升级基础库风险较大，牵扯到一系列上层库、应用
clang问题已解决，其他的暂时不管了。
`GLIBCXX_3.4.26' not found
gcc与libstdc++版本关系：
https://www.cnblogs.com/freelancy/p/17012054.html
https://gcc.gnu.org/onlinedocs/libstdc++/manual/abi.html
得到对照关系
| GCC 9.1.0 | GLIBCXX_3.4.26 | CXXABI_1.3.12 | libstdc++.so.6.0.26 |
获取源码，编译libstdc++ 3.4.26

kex_exchange_identification: read: Connection reset by peer
Connection reset
由于升级的glibc导致ssh故障，放弃openEuler 20.03 LTS SP3 此方案。
灾后自救
当前状态：
ssh无法登录
SOL控制台或者虚拟虚拟化均表现为，输入用户名，回车不会提示输入密码，无法登录。
只能在之前已经打开ssh的终端上面执行：
