Dans le tutoriel précédent, je vous ai montré comment déployer Ansible AWX via docker. Entre-temps, j'ai trouvé deux projets qui créent des packages RPM pour AWX. Dans ce didacticiel, je vais donc vous montrer comment installer Ansible AWX à partir de fichiers RPM sur CentOS 7. Ansible AWX est la version OpenSource du logiciel Ansible Tower.
J'utiliserai 3 serveurs avec une installation minimale de CentOS 7 et SELinux en mode permissif.
- 192.168.1.25 Serveur AWX
- 192.168.1.21client1
- 192.168.1.22client2
Configuration minimale requise pour le serveur AWX
- Au moins 4 Go de mémoire
- Au moins 2 cœurs de processeur
- Au moins 20 Go d'espace disponible
- Exécuter Docker, Openshift ou Kubernetes
Vérifiez la configuration de SELinux.
[[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 [[email protected] ~]#
