To Install And Configure Ansible On Oracle Linux 8.5
Introduction:
Ansible is an open-source platform for IT configuration management (CM) and automation developed by Red Hat. It uses human-readable YAML templates to automate repetitive tasks without requiring advanced programming skills.
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="8.5"
Step 2: Update the DNF Package Repository cache with the below command
[root@linuxhelp ~]# sudo dnf makecache
Oracle Linux 8 BaseOS Latest (x86_64) 22 kB/s | 3.6 kB 00:00
Oracle Linux 8 BaseOS Latest (x86_64) 10 MB/s | 49 MB 00:04

Complete!
Step 5: 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, Nov 10 2021, 06:50:23) [GCC 8.5.0 20210514 (Red Hat 8.5.0-3.0.2)]
Step 6: Open your /etc/hosts file and add the following using the below command
[root@linuxhelp ~]# vim /etc/hosts
Step 7: 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):
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:
SHA256:1td2AGrQNdM3MOrrEcrhbiLA33B0EHkg0O2OTVDGyws root@linuxhelp
The key's randomart image is:
+---[RSA 3072]----+
| .o.+==. .=+. |
| oo= o...+o..|
| + + o. ...|
| E * +. . . |
| . B S..o. o .|
| o o *o o.o. . |
| o + + o |

| . o. . |
+----[SHA256]-----+
[root@linuxhelp ~]# ssh-copy-id root@vm1.linuxhelp.local
/usr/bin/ssh-copy-id: INFO: Source of key(s) to be installed: "/root/.ssh/id_rsa.pub"
The authenticity of host 'vm1.linuxhelp.local (192.168.6.121)' can't be established.
ECDSA key fingerprint is SHA256:b52vwlrAIYgldH0BCe0RRtFJZJWoqiTZzL5XusRcpVg.
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 8: 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

Step 9: Next run the below commands 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 10: Exit from Remote Server
[root@linuxhelp ~]# exit
logout
Connection to vm1.linuxhelp.local closed.
Step 11: Create new ansible project directory and Navigate to Ansible directory
[root@linuxhelp ~]# mkdir ~/ansible
[root@linuxhelp ~]# cd ~/ansible/
Step 12: Next You can add the Group servers by using the below command
[root@linuxhelp ansible]# vim hosts
[webserver]
Vm1.linuxhelp.local ansible_user=root
Step 13: Also list and ping the host single group as well.by using the below commands.
[root@linuxhelp ~]# ansible – I hosts –list-hosts all
hosts (1):
vm1.linuxhelp.local
[root@linuxhelp ansible]# ansible -i hosts -m ping webserver
vm1.linuxhelp.local | SUCCESS => {
"ansible_facts": {
"discovered_interpreter_python": "/usr/libexec/platform-python"
},
"changed": false,
Step 14: 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.
