Enabling PXE BootĪ specific series of commands enable PXE booting of the systems. Of most import here is that the /srv/data/ be created on the infrastructure node, either manually or by the playbook. Now add the nginxinc.nginx role you cloned to the infra.yml playbook and execute the ansible-playbook command again. The entry for server_name needs to match the full hostname of the infrastructure system. Just clone the role into the roles/ folder: $ cd rolesĪfter that, open the host_vars/Hostname.yml file again and save the configuration for Nginx ( Listing 2). You need to support your TFTP service with an Nginx server that can host the Kickstart files for Anaconda, for example.Ī prebuilt Ansible role for this job, directly from the Ansible developers, works wonderfully on CentOS systems. That's not what the protocol is made for. Not all files for the automated RHEL or CentOS installation can be submitted to the installer over TFTP. The use of Ansible and the prebuilt modules definitely saves you some work. If you are wondering why I do not go into more detail concerning the configuration of the firewall (i.e., firewalld), the chosen roles take care of this automatically and open the required ports for the respective services. The individual work steps of the two Playbooks then flash by on your screen. You need to enforce this by typing the command: ansible-playbook -i hosts infra.yml Ansible is prepared well enough to roll out the TFTP and DHCP servers.
