MySQL添加新用户、创建数据库、分配权限

登录MySQL

mysql -u root -p

查看当前用户

select user,host from mysql.user;

添加新用户

允许本地 IP 访问 localhost, 127.0.0.1

create user 'test'@'localhost' 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;

退出 root 重新登录
exit
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

不然会报如下错误:

ERROR 2003 (HY000): Can't connect to MySQL server on 'host' (111)
