hello:
Is it possible to config the node with public ip address, I have three node, for some reason, they cant reach each other in the internal network but public ip, Each node has only the local network interface with private ip.If its possible,how to config it.
thx a lot!
Hello @xiaolllll, yes, set wsrep_cluster_address and wsrep_node_address to the public IP. If you are having issues with internal IPs, check all proper port (3306, 4444, 4567, 4568) are open between all nodes.

My host has only local private address, the public ip is on the network devices.
Any other info needed pls tell me.
Then it is not possible to bind the node to use the public IP. You must use the actual IP of the network interface on the server.
