由于社区中MYSHELL SHELL版本是2.28，我特意安装了一台ORALCE LINUX 8虚拟机。
cat /etc/redhat-release
Red Hat Enterprise Linux release 8.9 (Ootpa）
ldd --version
ldd (GNU libc) 2.28

从上面的报错看，是python有问题。我安装的python3
在Greatsql社区发帖子咨询，叶金荣老师很快就回复了解决办法。作为开源社区，技术人员回复速度如此之快，确实少见。
解决方法如下：
# 先安装几个必要的依赖包
$ dnf install -y libssh python38 python38-libs python38-pyyaml
$ pip3.8 install --user certifi pyclamd
# 测试使用
$ /usr/local/greatsql-shell-8.0.32-25-centos-glibc2.28-x86_64/bin/mysqlsh
MySQL Shell 8.0.32

Type '\help' or '\?' for help; '\quit' to exit.

按照上面的方面处理，果然解决问题了。
