Put the package you want to add in:
/home/install/contrib/5.0/arch/RPMS |
Where arch is your architecture ("i386" or "x86_64").
Create a new XML configuration file that will extend the current compute.xml configuration file:
# cd /home/install/site-profiles/5.0/nodes # cp skeleton.xml extend-compute.xml |
Inside extend-compute.xml, add the package name by changing the section from:
<package> <!-- insert your package name here --> </package> |
to:
<package> your package </package> |
 | It is important that you enter the base name of the package in extend-compute.xml and not the full name. For example, if the package you are adding is named XFree86-100dpi-fonts-4.2.0-6.47.i386.rpm, input XFree86-100dpi-fonts as the package name in extend-compute.xml. |
<package>XFree86-100dpi-fonts</package> |
If you have multiple packages you'd like to add, you'll need a separate <package> tag for each. For example, to add both the 100 and 75 dpi fonts, the the following lines should be in extend-compute.xml:
<package>XFree86-100dpi-fonts</package> <package>XFree86-75dpi-fonts</package> |
Also, make sure that you remove any package lines which do not have a package in them. For example, the file should NOT contain any lines such as:
<package> <!-- insert your package name here --> </package> |
Now build a new Rocks distribution. This will bind the new package into a RedHat compatible distribution in the directory /home/install/rocks-dist/....
# cd /home/install # rocks-dist dist |
Now, reinstall your compute nodes.
Often on x86_64-based clusters, one wants to add the x86_64 and i386 version of a package to compute nodes. To do this, in your extend-compute.xml file, supply the section:
<package>pkg.x86_64</package> <package>pkg.i386</package> |
Where pkg is the basename of the package.
Now build a new Rocks distribution.
# cd /home/install # rocks-dist dist |
Now, reinstall your compute nodes.
