Centos7-mysql运行报错ERROR 1820 (HY000): You must reset your password using A...

定位

刚安装的mysql，输入任何内容都报

ERROR 1820 (HY000): You must reset your password using ALTER USER statement before executing this statement.

就是要重新设置一下密码的意思

SET PASSWORD = PASSWORD('yourpwd');

继续报错：ERROR 1819 (HY000): Your password does not satisfy the current policy requirements
密码太简单了。？？？ 还简单？ 干脆修改密码策略。

set global validate_password_policy=0;
set global validate_password_length=1;

SET PASSWORD = PASSWORD('yourpwd');

ok!
