解决ERROR 1819 (HY000): Your password does not satisfy the current policy requirements

@[TOC](解决ERROR 1819 (HY000): Your password does not satisfy the current policy requirements) 今天安装mysql修改密码时会遇到

ERROR 1819 (HY000): Your password does not satisfy the current policy requirements

原因：

自定义密码太简单，不符合密码策略

查看 mysql 初始密码策略

mysql> SHOW VARIABLES LIKE 'validate_password%'; 

如果遇到

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

修改策略，密码长度

mysql> set global validate_password.policy=0 mysql> set global validate_password.length=1; 

validate_password.policy取值

0 or LOW 只验证长度 1 or MEDIUM 验证长度、数字、大小写、特殊字符 2 or STRONG 验证长度、数字、大小写、特殊字符、字典文件 再次修改密码语句

mysql> ALTER USER 'root'@'localhost' IDENTIFIED BY '123456';
