Red Hat Enterprise Linux 10 introduces powerful automation capabilities through RHEL System Roles, enabling consistent and repeatable configurations across multiple hosts using Ansible Automation Platform playbooks. This approach simplifies large-scale deployments, reduces human error, and ensures compliance.
You Should Know:
1. Key RHEL System Roles
RHEL System Roles are pre-built Ansible roles for configuring essential system components:
– Network (rhel-system-roles.network)
– Firewall (rhel-system-roles.firewall)
– SELinux (rhel-system-roles.selinux)
– Timesync (rhel-system-roles.timesync)
– Storage (rhel-system-roles.storage)
2. Installing RHEL System Roles
sudo dnf install rhel-system-roles -y
3. Example: Automating Firewall Configuration
Create an Ansible playbook (`firewall.yml`):
<ul> <li>name: Configure Firewall with RHEL System Role hosts: all become: yes vars: firewall_service: </li> <li>http </li> <li>https </li> <li>ssh roles: </li> <li>role: rhel-system-roles.firewall
Run the playbook:
ansible-playbook -i inventory.ini firewall.yml
4. Managing Network Configurations
Example playbook (`network.yml`):
<ul> <li>name: Configure Network Interfaces hosts: all become: yes vars: network_connections: </li> <li>name: eth0 type: ethernet ip: address: </li> <li>192.168.1.10/24 gateway4: 192.168.1.1 dns: </li> <li>8.8.8.8 roles: </li> <li>role: rhel-system-roles.network
Execute:
ansible-playbook -i inventory.ini network.yml
5. Automating SELinux Policies
Playbook (`selinux.yml`):
<ul> <li>name: Enforce SELinux Policies hosts: all become: yes vars: selinux_policy: targeted selinux_state: enforcing roles: </li> <li>role: rhel-system-roles.selinux
Run:
ansible-playbook -i inventory.ini selinux.yml
6. Cockpit Web Console Integration
Enable Cockpit for GUI-based management:
sudo systemctl enable --now cockpit.socket
Access via:
https://<server-ip>:9090
What Undercode Say:
Automating RHEL administration with System Roles ensures scalability, security, and efficiency. Key takeaways:
– Use Ansible playbooks for repeatable deployments.
– Leverage predefined roles for firewall, network, and SELinux.
– Cockpit provides a web-based management interface.
– Automation reduces human error and enforces compliance.
Expected Output:
PLAY [Configure Firewall with RHEL System Role] TASK [Gathering Facts] ok: [bash] TASK [rhel-system-roles.firewall : Configure firewall] changed: [bash] PLAY RECAP server1 : ok=2 changed=1 unreachable=0 failed=0 skipped=0 rescued=0 ignored=0
Prediction:
As enterprises adopt Infrastructure as Code (IaC), RHEL System Roles will become a standard for Linux automation, reducing manual configurations by 40% in large-scale environments.
