How to install Ansible on Fedora 32 for IT and server automation

How do I install Ansible on Fedora 32 workstation? How can I set up and test Ansible playbooks using my Fedora Linux desktop?

Introduction – Ansible is a free and open source configuration management tool. It is similar to Chef or Puppet. It works over SSH based session and does not need any software or client/agent on remote servers. One can use Ansible to manage Linux, Unix, macOS, and *BSD family of operating systems. This page shows how to install ansible and set up your first Ansible playbook on Fedora Linux 29/30/31/32.

Procedure to install Ansible on Fedora 32

  1. Update your Fedora 32 system, run: sudo dnf update
  2. Install Ansible on Fedora 32, run: sudo dnf install ansible
  3. Upgrade Ansible in Fedora 32, run: sudo dnf upgrade ansible
  4. Set up ssh key-based authentication
  5. Test Ansible

Step 1. Fedora Linux install Ansible

Type the following dnf command to update Fedora box:
$ sudo dnf update
$ dnf search ansible

Find out information about the Ansible package, run:
$ dnf info ansible

Installing Ansbile on Fedora Linux

Finally, type the following dnf command:
$ sudo dnf install ansible

Find the Ansible version

We can verify the Ansible version by running the following command:
$ ansible --version
Sample outputs:

ansible 2.9.13
  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/python3.8/site-packages/ansible
  executable location = /usr/bin/ansible
  python version = 3.8.5 (default, Aug 12 2020, 00:00:00) [GCC 10.2.1 20200723 (Red Hat 10.2.1-1)]

Step 2. Set up ssh keys on a Linux or Unix

First, create the key pair using the ssh-keygen command on your Fedora Linux desktop/workstation:
$ ssh-keygen -t ed25519 -C "Desktop ssh key"
Next, copy and install the public key in remote Linux/Unix/BSD servers using the ssh-copy-id command:
$ ssh-copy-id -i $HOME/.ssh/ user@ubuntu-server-ec2
$ ssh-copy-id -i $HOME/.ssh/ ec2-user@freebsd-server-lightsail
$ ssh-copy-id -i $HOME/.ssh/ vivek@centos-server-linode

Test password less log in using the ssh command:
$ ssh vivek@centos-server-linode
$ ssh ec2-user@freebsd-server-lightsail

Step 3. Test the Ansible

Sample Ansible Fedora Linux set up

Our sample Ansible setup

First create an inventory file as follows on a control machine:
$ vi inventory
Add hostnames/IP address of all remote Linux/*BSD servers:

## my vms/server hosted locally ##

## my vms/servers hosted by AWS (EC2/Lightsail) ##

## my Linode VMs ##

Next run the uptime command command and lsb_release command on two hosts located in my LAN i.e. lanhosts group as user vivek:
$ ansible -u vivek -i inventory -m raw -a 'uptime' lanhosts
$ ansible -u vivek -i inventory -m raw -a 'lsb_release -a' lanhosts

Testing Ansible on Fedora Linux

Step 4. Writing your first Ansible playbook to manage Linux/Unix servers

First, update your inventory file to indicate user name and method to become sudo on the remote server. Here is my updated hosts file displayed with the cat command:
cat inventory
Sample config file:

ansible_user='vivek'           # Username for ssh connection
ansible_become='yes'             # Run commands as root user?
ansible_become_pass='PasswordForVivekUser' # Password for sudo user i.e. ansible_user password
ansible_become_method='sudo'     # How do I become root user? Use sudo.
## my vms/server hosted locally ##
[lanhosts] ansible_python_interpreter='/usr/bin/python2' ansible_python_interpreter='/usr/bin/python3'
## my vms/servers hosted by AWS (EC2/Lightsail) ##
## my Linode VMs ##

A playbook is nothing but scripts/commands that executed on the remote box. Create a playbook named test.yml as follows using a text editor such as vim command/nano command:
vim test.yml
Append the following code:

- hosts: lanhosts
          - name: Get hostname for testing purpose
            command: /bin/hostname
            changed_when: False
            register: hostname
          - debug: var={{ item }}
                    - hostname.stdout

Playbooks in Ansible use Yaml. Next, run it as follows from Fedora Linux workstation/control machine:
$ ansible-playbook -i inventory test.yml
How to run ansible playbook

A note about password stored in an insecure format

Take a close look at the following config directory in inventory file:


It is a bad idea to store password and other sensitive information in clear text format. Let us fix this:
$ vim inventory



ansible_become_pass='{{ my_user_password }}'

Save and close the file. Next create a new encrypted data file named passwords.yml, run the following command:
$ ansible-vault create passwords.yml
Set the password for vault. After providing a password, the tool will start whatever editor you have defined with $EDITOR. Append the following:

my_user_password: your_password_for_ansible_user

Save and close the file. Run it as follows:
$ ansible-playbook -i inventory --ask-vault-pass --extra-vars '@passwords.yml' test.yml

Adding user using the Ansible playbook

Say you need to add a new user named wwwjobs all hosts in lanhosts group. Create a new playbook named add-user.yml:

- hosts: lanhosts
          - name: Add a new user to my Linux VMs with password disabled but allow ssh log in
                    name: wwwjobs
                    comment: "Account to run jobs for our web server"
                    shell: /bin/bash
                    groups: sudo
                    append: yes
                    password: *
          - name: Upload ssh key for user wwwjobs for log in purpose
                    user: vivek
                    state: present
                    manage_dir: yes
                    key: "{{ lookup('file', '/home/vivek/.ssh/') }}"

Run it as follows:
$ ansible-playbook -i inventory --ask-vault-pass --extra-vars '@passwords.yml' add-user.yml

How to add and remove packages

In this example, we are going to add and remove packages using the apt command for all hosts located in linodehosts group. Create a file named ubuntu-software.yml:

- hosts: linodehosts
          - name: Add a list of software on Linode VMs ...
                    name: "{{ packages }}"
                    state: present
                            - vim
                            - unzip
                            - htop
                            - atop
                            - iftop
                            - nmon
                            - sysstat
                            - iotop
                            - nicstat
                            - vnstat
          - name: Delete a list of software from Linode VMs ...
                    name: "{{ packages }}"
                    state: absent
                            - nano

Again run it as follows:
$ ansible-playbook -i inventory --ask-vault-pass --extra-vars '@passwords.yml' ubuntu-software.yml


And there you have it, Ansible set up and tested to manage Linux or Unix boxes. Ansible works very fast for repeated tasks such as adding users in bulk, installing software, configuring *BSD/Linux/Unix boxes. YAML takes a little time to master but easy to learn.
