Ubuntu Server 22.04 LTS (Jammy Jellyfish) released builds
https://cloud-images.ubuntu.com/
https://cloud-images.ubuntu.com/releases/22.04/release/ubuntu-22.04-server-cloudimg-amd64.img
不要被这货的后缀.img所蒙蔽了，实际上是qcow2镜像！
使用qemu-img转换格式: raw, qcow2, qed, vdi, vmdk, vhd
rpm系
deb系
- apt install -y qemu-utils
复制代码
然后转换
- qemu-img convert -f raw -O qcow2 ubuntu-22.04-server-cloudimg-amd64.img ubuntu-22.04-server-cloudimg-amd64.raw
复制代码
具体看这里
Converting between image formats — Virtual Machine Image Guide documentation.mhtml
https://docs.openstack.org/image-guide/convert-images.html
接着安装kpartx
rpm系
deb系
然后挂载镜像
- kpartx -av ubuntu-22.04-server-cloudimg-amd64.raw
复制代码
- mount /dev/mapper/loopX /mnt
复制代码
以实际硬盘分区为准，运行kpartx -av ubuntu-22.04-server-cloudimg-amd64.raw有提示。
改网卡名为eth0，并自动获取dhcpv4、dhcpv6地址
需要改MAC地址为实际的
通过ip addr show获取实际MAC地址
- cat <<EOF> /mnt/etc/netplan/config.yaml
- network:
- version: 2
- renderer: networkd
- ethernets:
- eth0:
- dhcp4: true
- dhcp6: true
- match:
- macaddress: 00:00:00:00:00:20
- set-name: eth0
- EOF
复制代码
改ssh允许root密码登录
- nano /mnt/etc/ssh/sshd_config
复制代码
PermitRootLogin yes
PasswordAuthentication yes
改root密码
获取密码
[[email protected] ~]#
- openssl passwd -1 https://hostloc.com/
复制代码
$1$1UVdmoQe$MKwgVugqOmLxeSo7q7lLo1
设置root密码为“https://hostloc.com/”
root  1$1UVdmoQe$MKwgVugqOmLxeSo7q7lLo1:18849:0:99999:7:::
设置开机启动
狗日的ubuntu云镜像没有主机密钥，别的都有的，不加没办法登录
- cp -f /mnt/usr/lib/systemd/system/rc-local.service /mnt/etc/systemd/system/
复制代码
- cat <<EOF> /mnt/etc/rc.local
- #!/bin/sh -e
- #
- # rc.local
- #
- # This script is executed at the end of each multiuser runlevel.
- # Make sure that the script will "exit 0" on success or any other
- # value on error.
- #
- # In order to enable or disable this script just change the execution
- # bits.
- #
- # By default this script does nothing.
-
- ssh-keygen -A
- exit 0
- EOF
复制代码
- chmod +x /mnt/etc/rc.local
复制代码
至此全部完成基于官方云镜像的最新版系统！
