Connect remote scylla db server shows error - cassandra

Question

I have installed scylla-db in google cloud servers.
Steps i have followed:
sudo yum install epel-release
sudo curl -o /etc/yum.repos.d/scylla.repo -L http://repositories.scylladb.com/scylla/repo/a2a0ba89d456770dfdc1cd70325e3291/centos/scylladb-2.0.repo
sudo yum install scylla
sudo scylla_setup
(Given yes to "verify supportable version" , " verify packages" , "core dump", " fstim ssd "
For remaining : Given NO)
IN file :/etc/scylla.d/io.conf
SEASTAR_IO="--max-io-requests=12 --num-io-queues=1"
( edited this file manually )
sudo systemctl start scylla-server
It shows: Cannot able to read yaml file. Then google it and downgraded the yaml-cpp version to 0.5.1 from 0.5.3 version.
then
scylla-server started running .

scylla-server is running.
Same setup was done another server
Server Name scylla-db-1
I need to connect to the server scylla ( IP: xx.xx.xxx) from this server.
when i execute the below :
[root#scylla-db-1 ~]# cqlsh xx.xx.xxx
Connection error: ('Unable to connect to any servers', {'xx.xx.xxx': error(111, "Tried connecting to [('xx.xx.xxx', 9042)]. Last error: Connection refused")})
How to connect the remote server from this server?
Also
while checking the http://xx.xx.xxx:10000 and http://xx.xx.xxx:10000/ui in the browser , I m getting problem loading page.
Note :
I have done editing the /etc/scylla.d/io.conf file for assigning the
max-io-requests manually

Answer 1

Port 10000 is the rest api for scylla and is usually left bounded to the 127.0.0.1 - thats why you can not access it
To gain access via cql you need to edit the /etc/scylla/scylla.yaml file and set the rpc_address
Please follow the instructions for configuring scylla for a cluster deployment: single dc http://docs.scylladb.com/procedures/create_cluster/ or multi dc http://docs.scylladb.com/procedures/create_cluster_multidc/.

Answer 2

You need set rpc_address on scylla.yaml and while connecting through cql give your rpc_address as well cqlsh xx.xxx.xxx.xx with user/pass if enabled.
