Step 6: Check the Ansible version by using the below command
[root@linuxhelp ~]# ansible --version
ansible [core 2.12.2]
config file = /etc/ansible/ansible.cfg
configured module search path = ['/root/.ansible/plugins/modules', '/usr/share/ansible/plugins/modules']
ansible python module location = /usr/lib/python3.9/site-packages/ansible
ansible collection location = /root/.ansible/collections:/usr/share/ansible/collections
executable location = /usr/bin/ansible
python version = 3.9.18 (main, Sep 7 2023, 00:00:00) [GCC 11.4.1 20230605 (Red Hat 11.4.1-2.1.0.1)]
jinja version = 2.11.3
libyaml = True
Step 7: Open your /etc/hosts file and add the following using the below command
[root@linuxhelp ~]# vim /etc/hosts
Step 8: Now generate SSH Key.copy, this created ssh key for another remote server
[root@linuxhelp ~]# ssh-keygen
Generating public/private rsa key pair.
Enter file in which to save the key (/root/.ssh/id_rsa):
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /root/.ssh/id_rsa
Your public key has been saved in /root/.ssh/id_rsa.pub
The key fingerprint is:
SHA256:9LBEGbYd03rhda982PjxtRmtTia3azPjUJvJVPNzQdc root@linuxhelp
The key's randomart image is:
+---[RSA 3072]----+
| +oo. .o|
| o.o oo o E|
| = .o o +o|
| o +. o .=|
| S .. .o*+|
| +=*B|
| o O+B|
| **+o|
| +== |
+----[SHA256]-----+
[root@linuxhelp ~]# ssh-copy-id root@vm1.linuxhelp.local
The authenticity of host 'vm1.linuxhelp.local (192.168.6.140)' can't be established.
ED25519 key fingerprint is SHA256:zLc8ctMiULvhvu/YUZMD8cwdzVBpLbQFKGNR+Jr+csk.
This key is not known by any other names
Are you sure you want to continue connecting (yes/no/[fingerprint])? 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
root@vm1.linuxhelp.local's password:
Number of key(s) added: 1
Now try logging into the machine, with: "ssh 'root@vm1.linuxhelp.local'"
and check to make sure that only the key(s) you wanted were added.
Step 9: After added the SSH key without any SSH password you can able to access for remote server
[root@linuxhelp ~]# ssh root@vm1.linuxhelp.local
Activate the web console with: systemctl enable --now cockpit.socket
Last login: Fri Mar 15 22:39:23 2024 from 192.168.6.104
[root@linuxhelp ~]#
[root@linuxhelp ~]# ip a

Step 10: Next run the below command without password for login user.
[root@linuxhelp ~]# echo "$(whoami) ALL=(ALL) NOPASSWD:ALL" | sudo tee /etc/sudoers.d/$(whoami)
root ALL=(ALL) NOPASSWD:ALL
Step 11: Exit from Remote Server
[root@linuxhelp ~]# exit
logout
Connection to vm1.linuxhelp.local closed.
