Linux环境MySQL Shell安装异常

安装mysql-shell-8.0.21-1.el7.x86_64.rpm时报异常:

error:unpacking of archive failed on file /usr/bin/mysqlsh:cpio:rename failed -Is a directory

error:mysql-shell-8.0.21-1.el7.x86_64.rpm install failed

原因：
安装mysql-shell-8.0.21-1.el7.x86_64.rpm时，需要操作mysqlsh文件的权限，把mysqlsh文件删除即可

解决方案：
rm -rf /usr/bin/mysqlsh
