我正在尝试通过ssh隧道进行mariadb复制。 这是我的configuration。 首先，我创build了一个从我的复制服务器（R1）到我的主服务器（M1）的ssh隧道。
ssh -L 13306:localhost:3306 -p 22111 admin@M1 -f -N 两个mariadb实例已经在两台服务器上运行。 而且我已经在M1 mariadb实例上创build了一个复制用户。
CREATE USER 'replication'@'127.0.0.1' identified by 'xxxx'; GRANT REPLICATION SLAVE on *.* to 'replication'@'127.0.0.1' REQUIRE SSL;
从R1我检查我是否可以连接到M1 mariadb实例。
mysql -u replication -pxxxx -h 127.0.0.1 --protocol=TCP -P 13306
以上操作成功。 但是现在，当我指示复制实例R1 更改主机并启动从机时 ，它将失败。

指向错误configuration的任何帮助是非常受欢迎的。
