标签：## 虚拟机 partition bytes dev Linux new 512 Arch
本次介绍在Hyper-V虚拟机上安装Arch Linux的方法，其它虚拟机平台类似。
1. 创建和启动虚拟机
1.1 下载ArchLinux安装镜像
先登录官网下载页面：[https://archlinux.org/download/].
然后根据喜好选择具体的下载链接，比如我选择通过国内网易163下载镜像文件：
[http://mirrors.163.com/archlinux/iso/2022.06.01/archlinux-2022.06.01-x86_64.iso].
1.2 创建虚拟机
新建一个虚拟机，选择Generation 2的UEFI方式启动，接着设置内存2048M，存储50G，配置网卡(安装过程需要联网下载文件)，Installation Options选项中选择加载步骤1.1中下载的ISO文件。
点击完成后，就创建了一个虚拟机，选中虚拟机，鼠标右键选择"Settings -> Security"，禁用"Enable Secure Boot"功能，保存，启动虚拟机。
1.3 测试网络
启动完成之后，就进入了控制台界面，使用ping命令测试网络是否正常。
$ ping www.baidu.com -c 4 PING www.wshifen.com (45.113.192.102) 56(84) bytes of data. 64 bytes from 45.113.192.102 (45.113.192.102): icmp_seq=1 ttl=53 time=131 ms 64 bytes from 45.113.192.102 (45.113.192.102): icmp_seq=2 ttl=53 time=94.0 ms 64 bytes from 45.113.192.102 (45.113.192.102): icmp_seq=3 ttl=53 time=91.1 ms 64 bytes from 45.113.192.102 (45.113.192.102): icmp_seq=4 ttl=53 time=93.1 ms --- www.wshifen.com ping statistics --- 4 packets transmitted, 4 received, 0% packet loss, time 3004ms rtt min/avg/max/mdev = 91.123/102.347/131.195/16.687 ms
2. 分区
2.1 查看分区
$ fdisk -l Disk /dev/sda: 50 GiB, 53687091200 bytes, 104857600 sectors Disk model: Virtual Disk Units: sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 4096 bytes I/O size (minimum/optimal): 4096 bytes / 4096 bytes Disk /dev/loop0: 688.21 MiB, 721641472 bytes, 1409456 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
2.2 创建分区
50G的存储空间，这里分为3个部分，如下表：
| No. | Area | Caps | Fromat |
| 1 | boot | 512M | FAT32 |
| 2 | swap | 4096M | - |
| 3 | / | 45.5G | EXT4 |
## 分区.
$ fdisk /dev/sda

3.2 挂载硬盘
$ mount /dev/sda3 /mnt $ mkdir /mnt/boot $ mount /dev/sd1 /mnt/boot $ swapon /dev/sda2 $ lsblk -a
4. 安装系统
4.1 添加国内源
$ vim /etc/pacman.d/mirrorlist
在原有的Server基础上，增加两个：
Server = http://mirrors.163.com/archlinux/$repo/os/$arch Server = https://mirrors.tuna.tsinghua.edu.cn/archlinux/$repo/os/$arch
保存退出，更新源：
$ pacman -Syy :: Synchronizing package databases... core 156.4 KiB 23.1 KiB/s 00:07 [################################] 100% extra 1717.5 KiB 198 KiB/s 00:09 [################################] 100% community 6.7 MiB 226 KiB/s 00:30 [################################] 100%
4.2 安装系统
$ pacstrap /mnt base linux linux-firmware linux-headers base-devel
根据网速的不同,此过程需要一段不等的时间,我安装的这个版本需要下载558.64 MiB,如果中途出现断网等导致下载的情况,重新执行命令即可.
4.3 生成fstab
$ genfstab -U /mnt >> /mnt/etc/fstab
5. 系统配置
5.1 进入系统
$ arch-chroot /mnt
5.2 增加国内源
$ vim /etc/pacman.d/mirrorlist
增加两个国内源，其它源根据喜好自行添加：
Server = http://mirrors.163.com/archlinux/$repo/os/$arch Server = https://mirrors.tuna.tsinghua.edu.cn/archlinux/$repo/os/$arch
5.3 网络配置
安装网络工具:
$ pacman -S iw wpa_supplicant dialog net-tools networkmanager dhcpcd
安装完成后,进行配置网络:
$ systemctl enable NetworkManager $ systemctl enable dhcpcd
5.4 用户配置
设置root密码:
$ passwd New password: Retype new password: passwd: password updated successfully
添加新用户,示例添加一个名字叫test的新用户:
$ useradd -d /home/test -g root -m -s /bin/bash test $ passed test New password: Retype new password: passwd: password updated successfully
安装sudo:
$ pacman -S sudo vim $ visudo
执行上述命令后,会自动打开/etc/sudoers,定位并编辑如下内容:
## ## User privilege specification ## root ALL=(ALL:ALL) ALL ## 增加新建的test用户 test ALL=(ALL:ALL) ALL ## Uncomment to allow members of group wheel to execute any command ## 去掉注释 %wheel ALL=(ALL:ALL) ALL
5.5 安装Grub和efibootmgr
$ pacman -S grub efibootmgr $ grub-install --target=x86_64-efi --efi-directory=/boot --bootloader-id=ArchLinuxGrub $ grub-mkconfig -o /boot/grub/grub.cfg
5.6 安装基础开发工具
$ pacman -S gcc make bc flex bison git openssh axel unzip bzip2 texinfo binutils patch python3
激活sshd:
$ systemctl enable sshd
5.7 完成安装
[root@archiso /]# exit $ umount -R /mnt $ poweroff
6. 启动系统
在Hyper-V此虚拟机中设置,移除安装镜像*.iso, CPU核心数默认是1个,可以适当增加,之后,启动虚拟机.
启动后的效果:
