Linux System & Services Administration with Automation course prepares students to become a professional Linux administrator. This course also prepares the students for  Red Hat Certified System Administrator (RHCSA) & Red Hat Certified Engineer (RHCE) certification exams. This course begins from scratch and gradually takes to a professional level. This is an extensive course to learn Linux Administration in depth. We assure that after taking this course, students will be able to work in Level 1 to Level 3 Linux jobs. The course syllabus has been divided into four modules.

In first module, Basics of Linux Administration, students learn basic Linux commands which are frequently used in day to day life. Students learn Linux installation, core Linux commands, methods of getting help, vi/vim editor, string manipulation tools, accessing Linux file system, using redirection operators, managing local users and groups, control access to files, monitoring and managing Linux processes. This part of the course also lays strong foundation on the top of which rest of the course is designed.

In the second module, Linux System Administration, students learn system administration skills like installing and updating software packages, installing Red Hat Enterprise Linux, controlling boot process, controlling services and daemons, running containers, scheduling future tasks, analyzing and storing logs, tuning system performance, managing basic storage, managing storage stack, managing networking, configuring and securing SSH, archiving and transferring files, accessing network attached storage, managing SELinux security, managing network security, analyzing servers and getting support.

The third module is Linux Services and Security Administration. In this part of the course, students learn how to configure DNS server, iSCSI shared storage, NFS server, SAMBA server, MySQL/MariaDB database server, Apache httpd & nginx Web server, Mail server, LDAP server, Kerberos server, VPN server, basics of cybersecurity & detecting and responding to security breaches. At the end of this course, students will be able to manage network services and protect them from security attacks.

In the fourth module, Linux Automation using Ansible, students learn how to automate configuration of Linux systems using ansible playbooks. They learn what is ansible, deploying ansible, implementing playbooks, managing variables and facts, implementing task control, deploying files to managed hosts, managing large projects, simplifying playbooks with roles, troubleshooting ansible & automating Linux administration tasks.

To reinforce and evaluate students learning, they are given assignments after each unit. At the end of each module, there will be live practical test. These assignments and practical tests will prepare students to crack interview, manage real time system as well as it will make them confident to attend Red Hat RHCSA & RHCE Certification exams.

The assignments and tests are prepared in such a way that it prepares the students to work in production enviromnet, succeed in the interviews and pass the certification exams.
