ERROR 1819 (HY000): Your password does not satisfy the current policy requirements
mysql> SET PASSWORD = PASSWORD("root");
ERROR 1819 (HY000): Your password does not satisfy the current policy requirements
所以你更改密码必须满足:数字、小写字母、大写字母 、特殊字符、长度至少8位
如此你便成功修改了密码,最后你还要设置一下过期时间,以防止密码失效。/etc/my.cnf
配置文件中增加
6.查看mysqld是否开机自启动,并设置为开机自启动:
1 chkconfig --list | grep mysqld 2 chkconfig mysqld on
7.修改字符集为UTF-8:
vim /etc/my.cnf
在[mysqld]部分添加:
character-set-server=utf8
在文件末尾新增[client]段,并在[client]段添加:
default-character-set=utf8
修改好之后重启mysqld服务:
service mysqld restart
查看修改结果:
mysql> show variables like "%character%"; +--------------------------+----------------------------+ | Variable_name | Value | +--------------------------+----------------------------+ | character_set_client | utf8 | | character_set_connection | utf8 | | character_set_database | utf8 | | character_set_filesystem | binary | | character_set_results | utf8 | | character_set_server | utf8 | | character_set_system | utf8 | | character_sets_dir | /usr/share/mysql/charsets/ | +--------------------------+----------------------------+ 8 rows in set (0.00 sec)
注:在修改密码步骤,若设置的密码为简单密码,可能会出现如下错误:
ERROR 1819 (HY000): Your password does not satisfy the current policy requirements
这一错误其实与validate_password_policy值的设置有关:
validate_password_policy值默认为1,即MEDIUM,所以刚开始设置的密码必须符合长度要求,且必须含有数字,小写或大写字母,特殊字符
如果我们只是做为测试用而不需要如此复杂的密码,可使用如下方式修改validate_password_policy值
mysql> set global validate_password_policy=0; Query OK, 0 rows affected (0.00 sec)
这样,对密码要求就只有长度了,而密码的最小长度由validate_password_length值决定
validate_password_length参数默认为8,它有最小值的限制,最小值为:
validate_password_number_count+ validate_password_special_char_count+ (2 * validate_password_mixed_case_count)
其中,validate_password_number_count指定了密码中数字的长度,validate_password_special_char_count指定了密码中特殊字符的长度,validate_password_mixed_case_count指定了密码中大小字母的长度。这些参数的默认值均为1,所以validate_password_length最小值为4,如果显性指定validate_password_length的值小于4,尽管不会报错,但validate_password_length的值将设为4
设置validate_password_length的值:
mysql> set global validate_password_length=4; Query OK, 0 rows affected (0.00 sec)
如果修改了validate_password_number_count,validate_password_special_char_count,validate_password_mixed_case_count中任何一个值,则validate_password_length将进行动态修改。
