    How to install Arch Linux quick - in a tkistic style

Install base system


First, get a latest, fresh ISO image.


Boot.


Load keymap. Typically it will be:
loadkeys us
but it should be already loaded for you on boot.


Partition.
cfdisk /dev/sdX
Making a swap partition is not recommended
unless you are installing it on a notebook.


Format.
mkfs.FORMAT /dev/sdXn
Recommended FORMAT is ext4.


Mount the partition under /mnt.
mount /dev/sdXn /mnt


Edit the /etc/pacman.d/mirrorlist: put your preferred mirror at top.
JAIST was the best in my circumstances. In order to edit easily,
you might want to install vim. You would also use rankmirrors.
Refer to this page.


Install the base packages into your partition.
pacstrap /mnt base base-devel curl git grub openssh screen tmux vim wget zsh zsh-completions


When it's done, generate fstab.
genfstab -p /mnt >> /mnt/etc/fstab


chroot into the partition.
arch-chroot /mnt


Write your hostname.
echo HOSTNAME >> /etc/hostname


Symlink local time zone.
ln -s /usr/share/zoneinfo/Asia/Seoul /etc/localtime


Uncomment locale of your liking from /etc/locale.gen.
Typically it would be en_US.UTF-8.


Generate your locales.
locale-gen


Set locale preferences.
locale > /etc/locale.conf


Set console keymap and font preferences. In /etc/vconsole.conf:
# /etc/vconsole.conf
KEYMAP=us
FONT=lat2-16


Configure /etc/mkinitcpio.conf.
My liking is to change COMPRESSION to cat:
COMPRESSION="cat"


Create an initial RAM disk with:
mkinitcpio -p linux


Set a root password with passwd.


Enable services

Enable and start services you would run. All of these commands should be run
as root.
```shell
sudo systemctl enable sshd
sudo systemctl start sshd
```

From now on, follow if you are not installing your distribution from a machine
different from where it will be distributed (i.e. not on linode). Other than that,
reboot and apply after deploy as needed.
Network Configuration

Configure your network. I personally prefer systemd-networkd. All of these
commands should be run as root.

Configure /etc/systemd/network/PROFILE_NAME.network
(you should have one every NIC).


for static IP:

[Match]
Name=INTERFACE_NAME

[Network]
Address=YOUR.IP.ADDRESS.HERE/CIDR
Address=ANOTHER.IP.ADDRESS.HERE/CIDR
Gateway=GATEWAY.IP.ADDRESS.HERE

for DHCP:

[Match]
Name=INTERFACE_NAME

[Network]
DHCP=yes

;uncomment this section if you want to *not* use received from the DHCP server as the transient hostname.
;[DHCPv4]
;UseHostname=false


Start systemd-resolvd and link resolv.conf for DNS resolution
from DHCP, or if DNS is defined in network files.
sudo systemctl enable systemd-resolved
sudo ln -sf /run/systemd/resolve/resolv.conf /etc/resolv.conf
sudo systemctl start systemd-resolved


Enable and start systemd-networkd.
sudo systemctl enable systemd-networkd
sudo systemctl start systemd-networkd


Check network status.
ip addr
ping -c3 google.com


Install Bootloader

Install your bootloader. I prefer GRUB.


for MBR partitioned disk:
grub-install --target=i386-pc --recheck --debug /dev/sdX
grub-mkconfig -o /boot/grub/grub.cfg


Reboot

Reboot to newly installed system.
```shell
exit
umount -R /mnt
reboot
```

Create new user and add to sudoers


Create a new user for typical use. Using root for
everyday chores are EVIL.
useradd -m -G wheel -s /bin/bash USERNAME


Edit sudoers. Before editing, I recommend you to edit your vimrc for
easy editing, or install sensible.vim.
EDITOR=vim sudo visudo
# visudo
USERNAME ALL=(ALL) NOPASSWD: ALL


If you enabled sshd and configured network, you can use ssh to
work from now on.
Create Swap File

I recommend you use a swap file instead of a swap partition because it is
easier to modify. All of these commands should be run as root.


Create file for use as swap file.
sudo fallocate -l 1024M /swapfile # allocate file for swapfile
sudo chmod 600 /swapfile # set proper permissions
sudo mkswap /swapfile # format swapfile as swap
sudo swapon /swapfile # enable swap


Edit /etc/fstab and add an entry for the swapfile:
# /etc/fstab
/swapfile none swap default 0 0


In case you want to remove swapfile:
sudo swapoff /swapfile
sudo rm -f /swapfile
and remove the entry from /etc/fstab.
If you want to resize swapfile, just remove it and regenerate it without
removing the fstab entry.
When removing or resizing swapfile, note that swap is managed by systemd and
will be re-enabled by it after some time.
Install zsh

Because we installed zsh on system install, we do not have to install the
package. However, I will install oh-my-zsh for ease of configuration
and themes.


Install oh-my-zsh.
curl -L http://install.ohmyz.sh | sh


Automatic chsh is likely to fail, so you have to do it for yourself.
chsh # authorize and type zsh on prompt


Edit ~/.zshrc and change oh-my-zsh theme. I prefer agnoster, which is
flavored with powerline-patched fonts and solarized colors. I recommend you to
install powerline-patched fonts such as Source Code Powerline if you are
going to use agnoster.
# ~/.zshrc
ZSH_THEME="agnoster" # it should be residing on top, you should modify it.


Editing ~/.zshrc, change your $EDITOR environmental variable and alias:
# ~/.zshrc
export EDITOR="vim"
alias vi="vim"


Editing ~/.zshrc, enable keypad by appending:
# ~/.zshrc
# Keypad
# 0 . Enter
bindkey -s "^[Op" "0"
bindkey -s "^[Ol" "."
bindkey -s "^[OM" "^M"
# 1 2 3
bindkey -s "^[Oq" "1"
bindkey -s "^[Or" "2"
bindkey -s "^[Os" "3"
# 4 5 6
bindkey -s "^[Ot" "4"
bindkey -s "^[Ou" "5"
bindkey -s "^[Ov" "6"
# 7 8 9
bindkey -s "^[Ow" "7"
bindkey -s "^[Ox" "8"
bindkey -s "^[Oy" "9"
# + -  * /
bindkey -s "^[Ok" "+"
bindkey -s "^[Om" "-"
bindkey -s "^[Oj" "*"
bindkey -s "^[Oo" "/"


Change into zsh by:
exec zsh


Relax on the couch and drink a glass of your favorite drink

You now have installed Arch Linux, tkistic style. Now go on and install other
stuff you would use, such as:

Edit vimrc.
Edit .tmux.conf.
Install rvm.
Install pyenv.
Install mkvirtualenv.
Install powerline.
and many other geeky things!
