## MariaDB新安装后，需要强制创建一个用户用于远程访问（非本机IP访问），本机IP访问仅限root用户
|
||||
|
||||
进入 MariaDB（使用 socket 登陆）：
|
||||
```
|
||||
sudo mysql -u root -p -S /run/mysqld/mysqld10.sock
|
||||
|
||||
```
|
||||
|
||||
查看 root 主机权限：
|
||||
``` sql
|
||||
select host, user from mysql.user;
|
||||
```
|
||||
|
||||
``` bash
|
||||
shenwei@SHENWEI_DS718:/usr/local/mariadb10/etc/mysql$ sudo mysql -u root -p -S /run/mysqld/mysqld10.sock
|
||||

|
||||
|
||||
这里已经看到关键问题了：
|
||||
**你的 MariaDB 只有 `root@localhost`，并没有 `root@%` 或你要连接用的用户账号**。
|
||||
而从你外部客户端连接失败的最常见原因就是：**没有对应的 Host/User 组合 + 缺少权限**。
|
||||
|
||||
你现在的 `mysql.user` 内容：
|
||||
|
||||
``` bash
|
||||
| | PUBLIC |
|
||||
| localhost | mariadb.sys |
|
||||
| localhost | mysql |
|
||||
| localhost | root |
|
||||
|
||||
```
|
||||
|
||||
|
||||
这里唯一能用的账号就是：
|
||||
|
||||
- `root@localhost` → **只能从本机 localhost 登录**
|
||||
这意味着从 **Synology Docker、其他机器、同网段的客户端** 都不能用 root 连接。
|
||||
|
||||
## 创建一个允许远程访问的用户
|
||||
|
||||
``` sql
|
||||
CREATE USER 'shenwei'@'%' IDENTIFIED BY '!Abcde12345';
|
||||
GRANT ALL PRIVILEGES ON *.* TO 'shenwei'@'%' WITH GRANT OPTION;
|
||||
FLUSH PRIVILEGES;
