VMware ESXi5忘记登录密码解决办法

很久没有登录ESXi5了，今天登录发现忘记密码了：

网上搜索到的方法都是使用linux其他版本的镜像的恢复模式来重置密码（尝试过了，ESXI自己的镜像没有恢复模式）。于是使用现有的Ubuntu镜像来操作。

1、挂载Ubuntu镜像，然后以cd方式启动虚拟机

2、按F5进入恢复模式

3、选择try Ubuntu

4、打开终端，exsi默认的存储在/dev/sda5中，在当前目录新建文件夹/sda然后把/dev/sda5挂载进去

mkdir  ./sda

mount /dev/sda5 ./sda

5、进入sda文件夹中,拷贝state.tgz到tmp文件夹，然后解压进入etc目录找到密码文件

cp /sda/state.tgz  /tmp

tar  xvf state.tgz 得到local.tgz

tar xvf local.tgz得到etc文件夹

6、编辑shadow密码文件，把root列中的密码去掉，就是把第一个和第二个冒号之间的内容删除掉，然后保存退出。

7、重新压缩etc文件夹成local.tgz和state.tgz文件，放进sda文件夹中

tar czf local.tgz etc/

tar czf state.tgz local.tgz

cp state.tgz  /sda/

8、卸载/dev/sda5，完成重启即可。

sudo unmount  /dev/sda5

ESXI5的密码设置规则：https://communities.vmware.com/docs/DOC-31941

The password policy in ESXi 6 has following requirements:

• Passwords must contain characters from at least three character classes.
• Passwords containing characters from three character classes must be at least seven characters long.
• Passwords containing characters from all four character classes must be at least seven characters long.
• An uppercase character that begins a password does not count toward the number of character classes used.
• A number that ends a password does not count toward the number of character classes used.
• The password cannot contain a dictionary word or part of a dictionary word.
