mysql資料庫使用者的建立_mysql建立使用者及資料庫

登陸mysql

[[email protected] conf]# mysql -uroot

建立使用者及密碼

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

建立資料庫

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

賦予新使用者操作新資料庫的權限

##本地通路

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

##遠端通路

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

##重新整理全局權限

mysql> flush privileges; 碰到問題：

不能直接使用insert語句進行新增使用者

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

建立使用者時隻能指向本機，否則本機登陸不了mysql

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

其它知識：

修改autocommit屬性值

[[email protected] ~]# vi /etc/my.cnf

##增加autocommit=0，不自動送出

autocommit=0

[[email protected] ~]# service mysql restart

另外一種建立方式：

[[email protected] dbgen]# mysql
