New page

=== Install files for a new OS ===
==== SL5 OS ====
*Connect to quattorrepository.begrid.be
*Each directory under /data/html/begrid/install corresponds to an OS+architecture :
<pre>
ls -al /data/html/begrid/install/
...
drwxr-xr-x. 3 apache apache 4096 Nov 18 2010 sl440-x86_64
drwxr-xr-x. 4 apache apache 4096 Nov 17 2010 sl450-i386
drwxr-xr-x. 4 apache apache 4096 Nov 18 2010 sl500-i386
drwxr-xr-x. 5 apache apache 4096 Nov 18 2010 sl500-x86_64
...
</pre>
*Let's we want the install files for SL53 64 bits :
<pre>
cd /data/html/begrid/install/
mkdir sl530-x86_64
nohup rsync -avSH --delete --exclude=build --exclude=contrib --exclude=isolinux --exclude=RHupdates --exclude=RPM-GPG-KEYs --exclude=sites --exclude=SL.documentation --exclude=updates rsync://rsync.scientificlinux.org/scientific/53/x86_64/ /data/html/begrid/install/sl530-x86_64/
</pre>
*The directory must be owned by apache :
<pre>
chown -R apache:apache /data/html/begrid/install/sl530-x86_64
</pre>

==== SL6 OS ====
The procedure is the same as the one for SL5 OS, except for the rsync. Let's say we want the install files for SL63 64 bits :
<pre>
cd /data/html/begrid/install/
mkdir sl630-x86_64
nohup rsync -avkSH --delete rsync://rsync.scientificlinux.org/scientific/6.3/x86_64/os/ /data/html/begrid/install/sl630-x86_64/
</pre>

=== PXE files for a new OS ===
*Log in on the Quattor client.
*Let's say you want to add support for SL53 64 bits :
<pre>
mkdir /osinstall/nbp/sl530_x86_64
cd /osinstall/nbp/sl530_x86_64
wget ftp://distrib-coffee.ipsl.jussieu.fr/pub/linux/scientific-linux/53/x86_64/images/pxeboot/initrd.img
wget ftp://distrib-coffee.ipsl.jussieu.fr/pub/linux/scientific-linux/53/x86_64/images/pxeboot/vmlinuz
</pre>

=== Generation of OS PAN templates ===
As an example, we will show how to generate OS templates for SL64 :
*Log in as root on the Quattor repository.
*In /root/quattor_os_templates, you will find the directories external and misc, containing the tools to generate the templates. These directories were obtained by doing :
<pre>
cd /root/quattor_os_templates
svn co https://svn.lal.in2p3.fr/LCG/QWG/SCDB/trunk/utils/misc
svn co https://svn.lal.in2p3.fr/LCG/QWG/SCDB/trunk/external
</pre>
In the same location, you must also create the directory where to put the PAN templates :
<pre>
mkdir -p /root/quattor_os_templates/sl64_templates/rpms
</pre>
Very important : the path of this last directory must end with "rpms".
*Copy the file comps.dtd to the repodata directory of the OS installation files :
<pre>
cp /usr/share/doc/comps-extras-17.8/comps.dtd /data/html/begrid/install/sl640-x86_64/repodata/
</pre>
*Go to the misc directory and make sure that the the scripts that will be used have the "x" permission :
<pre>
chmod u+x buildOSTemplates
chmod u+x *.pl
</pre>
*Run the following command :
<pre>
./buildOSTemplates --compsdir repodata --compsxml comps-sl6-x86_64.xml --debug --rpmdir Packages --scdbroot /root/quattor_os_templates /data/html/begrid/install/sl640-x86_64 /root/quattor_os_templates/sl64_templates/rpms
</pre>
