To Install Ansible On Oracle Linux 8.8
Introduction:
The Ansible platform is an open-source IT automation and configuration management platform developed by Red Hat that uses human-readable YAML templates to automate repetitive tasks.
Installation Procedure:
Step 1: Check the Oracle Linux Version by using the below command
[root@linuxhelp ~]# cat /etc/os-release
NAME="Oracle Linux Server"
VERSION="8.8"
ID="ol"
ID_LIKE="fedora"
VARIANT="Server"
VARIANT_ID="server"
VERSION_ID="8.8"
PLATFORM_ID="platform:el8"
PRETTY_NAME="Oracle Linux Server 8.8"
ANSI_COLOR="0;31"
CPE_NAME="cpe:/o:oracle:linux:8:8:server"
HOME_URL="https://linux.oracle.com/"

Complete!
Step 6: Check the Ansible version by using the below command
[root@linuxhelp ~]# ansible --version
ansible 2.9.27
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/python3.6/site-packages/ansible
executable location = /usr/bin/ansible
python version = 3.6.8 (default, Jun 14 2023, 10:42:30) [GCC 8.5.0 20210514 (Red Hat 8.5.0-18.0.2)]
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 by using the below command
[root@linuxhelp ~]# ssh-keygen
Generating public/private rsa key pair.
Enter file in which to save the key (/root/.ssh/id_rsa):
Created directory '/root/.ssh'.
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:yK5xYr/KpfLJE2b2aIcrlGY+KAA2xUULhkrAiI/M5j0 root@linuxhelp
The key's randomart image is:
+---[RSA 3072]----+
|* oooo |
|o+.o. . |
|=o. . |
|+*. . . |
|= o. o S |
|..=E=. |
|.* +==+ |
|o =+=Xo |
|. *X=o. |
+----[SHA256]-----+
[root@linuxhelp ~]# ssh-copy-id root@linuxhelp.com
The authenticity of host 'linuxhelp.com (192.168.6.136)' can't be established.
ECDSA key fingerprint is SHA256:38frx9vyZqBXVdtlTHa6oDK17712pJ5V0UAiUDXGWYc.
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@linuxhelp.com's password:
Number of key(s) added: 1
Now try logging into the machine, with: "ssh 'root@linuxhelp.com'"
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 by using the below command
[root@linuxhelp ~]# ssh root@linuxhelp.com
Activate the web console with: systemctl enable --now cockpit.socket
Last login: Fri Jun 16 23:15:57 2023
[root@linuxhelp ~]# ip a

link/ether 52:54:00:21:7f:e8 brd ff:ff:ff:ff:ff:ff
Step 10: Next run the below commands without password for login user by using the below command.
[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 by using the below command
[root@linuxhelp ~]# exit
logout
Connection to linuxhelp.com closed.
Step 12: Create new ansible project directory and Navigate to Ansible directory by using the below command
[root@linuxhelp ~]# mkdir ~/ansible
[root@linuxhelp ~]# cd ~/ansible/
Step 13: Next you can add the Group servers by using the below command
[root@linuxhelp ansible]# vim hosts
linuxhelp.com ansible_user=root
Step 14: List and ping the host single group as well by using the below commands
[root@linuxhelp ansible]# ansible -i hosts --list-hosts all
hosts (1):
linuxhelp.com
[root@linuxhelp ansible]# ansible -i hosts -m ping webserver

Step 15: Next install Apache webserver on the webserver group by using the below command
[root@linuxhelp ansible]# ansible -i hosts -b --become-method=sudo -m shell -a 'yum install -y httpd' webserver
[WARNING]: Consider using the yum module rather than running 'yum'. If you
need to use command because yum is insufficient you can add 'warn: false' to
this command task or set 'command_warnings=False' in ansible.cfg to get rid of
this message.
