解决方案：

卸载现有环境，或者备份数据库

重新初始化用以下命令执行：[bes@test162 bin]$ ./mysqld --initialize --user=bes --basedir=/home/bes/mysql-8.0.11/ --datadir=/home/bes/mysql-8.0.11/data  --lower_case_table_names=12022-09-02T10:33:01.134249Z 0 [Warning] [MY-011070] [Server] 'Disabling symbolic links using --skip-symbolic-links (or equivalent) is the default.
