gentoo-installation-instructions-guide-short.txt - Created Saturday 07 September 2024

• Download a Gentoo Minimal Install CD (or any suitable copy of linux)
• Boot your computer/VM with it (it should boot to a root prompt and allow networking)
• Create the disk partitions, manually or use a script:
• Create the filesystems, ie ext4:

# mkfs.ext4 /dev/sda1 -L boot
# mkfs.ext4 /dev/sda3 -L gentoo

• Mount the filesystems: (must repeat every reboot)

# mount /dev/sda3 /mnt/gentoo
# mkdir -p /mnt/gentoo/boot (only do once)
# mount /dev/sda1 /mnt/gentoo/boot
# cd /mnt/gentoo

• Download your particular stage3 now:

Choose the right variant, download the right file <https://gentoo.osuosl.org/releases/amd64/autobuilds/> Save it to [/mnt/gentoo,](file:///mnt/gentoo%2C) (using a browser is OK) With the file in [/mnt/gentoo](file:///mnt/gentoo) and from there, Verify the file (if desired), then

• Extract the archive (implied to the current dir):

# tar --xattrs-include='*.*' --numeric-owner -xpf stage3*

• Mount the {proc,sys,dev,run} directories as filesystems:

manual mount commands: (repeat mount script everytime you reboot)

# mount --types 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
# mount --bind /run /mnt/gentoo/run
# mount --make-slave /mnt/gentoo/run

• copy existing DNS resolver over to chroot

# cp /etc/resolv.conf etc

• ping internet to make sure DNS is valid (if not, add some 8.8.8.8 - googleDNS)

# ping gentoo.org

• enter chroot & activate profile

# chroot . /bin/bash
# source /etc/profile

• portage repository download, first sync ( -k to keep)

# emerge-webrsync

• configure Make.conf

# nano /etc/portage/make.conf to add this line CFLAGS (use COMMON var)

• Optimize the CPU arch, -march=native by default very early on, to take effect when building new packages

COMMON_FLAGS="${COMMON_FLAGS} -march=native"  #(place after -O2 -pipe line)

• More Options for Make.conf

#binpkgs - save packages in /var/cache/binpkgs
FEATURES="${FEATURES} buildpkg"

• Set Timezone

# ln -sf /usr/share/zoneinfo/America/New_York /etc/localtime

• Locale

keep the default C english single locale (otherwise add optional ones to /etc/locale.gen first)

# nano /etc/locale.gen
#(uncomment):
en_US ISO-8859-1
en_US.UTF-8 UTF-8
#(add):
C.UTF8 UTF

• NLS / Translations

# don't need international language translations
INSTALL_MASK="/usr/share/locale"
USE="-nls" #(causes rebuilds)

• Install The Kernel

use distribution's premade **sys-kernel/gentoo-kernel-bin** this will install Dracut to make the initramfs and put it with the latest kernel in /boot,

• make sure /boot is mounted and correctly populated

# ls -al /boot

• Install Grub Bootloader (to the MBR on the disk here)

# grub-install /dev/sda

• configure Grub boot menu

# grub-mkconfig -o /boot/grub/grub.cfg

• Gentoo is now installed!

Reboot into your working system. Handbook Part 1 finished! Continue on to read fully at your own leisure: Working With Gentoo = [Handbook:AMD64/Full/Working] Working With Portage = [Handbook:AMD64/Full/Portage]

Continuing on with the system setup: Things to do in Part 2:

• make /etc/fstab

# genfstab

• install two programs for CPU FLAGS customization

# emerge -avt cpuid2cpuflags resolve-march-native

• passwd - set root password (prompts for pwquality)

# passwd                                                                                                                                              

• For DHCP

set up network, /etc/conf.d/net , symlink "ln -s net.enp0s3 net.lo"

# emerge dhcpcd                                                                                                                                       
# nano /etc/conf.d/net                                                                                                                                     
config_eth0="dhcp"
For static IP regular

routes_enp5s0f1="default via 192.168.1.1"                                                                                                             
dns_servers_enp5s0f1="192.168.1.1"

• Query packages

# emerge -avt gentoolkit portage-utils eix wgetpaste                                                                                                         

• SSH

# emerge openssh                                                                                                                                        
# rc-update add sshd                                                                                                                                    
# rc-service sshd start 

Note: openssh can not login as root even with key, must create additional user to log in that way -or- edit /etc/ssh/sshd_config
