RHCE 8 - Deploy Apache Web Server
Looking at deploying the web server on RHEL 8 it is more than just installed the httpd package. Se need to to install httpd-manual for documentation and we may need to install firewalld if we want to protect the system. We also will need to configure the web server, even if it to listen just on IPv4. We will need web content before starting the services and enabling the port in the firewall. More than you at first think. This is where Ansible comes and why RH294 and the EX294 exam now are part of your RHCE certification. This practical demonstration of Ansible shows how to install multiple yum packages and how to use loops to start services. We also use variable from Ansible facts to set the List address on each web server.
