Hi Peer,

https://gist.githubusercontent.com/cdwijayarathna/a14586a9e39a943f89a0/raw/system%20log This is the log of the last time I started the server, I couldn't found any error there.

Thanks

Try looking in the log file (/var/log/cassandra/system.log) for errors that prevent your node from starting.

Are you sure your node is up? Do you get a result when running “nodetool –h 192.248.15.219 status”?

You also have to change the same IP which is 192.248.15.219 for seeds inside cassandra.yaml file.

 

then try to connect, it will work.

 

Thanks,

Hello all,

 

After starting cassandra, I tried to connect to cassandra from cqlsh and java, but it fails to do so.

 

Following is the error I get while trying to connect to cqlsh.

 

cqlsh -u sinmin -p xxxxxx

Connection error: ('Unable to connect to any servers', {'127.0.0.1': error(111, "Tried connecting to [('127.0.0.1', 9042)]. Last error: Connection refused")})

 

I have set listen_address and rpc_address in cassandra.yaml to the ip address of server address like follows.

 

listen_address:192.248.15.219

rpc_address:192.248.15.219

 

Following is what I found from cassandra system.log.

 

Following is the netstat result I got.
