我一直试图让MySQL复制设置在数字海洋与伪造服务器和玛丽亚DB。
运行从属状态时,我一直收到此错误\g:
致命错误:slave I/O线程停止,因为master和slave具有相同的MySQL服务器ID;这些id必须不同,复制才能工作(或者必须在slave上使用--replicate-same-server-id选项,但这并不总是有意义的;请在使用前检查手册)。
这是我遵循的教程:https://www.digitalocean.com/community/tutorials/how-to-set-up-master-slave-replication-in-mysql
我已经检查了我的.conf文件中的server-id,主服务器设置为1,从服务器设置为2。
下面是完整状态输出的转储
MariaDB [(none)]〉显示从机状态\G

有人能帮忙吗?

检查配置文件是否被使用。它可能是/etc/my.cnf(不是my.conf)。
在两台服务器上运行SHOW VARIABLES LIKE 'server_id';
检查server_id是否在my.cnf[mysqld]部分。

在我的例子中,我已经确定不同的节点配置了不同的servers_id

SHOW VARIABLES LIKE 'server_id';

然后,重新配置复制...

stop slave;
reset slave;
change master to ...
start slave;
