SUSE Linux System Administration

This instructor led SUSE Linux System Administration training course is designed to teach the key administration, security, networking and performance tasks required on a SUSE Linux Enterprise Server (SLES).

Similarly, the course is targeted to closely follow the official Linux Professional Institute (LPI) and CompTIA Linux+ certification curriculums.

Exercises and examples are used throughout the course to give practical hands-on experience with the techniques covered.

The delegate will learn and acquire skills as follows:

• Performing administrative tasks via supplied tools (YaST) and the command line
• Comparison and management of SUSE file systems
• Configuring labels and UUIDs
• Understanding Logical Volume Management
• Listing, creating and removing swap space
• Managing users and groups
• Configuring the environment and user limits
• Extended permissions and sudo
• Installing software packages and updating a SUSE server
• Understanding GRUB and the startup process
• Creating and managing Systemd units and services
• Changing run levels and system shutdown
• Configuring local and remote printers
• Managing processes and automated tasks
• Configuring SSH and encrypting data
• IPv4 and IPv6 networking
• Understanding network protocols
• Configuring firewalld
• Utilising terminal multiplexers
• Configuring local and network time
• Remote system administration
• Creating backups and compressing data
• Modifying language and time zone settings
• Configuring virtualisation and understanding containers
• Understanding hardware and device files
• Configuring system logging and rotating logs

The SUSE Linux System Administration training course is suitable for novice Linux System Administrators, Programmers and other technical IT staff who need to acquire administration knowledge of the key administrative, networking, performance and security tasks required on a SUSE Linux operating system within the Enterprise.

Delegates who wish to work towards achieving the Linux Administrator LPIC-1 or CompTIA Linux+ certifications will find this course a good basis for LPIC-1: 101-500 and 102-500 exams or CompTIA Linux+: LX0-103, LX0-104 and XKO-004 exams.

The appendixes also include other related topics that would be useful reading for delegates preparing for certification.

On completion of this course the delegate will have the required technical knowledge to administer a SUSE Linux server within the Enterprise. They will have gained practical experience of configuring administrative, networking, performance and security aspects of a SUSE Linux Enterprise system (SLES).

The delegate will possess the essential knowledge required to study towards the Linux Administrator LPIC-1 and CompTIA Linux+ certifications.

This course together with the Linux Introduction and Linux Shell Programming or the combined Linux Fundamentals course will aid the delegate in their preparation for the following exams:

• Linux Administrator LPIC-1: 101-500 and LPI 102-500
• CompTIA Linux+: LX0-103, LX0-104 and XK0-004

Attending this course will help the delegate gain many of the skills and product knowledge requirements as outlined in the exams objectives. Studying this course and its associated reference materials can form part of the preparation to achieve certification. Experience, practice, self-study and aptitude are also key requirements for exam success.

Before taking any exam, ensure you have the recommended experience. The LPI and CompTIA websites list all exam requirements and these are updated regularly.

Exams are not included as part of the course.

This SUSE Linux System Administration course assumes good knowledge of the Linux operating system in an Enterprise environment to the level covered in the Linux Introduction course. Alternatively, relevant experience of UNIX or Linux servers is required, preferably within an enterprise environment.

Knowledge of Linux Shell Programming to the level covered on the Linux Shell Programming course would also be beneficial.
