3. x64版下载位置：http://mirrors.sohu.com/gentoo/releases/amd64/10.1/livedvd-amd64-multilib-10.1.iso

安装步骤:
1. 分割磁区
2. 格式化分割区
3. 挂载分割区
4. 复制Live DVD Gentoo档案
5. 把环境切到硬碟
6. 修改root密码
7. 安装grub到 mbr
8. 设定、注解与停用服务
9. 复制kernel到 /boot区
10. 修改/etc/fstab
11. 编辑/boot/grub/grub.conf
12. 重开机，退出光碟
13. 完成基础Gentoo Live DVD安装

LiveDVD 光碟开机，不进X-Window开机，加快安装速度

boot: gentoo nox

分割磁区
这里是 boot 100M、SWAP 1G、ROOT 79G，其实 ROOT分割10G就可以了，如果不在安装什么的话！保险一点就是开大一点啰。

格式化分割区

mkfs.ext3 /dev/sda1
mkswap /dev/sda2
mkfs.ext4 /dev/sda3

挂载分割区

swapon /dev/sda2
mount /dev/sda3 /mnt/gentoo
mkdir /mnt/gentoo/boot
mount /dev/sda1 /mnt/gentoo/boot

复制 Live DVD Gentoo文件

cp –apf /mnt/livecd/* /mnt/gentoo

把环境切换到硬盘

chroot /mnt/gentoo /bin/bash
env-update&&source/etc/profile

修改 root 密码

passwd
New password: ******
Retype new password: ******
passwd: password updated successfully

安装 grub 到 mbr

grub
root (hd0,0)
setup (hd0)
quit

注解 /etc/conf.d/local.start 里面全部东西，或用下面的指令清空

cat /dev/null > /etc/conf.d/local.start
rc-update del autoconfig

设定时区

rm /etc/localtime
ln –s /usr/share/zoneinfo/Asia/Taipei /etc/localtime

修改 /etc/fstab

/dev/sda1 /boot ext3 defaults 1 2
/dev/sda2 none swap sw 0 0
/dev/sda3 / ext4 defaults 0 1

复制 kernel 到 /boot区

cp /usr/src/linux/System.map /boot/System.map-genkernel-x86-2.6.30-gentoo-r6
cp /usr/src/linux/arch/i386/boot/bzImage /boot/kernel-genkernel-x86-2.6.30-gentoo-r6
genkernel ramdisk

编辑 /boot/grub/grub.conf 内容如下

default 0
timeout 30
title Gentoo Linux 2.6.30-r6
root (hd0,0)
kernel /boot/kernel-genkernel-x86-2.6.30-gentoo-r6 root=/dev/rm0 real_root=/dev/sda3
initrd /boot/initramfs-genkernel-x86-2.6.30-gentoo-r6

退出环境，重开机，退出光碟

exit
reboot
