mysql8有个重要的特性，大小写敏感只能在数据库初始化的时候完成，所以我们要在args加入–lower_case_table_names=1，即大小写不敏感

创建用户，mysql8需要先创建用户才能分配权限

use mysql;create user 'szxy_test'@'%' identified by 'Liweilun1208.';

如果创建用户时忘记with mysql_native_password
用该用户登录会报authentication plugin 'caching_sha2_password' cannot be loaded;

alter user 'szxy_test'@'%' identified with mysql_native_password by 'Liweilun1208.';

分配权限

grant all privileges on *.* to 'szxy_test'@'%' with grant option;
