阿新 • • 發佈:2021-06-30
系統環境:ubuntu20.04
下載ubuntu-20.04.2-live-server-amd64.iso
wget https://releases.ubuntu.com/20.04/ubuntu-20.04.2-live-server-amd64.iso
掛載系統到/mnt下
sudo mount /home/www/ubuntu-20.04.2-live-server-amd64.iso /mnt
拷貝目錄&檔案
拷貝/mnt目錄中的所有內容到/home/www/ubuntu/目錄下
mkdir -p /home/www/ubuntu/
cp -rf /mnt/* /mnt/.disk/ /home/www/ubuntu/
所需自動部署檔案
資料:
- https://ubuntu.com/server/docs/install/autoinstall
- https://ubuntu.com/server/docs/install/autoinstall
user-data檔案:
相關引數參考:
- https://ubuntu.com/server/docs/install/autoinstall-reference
- 可以手動安裝一個系統來獲取user-data檔案
手動安裝好系統後,這個檔案就是/var/log/installer/autoinstall-user-data,user-data檔案
#檢視 cat /var/log/installer/autoinstall-user-data
適當進行修改如對磁碟分割槽大小修改
原完整檔案:

對儲存部分進行了修改
#刪除了磁碟序列號引數
serial: VBOX_HARDDISK_VB8c6ac1fe-c81d121d,
#修改磁碟容量(大小為byte),避免出現磁碟總容量不一樣導致的自動安裝錯誤
{device: disk-sda, size: 53687091200, wipe: superblock, flag: '', number: 2,
修改後完整檔案

meta-data檔案:
cat > meta-data << EOF

EOF
檔案拷貝
將meta-data 、user-data檔案拷貝到/home/www/ubuntu/目錄下
修改引導配置檔案
檔案路徑:
/home/www/ubuntu/isolinux/txt.cfg
原檔案:
default live
label live
menu label ^Install Ubuntu Server
kernel /casper/vmlinuz
append initrd=/casper/initrd quiet ---
label hwe-live
menu label ^Install Ubuntu Server with the HWE kernel
kernel /casper/hwe-vmlinuz
append initrd=/casper/hwe-initrd quiet ---
label memtest
menu label Test ^memory
kernel /install/mt86plus
label hd
menu label ^Boot from first hard disk
localboot 0x80
修改後檔案:
default live
label live
menu label ^Install Ubuntu Server
kernel /casper/vmlinuz
append initrd=/casper/initrd quiet autoinstall ds=nocloud;s=/cdrom/ ---
label hwe-live
menu label ^Install Ubuntu Server with the HWE kernel
kernel /casper/hwe-vmlinuz
append initrd=/casper/hwe-initrd quiet ---
label memtest
menu label Test ^memory
kernel /install/mt86plus
label hd
menu label ^Boot from first hard disk
localboot 0x80
配置完成。
打包成iso映象檔案
進入/home/www/目錄執行如下命令對ubuntu/目錄進行打包
#安裝mkisofs
sudo apt install mkisofs -y
sudo mkisofs -R -J -T -v -no-emul-boot -boot-load-size 4 -boot-info-table -b isolinux/isolinux.bin -c isolinux/boot.cat -o auto-ubuntu-20.04.4-server-amd64.iso ubuntu/
- 會在/home/www/目錄下生成auto-ubuntu-20.04.4-server-amd64.iso檔案
- 就可以使用該映象檔案進行自動安裝了
測試通過環境:
- virtualbox
- 打包環境系統:ubuntu20.04
- 軟體:mkisofs
