Gentoo fresh installation

Gentoo fresh installation through Virtualbox and livecd.

Introduction:
Gentoo are very customizable distro compared to others such as ubuntu. You can go easymode and use ubuntu cause ubuntu is for people that dont know how to use or install gentoo. Gentoo is totally free from 3rd party application or commercial.

Note:
You better stick with Gentoo handbook until you know what you doing.
Learn from mistakes. Do it again until you familiar with your basic setting.

Part 1: Partitioning the HDD (This Virtual HDD is 40gb as example and we will be using gparted)

fdisk -l View HDD details
parted -a optimal /dev/sda Configuring HDD
mklabel gpt Make label for HDD
unit Mib This will set metric unit
mkpart primary 1 3 Creating grub partition (1 to 3 is HDD block unit count or ‘size’)
name 1 grub Name it to 'grub’
set 1 bios_grub on Enable the grub
mkpart primary 3 131 Creating boot partition (3 to 131 is HDD block unit count or ‘size’)
name 2 boot Name it to 'boot’
mkpart primary 131 2179 Creating swap partition (131 to 2179 is HDD block unit count or ‘size’)
name 3 swap Swap should be more than 1gb. We use 2gb (2048) as example
mkpart primary 2179 40000 Creating root partition (2179 to 20000 is HDD block unit count or ‘size’)
name 4 rootfs Name it to 'rootfs’
set 2 boot on Enable the boot
quit Quit gparted

Part 2: File System and mount (You can use any filesystem, we just do it simple)

mkfs.vfat /dev/sda1
mkfs.ext2 -L “boot” /dev/sda2
mkswap -L “swap” /dev/sda3
swapon /dev/sda3
free -m
mkfs.ext4 -L “rootfs” /dev/sda4

mount /dev/sda4 /mnt/gentoo Root is on /dev/sda4
mkdir /mnt/gentoo/boot Create boot directory
mount /dev/sda2 /mnt/gentoo/boot Mounting boot partition

Part 3: Set the clock and downloading the stage tarball

date MMDDhhmmYYYY Format is month - day - hour - minutes - year

cd /mnt/gentoo Go into root directory
ping -c 3 gentoo.org Ping the address. I assume you got ur internet running or you will
need to figure it out by using ‘ifconfig’ or ‘net-setup’.
links www.gentoo.org/main/en/mirror.xml Go to website and choose current stage 3 and download
tar xvjpf ‘stage3’ --xattrs Untar the compressed tarball

Part 4: Configuring the make.conf

nano -w /mnt/gentoo/etc/portage/make.conf Open the make.conf and edit few things below
CFLAGS="-march=native -02 -pipe" March native will utilize CPU architecture
MAKEOPTS="-j4" Set the number of ur CPU cores plus 1 or any value
USE=“python icu bindist mmx sse sse2” Set the basic USE flags.
ALSA_CARDS="" Sound Cards. (ex, hda-intel) This are not necessary because new kernel version already know your alsa cards
VIDEO_CARDS=" " Video Cards. (ex, nvidia) Dont put anything yet
INPUT_DEVICES=" " Input Devices. (ex, keyboard) Dont put anything yet

Both VIDEO_CARDS and INPUT_DEVICES are better to be add after successful boot and @world merge to avoid conflict.

When done, press ‘Ctrl + X’ to save and press ‘Y’. And proceed to next step.

Part 5: CHROOTING (Change root) Selecting mirrors is not necessary because it already set by default. Just do the change root (chroot).

cp -L /etc/resolv.conf /mnt/gentoo/etc/
mount -t proc proc /mnt/gentoo/proc
mount --rbind /sys /mnt/gentoo/sys
mount --make-rslave /mnt/gentoo/sys
mount --rbind /dev /mnt/gentoo/dev
mount --make-rslave /mnt/gentoo/dev

chroot /mnt/gentoo /bin/bash
source /etc/profile
export PS1="(chroot) $PS1"
emerge-webrsync Or you can also ‘emerge --sync’ to sync all file

Selecting the right profile. This are important because it will pull all lib and package dependencies depend on what you want to use. KDE, Gnome, Xfce, Plasma, Hardened all have different USE Flags and libs dependencies.
eselect profile list Select profile to use. We will be using desktop for example
eselect profile set X Set the Plasma desktop profile

Part 6: Timezone and Localization

ls /usr/share/zoneinfo View all zone list
ls /usr/share/zoneinfo/‘ur country’ Choose country and state from list
echo “ur country/ur state” > /etc/timezone Save timezone info into /etc/timezone
emerge --config sys-libs/timezone-data Install timezone configuration

nano -w /etc/locale.gen Edit locale.gen and set to 'local’
locale-gen Generate locale
eselect locale list Select appropriate locale
eselect locale set # Set locale

env-update && source /etc/profile && export PS1="(chroot) $PS1" Update the environment

Note:
if occur SYNC setting found in make.conf. warning

comment sync

vi /etc/portage/make.conf
GENTOO_MIRRORS="http://ftp.iij.ad.jp/pub/linux/gentoo/"
SYNC=“rsync://rsync1.jp.gentoo.org/gentoo-portage”

mkdir /etc/portage/repos.conf
cp /usr/share/portage/config/repos.conf /etc/portage/repos.conf/gentoo.conf

Part 7: KERNEL and File system table (fstab)

emerge --ask --verbose sys-kernel/gentoo-sources This will install gentoo sources kernel
emerge -av pciutils usbutils Install required tool to detect pci and usb
emerge genkernel Install kernel

nano -w /etc/fstab There are few things need to be configure here to map your partitions

/dev/sda2	/boot		ext2	noauto,noatime	1 2
/dev/sda4	/		ext4	noatime		0 1
/dev/sda3	none		swap	sw		0 0
/dev/sr0		/mnt/cdrom	iso9660	noauto,user,ro	0 0

This file and drive order/names are very important so the kernel and modules can load properly and Dbus can start its process.
sr0 are cd/dvd drive and iso9660 is its default kernel module. Adding ‘user’ will allow user to mount cd/dvd
When all done, save the configuration press ‘Ctrl + X’ to save press ‘Y’. And proceed to next step.

genkernel --menuconfig all This will open a GUI (Generated User Interface) kernel for customization
Add your hostname in General Setup. When you done, save it to .config
(by default name). Then exit. This will take a while to process.

emerge -av sys-kernel/linux-firmware Apply linux firmware

Part 8: Hostname and DHCP

nano -w /etc/conf.d/hostname Set hostname for "localhost"
ifconfig View networking adapter and adapter name
emerge --ask --noreplace net-misc/netifrc
nano /etc/conf.d/net Configure network adapter to use dhcp on boot. Make
sure adapter name is same from ifconfig
config_enp0s3=“dhcp”

cd /etc/init.d
ln -s net.lo net.enp0s3 Prepares the adapter on boot
ls -lsa View (list) net.lo is redirected to net.enp0s3

nano -w /etc/hosts 127.0.0.1 replace localhost

Part 9: Set root access and hardware clock

passwd password Any password
nano -w /etc/conf.d/hwclock Set UTC to local

Part 10: System tools

emerge -av app-admin/syslog-ng sys-process/cronie sys-apps/mlocate Basic app for admin

rc-update add syslog-ng default
rc-update add cronie default
rc-update add sshd default
emerge -av net-misc/dhcpcd

emerge -av sys-apps/iproute2 sys-apps/net-tools gentoolkit Basic network app (skip this, do it after Plasma desktop load if you need it)

Part 11: System Boot (Grub 2)

emerge -av sys-boot/grub
grub2-install /dev/sda
grub2-mkconfig -o /boot/grub/grub.cfg
exit

ls /mnt/gentoo
umount /mnt/gentoo
shutdown -P now

By now it should be boot and make sure to remove the livecd.

Part 12: Test Booting

login root
cd /
rm /stage3-*.tar.bz2

emerge -uvDNa world This will pull all libs and dependencies needed for the selected profile and also update all the package. This will takes hours depends on your CPU and internet.
It took more than 5 hours for me.

EXTRAS

Part 13: Installing Xorg.

