So installieren Sie Ansible AWX auf CentOS 7

Im vorherigen Tutorial habe ich Ihnen gezeigt, wie Sie Ansible AWX über Docker einsetzen können. Inzwischen habe ich zwei Projekte gefunden, die rpm-Pakete für AWX erstellen. Daher werde ich Ihnen in diesem Tutorial zeigen, wie Sie Ansible AWX aus RPM-Dateien auf CentOS 7 installieren können. Ansible AWX ist die OpenSource-Version der Ansible Tower-Software.

Ich werde 3 Server mit CentOS 7 Minimalinstallation und SELinux im permissiven Modus verwenden.

  • 192.168.1.25 AWX-Server
  • 192.168.1.21 client1
  • 192.168.1.22 client2

Minimale Systemanforderungen für AWX Server

  • Mindestens 4 GB Arbeitsspeicher
  • Mindestens 2 CPU-Kerne
  • Mindestens 20 GB Speicherplatz
  • Laufender Docker, Openshift oder Kubernetes

Überprüfen Sie die SELinux-Konfiguration.

[[email protected] ~]# sestatus
SELinux status:                 enabled
SELinuxfs mount:                /sys/fs/selinux
SELinux root directory:         /etc/selinux
Loaded policy name:             targeted
Current mode:                   permissive
Mode from config file:          permissive
Policy MLS status:              enabled
Policy deny_unknown status:     allowed
Max kernel policy version:      28
