Installation of arch

Generally follow the newer guider and installation guild, the steps are:

1.Partition

I use gpt instead of mbr, so the part work is a bit of difficult.

swap partition: Swap partition can be considered at the begining of the installation or at any time of the use of the system later. The method to do this later:

　　gparted a partition: /dev/sda6 for example.

　　mkswap /dev/sda6　　//set up a swap area

　　swapon /dev/sda6　　//use the swap

　To make the swap partition swap to be used at boot, add this line to /etc/fstab

　　/dev/sda2 none swap defaults 0 0

　To check swap partition, type:

　　swapon -s

　　or

　　free -m　　//check swap and ram

commands:　　　parted and gdisk

　　remember to create a 2mb no-filesystem partition for bios_boot. This is what are written in wiki:"If planning to use the GPT partitioned SSD as a boot-disk on a BIOS based system (most systems except Apple computers and some very rare motherboard models with Intel chipset) one may have to create, preferably at the disk's beginning, a 2 MiB partition with no filesystem and with the partition type as BIOS boot or bios_grub partition (gdisk type code EF02) for booting from the disk using GRUB"

Ok, lets go to the essay:

　　First, convert the disk from MBR to GPT.

　　Than use parted or gdisk to generate a no-filesystem 2MB partition with a bios_grub flag.

　　Following, parted a /boot, /var, /, /home partition.

　　Format partition:

　　　　mkfs.ext /dev/sda1

　　see what we have done: lsblk

Partition end.

2.Install base

　　mount partitions on the cdbased system:

　　　　mount /dev/sda1 /mnt　　//boot

　　　　cd /mnt

　　　　mkdir home, var, boot

　　　　mount the other three at these folders.

　　vi /etc/pacman.d/mirrorlist

　　pacstrap -i /mnt base base-devel

　　genfstab -p /mnt >> /mnt/etc/fstab

3.chroot to new system:

　　arch-chroot /mnt

　　vi /etc/hostname　　//write your host name in it. For example, hebi_host　　//can also be like this: #echo hebi_hostname > /etc/hostname

　　ln -s /usr/share/zoneinfo/Asia/Shanghai /etc/localtime

　　vi /etc/locate.gen

　　　　remove '#' before eu-US.UTF-8 UTF-8 and the one before de-DE.UTF-8 UTF-8

　　echo LANG=en_US.UTF-8 > /etc/locale.conf

　　export LANG=en_US.UTF-8

　　hwclock --systohc --utc

　　/*this maybe the auto wired and auto dhcp service:

　　　　pacman -S ifplugd

　　　　cd /etc/network.d

　　　　ln -s examples/ethernet_dhcp

　　　　systemctl enable net-auto-wired.service*/

　　/*this maybe the auto wifi

　　　　pacman -S wireless_tools wpa_supplicant wpa_actiond dialog

　　　　wifi-menu

　　　　systemctl enable net-auto-wireless.service

　　　　vi /etc/conf.d netcfg*/

　　vi /etc/mkinitcpio.conf　　add usb to hook"xxx,xxx,xxx"　　//optional for install on flash disk.

　　mkinitcpio -p linux

　　passwd

　　useradd -m -g users -G wheel ,storage,power -s /bin/bash hebi

　　passwd hebi

　　/*install grub2*/

　　　　# pacman -S grub-bios

　　　　# grub-install --target=i386-pc --recheck /dev/sda

　　　　# cp /usr/share/locale/en\@quot/LC_MESSAGES/grub.mo /boot/grub/locale/en.mo

　　　　to search for other OS:

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

　　/*install syslinux*/

　　　　# pacman -S syslinux ]

　　　　# syslinux-install_update -i -a -m

　　　　vi /boot/syslinux/syslinux.cfg

　　　　　　modefy: LABEL arch ... APPEND root=/dev/sda3 ro

4.umount /var, /home, /boot, /mnt and restart. OK.
