通过数据库名称溃败mysql查询到不同的服务器

Question

我们有一台服务器的数据库太多。我们一直在不断增长，并添加了更多的数据库。

我们希望能够添加更多的mysql服务器，并让我们的客户端透明地访问代理（sqlproxy？），并使其通过数据库名称将查询定向到正确的服务器。

可以将sqlproxy配置为执行此操作吗？我只看到通过查询重定向。

有什么解决办法吗？

I can understand the -1s above: a simple google throws up many articles that explain how to do this, but I'll answer the question regardless of this.

Yes it's possible: you basically can do it with maxscale and proxysql. Proxysql is easier to implement and offers query routing out of the box. You basically create for each of the sharded/partitioned hosts a hostgroup. Then you create a rule matching the schema you wish to redirect and insert the designated hostgroup here.

This tutorial will explain everything you need to know and is easy to follow:
