添加新用户

允许本地 IP 访问 localhost, 127.0.0.1

create user 'test'@'localhost' identified by '123456';

允许外网 IP 访问

create user 'test'@'%' identified by '123456';

刷新授权

flush privileges;

为用户创建数据库

create database test DEFAULT CHARSET utf8 COLLATE utf8_general_ci; 

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

    
grant all privileges on `testdb`.* to 'test'@'%' identified by '123456'; 

授予用户在本地服务器对该数据库的全部权限

grant all privileges on `testdb`.* to 'test'@'localhost' identified by '123456';

刷新权限

flush privileges;

用新帐号 test 重新登录,由于使用的是 % 任意IP连接,所以需要指定外部访问IP

mysql -u test -h 115.28.203.224 -p 

在Ubuntu服务器下,MySQL默认是只允许本地登录,因此需要修改配置文件将地址绑定给注释掉:

# Instead of skip-networking the default is now to listen only on 
# localhost which is more compatible and is not less secure. 
#bind-address       = 127.0.0.1     #注释掉这一行就可以远程登录了
