SSH in production environment
Hi ,
Can somebody please clarify in real production environment with multiple
nodes in cluster does ssh is implemented with or without it. I have seen
examples where keys are generated and those keys are copied in authorized
files in other nodes to login to other nodes.
Is this the same way done in real production environment.
Please help
Regards
Shashidhar

If you want to use start-all.sh, you need to configure ssh keys or you can
login the target machine to start service
