一次linux服务器系统挂掉修复过程

[xiaowhy]

1.linux突然提示连接不上，bash相关的命令都找不到，重启后提示 /bin/sh:ro: No such file or directory
2.制作U盘操作系统，启动U盘操作系统后挂载linux硬盘，查看log发现 系统yum erase 了大量rpm包，导致系统相关的命令都缺失
3.尝试从另外台服务器上将系统关键目录下文件拷贝过来，但发现在U盘操作系统里不能打包或解压，拷贝文件夹，又导致很多链接失效
4.刻录系统盘，从光盘启动，进入修复模式，因为rpm包等命令都没有，将修复模式下的rpm命令拷贝到损坏的linux系统目录下
5.使用光盘升级修复功能，修复linux
6.修复完成后可以正常启动，但缺失很多包
7.将yum源配置为光盘，用rpm命令安装yum包后，再使用yum安装基础的包
8.重启后正常，还好数据库的数据都还在。

have u figured out why that happened? Who executed "yum erase"? Was it an accident or hacked by someone?

lz这是治标不治本，确实该查找谁执行的yum erase
