初始化CM遇到N多问题，请大仙指导

//初始化CM，执行下面脚本
/opt/cm-5.13.3/share/cmf/schema/scm_prepare_database.sh mysql -hlocalhost -uroot -proot --scm-host localhost scm scm scmpassword
错误1：
Your password does not satisfy the current policy requirements

mysql 的 validate_password_policy  已经设置为 LOW ，已经重启服务，求解。谢谢

validate_password插件是mysql5.6以后可以引入的一个新密码校验插件,判断修改密码时候新密码是否符合当前的策略，不满足报错，不让修改。

更多内容如下：
validate_password_policy作用

判断修改密码时候新密码是否符合当前的策略，不满足报错，不让修改。

validate_password_policy类型[td]

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

用于控制validate_password行为系统参数：

　　这些参数是要安装好validate_password 插件后才能通过show variables like 'validate_password%';看到。

　　001、validate_password_policy 这个参数用于控制validate_password的验证策略 0-->low  1-->MEDIUM  2-->strong。

　　002、validate_password_length密码长度的最小值(这个值最小要是4)。

　　003、validate_password_number_count 密码中数字的最小个数。

　　004、validate_password_mixed_case_count大小写的最小个数。

　　005、validate_password_special_char_count 特殊字符的最小个数。

　　006、validate_password_dictionary_file 字典文件

查看所有的validate_password相关的参数值

mysql> SHOW VARIABLES LIKE 'validate_password%';
+--------------------------------------+--------+
| Variable_name                        | Value  |
+--------------------------------------+--------+
| validate_password_check_user_name    | OFF    |
| 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      |

设置的口令是 Scm1@#scm，应该符合要求了。

再次运行同样的语句，报错
