如何使用 MariaDB Maxscale 配置只读服务器

Question

Is it possible to configure a read-only server that remains slave even though no more masters are available with MariaDB Maxscale 6. I tried it with a readconroute router, but that one turned the slave eventually in to a master as well.

Answer 1

If you are using the mariadbmon monitor, you can use the servers_no_promotion parameter to list the server you want to remain read-only.

For galeramon there should be no need to keep servers as read-only as all functioning nodes are capable of receiving writes.
