I. Overview:

Learn how to configure and manage key services integrated with Red Hat Enterprise Linux, and scale up your work with Ansible automation.

Red Hat Services Management and Automation (RH358) is designed for IT professionals with some experience managing Linux systems, who want to learn more about how to manage and deploy network services that are included with Red Hat Enterprise Linux. You will learn how to manually install, configure, and manage basic configurations of these services, and then use Ansible to automate your work in a scalable, repeatable manner.

This course is based on Red Hat Ansible Automation Platform 2.4 and Red Hat Enterprise Linux 9.4.

Course content summary

• Providing key network services using software included with Red Hat Enterprise Linux 9, including:
  • DNS with Unbound and BIND9
  • IPv4 and IPv6 network autoconfiguration withDHCP and DHCPv6 servers
  • Client email transmission
  • Printing service with IPP Everywhere and CUPS
  • NFS and SMB protocol file sharing
  • SQL database service with MariaDB
  • Web services using Apache HTTPD and Nginx.
• Configuring advanced networking for server use cases, including network bonding
• Using Ansible to automate the manual deployment and configuration tasks covered in this course

II. Duration: 5 days (40 hours)

III. Objectives:

Business Outcome Statement

• This course will help your IT staff develop key skills in managing and automating common services that support and are used by your business-critical applications. This can reduce time to deployment, improve reliability, and help ensure architectural compliance, allowing resources to be spent on improving rather than just running your business.

Student Outcome Statement

• In this course, you will learn the system administration skills needed to set up and provide key network services that are frequently used by servers and their applications in enterprise data centers. You will gain an understanding of how to manually manage these services, and you will also prepare Ansible Playbooks to automate manual configuration tasks and perform them at scale.

IV. Intended Audience:

• Linux system administrators, platform engineers, developers, and other IT professionals with some Ansible experience who are interested in learning how to manage and automate the deployment, configuration, and operation of key network services included with Red Hat Enterprise Linux.

V. Prerequisites:

• RHCSA-level skills with Linux system administration
• Working knowledge of Ansible (RH294 or equivalent skills and experience)

VI. Course outlines:

1. Managing Network Services

Discuss and review key tools and skills needed to manage network services.

2. Configuring Link Aggregation

Configure and troubleshoot advanced network interface functionality, including network bonds.

3. Managing DNS and DNS Servers

Explain the operation of the Domain Name System (DNS), troubleshoot DNS issues, and configure name servers that are caching-only or that are authoritative for a DNS zone.

4. Managing DHCP and IP Address Assignment

Explain and configure services that automatically assign IPv4 and IPv6 addresses, including DHCP, DHCPv6, and SLAAC.

5. Managing Printers and Printing Files
