Failed to add a new machine as a leaf node to the existing memsql cluster

Help

Hi ,

Have a Memsql cluster with two leaf nodes, one aggregator and one master. Launched this cluster using CloudFormation stack provided in aws market place ( AWS Marketplace: MemSQL).

Now, I’m planning to add one more EC2 to the existing cluster as a leaf node. Launched new EC2 machine with Linux OS and doesn’t have memsql configuration and attached same security group, subnet, vpc and key pair.

When I tried to register this host , I’m getting ssh connection issue.

 memsql-toolbox-config register-host --host 18.***.153.*** --identity-file *****.pem
Toolbox is about to register the following host:
  · Host: 18.***.153.***
  · Localhost: false
  · Identity File: /home/ec2-user/***.pem

Would you like to continue? [y/N]: y
Error connecting to host.
Please use --ssh if this is a remote host or --localhost if this is the local host.
SSH error output is below:

SSH Master process failed to initialize in time: context deadline exceeded

Keypair whatever I’m using as passphrase too. Is it causing the issue?

I tried this configuration from below reference links:

Thanks
Arun

The error you received (which is badly written, we will address that) means that we timed out while trying to connect to the node. Ensure that you can SSH to the host from the host on which you are running register-host. The default SSH port is 22 so make sure that is open on the new host’s firewall. And the default user used when ssh’ing is whatever user you run the register-host command as, so make sure you are using that user.
