Hi,
A few comments as I read:
> I'm using node0 as seeder
It is recommended to use at least 2 nodes per DC as seeds, for fault
tolerance and good gossip propagation.
Also I think you are a bit confused about what a seed node is and is not.
See:
I'm creating a cassandra cluster. I've three node with centos 7 and cassandra
3.4 installed.
Node0 interfaces:
eth0 169.254.169.xx1 (Public IP)
eth1 192.168.56.101(Private IP)
Node1 interfaces:
eth0 169.254.169.xx2 (Public IP)
eth1 192.168.56.102(Private IP)
Node2 interfaces:
