Make HTTPD Service idempotence in Nature using Ansible

ARTH - Task 11.3.

Task Description:

?? 11.3 Restarting HTTPD Service is not idempotence in nature and also consume more resources to suggest a way to rectify this challenge in Ansible playbook.

Let's solve this problem by performing some task:

• Create an Ansible playbook to configure yum in the managed node.
• Install apache webserver httpd in the managed node.
• Configure the webserver.

Ansible Configuration File

#vim /etc/ansible/ansible.cfg

In the above ansible.cfg file mention, the path of the inventory file and also mention that host key checking is false.

Ansible inventory file:-

The Ansible inventory file defines the hosts and groups of hosts upon which commands, modules, and tasks in a playbook operate. The file can be in one of many formats depending on your Ansible environment and plugins. ... If necessary, you can also create project-specific inventory files in alternate locations.

Now check the connectivity with Target Node using the command 

# ansible all -m ping

Create a configuration file for httpd

Here I have created a configuration file named httpd.conf

and the variable stored in the http_var.yml file

Create an Ansible Playbook:

In this playbook, we have configured yum, installed httpd, and configured it.

Now run the playbook

# ansible-playbook httpd_yum.yum

Here you can see the playbook run successfully.

• let's check yum is configured or not, we can check that using the command

# yum repolist

now you can see that it is configured successfully.

• check httpd is installed or not, we can check that using command

# rpm -q httpd

Now you can see it is installed successfully.

• check whether the configuration file is placed in target node or not.

Here you can see httpd.conf that we created is placed and configured successfully.

Thank You....
