第 23 章 Configuring SELinux by using RHEL system roles

Procedure

1. Create a playbook file, for example, ~/playbook.yml, with the following content:

   ---
   - name: Managing SELinux
     hosts: managed-node-01.example.com
     tasks:
       - name: Restore SELinux context
         ansible.builtin.include_role:
           name: redhat.rhel_system_roles.selinux
         vars:
           selinux_restore_dirs:
             - /var/www/
             - /etc/

   The settings specified in the example playbook include the following:

   selinux_restore_dirs: <list>

   Defines the list of directories on which the role should reset the SELinux context.

   For details about all variables used in the playbook, see the /usr/share/ansible/roles/rhel-system-roles.selinux/README.md file on the control node.

2. Validate the playbook syntax:

   $ ansible-playbook --syntax-check ~/playbook.yml

   Note that this command only validates the syntax and does not protect against a wrong but valid configuration.

3. Run the playbook:

   $ ansible-playbook ~/playbook.yml
