# Arch install

## First steps

### Font in the console

~~~
setfont ter-128n
~~~

### Connecting to WiFi

~~~
iwctl
iwctl > device list
iwctl > station <device> scan
iwctl > station <device> get-networks
iwctl > station <device> connect <name_point>
~~~

### Time synchronization

~~~
timedatectl set-ntp true
timedatectl status
~~~

## Preparing the file system

~~~
fdisk /dev/sda
~~~

### Creating a partition table

~~~
GPT: fdisk > g
DOS: fdisk > o
~~~

### Section structure

~~~
UEFI:
/dev/sda1 - swap (6G)
/dev/sda2 - boot (512m)
/dev/sda3 - btrfs @,@home (all free)
~~~

### DOS:

~~~
/dev/sda1 - swap (6G)
/dev/sda2 - btrfs @,@home (all free)
~~~

### Creating sections

~~~
fdisk > n
~~~

### Specifying the types of sections

~~~
swap: fdisk > t > Linux swap
boot: fdisk > t > EFI
~~~

### Creating file systems (UEFI)

~~~
swap: mkswap /dev/sda1
boot: mkfs.vfat /dev/sda2
btffs: mkfs.btrfs -L "Arch" /dev/sda3
~~~

### Connect SWAP

~~~
swapon /dev/sda1
~~~

### Creating partitions BTRFS

~~~
mount /dev/sda3 /mnt
btrfs subvolume create /mnt/@
btrfs subvolume create /mnt/@home
mkdir /mnt/@/{boot,home}
umount -R /mnt
~~~

### Mounting partitions

~~~
mount -o subvol=/@,ssd,noatime,compress=lzo,space_cache=v2,discard=async /dev/sda3 /mnt
mount -o subvol=/@home,ssd,noatime,compress=lzo,space_cache=v2,discard=async /dev/sda3 /mnt/home
mount /dev/sda2 /mnt/boot
~~~

## Configere system

### Sorting mirrors for installing packages

~~~
reflector -c Russia -c Belarus -a 5 --sort rate --save /etc/pacman.d/mirrorlist
~~~

### Install base packages

~~~
pacstrap /mnt base linux linux-firmware base-devel btrf-progs dhcpcd iwd vim terminus-font
~~~

### Generating a partition mount file

~~~
genfstab -U /mnt >> /mnt/etc/fstab
~~~

### Change root dir

~~~
arch-chroot /mnt
~~~

### Change password

~~~
passwd
~~~

### Internet Activation

~~~
systemctl enable dhcpcd
systemctl enable iwd
~~~

### We set the time zone and synchronize the time

~~~
ln -sf /usr/share/zoneinfo/Europe/Moscow /etc/localtime
hwclock --systohc --utc
~~~

### Name host

~~~
echo arch > /etc/hostname
~~~

### Settings hosts

~~~
vim /etc/hosts
--
127.0.0.1   localhost
::1         localhost
127.0.1.1   arch.localdomain    arch
~~~

### Generating locales

~~~
vim /etc/locale.gen
locale-gen
~~~

### Install locale

~~~
vim /etc/locale.conf
-->
LANG=en_US.UTF-8
LANGUGE=en_US
LC_ALL=C
LC_COLLATE=C
~~~

### Settings console

~~~
vim /etc/vconsole.conf
-->
KEYMAP=us
FONT=ter-128n
~~~

#### BTRFS

~~~
vim /etc/mkinitcpio.conf
-->
MODULES=(btrfs)
~~~

### Editing hooks

~~~
vim /etc/mkinitcpio.conf
-->
HUKS=(...keymap)
~~~

### Creating the initial environment

~~~
mkinitcpio -P
~~~

### Installing the loader

~~~
pacman -S grub
grub-install /dev/sda

-- Если UEFI:
pacman -S efibootmgr
grub-install --efi-directory=/boot

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

## Completion

~~~
exit
umount -R /mnt
reboot
~~~
