你可以从任何一个Linux发行版下安装Gentoo。
硬盘安装Gentoo，只要下载一个stage3的tbz2包就行了（你是什么CPU的就下相应的包）.
×注：以下具体的数据都以你自己机器的实际情况为主×
用现有的Linux启动登录至字符界面 （原有Linux启动时root＝/bin/bash参数可不加，经本人试验，完全没问题）
1.首先，打开硬盘的DMA，用事先分好的区来安装Gentoo Linux系统
#hdparm -c 1 -d 1 /dev/hda
我们把root分区格式化为reiserfs 文件系统
#mkreiserfs /dev/hda8 （如果没有mkreiserfs命令，那可能是你没装reiserfsprogs,可从这里下载后编译安装 http://www.namesys.com/pub/reiserfs...gs-3.6.4.tar.gz 或从这里下载
http://rpmseek.com/download/mandrak...l=com&nid=11766 ）
#mkswap /dev/hda10
#swapon /dev/hda10
2.挂装分区到新建的目录：
#mkdir /mnt/gentoo
#mount /dev/hda8 /mnt/gentoo
3.解压stage3.放到gentoo的根分区也就是/mnt/gentoo （假设原stage3放在Mandrake根分区）
#cp /stage3-athlon-1.4_rc2.tbz2 /mnt/gentoo
#cd /mnt/gentoo
#tar -xvjpf stage3--athlon-1.4_rc2.tbz2（我用的是Duron你是什么CPU的就下相应的包）.
）
4.挂装/proc分区以及cp resolv.conf文件到Gentoo
Linux系统）
#mount -o bind /proc /mnt/gentoo/proc
#cp /etc/resolv.conf /mnt/gentoo/etc/resolv.conf
5.进入chroot环境，升级Portage软件列表及全面更新系统
#chroot /mnt/gentoo /bin/bash
#env-update
#source /etc/profile (真正进入Gentoo环境）
#emerge rsync （下载Portage软件列表）
#nano -w /etc/make.conf (编辑make.conf ,优化Portage相关参数，主要是以下几项）
a修改编译针对CPU的编译优化参数
# Host and optimization settings
# ==============================
#
# For optimal performance, enable a CFLAGS setting appropriate for your CPU
#
# -mcpu=<cpu-type> means optimize code for the particular type of CPU without
# breaking compatibility with other CPUs.
#
# -march=<cpu-type> means to take full advantage of the ABI and instrUCtions
# for the particular CPU; this will break compatibility with older CPUs (for
# example, -march=athlon-XP code will not run on a regular Athlon, and
# -march=i686 code will not run on a Pentium Classic.
#
# CPU types supported in gcc-3.2 and higher: athlon-xp, athlon-mp, athlon-4,
# athlon-tbird, athlon, k6, k6-2, k6-3, i386, i486, i586 (Pentium), i686
# (PentiumPro), pentium, pentium-mmx, pentiumpro, pentium2 (Celeron), pentium3,
# and pentium4. Note that Gentoo Linux 1.4 and higher include at least gcc-3.2.
#
# CPU types supported in gcc-2.95*: k6, i386, i486, i586 (Pentium), i686
[1] [2] [3] [4] [5] [6] [7] 下一页
# (Pentium Pro), pentium, pentiumpro Gentoo Linux 1.2 and below use gcc-2.95*
#
# Decent examples:
#
CFLAGS="-mcpu=athlon-tbird -O3 -pipe"
CFLAGS="-march=athlon-tbird -O3 -pipe"（这是我的优化参数，你可以根据自己的CPU类型选择不同的参数，详情请参考下表）
×Safe flags to use for gentoo-1.4
Those flags are for gcc-3.x and alike (mostly gcc-3.0, gcc-3.1.1 and gcc-3.2), you may check which gcc you're using with the following command :
How to know your gcc version
#gcc --version
You can know which CPU you have with the following command :
How to know your CPU type
cat /proc/cpuinfo
This page is for those who don't want to experiment, want a stable system, but still optimized for their processor. Be careful, by using those flags, binaries from your system might not work on another one. So if you compiled with those flags optimized for p4, you cant send a tbz2 or share a hard disk with a friend who only has a pentium MMX.

