redhat 7.7 rpm -qa|xargs rpm -e --nodeps 修复全记录
1. 准备一个可用的linux系统（测试的话记得快照哦~）
2.骚操作开始：
rpm -qa|xargs rpm -e --nodeps
3.重启看报错 :/#
4.系统提示：你降生到了一片漆黑的地方！。。。。什么！新手送了把屠龙刀？扔了！
ls
emm 好像物资挺丰富，我决定删掉 /bin 和 /sbin
5.干净了。。。
6.拯救开始！挂个光盘先~（此步略，U盘虚拟机cdrom，你们爱怎么挂怎么挂，不懂自己百度去）
7.进入grub模式，此界面按 'c'
8.看看哪个盘可以用
好像都不是，那我放弃！
9.真是 山重水复疑无路，柳暗花明又一村 ~ 居然进入光盘引导了
选择Troubleshooting → Rescue a CentOS system
选择1 回车
9. 成功进入光盘系统！送你一堆王之宝具！
10.执行以下指令：
sh-4.2# mkdir /mnt/cdrom //千万不要挂载到 /mnt 下 你还挂着个系统呢！
sh-4.2# blkid //查看U盘或cd是哪个
sh-4.2# mount /dev/sr0 /mnt/cdrom //挂载cd，我的cd是/dev/sda1
sh-4.2# rpm -ivh /mnt/cdrom/Packages/包名 --nodeps --root /mnt/sysimage --force //一定要指定root,因为你目前的根目录是cd的
包名如下：
