create subsscriptions - connection failure

[Rammurthy5]

Hello,
I have ubuntu 22.04 EC2 running, stuck at subscriptions creation.
I run the following command
./nodectl spock sub-create sub_n1n2 'host=<privateIP of node2> port=5432 user=root dbname=demo' demo

i used root for user in the above command because thats got superuser privileges in node2. i have tried changing to admin which DB username, then tried supplying --password with value still the same error. what am i doing wrong?

gets the error

ERROR: could not connect to the postgresql server: connection to server at "privateIP of node2", port 5432 failed: fe_sendauth: no password supplied
ERROR:

both the nodes are set without key-pair, same vpc, subnet.

As per the quick start, to use pgEdge platform you should use a non-root user with passwordless sudo privileges

Should I change an existing user to have root privileges and then try executing the command again? Do I understand it correctly ?

[cmotyka]

The user has to be not root and have passwordless sudo set up (https://www.ibm.com/docs/en/zscc/1.1.0?topic=eylzsdg-enable-passwordless-sudo-access-your-linux-user-id)
So everything from the command ./nodectl install pgedge -U superuser-name -P superuser-password -d database-name and on should be executed by a non-root user.

Superuser-name and superuser-password mentioned in the following command - does it mean the root or any user of the EC2 that has root privileges ?

./nodectl install pgedge -U superuser-name -P superuser-password -d database-name
