 Posted: Sun May 28, 2006 12:47 pm Post subject: Kernel Building & buildpkg |
 |
|
I have 8 identical servers. One of my servers is setup as my local portage repository. This server's make.conf is configured with buildpkg. So I basically use this one server to build out binary packages that the other 7 server 'feed' on.
I would like to do the same thing for Kernels, but I do not see an obvious way to do this. I thought genkern could produce kernel packages that I could use, but I do not see an option for that. Will I just have to write an ebuild, that pulls the sources, applies patches, and compiles kernel based on supplied .config ?
Any ideas, pointers, or help is much appreciated. |

Well, I have a similar situation with 4 servers and I don't bother with package compiling.
I have one /usr/portage and /usr/src on one server, and they are shared over nfs. All of the servers mount these directories to theire /usr/portage and /usr/src. I have distcc installed on them, when I update portage or kernel, it uses all of the processors in my network for compiling.
The base machines /boot directory is also shared, but not automatically mounted on the other servers.
I have this script on the BASE MACHINE:
| Code: | # cat /etc/cron.daily/gentoo-sync
#!/bin/sh
/usr/bin/emerge --sync > /var/log/gentoo-sync.log # Syncronising portage
/usr/bin/emerge -ufDN world >> /var/log/gentoo-sync.log # Downloads sources without compiling
eclean-dist -f -t 12w # Checks and clears old sources from /usr/portage/distfiles
|
And this one on the TARGET MACHINES
| Code: | # cat /etc/cron.daily/gentoo-sync
#!/bin/sh
/usr/bin/emerge -ufDN world >> /var/log/gentoo-sync.log
|
For compiling I use distcc by this config file:
| Code: | # cat /etc/conf.d/distccd
DISTCCD_OPTS="--jobs 3 --daemon"
DISTCCD_EXEC="/usr/bin/distccd"
DISTCCD_PIDFILE="/var/run/distccd/distccd.pid"
DISTCCD_OPTS="${DISTCCD_OPTS} --port 3632"
DISTCCD_OPTS="${DISTCCD_OPTS} --log-level critical"
DISTCCD_OPTS="${DISTCCD_OPTS} --allow <IP ADDRESS> --allow <IP Address2> and so on ...."
DISTCCD_NICE="19"

In summary:
1. Then, I start this, to compile a kernel on the BASE MACHINE:
| Code: | | # genkernel --kernel-config=<hostname>-kernel-config --kernname=<hostname> --kernel-cc=distcc --kernel-cc=distcc |
2. I log in the TARGET MACHINE, then I copy the kernel to its /boot directory, for example:
| Code: |
cp /baseboot/kernel-hostname /boot
cp /baseboot/initrd-hostname /boot
|
3. Edit grub.conf on the TARGET MACHINE, if it is neccessary, but you can only copy the kernel and initrd with the same name everytime to avoid this.
4. Whenever I want to update a portage just log in the TARGET MACHINE over ssh and start "nice -n 19 emerge -uDN world", without waiting for syncronising or downloading.
5. Then angle of the dangle  |

Well I thank you for your indepth post. That isn't the method I was hoping for. I would much prefer having a binary package of the kernel to be able to distribute.
Seems my only alternative it to work at learning the ebuild system more, and getting my kernel built into a package that way. It is just a shame, since it seems that genkern has almost all the functionality, except building a kernel package. |
