回答1:
sounds like you didn't edit rpc_address in cassandra.yaml to listen on the public interface instead of localhost.
回答2:
- Goto EC2 Management Console
- Click on Security Groups under Network and Security on the left menu
- Select your Security Group associated with your instance and click on Inbound Tab
- Find out what is the source for ALL Port (Service). If the source is sg-xxxxxxxx, then delete the same.
- Add a new rule by selecting the below options: Create a new rule: All Traffic Source: 0.0.0.0/0
- Add Rule and click on Apply Rule changes
- To verify if you are able to connect to Cassandra server, run the cassandra client from your local machine like below:
cassandra-cli -host ec2-XX-XXX-XX-XXX.us-west-2.compute.amazonaws.com -port 9160
