mysql error You must reset your password using ALTER USER statement before executing this statement.
mysql修改密码Your password does not satisfy the current policy requirements
出现这个问题的原因是:密码过于简单。刚安装的mysql的密码默认强度是最高的,如果想要设置简单的密码就要修改validate_password_policy的值,
validate_password_policy有以下取值:
| Policy | Tests Performed |
|---|---|
0 or LOW |
Length |
1 or MEDIUM |
Length; numeric, lowercase/uppercase, and special characters |
2 or STRONG |
Length; numeric, lowercase/uppercase, and special characters; dictionary file |
如果要修改这个值,
1、先登入到mysql

2、设置安全级别

3、默认密码长度为8,可以设置为其它值,最小4位

4、设置新密码,刚安装完的mysql必须设置新密码(应该是从5.5版本开始)

安装完mysql 之后,登陆以后,不管运行任何命令,总是提示这个
step 1: SET PASSWORD = PASSWORD('your new password');
step 2: ALTER USER 'root'@'localhost' PASSWORD EXPIRE NEVER;
step 3: flush privileges;
完成以上三步退出再登,使用新设置的密码就行了,以上除了红色的自己修改成新密码外,其他原样输入即可
