Arch Installation

Installation

1. Partion a disk

fdisk /dev/sda
d # Delete Partitions
p # List Partitions
n # Create Partitions
w # Execute changes

2. Make filesystems

mkfs.ext4 /dev/sda2
mkfs.fat -F32 /dev/sda1

3. Mount Partitions

mount /mnt /dev/sda2
mkdir /mnt/boot
mount /mnt/boot /dev/sda1

4. Connect a WiFi

  • First, if you do not know your wireless device name, list all Wi-Fi devices:
[iwd]# device list
  • Then, to scan for networks:
[iwd]# station device scan
  • You can then list all available networks:
[iwd]# station device get-networks
  • Finally, to connect to a network:
[iwd]# station device connect SSID

5. Install base

pacstrape base base-devel linux linux-firmware vi networkmanager grub efibootmgr

6. Generate /etc/fstab file

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

Chroot into new install

  • Set timezone
ln -sf /usr/share/zoneinfo/America/New_York /etc/localtime
  • Enable synchronizing
timedatectl set-ntp true
  • Autostart NewworkManager
systemctl enable NetworkManager
  • Install GRUB to target partition
grub-install --target=x86_64-efi --efi-directory=/boot
  • Generation GRUB configuration file
grub-mkconfig -o /boot/grub/grub.cfg
  • Set the root password
passwd
  • Add a new user
useradd -m username
  • Set new user password
passwd username
  • Add user to groups
usermod -aG wheel,audio,video,optical,storage username
  • Add locale information
vim /etc/local.gen uncomment en_US
  • Run locale generation
local-gen
  • Add locale information
vim /etc/locale.conf add LANG=en-US.UTF

vim /etc/hostname

First boot

  • run visudo, uncomment wheel group to allow new user sudo permission

  • enable ZRAM.

    • Install zram-generator using one of the methods listed above.
    • Create a zram-generator.conf config file. 
      # /etc/systemd/zram-generator.conf
[zram0]
zram-size = ram / 2

A zram device will be created for each section. No actual configuration is necessary (the default of zram-size = min(ram / 2, 4096) will be used unless overriden), but the configuration file with at least one section must exist.
Mount points

# /etc/systemd/zram-generator.conf
[zram1]
mount-point = /var/tmp
This will set up a /dev/zram1 with ext2 and generate a mount unit for /var/tmp.
    • Run systemctl daemon-reload to create new device units.
    • Run systemctl start /dev/zram0 (adjust the name as appropriate to match the config).
    • Call zramctl or swapon to confirm that the device has been created and is in use.

  • enable eriodic TRIM, The util-linux package provides fstrim.service and fstrim.timer systemd unit files. Enabling the timer will activate the service weekly

1. NetworkManager add new WiFi

  • Adding a Wi-Fi Connection To view the available Wi-Fi access points, issue a command as follows:
  ~]$ nmcli dev wifi list
    SSID            MODE  CHAN  RATE     SIGNAL  BARS  SECURITY
    FedoraTest     Infra  11    54 MB/s  98      ▂▄▆█  WPA1
    Red Hat Guest  Infra  6     54 MB/s  97      ▂▄▆█  WPA2
    Red Hat        Infra  6     54 MB/s  77      ▂▄▆_  WPA2 802.1X
  * Red Hat        Infra  40    54 MB/s  66      ▂▄▆_  WPA2 802.1X
    VoIP           Infra  1     54 MB/s  32      ▂▄__  WEP
    MyCafe         Infra  11    54 MB/s  39      ▂▄__  WPA2
  • To create a Wi-Fi connection profile with static IP configuration, but allowing automatic DNS address assignment, issue a command as follows:
  ~]$ nmcli con add con-name MyCafe ifname wlan0 type wifi ssid MyCafe \
  ip4 192.168.100.101/24 gw4 192.168.100.1
  • To set a WPA2 password, for example “caffeine”, issue commands as follows:
  ~]$ nmcli con modify MyCafe wifi-sec.key-mgmt wpa-psk
  ~]$ nmcli con modify MyCafe wifi-sec.psk caffeine
  • To change Wi-Fi state, issue a command in the following format:
  ~]$ nmcli radio wifi [on | off ]

Changing a Specific Property

  • To check a specific property, for example mtu, issue a command as follows:
  ~]$ nmcli connection show id 'MyCafe' | grep mtu
  802-11-wireless.mtu:                     auto
  • To change the property of a setting, issue a command as follows:
  ~]$ nmcli connection modify id 'MyCafe' 802-11-wireless.mtu 1350
  • To verify the change, issue a command as follows:
  ~]$ nmcli connection show id 'MyCafe' | grep mtu
  802-11-wireless.mtu:                     1350

Note that NetworkManager refers to parameters such as 802-3-ethernet and 802-11-wireless as the setting, and mtu as a property of the setting. See the nm-settings(5) man page for more information on properties and their settings.
