MySQL Router的安装部署(2)-木庄网络博客

这个routerfriend账号的权限可能不够，我们也可以换成superdba的高权限账号去连接mysqlrouter，这样就可以对MySQL Server中的库表进行读写操作。

03 查看MySQL Router的元信息

MySQL Router搭建完毕后，可以通过查看元信息库mysql_innodb_cluster_metadata里面的表信息，包含cluster表、router表、以及instances表，对应的如下：

superdba@127.0.0.1 [mysql_innodb_cluster_metadata] 23:51:20>select * from instances;
+-------------+--------------------------------------+--------------------+--------------------------------------+--------------------+----------------------------------------+------------+-------------+

+-----------+-------------+--------------+-------------+---------+---------------------+------------------------------------------------------------------------------------------------------------------------------+--------------------------------------+---------+
1 row in set (0.00 sec)

还可以从表中查看当前的primary节点信息，primary_master字段为1的，即为primary节点。

superdba@127.0.0.1 [mysql_innodb_cluster_metadata] 23:52:29>select * from async_cluster_members;
+--------------------------------------+---------+-------------+--------------------+----------------+------------------------------------------------------------------------------------------------------------------+
