# ESXi覆盖安装重置root密码

**一、官方方法**

官方KB说明是通过重新安装来重置root密码。

优点：目前6、7和8的版本都支持这种重置方法

缺点：ESXi主机相关的配置信息全部丢失，就剩内部的虚拟机

1、通过ESXi ISO镜像启动服务器，等待到安装界面，按 **回车** 键继续

2、按 **F11** 键继续安装

3、选择安装磁盘（需要选择以前老的ESXi安装的磁盘），选好按 **回车** 键继续

4、这步非常重要，由于是覆盖安装因此会提示“ESXi and VMFS Found”并给出三个装模式选项，这边要选择第二个模式，按 **回车** 键继续。

第一个升级ESXi并保留数据文件：Upgrade ESXi，preserve VMFS datastore

第二个安装ESXi并保留数据文件：Install ESXi，preserve VMFS datastore

第三个安装ESXi并覆盖数据文件：Install ESXi，overwrite VMFS datastore

5、语言默认即可，按 **回车** 键继续

6、输入新的密码，按 **回车** 键继续

8、按 **回车** 键重启，重启完就是新密码了。

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.chjina.com/it-zhi-shi-ku/xu-ni-hua/vmware/esxi/esxi-fu-gai-an-zhuang-zhong-zhi-root-mi-ma.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
