Ansible Configuration

Introduction

This project demonstrates the deployment and configuration of a web server environment using Ansible on AWS Webserver 3 and 4. It covers both static and dynamic inventory methods, automation of Apache installation, image hosting via Amazon S3, and configuration of Ansible playbooks for seamless remote management.

Install Dependencies

Install required Python and Ansible packages: sudo yum install ansible -y sudo yum install python3-boto3 -y

Test Connectivity

ansible -i hosts.txt linux -m ping ansible -i hosts_novars.txt linux -m ping

Run the following commands

ansible linux -m setup ansible linux -m shell -a hostname

Upload Image to S3

Manually upload an image named demo.png to the S3 bucket. This image was used by the web servers.

Creating touch file

touch acs730

Copy a file acs730 to the /tmp/ directory on all remote hosts in the linux group, giving it full permissions (777).

ansible linux -m copy -a "src=acs730 dest=/tmp/ mode=0777" -b

Download a Remote File Using get_url

ansible linux -m get_url -a "url=https://amazon-ssm-ca-central-1.s3.ca-central-1.amazonaws.com/latest/linux_amd64/amazon-ssm-agent.rpm dest=/tmp" -b

Install Apache Webserver

ansible linux –m yum –a "name=httpd state=installed" -b

Start and enable the httpd service

ansible linux –m service –a "name=httpd state=started enabled=yes" -b

Debugging

ansible linux –m service–a "name=httpd –state=started enabled=yes" -b –vvv

Run Ansible Playbooks

Navigate to the Ansible directory and update the S3 bucket name in s3playbook.yml: cd ~/environment/ansiblefinal/

Download the image from the S3 bucket: ansible-playbook s3playbook.yml

Run myplaybook.yml ansible-playbook myplaybook.yml

For dynamic inventory deploy the web application to the web servers:

This task demonstrates how to configure and use Ansible Dynamic Inventory with AWS EC2 instances using the aws_ec2 plugin. Prerequisites Ensure boto3 is installed on your Amazon Linux system: sudo yum install python3-boto3 -y

Step 1: Create Dynamic Inventory File Create a file named aws_ec2.yaml with the following configuration:

plugin: aws_ec2 regions: - us-east-1 keyed_groups: - key: tags.Owner prefix: tag filters: instance-state-name : running compose: ansible_host: public_ip_address

Step 2: Update Ansible Configuration

Edit the Ansible configuration file: sudo vi /ansiblefinal/ansible_dynamic.cfg

Update or add the following lines:

[defaults] #inventory = /home/sungold/projects/seneca/ACS/ACS-project/ansiblefinal/hosts.txt inventory = ./aws_ec2.yml host_key_checking = False retry_files_enables = False interpreter_python = /usr/bin/python3 [inventory] enable_plugins = aws_ec2

Step 3: Verify the Dynamic Inventory Run the following command to view the EC2 instances grouped dynamically: ansible-playbook -i aws_ec2.yml myplaybook.yml
