Question

我在两个不同的主机上有两个MariaDB 10.1.16服务器。我设置了Master-Slave副本，没有错误：

+-----------------------+----------+--------------+------------------+

警报日志中没有错误或警告。

掌握my.cnf：

[mysqld]
server_id=1
relay-log=host02-relay-bin
log-bin=host02-bin

奴隶my.cnf：

[mysqld]
log-bin
server_id=2
replicate-do-db="db1,db2,db3,db4,db5"
relay-log=host03-relay-bin
log-bin=host03-bin

问题是没有错误，但MASTER（例如INSERT）中的更改不会在SLAVE上复制。可能是Replicate_Do_DB问题？

Answer 1

您可能没有名为db1,db2,db3,db4,db5的数据库。

相反，在奴隶的my.cnf中有5 replicate-do-db行。

另外，请务必不要这样做：

USE db88;
INSERT INTO db1.tbl ...

将使用db88代替db1，并且将忽略插入。

MariaDB主从复制不会没有错误
