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:

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)
