1.数据库创建

第一步：登录数据库，输入命令sudo mysql -u root -p

[loongshawn@e100069197189.zmf /home/loongshawn]$sudo mysql -u root -p Enter password: ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: YES）[loongshawn@e100069197189.zmf /home/loongshawn]$sudo mysql -u root -p Enter password: Welcome to the MySQL monitor.  Commands end with ; or \g.Your MySQL connection id is 41892Server version: 5.6.21 MySQL Community Server (GPL)Copyright (c) 2000, 2010, Oracle and/or its affiliates.

第二步：登录数据库，查看当前已存在数据库，并创建创建数据库。

mysql> show databases;+--------------------+| Database|+--------------------+| information_schema || data_loong_1|| data_loong_2|| mapdata_1  || mapdata_2  || mysql  || performance_schema || rong_1 || rong_2 || test|+--------------------+10 rows in set (0.02 sec)

创建数据库命令create database knowledge_base_daily;

mysql> create database knowledge_base_daily;Query OK, 1 row affected (0.00 sec)

2.分配权限

给数据库分配用户、分配权限，由于库中已存在用户，就不再新建用户及权限了，然后manager这个用户拥有数据库的所有权限；

mysql> grant all privileges on knowledge_base_daily.* to 'manager'@'%' identified by '12345678';Query OK, 0 rows affected (0.08 sec)mysql> grant all privileges on knowledge_base_publish.* to 'manager'@'%' identified by '12345678';Query OK, 0 rows affected (0.00 sec)mysql> 

如果需要给具体用户分配数据库具体数据表的权限，使用以下命令，如manager拥有table的update权限。

grant update on knowledge_base_publish.table to 'manager'@'%';

补充说明如何新建用户，通过命令：

create user 'loongshawn'@'%' identified by '12345678';Query OK, 0 rows affected (0.08 sec)
