登陆mysql

[root@dn210120 conf]# mysql -uroot

创建用户及密码

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

创建数据库

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

赋予新用户操作新数据库的权限

##本地访问

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

##远程访问

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

##刷新全局权限

mysql> flush privileges; 碰到问题：

不能直接使用insert语句进行新增用户

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

创建用户时只能指向本机，否则本机登陆不了mysql

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

其它知识：

修改autocommit属性值

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

##增加autocommit=0，不自动提交

autocommit=0

[root@dn210120 ~]# service mysql restart

另外一种创建方式：

[root@dn210120 dbgen]# mysql
