MySQL复制多主服务器，具有动态IP到单个从服务器

Question

So I have a collection of data gathering devices that run MySQL and OpenVPN. The OpenVPN runs in either TCP or UDP, but not both and uses different subnets for each and the mode can switch based on availability. In MySQL 5.7, multi-master replication requires a static IP address. This is not a problem if the IP addresses didn't change on the devices, but they do.

How can I make MySQL multi-master replication work with an indeterminate master address?

Answer 1

You can assign static IP addresses based on certificate CN's: http://michlstechblog.info/blog/openvpn-set-a-static-ip-address-for-a-client/

I believe that it also should work on user/password authentication...