Both VIDEO_CARDS and INPUT_DEVICES will need to be configured again with the appropriate cards and devices.
Depends on your cards, you might need to configure your kernel too because some nvidia provided driver conflicts with nouveu in kernel driver
I will use VIDEO_CARDS=“vesa intel fbdev” and INPUT_DEVICES=“evdev mouse keyboard” as test, because im building this Gentoo in virtual environment.
Add this In /etc/portage/make.conf

VIDEO_CARDS="vesa intel fbdev"
INPUT_DEVICES=“evdev mouse keyboard”

When done, press ‘Ctrl + X’ to save and press ‘Y’.

emerge -av xorg-drivers Install the video cards
emerge -av xorg-server

After its done, you might need to do emerge twm and xterm, just to test if everything are working correctly.

emerge twm xterm

Then do, startx

If everything working as intended, you will get 3 white console. Now you can uninstall the twm and xterm.

emerge --unmerge twm xterm

Part 14: Adding Users

useradd -m -G users,wheel,audio,portage,usb,video -s /bin/bash
passwd

Part 15: Installing Desktop Environment (Plasma)

There are 2 main package for Plasma desktop,

  1. kde-plasma/plasma-meta Everything in Plasma will be installed
  2. kde-plasma/plasma-desktop Only few basic things for loading a plasma desktop
    Just choose either 1 that you need. Then do, emerge.

emerge app-portage/cpuinfo2cpuflags copy the tail after CPU_FLAGS_X86: to CPU_FLAGS_X86 of your make.conf

emerge -av kde-plasma/plasma-meta

You might as well want to install internet browser, file manager, and terminal emulator.

emerge -av kde-apps/konsole kde-apps/konqueror kde-apps/dolphin

Part 16: Configuring boot up and finalizing

nano /etc/env.d/90xsession
add a new line,
XSESSION=“KDE-4”

When done, press ‘Ctrl + X’ to save and press ‘Y’.

nano ~/.xinitrc
add a new line,
exec ck-launch-session dbus-launch --sh-syntax --exit-with-session startkde

When done, press ‘Ctrl + X’ to save and press ‘Y’.

nano /etc/conf.d/xdm
edit the line and add with sddm,
DISPLAYMANAGER=“sddm”

When done, press ‘Ctrl + X’ to save and press ‘Y’.

Add sddm to video group,
usermod -a -G video sddm

/etc/init.d/dbus status Check the dbus status
/etc/init.d/dbus start
rc-update add dbus default

/etc/init.d/consolekit status Check consolekit status
/etc/init.d/consolekit start
rc-update add consolekit default

rc-update add xdm default
/etc/init.d/xdm status

env-update && source /etc/profile
/etc/init.d/xdm start

IF everything working and you follow this guide, it will load the Plasma login screen after you start the xdm. If it doesn’t something is wrong with your step.
Check everything back if it does. Your desktop will be flickering because it still have twm and xterm in the background, under the plasma. You can fix it by doing a reboot after login the plasma.

If it working, all good. You will get the same desktop as im currently using now.

Part 17: Installing ALSA (Advance Linux Sound Architecture), and Pulseaudio
By default, libs and packages needed for sound to working are already pulled in when merging the Plasma desktop. We just need to enable it.

/etc/init.d/alsasound status Check for sound card status
/etc/init.d/alsasound start
rc-update add alsasound boot Set alsasound to run at boot level
alsamixer Adjust the sound level
speaker-test -t wav -c 2 Sound check

Add USE flags “alsa” and “pulseaudio” into /etc/portage/make.conf
emerge -av pavucontrol Pulseaudio volume control. This are very useful application to manage your sound cards
speaker test -t wav -c 2

You should get to hear sound from speaker test. If you dont, open Pulseaudio volume control and select your sound cards and appropriate sound codec.
Don’t use “speaker-test -t wav -c 2” as a root access. Do speaker test as a normal user in another terminal. You will hear sound from the test.

env-update && source /etc/profile

Dispatch-conf and etc-update are tools to help you fix your config files. It will give you an option for each to use the new file, use old file, or let you edit the two files together. If you have a new system that you didn’t customize, typically using the new file is easiest.

Part 18: Last check and booting.
Check everything again and tinkering around with desktop settings.

To fully optimize for browsing internet (Youtube), i recommend to install Firefox and also adobe flash

emerge -av firefox
emerge -av adobe

You need to mount cd/dvd rom (sr0) by yourself if you want to use the drive. Just like mounting a usb memory stick.

mkdir /mnt/cdrom
mount -t iso9660 /dev/sr0 /mnt/cdrom

mkdir /mnt/usb
mount /dev/sdb1 /mnt/usb