c emerge Gentoo Linux的最新unstable版本
# Advanced MaSKINg
# ================
#
# Gentoo is using a new masking system to allow for easier stability testing
# on packages. KEYWordS are used in ebuilds to mask and unmask packages based
# on the platform they are set for. A special form has been added that
# indicates packages and revisions that are expected to work, but have not yet
# been approved for the stable set. '~arch' is a superset of 'arch' which
# includes the unstable, in testing, packages. Users of the 'x86' architecture
# would add '~x86' to ACCEPT_KEYWORDS to enable unstable/testing packages.
# '~ppc', '~sparc', '~sparc64' are the unstable KEYWORDS for their respective
# platforms. DO NOT PUT ANYTHING BUT YOUR SPECIFIC ~ARCHITECTURE IN THE LIST.
# IF YOU ARE UNSURE OF YOUR ARCH, OR THE IMPLICATIONS, DO NOT MODIFY THIS.
上一页 [1] [2] [3] [4] [5] [6] [7] 下一页
#
ACCEPT_KEYWORDS="~x86"（去掉ACCEPT_KEYWORDS="~x86"前的注释符即可）
b打开PROZILLA的多线程下载功能，加快下载速度（在做这一步之前应该先emerge prozilla，这样才能用prozilla来下载。如果是stage1，因为没有c++编译器，可以先不emerge prozilla和修改下面这一步，到stage2以后再改。）
# Fetching files
# ==============
#
# If you need to set a proxy for wget or lukemFTP, add the appropriate "export
# ftp_proxy=<proxy>" and "export http_proxy=<proxy>" lines to /etc/profile if
# all users on your system should use them.
#
# Portage uses wget by default. Here are some settings for some alternate
# downloaders -- note that you need to merge these programs first before they
# will be available.
#
# Lukemftp (BSD ftp):
#FETCHCOMMAND="/usr/bin/lukemftp -s -a -o \${DISTDIR}/\${FILE} \${URI}"
#RESUMECOMMAND="/usr/bin/lukemftp -s -a -R -o \${DISTDIR}/\${FILE} \${URI}"
#
# Prozilla (turbo downloader)
FETCHCOMMAND='/usr/bin/proz --no-getch -s ${URI} -P ${DISTDIR}'
(请注意，b和c优化项在执行完emerge -u world系统更新命令前是没有的，你可以把上述的内容cp到make.conf文件里稍做修改即可）
#emerge prozilla(因为stage3解压的基本系统里没有prozilla命令，如果我们要使用多线程下载软件包的话，就必需先把prozilla dwon下来）
#emerge -u world（全面更新系统，需要很长时间）
6.安装编译内核
#emerge gentoo-sources
#cd /usr/src/linux
#make menuconfig
#make dep
#make bzImage
#make modules
#make modules_install
#cp /usr/src/linux/System.map /boot/System.map-2.4.20
#cp /usr/src/linux/arch/i386/boot/bzImage /boot/vmlinuz-2.4.20
（关于2.4内核的详悉配置方法，请参阅以下文章 http://www.tldp.org/linuxfocus/Chin...rticle252.sHtml
）
7.安装vcron和metalog以及update modules
#emerge vcron
#rc-update add vcron default
#emerge metalog
#rc-update add metalog default
#update-modules
8.安装ADSL拨号软件。
#emerge ppp
#USE="-X" emerge rp-pppoe （因为rp-pppoe和xfree 等X软件包存在倚赖关系，我们要先在字符环境下使用，就要用USE="-X" 参数来安装rp-pppoe)
9.设置时区和Host主机名
#cd /usr/share/zoneinfo/Asia
#ln –sf /usr/share/zoneinfo/Asia/Shanghai /etc/localtime
#nano –w /etc/hostname
10.加入文件系统工具(如果是使用ext2或ext3，可以忽略这一步，系统自带了e2fsprogs）
#emerge reiserfsprogs
11.在Gentoo Linux系统里打开硬盘的DMA
#nano -w /etc/conf.d/local.start
在文件末尾加上 hdparm -c 1 -d 1 /dev/hda
12.设置root用户密码
#passwd
13.修改/etc/fstab文件，以符合你实际的分区情况，这是我的fstab文件，参考一下：）
#nano -w /etc/fstab
# <fs> <mountpoint> <type> <opts> <dump/pass>
# NOTE: If your BOOT partition is ReiserFS, add the notail option to opts.
/dev/ROOT / reiserfs noatime 0 0
/dev/SWAP none swap sw 0 0
/dev/cdroms/cdrom0 /mnt/cdrom iso9660 noauto,owner，ro，iocharset=cp936 0 0 0 0
上一页 [1] [2] [3] [4] [5] [6] [7] 下一页
proc /proc proc defaults 0 0
# glibc 2.2 and above expects tmpfs to be mounted at /dev/shm for
# POSIX shared memory (shm_open, shm_unlink). Adding the following
# line to /etc/fstab should take care of this:
# (tmpfs is a dynamically expandable/shrinkable ramdisk, and will use almost no
# memory if not populated with files)
tmpfs /dev/shm tmpfs defaults 0 0
/dev/hda1 /winc vfat defaults,rw,iocharset=cp936 0 0
/dev/hda5 /wind vfat defaults,rw,iocharset=cp936 0 0
dev/hda6 /wine ntfs defaults,rw,iocharset=cp936 0 0
/dev/hda7 /winf ntfs defaults,rw,iocharset=cp936 0 0
#mkdir /iwnc /wind /wine /winf（根据自己机器的情况加载windows分区）
qing兄补充道：
quote:修改/etc/fstab文件很重要的
ROOT
BOOT
SWAP
都换成你具体的分区
在启动时
若出现Activating swap [ok]
这是假相
并没有加载swap分区
要出现
Activating swap xxxxxxxk -swap space [ok]
xxxxxx是具体数字,才是真的加载了swap分区
说这么多的目的是,SWAP很重要
14.配置Grub，以便启动系统。
#nano -w grub.conf （建立Grub启动列表文件）
以下是我的menu.lst
default 0
timeout 30
splashimage=(hd0,7) /boot/grub/splash.xpm.gz
title Mandrake Linux 9.0 (Kernel-2.4.19-16mdk)
root (hd0,8)

initrd (hd0,8) /boot/initrd.img
title Gentoo Linux 1.4 RC2 (Kernel-2.4.20gentoo)
root (hd0,7)
kernel /boot/vmlinuz-2.4.20gentoo ro root=/dev/hda8 hdc=ide-scsi
#cp /usr/share/grub/i386-pc/* /boot/grub (cp升级过的grub的stage文件到/boot/grub目录）
#grub （配置Grub，让Grub写入MBR，管理整个机器里所有系统的启动）
grub> root (hd0,7) （指定root分区位置）
grub> kernel /boot/vmlinuz-2.4.20gentoo ro root=/dev/hda8 hdc=ide-scsi （指定系统内核的位置以及加入其他参数选项）
grub>setup (hd0) （写入MBR）
grub>quit （退出）
15.进入Gentoo Linux字符环境，配置ADSL。
#adsl-setup
//以下是屏幕显示：
Welcome to the Roaring Penguin ADSL client setup. First, I will run some checks on your system to make sure the PPPoE client is installed properly...
Looks good! Now, please enter some information:

输入准备接入互联网的网卡名，如果是缺省的就直接敲回车键。

** Summary of what you entered **
Ethernet Interface: eth0
User name: xxxx //你的用户名
Activate-on-demand: No
DNS: server
Firewalling: NONE
>>> Accept these settings and adjust configuration files (y/n)?
最后，对上述配置进行确认。确认后的配置系统会写入/etc/ppp/pppoe.conf文件，熟练的用户可直接对其进行修改。
拨号
配置完成后，就可以进行拨号了。
#adsl-start
如果屏幕上出现：“... Connected!”就说明拨号成功了。一般而言做到这一步是没什么问题的。这时可以用ifconfig命令查看，结果除了原本有的eth0、lo外又增添了ppp0。
13.安装配置最新的XFree和KDE3
#emerge xfree qt arts
#USE="-gnome -gtk" emerge kdelibs kdebase (去掉gnome和gtk以及多余kde组件的支持,安装最小化的KDE)
#xf86config （检测配置XFree86，根据自己具体配置选择,配置完毕会在/etc/X11/下生成XF86Config ）
#echo "exec startkde" > ~/.xinitrc （让我们直接用startx命令进入KDE而不是原来的twm）
保存修改退出后，用startx命令就可以进入KDE了。
#reboot
OK,Gentoo现在就落户你的硬盘了.Enjoy Your
