Changing a forgotten root password on an ESX/ESXi host (1317898) | VMware KB
How to Reset Forgotten VMware ESXi Root Password with Ubuntu Live CD

如果忘了 ESXi root 密碼

依官方的說法，唯一的方式是重新安裝。

[@more@]解決方式：
1. 找一片 LiveCD，使用 LiveCD 光碟開機

2. 選擇 應用程式 / 系統工具 / MATE 終端機

3. 查看硬碟分割
     $ sudo fdisk -l

檔案在 /dev/sda5

4. 建立掛載目錄
    $ sudo mkdir /mnt/sda5

5. 掛載分割區
    $ sudo mount /dev/sda5 /mnt/sda5

6. 列出檔案
    $ ls /mnt/sda5

7. 複製檔案到使用者目錄
    $ cp /mnt/sda5/state.tgz ~

8. 目錄切換回使用者根目錄
    $ cd ~

9. 解壓縮
    $ tar xvzf state.tgz
    $ tar xvzf local.tgz

10. 修改 etc/shadow
      $ vi etc/shadow

11. 把第一個 : 和第二個 : 之間的字元刪除

12. 刪除原檔
      $ rm -rf local.tgz state.tgz

13. 把 etc 目錄壓縮成 local.tgz
      $ tar czf local.tgz etc

14. 把 local.tgz 壓縮成 state.tgz
      $ tar czf state.tgz local.tgz

15. 刪除原檔
      $ sudo rm -rf /mnt/sda5/state.tgz

16. 複製修改好的檔案回原目錄
      $ sudo cp state.tgz /mnt/sda5

17. 卸載目錄
      $ sudo umount /mnt/sda5

18. 重新啟動電腦

19. 按 F2 進入設定

20. 密碼不用輸入

21. 選擇 Configuration Password，可以看出來目前密碼還未設定

22. 設定新的密碼，要注意的是，這裡的密碼要求比較高，不像在安裝時，設定密碼強度要求比較寬鬆

23. 設定成功！

# 3 = thin  (隨著使用量而增加硬碟大小，達到設定上限時就不會在增加)
# 4 = eagerzeroedthick  (一次給足全部的硬碟大小，全部初始化可直接使用)

Usage: /opt/ghettovcb/bin/ghettoVCB-restore.sh -c [VM_BACKUP_UP_LIST] -l [LOG_FILE] -d [DRYRUN_DEBUG_INFO]

OPTIONS:
   -c     VM backup list
   -l     File ot output logging
   -d     Dryrun/Debug Info [1|2]

(e.g.)

Output will go to stdout
        /opt/ghettovcb/bin/ghettoVCB-restore.sh -c vms_to_restore

虛擬機器不用先關機，ghettoVCB.sh 會先為虛擬機器建立快照，然後進行備份，當備份完成之後會刪除快照。

1.下載 ghettoVCB

2. 上傳到 資料存放區

3. 開啟 ESXi 伺服器可安裝非原廠的額外套件
[root@esxi:~] esxcli software acceptance set –level=CommunitySupported
Host acceptance level changed to ‘CommunitySupported’.

4. 進行安裝 ghettoVCB，似乎沒有進行第 3 步驟，也可以進行安裝

6. 建立 log 檔存放目錄
[root@esxi:~] mkdir /vmfs/volumes/ST500G/ghettoVCB_log

7. 修改 /opt/ghettovcb/bin/ghettoVCB.sh
[root@esxi:~] vi /opt/ghettovcb/bin/ghettoVCB.sh
找到
    #if no logfile then provide default logfile in /tmp
    if [[ -z “${LOG_OUTPUT}” ]] ; then
        LOG_OUTPUT=”/tmp/ghettoVCB-$(date +%F_%H-%M-%S)-$$.log”
        echo “Logging output to “${LOG_OUTPUT}” …”

修改成
    #if no logfile then provide default logfile in /tmp
    if [[ -z “${LOG_OUTPUT}” ]] ; then
        LOG_OUTPUT=”//vmfs/volumes/ST500G/ghettoVCB_log/ghettoVCB-$(date +%F_%H-%M-%S)-$$.log”

Usage: ghettoVCB.sh [options]

OPTIONS:
   -a     Backup all VMs on host(備份所有的 VM)
   -f     List of VMs to backup(備份清單中的 VM，一行一個 VM)
   -m     Name of VM to backup (overrides -f)(備份 VM)
   -c     VM configuration directory for VM backups
   -g     Path to global ghettoVCB configuration file(ghettoVCB.conf 設定檔位置)
   -l     File to output logging(log 檔位置)
   -w     ghettoVCB work directory (default: /tmp/ghettoVCB.work)
   -d     Debug level [info|debug|dryrun] (default: info)

(e.g.)

Backup VMs stored in a list
        /opt/ghettovcb/bin/ghettoVCB.sh -f vms_to_backup

Backup a single VM
        /opt/ghettovcb/bin/ghettoVCB.sh -m vm_to_backup

Backup all VMs residing on this host
        /opt/ghettovcb/bin/ghettoVCB.sh -a

Backup all VMs residing on this host except for the VMs in the exclusion list
        /opt/ghettovcb/bin/ghettoVCB.sh -a -e vm_exclusion_list

Backup VMs based on specific configuration located in directory
        /opt/ghettovcb/bin/ghettoVCB.sh -f vms_to_backup -c vm_backup_configs

Backup VMs using global ghettoVCB configuration file
        /opt/ghettovcb/bin/ghettoVCB.sh -f vms_to_backup -g /global/ghettoVCB.conf

Output will log to /tmp/ghettoVCB.log (consider logging to local or remote datastore to persist logs)
        /opt/ghettovcb/bin/ghettoVCB.sh -f vms_to_backup -l /vmfs/volume/local-storage/ghettoVCB.log

Dry run (no backup will take place)
        /opt/ghettovcb/bin/ghettoVCB.sh -f vms_to_backup -d dryrun
