ARTH TASK 12

I have Configured Master Node as Controller node of Ansible, created ansible configuration file in the ansible workspace and specified my inventory path

🔹Inventory: A database containing the list of worker nodes or system upon which configuration has to be performed

🔹Check the connectivity to all the nodes using command

ansible all -m ping → this command goes to all the node and perform ping operation

let’s begin with configuring the target nodes as web servers:

Here, I have created a single playbook where I have created two different plays. One play is for configuring the target nodes as webservers and the second play is for configuring the localhost as the Haproxy server.

🔹playbook for configuring the target nodes as webservers:

🔹This playbook will :

  1. attach mount my RHEL8 dvd containing different software with the node
  2. 2.create BaseOS & AppStream Yum Repo
  3. Installs httpd package from the yum repo that we created
  4. copy the content inside root directory of apache-webserver (/var/www/html/)
  5. Start httpd services

🔹This playbook will :

  1. Installs the HAproxy package, used for load balancing purpose
  2. I have a pre-created configuration template in which I have used some of the Jinja2 programs in order to dynamically identify the IP of the backend servers, so this step will copy this template to the destination folder.

🔹Given is the image of the configuration file that i have copied to slave nodes using template module.

🔹Let’s run the playbook

🔹The load balancer has been configured successfully:

  Installing Python3:   $ yum install python3 -y Installing the boto3 library:  $ pip3 install boto Creating a inventory directory: $ mkdir -p /opt/ansible/inventory $ cd /opt/ansible/inventory Creating a file aws_ec2.yaml in the inventory directory with the following configuration: plugin: aws_ec2 aws_access_key: <YOUR-AWS-ACCESS-KEY-HERE> aws_secret_key: <YOUR-AWS-SECRET-KEY-HERE> keyed_groups: - key: tags prefix: tag Open /etc/ansible/ansible.cfg and find the [inventory] section and add the following line to enable the ec2 plugin: [inventory] enable_plugins = aws_ec2 Now let’s test the dynamic inventory configuration by listing the EC2 instances: $ ansible-inventory -i /opt/ansible/inventory/aws_ec2.yaml --list The above command returns the list of EC2 instances with all its parameters in JSON format. Now, check if Ansible is able to ping all the machines returned by the dynamic inventory:  ansible all -m ping Dynamic inventory setup done. Launch...
