创建用户报错ERROR 1364 (HY000): Field 'ssl_cipher' doesn't have a default value

今天第一次把玩mysql，在默认数据库mysql中创建用户时报错：

ERROR 1364 (HY000): Field 'ssl_cipher' doesn't have a default value

mysql> use mysql;

Reading table information for completion of table and column names

You can turn off this feature to get a quicker startup with -A

Database changed

mysql> SELECT host, user, password FROM user WHERE user = 'guest';

Empty set (0.23 sec)

mysql> INSERT INTO user 

    ->           (host, user, password, 

    ->            select_priv, insert_priv, update_priv) 

    ->            VALUES ('localhost', 'scofy', 

    ->            PASSWORD('mysql'), 'Y', 'Y', 'Y');

ERROR 1364 (HY000): Field 'ssl_cipher' doesn't have a default value

原因：在我的配置文件my.cnf中有这样一条语句

sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES

指定了严格模式，为了安全，严格模式禁止通过insert 这种形式直接修改mysql库中的user表进行添加新用户

解决办法：

将配置文件中的STRICT_TRANS_TABLES删掉，即改为：

sql_mode=NO_ENGINE_SUBSTITUTION

然后重启mysql即可
