Mysql Innodb Cluster Replication
After spending a couple of days. Finally, find the solution. The solution is You have to whitelist IP of a primary and secondary node's in the /etc/hosts file in the primary Node. And Paste this below configuration in the /etc/mysql/my.cnf config file in all secondary node's. Please increment the server_id in all nodes.
etc/hosts file
# Your system has configured 'manage_etc_hosts' as True.
# As a result, if you wish for changes to this file to persist
# then you will need to either
# a.) make changes to the master file in /etc/cloud/templates/hosts.debian.tmpl
# b.) change or remove the value of 'manage_etc_hosts' in
#     /etc/cloud/cloud.cfg or cloud-config from user-data
