  • Make a backup copy before modifying any file.

Conventions used in this lab

Shells and Prompts

Bastion
ec2-user  ~ 
Example command with sample output.
cat /etc/redhat-release
Red Hat Enterprise Linux release 8.1 (Ootpa)

Getting access to the servers

Use the web console to login to the bastion:

https://bastion-0.example.redhatgov.io:9090/system/terminal

Use ssh to login to the nodes, from the bastion:

ssh node1-0.example.redhatgov.io
ssh node2-0.example.redhatgov.io

For each node, you will be asked to confirm that the key fingerprint is OK, as you haven’t logged into it, before.

Node 1:

The authenticity of host 'node1-0.example.redhatgov.io (10.0.2.128)' can't be established.
ECDSA key fingerprint is SHA256:X6KOWD5YgDqcGxnSKDgT0ZYWqBeG8yw9CKTvgFwT6sQ.
Are you sure you want to continue connecting (yes/no/[fingerprint])?

Respond with yes or y to accept the key:

yes

Logout when done.

Node 2:

The authenticity of host 'node2-0.example.redhatgov.io (10.0.2.125)' can't be established.
ECDSA key fingerprint is SHA256:n2/LxFOXS2of8osIEcY/5911N6OmqaJJpsYRgnVrsiA.
Are you sure you want to continue connecting (yes/no/[fingerprint])?

Again, respond with yes or y to accept the key:

yes

Logout when done.

Now, let’s move on to lab #2!
