登陸mysql

[root@dn210120 conf]# mysql -uroot

創(chuàng)建用戶及密碼

mysql> grant usage on *.* to 'hive14'@'localhost' identified by '123456' with grant option;

創(chuàng)建數(shù)據(jù)庫

mysql> create database hive14 DEFAULT CHARACTER SET utf8 COLLATE utf8_general_ci;

賦予新用戶操作新數(shù)據(jù)庫的權(quán)限

##本地訪問

mysql> grant all privileges on hive14.* to hive14 identified by '123456';

##遠(yuǎn)程訪問

mysql> grant all privileges on hive14.* to hive14@'%' identified by '123456';

##刷新全局權(quán)限

mysql> flush privileges; 碰到問題：

不能直接使用insert語句進(jìn)行新增用戶

mysql> insert into mysql.user(Host,User,Password) values("localhost","hive14",password("1234"));

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

創(chuàng)建用戶時(shí)只能指向本機(jī)，否則本機(jī)登陸不了mysql

grant usage on *.* to 'hive14'@'%' identified by '123456' with grant option;

其它知識：

修改autocommit屬性值

[root@dn210120 ~]# vi /etc/my.cnf

##增加autocommit=0，不自動提交

autocommit=0

[root@dn210120 ~]# service mysql restart

另外一種創(chuàng)建方式：

[root@dn210120 dbgen]# mysql
