Simple Arch Set Up
 
Edit: added simple stateful firewall setup using iptables, with info from archwiki

I had a need to install a minimal system -- and being the way I am, I created a document on how to do it. Then I ended up installing it on my laptop, to offer a friendly desktop. So, here is a step by step, sort of copy and paste guide to installing Arch on a laptop with intel wireless and video.

Anything you don't understand can be quickly googled im sure.

Code:

# <boot to usb/cd whatever>

#
# bring up wireless networking
#

ip link set wlan0 up
wifi-menu wlan0

#
# partition disks and mount
#

fdisk /dev/sda
        new, primary, 20g, bootable
        new, primary, 1024m, type, swap
        new, primary, all
        write, quit
mkfs.ext4 /dev/sda1
mkfs.ext4 /dev/sda3
mkswap /dev/sda2
swapon /dev/sda2
mount /dev/sda1 /mnt
mkdir /mnt/home
mount /dev/sda3 /mnt/home

#
# for pacman to work, change siglevel to TrustAll
# bootstrap the new drives, generate an fstab based
# on it
#

# trust all packages -- do not verify package signatures
# fyi: its better to leave package signature requirements enabled

vi /etc/pacman.conf (TrustAll)
pacstrap /mnt base base-devel
genfstab -p /mnt > /mnt/etc/fstab

#
# chroot into new system...
#

arch-chroot /mnt

#
# language and region settings required
#

vi /etc/locale.gen
        uncomment en_US-UTF line
echo LANG=en_US.UTF-8 > /etc/locale.conf
export LANG=en_US.UTF-8
ln -s /usr/share/zoneinfo/US/Eastern /etc/localtime
locale-gen

#
# set hostname, enable dhcp on eth0 interface
# make pacman change to TrustAll again
#

echo ArchTerminal > /etc/hostname
vi /etc/hosts
        ArchTerminal 127.0.0.1
echo ArchTerminal > /etc/hostname
vi /etc/rc.conf
        interface=eth0
vi /etc/pacman.conf
        TrustAll

#
# install packages required for rest of installation
# up to reboot, restart wireless to make config file
#
       
pacman -S wireless_tools netcfg wpa_supplicant\
        wpa_actiond dialog dhclient grub-bios os-prober
vi /etc/rc.conf
        # add these to the DAEMONS
        net-auto-wireless @ntpdate dbus
wifi-menu

#
# add intel915 support to boot, run mkinitcpio
# create grub config, install grub to mbr on new drive
#

# for intel915 support
vi /etc/mkinitcpio.conf
        MODULES="i915"
# standard stuff

#

# all drives and reboot into new system
#

exit
umount /mnt/home
umount /mnt

#

I haven't yet tried Arch, but if I do so at some point I will be sure to refer to this document. Thank you for sharing it with the community! :)

Nice one. Thought about putting it into the LQ Wiki or the Articles section?

EDDY1 09-17-2012 11:30 PM

Great tutorial it seems much easier than the arch beginners guide also wouldn't take 2 days to figure out.
Also you didn't confuse me with /mnt/boot like the beginners guide did.
On my first try I ended up with 2 entries in fstab same partition, / & /boot.

Some comments from a long time archlinux user :

- if you want to use suspend / hibernate , the swap size is to small
- a separate /boot does have advantages
- this guide won't work for a laptop with (U)EFI boot, or with a HDD/SSD bigger then 2 TB
- better put the unsecure desktop in BOLD CAPITALS
using TrustAll is equivalent to not using package signing, and arch has been heavily criticised in the past for not having package signing.

- AUR packages are unsupported, and the PKGBUILD should be reviewed before running makepkg. maybe add a 'vi PKGBUILD' ?

- maybe add something that copy/paste from an internet document without understanding what the commands do is very bad practice

Thank you. I just hope it helps people get started faster, and helps their over-all enjoyment of Arch linux.

I had not. But, I'll see what I can do. Thanks for the suggestion Tobi.

Im glad you are using the experience to learn. Its a fascinating distribution. Good luck in the future.

Good information -- advanced users will be glad to see this additional setup mentioned.

Please read the last sentence of the intro w/r/t understanding. I put it in bold to make it easier to read.

Thanks everyone!
