Create a role called apache in "/home/admin/ansible/roles" with the following requirements: --> The httpd package is installed, enabled on boot, and started. --> The firewall is enabled and running with a rule to allow access to the web server. --> template file index.html.j2 is used to create the file /var/www/html/index.html with the output: Welcome to HOSTNAME on IPADDRESS --> Where HOSTNAME is the fqdn of the managed node and IPADDRESS is the IP-Address of the managed node. note: you have to create index.html.j2 file. --> Create a playbook called httpd.yml that uses this role and the playbook runs on hosts in the webservers host group.
