登录MySQL
1 | mysql -u root -p |
添加新用户
允许本地 IP 访问 localhost, 127.0.0.1
1 | create user 'test'@'localhost' identified by '123456'; |
允许外网 IP 访问
1 | create user 'test'@'%' identified by '123456'; |
刷新授权
1 | flush privileges; |
为用户创建数据库
1 | 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
1 | 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
1 | grant all privileges on `testdb`.* to 'test'@'localhost' identified by '123456'; |
刷新权限
1 | flush privileges; |
退出 root 重新登录
1 | 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
1 | 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:
1 2 3 | # 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)
