--- type: slide slideOptions: transition: slide --- Arch Linux Installation Workshop === --- # 會場內 Wifi ## ssid: archlinux.tw ## password: since20130818 ---- # 下載 Arch Linux iso + [官方列表](https://archlinux.org/download/) + [archlinux.tw](http://mirror.archlinux.tw/ArchLinux/iso/2022.07.01/) + [交大鏡像](https://archlinux.cs.nycu.edu.tw/iso/2022.07.01/) ---- ## 建立一個虛擬機器 #### QEMU 或其他你熟悉的虛擬機器軟體皆可 ```shell $ qemu-img create -f qcow2 archlinux.cow 32G ``` ---- ## 將 Arch iso 放進虛擬機裡面開機建立 `run.sh` 如下 ```shell #!/bin/sh qemu-system-x86_64 \ -drive file=archlinux.cow,format=qcow2 \ -smp $(nproc) \ -m 16G \ -M q35 \ -device intel-iommu \ -cpu host \ -enable-kvm \ -cdrom archlinux-2022.07.01-x86_64.iso ``` RAM(-m) 和 CPU(-smp) 大小可依據個人需要做調整 ---- ## 第一個選項進入安裝介面 ![](https://i.imgur.com/tzuaW2y.png) --- # 網路設定 ## 虛擬機基本上不需要下面步驟 ---- ## 網路設定 —— 網路介面 ```shell root@archiso ~ # ip a 1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000 link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 inet 127.0.0.1/8 scope host lo valid_lft forever preferred_lft forever inet6 ::1/128 scope host valid_lft forever preferred_lft forever 2: enp0s2: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc fq_codel state UP group default qlen 1000 link/ether 52:54:00:12:34:56 brd ff:ff:ff:ff:ff:ff inet 10.0.2.15/24 metric 100 brd 10.0.2.255 scope global dynamic enp0s2 valid_lft 86283sec preferred_lft 86283sec inet6 fec0::3793:fa93:301c:7db3/64 scope site temporary dynamic valid_lft 86286sec preferred_lft 14286sec inet6 fec0::5054:ff:fe12:3456/64 scope site dynamic mngtmpaddr noprefixroute valid_lft 86286sec preferred_lft 14286sec inet6 fe80::5054:ff:fe12:3456/64 scope link valid_lft forever preferred_lft forever ``` ---- ## 網路設定 —— SETUP ```shell root@archiso ~ # ip link set enp0s2 up ``` ---- ## 網路設定 —— 測試 ```shell root@archiso ~ # ping archlinux.org PING archlinux.org (95.217.163.246) 56(84) bytes of data. 64 bytes from archlinux.org (95.217.163.246): icmp_seq=1 ttl=255 time=319 ms 64 bytes from archlinux.org (95.217.163.246): icmp_seq=2 ttl=255 time=329 ms 64 bytes from archlinux.org (95.217.163.246): icmp_seq=3 ttl=255 time=352 ms ^C --- archlinux.org ping statistics --- 3 packets transmitted, 3 received, 0% packet loss, time 2002ms rtt min/avg/max/mdev = 318.878/333.302/351.935/13.819 ms ``` ---- ## 網路設定 —— 時間 ```shell root@archiso ~ # timedatectl set-ntp true ``` --- ## pacman & makepkg 設定 ---- ## `/etc/makepkg.conf` 可修改 `MAKEFLAGS` 加快套件編譯速度 ```shell=49 #-- Make Flags: change this for DistCC/SMP systems MAKEFLAGS="-j$(nproc)" #-- Debugging flags DEBUG_CFLAGS="-g" DEBUG_CXXFLAGS="$DEBUG_CFLAGS" #DEBUG_RUSTFLAGS="-C debuginfo=2" ``` ---- ## `/etc/pacman.conf` 啟用顏色、平行下載、彩蛋 ```shell=31 # Misc options #UseSyslog Color #NoProgressBar CheckSpace #VerbosePkgLists ParallelDownloads = 10 ILoveCandy ``` ---- ## `/etc/pacman.d/mirrorlist` 鏡像站列表，可加入下面幾組台灣的站點或是直接從 `/etc/pacman.conf` 內作修改 ```shell Server = https://archlinux.cs.nycu.edu.tw/$repo/os/$arch Server = https://mirror.archlinux.tw/ArchLinux/$repo/os/$arch Server = http://archlinux.ccns.ncku.edu.tw/archlinux/$repo/os/$arch Server = https://free.nchc.org.tw/arch/$repo/os/$arch ``` [Mirror Overview](https://archlinux.org/mirrors/) ---- ## 確認可以正常進行同步 ```shell