Exception encountered during startup: Unable to gossip with any seeds. I have 4 VMs. I make 1st VM's IP addrease as seed to the cluster. But when I installed cassandra on VM2 this message shows. Actually cassandra does not starts even not taking bin/cassandra command.

Make sure all Cassandra ports are reachable for inter VM communication. – Stefan Podkowinski

This is because I did not off firewall.

 $ service iptables status
 $ service iptables save
 $ service iptables stop

Or we have to enable following ports:

 $ iptables -I INPUT -p tcp -m tcp --dport 9042 -j ACCEPT
 $ iptables -I INPUT -p tcp -m tcp --dport 7000 -j ACCEPT
 $ iptables -I INPUT -p tcp -m tcp --dport 7001 -j ACCEPT
 $ iptables -I INPUT -p tcp -m tcp --dport 7199 -j ACCEPT

 $ /etc/init.d/iptables save
 $ service iptables restart
