Gentoo is a source-based linux distribution.source-based means every application is compiled locally.

You can download a copy of gentoo Here

To install gentoo you will need to create a bootable LiveCD or LiveUSB.

There are many ways one could create a LiveCD or LiveUSB, but that is outside of the scope of Gentoo Installation

Virtual Machine Setup

If you want to set up Gentoo within a virtual machine you will need at least:

Around 512MB to 1GB of RAM
At least 10GB HDD
Networking features enabled

And preferably multiple cores on an x86_64 processor

Hard Drive Setup

  ls /dev | grep sd
  cfdisk /dev/sda

cfdisk will then bring you into an ncurses gui.

Use cfdisk to:

Create 100MB Partition Bootable at the Beginning
Create 2048MB Partition at the beginning
Create remaining free space partition at the beginning

Choose to Write tables to disk, and then exit.



mkfs.ext2 /dev/sda1
mkswap /dev/sda2
mkfs.reiserfs /dev/sda3
mount -t reiserfs /dev/sda3 /mnt/gentoo ; cd /mnt/gentoo
wget http://gentoo.arcticnetwork.ca/releases/x86/current-stage3/stage3-i686-20110614.tar.bz2

for the below line, you can simply press the TAB button after stage3 and it will automatically complete the command, just press enter to confirm it

tar xvpjf stage3*
swapon /dev/sda2
cp /etc/resolv.conf /mnt/gentoo/etc/resolv.conf

Okay, now you've set up your hard drives, downloaded a copy of gentoo on your live environment, and copied resolv.conf over. Before continuing make sure you can access the internet.

you can test this by pinging google:

ping -c 2 google.com

if it isn't working, try the following:

you might need to do this each time you reboot

   
    ifconfig eth0 down && ifconfig eth0 up
    dhcpcd eth0

Base installation and Configuration

Remember the number in the output of this command, you will need it later.

grep -ci "processor" /proc/cpuinfo

Download & Extract portage to /mnt/gentoo/usr/

   cd /mnt/gentoo/usr/
   wget http://gentoo.arcticnetwork.ca/releases/snapshots/current/portage-latest.tar.bz2
   tar xvjf portage-latest.tar.bz2

Open make.conf in nano.

   cd /mnt/gentoo/etc/
   nano make.conf

Modify make.conf as follows:

Do not modify the CHOST, this will cause problems!

 CFLAGS="-fstack-protector-all -fforce-addr -Os -pipe -march=native"
    CXXFlags="${CFLAGS}"


    FEATURES="metadata-transfer sandbox candy parallel-fetch"

    USE="gtk truetype postgres freetype jpg jpeg png gif imap ttf winscp passwd scp X gnutls mysql v4l2 extras lisp threads ithreads acpi bash-completion bzip2 crypt cracklib css ctype apache2 curl curlwrappers dbus encode ftp gcj gd geoip udev ipv6 lua ncurses nsplugin python readline sockets socks5 sqlite sse sse2 ssl suid unicode vim-syntax xml php perlsuid"

    #Replace Y with the output of the grep command and X with the returned number +1. For one core, you'd have "--jobs=1" and "-j2".

    MAKEOPTS="-jX -s"
#   Only use the below line if you have a multicore CPU or multiple processors
#   EMERGE_DEFAULT_OPTS="--jobs=Y --load-average=1.5"
    PORTAGE_NICENESS="12"

CHROOT

You will have to return to this part each time you reboot until the installation is finished.

   mount /dev/sda3 /mnt/gentoo
   swapon /dev/sda2
   mount /dev/sda1 /mnt/gentoo/boot
   mount -o bind /dev /mnt/gentoo/dev
   mount -t proc none /mnt/gentoo/proc
   chroot /mnt/gentoo /bin/bash --login

You only need to run gcc-config the first time around.

   gcc-config 1

   env-update

The following line helps remember where you are.

   export PS1="chroot) $PS1"

Installing Software

This requires a working internet connection, test your connection with ping:

 ping -c 2 google.com

If you cannot ping, try issuing the following:

echo nameserver 4.2.2.1 > /etc/resolv.conf
echo nameserver 4.2.2.2 >> /etc/resolv.conf

Sync your repos:

 emerge -q --sync

if it tells you that an update to portage is availible then do the following

 emerge -q portage

otherwise, continue from here:

   emerge -q axel

Let's edit make.conf again:

   nano -w /etc/make.conf

   # put this at the bottom of make.conf
   FETCHCOMMAND="/usr/bin/axel -n 8 -o /\${DISTDIR}/\${FILE} -a \${URI}"
   RESUMECOMMAND="/usr/bin/axel -n 8 -o /\${DISTDIR}/\${FILE} -a \${URI}"

   # ^x Y Enterto save and quit

   emerge -qN pciutils coreutils baselayout hardened-sources world
