On this page. In the, I showed you how to deploy Ansible AWX via docker. In the meantime, I've found two projects that build rpm packages for AWX. So in this tutorial, I will show you how to install Ansible AWX from RPM files on CentOS 7. Ansible AWX is the OpenSource version of the Ansible Tower software. I will be using 3 servers with and SELinux in permissive mode.
192.168.1.25 AWX Server. 192.168.1.21 client1. 192.168.1.22 client2 Minimum System Requirements for AWX Server.
At least 4GB of memory. At least 2 cpu cores. At least 20GB of space. Running Docker, Openshift, or Kubernetes Check the SELinux configuration. First, nice work. Thank you for putting all of this together.
Though my being a SysAdmin, and thus lazy by definition. Might I offer a few changes for consideration? Installing the packages seperately just extends things. Install all of the packages at the same time, where it makes sense. Yum -y install postgresql96-server rabbitmq-server wget memcached nginx ansible) This allows for fewer steps and inturn less chance of the fat-fingers. Second, less steps.
All of the steps where you are enabling and starting services in two commands, can be done in one step. The worse case of this being the awx services. (systemctl start -now awx-cbreceiver awx-celery-beat awx-celery-worker awx-channels-worker awx-daphne awx-web) Any errors or issues are still apparent, but again, less chance for screw-ups to happen.
Last, it is a better option to leave the default sudoers file alone. Your additions should be placed in a purposefully named file in /etc/sudoers.d. Which can then be written as a single line of commands and scrapped into the terminal for use. Echo 'ansible ALL=(ALL) NOPASSWD: ALL' /etc/sudoers.d/ansibleuser && chmod 600 /etc/sudoers.d/ansibleuser).
