-14.04.3-amd64/images/pxeboot/
# ls /var/distro-trees/ubuntu-14.04.3-amd64/images/pxeboot/ -l -h


Now in spacewalk go to Systems->Kickstart->Distributions, with the parameters like following picture:

We copy the CentOS Kernel and initrd, so Spacewalk use redhat parameters for this distribution, later we will fix this.

Now create a profile via go to Systems->Kickstart->Profiles and “upload a new kickstart file”, just like following picture.


We fix the hardcoded breed from redhat to ubuntu via following steps:

Get the list info via cobbler list:


Report the selected distro info:

# cobbler distro report --name=trustyamd64:1:SpacewalkDefaultOrganization


Edit it like following:

# cobbler distro edit --name trustyamd64:1:SpacewalkDefaultOrganization --breed=ubuntu --os-version=jaunty --initrd=/var/distro-trees/ubuntu-14.04.3-amd64/install/netboot/ubuntu-installer/amd64/initrd.gz --kernel=/var/distro-trees/ubuntu-14.04.3-amd64/install/vmlinuz 

We should notice the initrd file and kernel has been modified!!!


Now edit the /var/lib/tftpboot/pxelinux.cfg/default file, find the item and modify it like following:

LABEL trustykickstart:1:SpacewalkDefaultOrganization
        kernel /images/trustyamd64:1:SpacewalkDefaultOrganization/vmlinuz
        MENU LABEL trustykickstart:1:SpacewalkDefaultOrganization
        append initrd=/images/trustyamd64:1:SpacewalkDefaultOrganization/initrd.gz  ks= ksdevice=eth0 --
        ipappend 2

Now you could kickstart your ubuntu trusty now.

Register to SpaceWalk

First create a key under spacewalk for activating all of the trusty clients:

Register the client via:

# apt-get install apt-transport-spacewalk rhnsd
# vim /usr/lib/python2.7/xmlrpclib.py
    def dump_nil (self, value, write):
    - if not self.allow_none:
    - raise TypeError, "cannot marshal None unless allow_none is enabled"
    +# if not self.allow_none:
    +# raise TypeError, "cannot marshal None unless allow_none is enabled"
# apt-get install python-libxml2
# mkdir /var/lock/subsys
# vim /etc/hosts      spacewalk
# rhnreg_ks --activationkey=1-trustyamd64 --serverUrl=http://spacewalk/XMLRPC
Warning: unable to enable rhnsd with chkconfig

Register to the main channel:

# cat /etc/apt/sources.list.d/spacewalk.list
deb spacewalk://spacewalk channels: main
# apt-get update

Added more software channels in the spacewalk web.


Update it via:

# apt-get update && apt-get update

Met many problems, perhaps the repository error.

Fix Bug, In spacewalk server, change following items:

[root@spacewalk trusty-ia32]# cat Packages | grep -i "Package: python$" -A2
Package: python
Version: 2.7.5-5ubuntu3
Multi-Arch: allowed
[root@spacewalk trusty-ia32]# cat Packages | grep -i "Package: python3$" -A2
Package: python3
Version: 3.4.0-0ubuntu2
Multi-Arch: allowed
[root@spacewalk trusty-ia32]# pwd

And regenerate the Packages.gz via:

# rm -f Packages.gz
# gzip -c Packages Packages.gz

Now re-install firefox you won’t meet problem.

Enable “Push”

Install the packages, precise’s package will also be OK for trusty.

Notice, the Trusty could use saucy based deb.

$ wget https://launchpad.net/~mj-casalogic/+archive/ubuntu/spacewalk-ubuntu/+files/rhncfg_5.10.14-1ubuntu1%7Esaucy2_all.deb
$ wget https://launchpad.net/~mj-casalogic/+archive/ubuntu/spacewalk-ubuntu/+files/osad_5.11.27-1ubuntu1%7Esaucy5_all.deb
$ wget https://launchpad.net/~mj-casalogic/+archive/ubuntu/spacewalk-ubuntu/+files/pyjabber_0.5.0-1.4ubuntu3%7Esaucy1_all.deb
$ sudo dpkg -i osad_5.11.27-1ubuntu1~saucy5_all.deb
$ sudo dpkg -i pyjabber_0.5.0-1.4ubuntu3~saucy1_all.deb

Import the certification file and modify the osad’s certification file:

# cd /usr/share/rhn
# wget http://spacewalk.example.com/pub/RHN-ORG-TRUSTED-SSL-CERT
# vim /etc/sysconfig/rhn/up2date
# vim /etc/sysconfig/rhn/osad.conf
osa_ssl_cert = /usr/share/rhn/RHN-ORG-TRUSTED-SSL-CERT
# service osad start
# update-rc.d osad defaults
# reboot

If you encounter problem, check the version of the osad/pyjabber, remove the precise version and install saucy version on Trusty via dpkg -P osad && dpkg -P pyjabber, install the right version, then everything will becomes OK.

Enable Remote Command

Install and Configure it via:

# dpkg -i rhncfg_5.10.14-1ubuntu1~saucy2_all.deb 
# rhn-actions-control --enable-run
# mkdir /var/spool/rhn

Also add configuration:

Now you could run command in spacewalk backend.


Following the tips on http://cefs.steve-meier.de/
Import erratas into the system.

# ./errata-import.pl --server spacewalk --errata ./errata.latest.xml  --rhsa-oval \
./com.redhat.rhsa-all.xml --channel centos6-i386 --os-version 6 --publish
