To Install And Use Ansible On Ubuntu 22.04

Introduction:

Ansible offers open-source automation solutions that simplify processes and operate across diverse environments. By utilizing Ansible, organizations can automate a wide range of tasks effectively. Ansible employs straightforward, human-readable scripts referred to as playbooks for task automation. Additionally, Ansible adheres to key principles, including agent-less architecture, simplicity, scalability, flexibility, idempotence, and predictability.

Procedure:

Step1: Check the OS version using the below command

root@linuxhelp:~# lsb_release -a
No LSB modules are available.
Distributor ID:	Ubuntu
Description:	Ubuntu 22.04.4 LTS
Release:	22.04
Codename:	jammy

Step 2: Check for updates using the below command

root@linuxhelp:~# sudo apt update

root@linuxhelp:~# sudo apt-add-repository --yes -update ppa:ansible/ansible
Repository: 'deb https://ppa.launchpadcontent.net/ansible/ansible/ubuntu/ jammy-date main'
Description:
Ansible is a radically simple IT automation platform that makes your applications and systems easier to deploy. Avoid writing scripts or custom code to deploy and update your applications— automate in a language that approaches plain English, using SSH, with no agents to install on remote systems.

Step 6: After adding repository, Install Ansible using the below command

root@linuxhelp:~# sudo apt-get install ansible
Reading package lists... Done
Building dependency tree... Done
Reading state information... Done
The following packages were automatically installed and are no longer required:
  libflashrom1 libftdi1-2 libllvm13 libwpe-1.0-1 libwpebackend-fdo-1.0-1
Use 'sudo apt autoremove' to remove them.
The following additional packages will be installed:

Setting up ansible (2.10.7+merged+base+2.10.8+dfsg-1) ...
Processing triggers for man-db (2.10.2-1) ...

Step 7: Check the Ansible version use the below command

root@linuxhelp:~# ansible --version
ansible 2.10.8
  config file = None
  configured module search path = ['/root/.ansible/plugins/modules', '/usr/share/ansible/plugins/modules']
  ansible python module location = /usr/lib/python3/dist-packages/ansible
  executable location = /usr/bin/ansible
  python version = 3.10.12 (main, Jul 29 2024, 16:56:48) [GCC 11.4.0]

Step 8: Ansible uses an inventory file to keep track of the servers it manages. Create a file named inventory dot ini using the below command and add the following content

root@linuxhelp:~# nano inventory.ini

[local]
192.168.6.138 ansible_connection=local

Step 9: Playbooks are YAML files that define a series of tasks to be executed. Create a file named playbook.yml using the below command.Add the following content to playbook.yml, which performs a basic task such as installing the vim text editor.

root@linuxhelp:~# nano playbook.yml
---
- name: Install Vim
  hosts: local
  become: yes
  tasks:
    - name: Install vim
      apt:
        name: vim
        state: present

Step 10: To Check Syntax and Verify your playbook syntax before running it using the below command

root@linuxhelp:~# ansible-playbook --syntax-check playbook.yml
[WARNING]: No inventory was parsed, only implicit localhost is available
[WARNING]: provided hosts list is empty, only localhost is available. Note that the implicit localhost does not match 'all'
[WARNING]: Could not match supplied host pattern, ignoring: local

playbook: playbook.yml

Step 11: Execute the playbook using the below command

root@linuxhelp:~# ansible-playbook -i inventory.ini playbook.yml

PLAY [Install Vim] **************************************************************************************************************************************

TASK [Gathering Facts] **********************************************************************************************************************************
ok: [192.168.6.133]

TASK [Install vim] **************************************************************************************************************************************
ok: [192.168.6.133]

PLAY RECAP **********************************************************************************************************************************************
192.168.6.133              : ok=2    changed=0    unreachable=0    failed=0    skipped=0    rescued=0    ignored=0

Step 12: To check Ansible is working or not , we can remove the vim package use the below command

root@linuxhelp:~# apt remove vim
Reading package lists... Done
Building dependency tree... Done
Reading state information... Done
The following packages were automatically installed and are no longer required:
  libflashrom1 libftdi1-2 libllvm13 libwpe-1.0-1 libwpebackend-fdo-1.0-1 vim-runtime
Use 'apt autoremove' to remove them.
The following packages will be REMOVED:
  vim
0 upgraded, 0 newly installed, 1 to remove and 3 not upgraded.
After this operation, 4,025 kB disk space will be freed.
Do you want to continue? [Y/n] y
(Reading database ... 245702 files and directories currently installed.)
Removing vim (2:8.2.3995-1ubuntu2.17) ...
update-alternatives: using /usr/bin/vim.tiny to provide /usr/bin/vi (vi) in auto mode
update-alternatives: using /usr/bin/vim.tiny to provide /usr/bin/view (view) in auto mode
update-alternatives: using /usr/bin/vim.tiny to provide /usr/bin/ex (ex) in auto mode
update-alternatives: using /usr/bin/vim.tiny to provide /usr/bin/rview (rview) in auto mode

Step 13: Again to execute use the below same execute command:

root@linuxhelp:~# ansible-playbook -i inventory.ini playbook.yml

PLAY [Install Vim] **************************************************************************************************************************************

TASK [Gathering Facts] **********************************************************************************************************************************
ok: [192.168.6.133]

TASK [Install vim] **************************************************************************************************************************************
changed: [192.168.6.133]

PLAY RECAP **********************************************************************************************************************************************
192.168.6.133              : ok=2    changed=1    unreachable=0    failed=0    skipped=0    rescued=0    ignored=0

Step 14: To check whether the vim package is installed or not use the below command

root@linuxhelp:~# sudo apt install vim
Reading package lists... Done
Building dependency tree... Done
Reading state information... Done
vim is already the newest version (2:8.2.3995-1ubuntu2.17).
The following packages were automatically installed and are no longer required:
  libflashrom1 libftdi1-2 libllvm13 libwpe-1.0-1 libwpebackend-fdo-1.0-1
Use 'sudo apt autoremove' to remove them.
0 upgraded, 0 newly installed, 0 to remove and 3 not upgraded.

Frequently asked questions ( 5 )

Q

What is Ansible?

A

Ansible is an automation tool that helps you manage and configure complex IT infrastructure, including servers, networks, and applications. It uses an agentless architecture, which means no software needs to be installed on the target nodes.

Q

How does Ansible work?

A

Ansible works by sending scripts (called playbooks) to remote hosts over SSH or other protocols. The playbooks define what actions need to be taken on each host, and Ansible executes those actions in the correct order. This allows you to easily manage multiple nodes from a central location.

Q

What are the advantages of using Ansible?

A

Some key benefits of using Ansible include:
• Agentless architecture, which means no software needs to be installed on target nodes
• Easy to learn and use, even for those without extensive scripting experience
• Fast and efficient, with parallel execution capabilities
• Supports multiple platforms and protocols (e.g., Linux, Windows, Solaris, etc.)
• Extensive community support and thousands of pre-built modules

Q

What are Ansible playbooks?

A

Playbooks are YAML-formatted files that define the desired state of your infrastructure. They contain a list of tasks, which are executed in the order they appear in the playbook. Tasks can include installing software, configuring services, creating users, and more.

Q

How do I write an Ansible playbook?

A

Writing an Ansible playbook involves defining the tasks you want to perform on each host, using a YAML format. You'll need to specify things like:

• The hosts that should receive the playbook
• The tasks to be executed on each host
• Any dependencies or prerequisites for the tasks
