Mysql密码安全策略

Server version: 5.7.9-log MySQLCommunity Server (GPL)

 

mysql> GRANT REPLICATION CLIENT ON *.*TO 'zabbix'@'%' IDENTIFIED BY ‘xxxxxxxx’;

ERROR 1819 (HY000): Your password does notsatisfy the current policy requirements

 

这个与validate_password_policy的值有关。

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

 

默认是1  ：符合长度，且必须含有数字，小写或大写字母，特殊字符。

如果是测试环境不想密码很复杂，可以修改：

 

set global validate_password_policy=0;

 

mysql> GRANT REPLICATION CLIENT ON *.* TO 'zabbix'@'%' IDENTIFIED BY 'xxxxxxxx';

Query OK, 0 rows affected, 1 warning (0.02sec)

 

 

更改密码长度：密码最小长度为4
mysql> set global validate_password_length=0；
Query OK, 0 rows affected (0.00 sec)

mysql> SHOW VARIABLES LIKE 'validate_password%';
