dba.configureInstance:This function is not available through a session to an instance

报错信息dba.configureInstance:This function is not available through a session to an instance belonging to an unmanaged asynchronous replication topology

输入命令后dba.configureInstance('root@localhost:3306');报错（用127.0.0.1也一样）：

Dba.configureInstance: This function is not available through a session to an instance belonging to an unmanaged asynchronous replication topology (RuntimeError)

换成如下命令即可：

dba.configureInstance('root@192.168.31.101:3306');
