mysql用户管理

登录MySQL

 

mysql -u root -p

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';

grant all privileges on  *.* to 'root'@'%' identified by '123456';//容许远程连接

 

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:

 

  1.  
    # Instead of skip-networking the default is now to listen only on
  2.  
    # localhost which is more compatible and is not less secure.
  3.  
    #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)

 

注意:

centos6.9 安装mysql5.5不能远程连接问题

 

service iptables stop
