## 场景 ##

在 ubuntu 上使用 Docker 安装了 Mysql 8 ，远程连接一直报错

Communications link failure
    
    The last packet sent successfully to the server was 0 milliseconds ago. The driver has not received any packets from the server.
      Can not read response from server. Expected to read 4 bytes, read 0 bytes before connection was unexpectedly lost.
      Can not read response from server. Expected to read 4 bytes, read 0 bytes before connection was unexpectedly lost.

先设置 远程登录权限，在进入 docker 容器后，使用命令行客户端连接MySQL ,执行如下语句：

GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY '123456' WITH GRANT OPTION;
    -- 或者
    GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY '123456';

都报如下错误：

ERROR 1064 (42000): You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'INDENTIFIED WITH mysql_native_password BY '123456'' at line 1

## 解决方案 ##

根据提示，应是MYSQL 版本不同，语法不同所致。MySQL 8.0.x 应使用如下语句。

GRANT ALL PRIVILEGES ON *.* TO 'root'@'%';