root@archiso ~ # pacman -Syy :: Synchronizing package databases... core 157.8 KiB 877 KiB/s 00:00 [-----------------------------] 100% extra 1712.2 KiB 7.18 MiB/s 00:00 [-----------------------------] 100% community 6.7 MiB 20.4 MiB/s 00:00 [-----------------------------] 100% ``` --- # 硬碟分割、格式化 ---- ## 查看已安裝硬碟 ```shell root@archiso ~ # fdisk -l Disk /dev/sda: 32 GiB, 34359738368 bytes, 67108864 sectors Disk model: QEMU HARDDISK Units: sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk /dev/loop0: 689.79 MiB, 723292160 bytes, 1412680 sectors Units: sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes ``` ---- 本次將安裝在 `/dev/sda` 上，配置如下： + 512M 給 `/boot` + 2G 給 swap + 其餘給 `/` :::success Tips: 也可以另外切一區 `/home` ，方便重灌備份。 ::: ---- 可以用 `cfdisk` 工具方便切割磁碟： ```shell root@archiso ~ # cfdisk /dev/sda ``` 選擇 gpt 後繼續 ![](https://i.imgur.com/x2WGVA7.png) ---- 建立第一個磁區 ![](https://i.imgur.com/k0haaT9.png) ---- 512M 留給 `/boot` ![](https://i.imgur.com/5ip7PN0.png) ---- 2G 的 SWAP ![](https://i.imgur.com/wZKhDbt.png) ---- 剩下就是根目錄 `/` 的 ![](https://i.imgur.com/xJFpZn9.png) ---- 確認好後選擇 `[Write]` 將變更寫入硬碟 ![](https://i.imgur.com/8qQtvgI.png) ---- 按下後要輸入 `yes` 才會確定寫入 ![](https://i.imgur.com/CcFKhjz.png) ---- 成功寫入後下面會有提示，便可以離開此介面 ![](https://i.imgur.com/w0m5cV3.png) ---- 也可以在 Command Line 確認切割結果： ```shell root@archiso ~ # lsblk NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINTS loop0 7:0 0 689.8M 1 loop /run/archiso/airootfs sda 8:0 0 32G 0 disk ├─sda1 8:1 0 512M 0 part ├─sda2 8:2 0 2G 0 part └─sda3 8:3 0 29.5G 0 part sr0 11:0 1 795.3M 0 rom /run/archiso/bootmnt ``` ---- ## 將 partition 做格式化 ```shell root@archiso ~ # mkfs.vfat -F32 /dev/sda1 mkfs.fat 4.2 (2021-01-31) ``` ```shell root@archiso ~ # mkswap /dev/sda2 Setting up swapspace version 1, size = 2 GiB (2147479552 bytes) no label, UUID=20454172-8b24-416d-8f2e-869be9e650dc ``` ```shell root@archiso ~ # mkfs.ext4 /dev/sda3 mke2fs 1.46.5 (30-Dec-2021) Discarding device blocks: done Creating filesystem with 7732736 4k blocks and 1933312 inodes Filesystem UUID: 44a05c6e-65fa-4743-bbb7-1c1bf7d97cd1 Superblock backups stored on blocks: 32768, 98304, 163840, 229376, 294912, 819200, 884736, 1605632, 2654208, 4096000 Allocating group tables: done Writing inode tables: done Creating journal (32768 blocks): done Writing superblocks and filesystem accounting information: done ``` ---- ## 掛載分區 ```shell root@archiso ~ # mount /dev/sda3 /mnt root@archiso ~ # mkdir /mnt/boot root@archiso ~ # mount /dev/sda1 /mnt/boot root@archiso ~ # swapon /dev/sda2 ``` ---- ## 確認掛載情況 ```shell root@archiso ~ # lsblk NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINTS loop0 7:0 0 689.8M 1 loop /run/archiso/airootfs sda 8:0 0 32G 0 disk ├─sda1 8:1 0 512M 0 part /mnt/boot ├─sda2 8:2 0 2G 0 part [SWAP] └─sda3 8:3 0 29.5G 0 part /mnt sr0 11:0 1 795.3M 0 rom /run/archiso/bootmnt ``` --- # 安裝系統 ---- ## 以 `/mnt` 作為根目錄安裝系統 ```shell root@archiso ~ # pacstrap /mnt base base-devel linux linux-firmware vim git ``` ---- ## 若造遇類似 PGP 問題可以先更新 keyring ```shell error: libcap: signature from "David Runge <dvzrv@archlinux.org>" is marginal trust :: File /mnt/var/cache/pacman/pkg/libcap-2.65-1-x86_64.pkg.tar.zst is corrupted (invalid or corrupted package (PGP signature)).
