gentoo diskless installation notes

閒魂

Hostname: Dwarf

Machine config:
K6-2 450Mhz
P5M3A+
SD 320MB (not too enough)
TNT2 M64 32M
eth0: RTL8139 (plug nothing)
eth1: RTL8139
hdd: 50X CDROM
Floppy boot (etherboot)

Installation disc: gentoo min 2005.0
Server prepare: nfs, folder for dwarf's root

server # emerge -av nfs-utils
server # vi /etc/exportfs
add
/home/tftpd/dwarf       192.168.0.0/24(async,rw,no_root_squash,no_all_squash)
server # /etc/init.d/nfs start

暫不提供 dhcp config

Step 1: Boot and start ssh

boot the live cd
livecd # net-setup eth1 # (dhcp)
livecd # passwd
livecd # /etc/init.d/sshd start

Step 2: Mount nfs

livecd # mount 192.168.0.1:/home/tftpd/dwarf /mnt/gentoo/ -o nolock
livecd # mkdir /mnt/gentoo/home
livecd # mount 192.168.0.1:/home /mnt/gentoo/home -o nolock

Step 3: Install very basic file

mkdir boot usr opt var tmp
chmod 1777 /mnt/gentoo/tmp
cd /mnt/gentoo/tmp
wget http://mirror.gentoo.gr.jp/releases/x86/2005.0/stages/x86/stage1-x86-2005.0.tar.bz2
cd ..
tar jxvfp tmp/stage1-x86-2005.0.tar.bz2
wget http://mirror.gentoo.gr.jp/snapshots/portage-latest.tar.bz2
cd usr
tar jxvf ../portage-latest.tar.bz2
cd ../etc
cp make.conf.example make.conf (overwrite)
vi make.conf

Step 4: chroot and compile

cp -L /etc/resolv.conf /mnt/gentoo/etc/resolv.conf
mount -t proc none /mnt/gentoo/proc
chroot /mnt/gentoo /bin/bash
mkdir /usr/local/portage
env-update
source /etc/profile
emerge sync

* An update to portage is available. It is _highly_ recommended
* that you update portage now, before any other packages are updated.
* Please do so and then update ALL of your configuration files.

emerge portage

>>> Stage 1 to stage 2 <<<

cd /usr/portage
scripts/bootstrap.sh -f # (-f = fetch-only mode)
scripts/bootstrap.sh

(~20 hours)

>>> Stage 2 to stage 3 <<<

Add USE "nptl nptlonly" (nptl only optional, I havn't use)

emerge -eavtuD system

(~ over 2 days)

Step 5: Then ... kernel

ln -sf /usr/share/zoneinfo/Asia/Hong_Kong /etc/localtime
emerge gentoo-sources
cd /usr/src/linux
make menuconfig

Step 6: Prepare for network boot 精彩！

server # emerge tftp-hpa syslinux mknbi (dhcp)

server # vi /etc/dhcp/dhcpd.conf

1.         host dwarf {
   
2.                 ddns-hostname "dwarf";
   
3.                 ddns-domainname "idlerlan.local";
   
4.                 filename "tftp:///vmlinuz_dwarf";
   
5.                 option time-servers stdtime.gov.hk;
   
6.                 option root-path "/home/tftpd/dwarf";

Step 7 reboot and install X-window

compile x11-xorg 估計要 200 hours, so use binary

download package cd
mount /tmp/package-x86-2005.0.iso /usr/portage/package -o loop
dwarf # PKGDIR=/usr/portage/package emerge -avK x11-xorg
dwarf # emerge -av icewm mozilla-firefox-bin scim

暫時諗唔到計 cap 圖…

（不過 icewm 又唔係靚，部機又唔係快，cap 唔 cap 都冇關係…）

Mr.Ben

多謝分享, 繼續努力

試試 fluxbox 會唔會快D :-)

呢篇好似冇需要置頂…放在精華讓它可以 search 到就 ok 吧！

始終好小人會咁玩，而且 d hdd 又咁平…甚至 ide->cf + cf 卡都平（除非真係想玩一塊底板 + Network cable/wireless = 一個 linux）

呢個 case 係用 pxe on floppy，很多 onboard lan card 有 pxe boot rom 的，可以 floppy 都不用！如 asus p4p800 我也試過 diskless 了…

順道一提，ram 一定要多，swapping via nfs 絕不是一件好玩的事！

thank you.... now 放返落去...  the only problem is post here get deleted every now and then.... :(
