Optional if you want to install a virtual environment, but not required
**Download and install Miniconda:
curl -OL https://repo.continuum.io/miniconda/Miniconda3-latest-Linux-x86_64.sh bash Miniconda3-latest-Linux-x86_64.sh
**You will be prompted several times during the installation process. Review the terms and conditions and select “yes” for each prompt.
*Restart your shell session for the changes to your PATH to take effect.
exec bash -l
*Create a new virtual environment for Ansible:
conda create -n ansible-dev python=3
*Activate the new environment:
conda activate ansible-dev
*Check your Python version:
sudo apt update sudo apt install software-properties-common sudo apt-add-repository --yes --update ppa:ansible/ansible sudo apt install ansible ansible-galaxy collection install community.general
- Verify that Ansible is installed:
By default, Ansible’s configuration file location is
/etc/ansible/ansible.cfg. In most cases, the default configurations are enough to get you started using Ansible. In this example, you will use Ansible’s default configurations.
- To view a list of all current configs available to your control node, use the
ansible-configcommand line utility.
Create an Ansible Inventory
Ansible keeps track of its managed nodes using an inventory file located in
/etc/ansible/hosts. In the inventory file, you can group your managed nodes and use these groups to target specific hosts that make up your infrastructure
- Add your nodes to the default inventory file.
host file with alias for server addresses
- so you can use 'server1' in your ansible file to refer to 192.168.1.1
[webserver] server1 ansible_ssh_host=192.168.1.1 [fileserver] server2 ansible_ssh_host=192.168.2.2
Host file with just ip addresses
[webserver] 192.168.20.222 [fileservers] 192.168.1.1
Each bracketed label denotes an Ansible group . Grouping your nodes by function will make it easier to run commands against the correct set of nodes.
The /etc/ansible directory will not exist by default in some environments. If you find that this is the case, create it manually with the following command:
If you are using a non-standard SSH port on your nodes, include the port after a colon on the same line within your hosts file (203.0.113.1:2222).
Test connection to server
ansible all -u root -m ping --private-key ~/.ssh/ansible
Create a playbook
--- --- - hosts: webserver tasks: - name: install apache package: name: apache2 state: latest - hosts: fileserver tasks: - name: install nginx package: name: nginx state: latest
