Part-1 Red Hat System Administration III (RH254)
Live Lecture 1-14 
 

Red Hat System Administration III: Data Center Services for Red Hat Enterprise Linux 7 (RH254) is designed for experienced Linux® system administrators who hold a Red Hat Certified System Administrator (RHCSA®) credential or possess equivalent skills and want to broaden their ability to administer Linux systems at an enterprise level. The Linux course is focused on deploying and managing network servers running caching domain name service (DNS), MariaDB, Apache HTTPD, Postfix SMTP null clients, network file sharing with network file system (NFS) and server message block (SMB), iSCSI initiators and targets, advanced networking and firewall configurations, and the use of bash shell scripting to help automate, configure, and troubleshoot the system. With this course, you can broaden your ability to administer Linux systems and prepare for your Red Hat Certified Engineer (RHCE) exam training.
