ArchLinux ; Installa #1 Image Download and Preparation

Arch Linux Arch Linux is a Linux distribution. Unlike other distributions, which often perform graphical installation, Arch Linux uses a CUI command line screen to perform the installation process. However, since there is no need to install unnecessary packages, you can create your own environment that is highly flexible, lightweight, and compact. Arch Linux does not have the "version" concept of other distributions. The installation ISO contains only the commands used during the installation process, and the ISO file is updated monthly to ensure that it is always up-to-date. Forte ・Arch Linux does not have the "version" concept that other distributions have ・The installation ISO image contains only the commands used during the installation process, and the ISO file is updated monthly. ・Ability to work with the latest kernel and commands for installation ・Arch Linux allows you to select and install only what you use, so no extra packages are installed. ・Packages are always updated to be nearly up-to-date, so you can use the latest Linux kernel, the latest versions of software, and so on. ・Arch Linux's proprietary package manager, pacman (CUI), takes significantly longer to install packages than other distributions.

ArchLinux ; Installation #2 Disk Partitioning

1. Partitioning the disk on which Arch Linux is installed This time, use gdisk command in UEFI mode and GPT for the partition table. Check current disk information # lsblk NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINTS loop0 7:0 0 693.5M 1 loop /run/archiso/airootfs sda 8:0 0 20G 0 disk sr0 11:0 1 813.3M 0 rom /run/archiso/bootmnt In the above case, a 20 GB virtual HDD was created on VmwareWorkstion, so the SIZE of the sda is set to 20 GB. The sda in the NAME line is the name of the device that represents the entire disk and will be partitioned to this sda. This time, create an EFI partition and a partition for Arch Linux, but not a swap partition. In the past, a partition was created for swap and allocated as swap, but now a "swap file" can be used without a swap partition. A "swap file" is a method of creating a single file of any size for swap and using that area as swap, which can be created, deleted, and resized.

ArchLinux ; Installation #3 Initial settings during installation

Initial setup within the installed system To enter the installed system, use the arch-chroot command. arch-chroot is a script for Arch Linux installation that mounts the system so that the specified path is the root "/". However, after this, only commands in the destination ArchLinux can be used. Commands in the installation media cannot be used. For example, to install a package, use pacman instead of pacstrap. Enter the installed system (/mnt becomes /)
