Establish SSH Connectivity

After Ansible was successfully installed, SSH equivalency was established and Ansible was tested.

Establish SSH Credentials on AUBURN

The following command was used to establish SSH credentials on AUBURN :

ssh-keygen

The output was:

Generating public/private rsa key pair.
Enter file in which to save the key (/home/douglas/.ssh/id_rsa):
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /home/douglas/.ssh/id_rsa.
Your public key has been saved in /home/douglas/.ssh/id_rsa.pub.
The key fingerprint is:
SHA256:shjEH2qkzF+G4j+eNxAlULEyDUikdRuVVNH+HU10AmA douglas@auburn.yaocm.id.au
The key's randomart image is:
+---[RSA 2048]----+
|o++o=+ooooE.....o|
|o. =.+o  ..    .o|

+----[SHA256]-----+

Propagate SSH Credentials to PENRITH

The following command was used to copy SSH credentials on AUBURN to PENRITH :

ssh-copy-id penrith.yaocm.id.au

The output was:

/usr/bin/ssh-copy-id: INFO: Source of key(s) to be installed: "/home/douglas/.ssh/id_rsa.pub"
The authenticity of host 'penrith.yaocm.id.au (192.168.1.249)' can't be established.
ECDSA key fingerprint is SHA256:bjjW/BAGqhn1meKlFTMV2JKsDLfHv3Mm6YbKGVmhfsI.
Are you sure you want to continue connecting (yes/no)? yes
/usr/bin/ssh-copy-id: INFO: attempting to log in with the new key(s), to filter out any that are already installed
/usr/bin/ssh-copy-id: INFO: 1 key(s) remain to be installed -- if you are prompted now it is to install the new keys
douglas@penrith.yaocm.id.au's password:

Number of key(s) added: 1

Now try logging into the machine, with:   "ssh 'penrith.yaocm.id.au'"
and check to make sure that only the key(s) you wanted were added.

Propagate SSH Credentials to PENRITH

The following command was used to copy SSH credentials from AUBURN to PENRITH :

ssh penrith.yaocm.id.au

The output was:

Testing

Followed the procedure in Your first commands .

Establish Hosts Inventory

On AUBURN , the file /etc/ansible/hosts was set to contain the following:

# Client machines

[clients]
penrith.yaocm.id.au

# Oracle RAC Nodes

[oracle_rac]
redfern1.yaocm.id.au
redfern2.yaocm.id.au

Do PING Test

To test Ansible connectivity to the hosts, the following command was used:

ansible all -m ping

The output was:

redfern1.yaocm.id.au | SUCCESS => {
    "changed": false, 
    "ping": "pong"
}
penrith.yaocm.id.au | SUCCESS => {
    "changed": false, 
    "ping": "pong"
}
redfern2.yaocm.id.au | UNREACHABLE! => {
    "changed": false, 
    "msg": "Failed to connect to the host via ssh: ssh: connect to host redfern2.yaocm.id.au port 22: No route to host\r\n", 
    "unreachable": true
}
