1.登录root账户,

apuser@bjzktmp02u:~$ mysql -u root -p 
Enter password: 
Welcome to the MySQL monitor.  Commands end with ; or \g.
Your MySQL connection id is 70
Server version: 5.5.54-0ubuntu0.12.04.1 (Ubuntu)

Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.

mysql> 

2.添加新用户one

mysql> create user 'one'@'localhost'identified by '789';
Query OK, 0 rows affected (0.00 sec)

mysql> 

3.允许外网IP访问

mysql> create user 'one'@'%'identified by '789'; 
Query OK, 0 rows affected (0.00 sec)

mysql> 

4.刷新权限

mysql> flush privileges;
Query OK, 0 rows affected (0.02 sec)

mysql> 

5.为用户创建数据库

mysql> create database one DEFAULT CHARSET utf8 COLLATE utf8_general_ci;
Query OK, 1 row affected (0.03 sec)

mysql> 

6.为新用户分配权限

授予用户通过外网IP对于该数据库的全部权限

mysql> grant all privileges on `onedb`.* to 'one'@'%' identified by '789'; 
Query OK, 0 rows affected (0.00 sec)

mysql> 

7.刷新权限

mysql> flush privileges;
Query OK, 0 rows affected (0.00 sec)

mysql> 

8.现在可以退出root,登录自己的one

mysql> exit
Bye
apuser@bjzktmp02u:~$ mysql -u one -p
