Today we're talking about how to Deploy a web server apache httpd on RedHat-like Linux systems.
The full process requires four steps that you could automate with different Ansible modules.
Firstly you need to install the httpd package and dependency using the ansible.builtin.yum Ansible module.
Secondly, you need to create the custom index.html with ansible.builtin.copy Ansible module. You could upgrade this step using the template module.
Thirsty you need to start the httpd service and enable on boot and all the dependant using the ansible.builtin.service Ansible module.
Fourthly you need to open the relevant firewall service-related ports using the ansible.posix.firewalld Ansible module.
