In this toturial we shall demostrate all the steps to deploy Ansible AWX on RHEL 8.x servers. Ansible AWX is the community version of Ansible Tower, where system administrators will be able to handle Ansible using the GUI interface.<\/p>\n

\nBy default, SELinux is enforcing in CentOS\/RHEL 7\/8. It is recommended to change SELINUX=enforcing to SELINUX=disabled to run Ansible AWX error free:
\n# nano \/etc\/sysconfig\/selinux<\/p>\n
\nSELINUX=disabled<\/p>\n
\n# dnf install https:\/\/dl.fedoraproject.org\/pub\/epel\/epel-release-latest-8.noarch.rpm<\/p>\n
