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

可以看到如上报错：Your password does not satisfy the current policy
requirements密码不符合要求
我们先看密码策略

 mysql>  SHOW VARIABLES LIKE 'validate_password%'; 
+--------------------------------------+--------+
| Variable_name                        | Value  |
+--------------------------------------+--------+
| validate_password.check_user_name    | ON     |
| validate_password.dictionary_file    |        |
| validate_password.length             | 8      |
| validate_password.mixed_case_count   | 1      |
| validate_password.number_count       | 1      |
| validate_password.policy             | MEDIUM |
| validate_password.special_char_count | 1      |
+--------------------------------------+--------+
7 rows in set (0.01 sec)

策略说明
validate_password.length 是密码的最小长度，默认是8，我们把它改成6
输入：set global validate_password.length=6;
validate_password.policy 验证密码的复杂程度，我们把它改成0
输入：set global validate_password.policy=0;
validate_password.check_user_name 用户名检查，用户名和密码不能相同，我们也把它关掉
输入：set global validate_password.check_user_name=off;

mysql> set global validate_password.length=6;
Query OK, 0 rows affected (0.00 sec)

mysql> set global validate_password.policy=0;
Query OK, 0 rows affected (0.00 sec)

mysql> set global validate_password.check_user_name=off;
Query OK, 0 rows affected (0.00 sec)

mysql> create user zabbix@localhost identified by 'Linux112';
Query OK, 0 rows affected (0.01 sec)

这样就能修改成功啦！！
