I want to ask next, public IP and private IP, virtual IP, scan - what IP IP correspond my environment?

CodePudding user response:

Public IP is your host foreign IP, VIP during the installation process is bound to the public IP network card IP, you don't need to worry about, private IP is used to cluster of internal communication, independent of the public IP network card, SCAN IP like VIP, usually without the assistance from external service, use the/etc/hosts, will only start to start on the node in the cluster, this is also the installation process will create IP, don't need to add
