On this host we need also to setup openSUSE Tools repository:

<source lang='bash'>
 
-
cd /etc/zypp/repos.d/;
 
-
wget http://download.opensuse.org/repositories/openSUSE:/Tools/openSUSE_11.2/openSUSE:Tools.repo

<source lang='bash'>
 
-
zypper in obs-server obs-signer obs-utils createrepo dpkg nfs-client
 
-
# obs-server brings these other packages as dependency. This is just for you to notice which packages are needed for Backend installation
 
-
# createrepo & dpkg are only recommends
 
-
# NFS client is needed as we use an NFS share for host/BE interchange

-
/usr/lib/obs/server/BSConfig.pm needs to point to correct server names corresponding to source server, where workers are going to download the source, and the repository server, where RPM repos are going to be shared to users.

For version 1.7 there are a new services. You can start them as well:
 
-
* '''obswarden'''
 
-
  It checks if build hosts are dying and cleans up hanging builds
 
-
* '''obssigner'''
 
-
  It is used to sign packages via the obs-sign daemon. You need to configure
 
-
  it in BSConfig.pm before you can use it.
 
-
* '''obsservice'''
 
-
  This is the source service daemon. OBS 1.7 just comes with a download
 
-
  service so far. This feature is considered to be experimental so far,
 
-
  but can be already extended with own services.
 
-
 
-
'''Install Lighttpd'''
 
-
 
-
lighttpd also needs to be available on backend server. This is required to provide directory listing on the repositories available on this server when an http/s request to maemo-repo is made through web ui.
 
-
 
-
<source lang='bash'>
 
-
zypper in lighttpd
 
-
</source>
 
-
 
-
Create a new file under /etc/lighttpd/vhosts.d/. It can be obs.conf as well, and add:
 
-
<source lang='bash'>
 
-
vi /etc/lighttpd/vhosts.d/obs.conf
 
-
 
-
$HTTP["host"] =~ "repo.obs.maemo.org" {
 
-
  server.name = "repo.obs.maemo.org"
 
-
 
-
  server.document-root = "/srv/obs/repos/"
 
-
  dir-listing.activate = "enable"
 
-
}
 
-
</source>
 
-
 
-
To enable vhosts, remember to '''uncomment''' the following in the 'custom includes':
 
-
 
-
<source lang='bash'>
 
-
vi /etc/lighttpd/lighttpd.conf
 
-
##

-
Also ensure the host has :
 
-
obs-worker (1.7.3)
 
-
qemu-svn
 
-
 
-
In order to run arm binaries in the Xen chroot we need to ensure the initrd inserts binfmt_misc

in /etc/sysconfig/kernel, set
 
-
  DOMU_INITRD_MODULES="xennet xenblk binfmt_misc

then
 
-
mkinitrd -k vmlinuz-2.6.31.12-0.2-xen -i initrd-2.6.31.12-0.2-xen-binfmt -B

On the backend machine edit /usr/lib/build/xen.conf to use the correct initrd

== Remove Power/PPC from monitor page==
 
-
 
-
We don't target PPC, so best remove it from the build monitor page:
 
-
 
-
On FE in webui/app/views/monitor/_plots.rhtml
 
-
 
-
Use html comments to disable the Power line:
 
-
 
-
<pre><!--<%= render :partial => 'graphs_arch', :locals => { :title => "Power", :prefix => 'ppc_' } %>--></pre>
 
-
 
-
On FE webui/config/environment.rb
