- [Instructor] This is the second course in a two part series covering the Red Hat RHCSA EX200 certification. If you haven't taken the first course, I encourage you to do so. In the first course, we created a CentOS8 USB installation thumb drive. Then we installed CentOS on a physical machine. After that, we prepared our CentOS8 host for KVM virtualization. We then interactively installed a CentOS8 guest virtual machine. We also did an automated install using a kickstart file. And with a bit of wizardry, we injected that kickstart file inside a booting VM. We then configured a virtual graphics card and input devices in KVM. In the next chapter, we booted into two different emergency and recovery modes that we'd use to recovery a broken system and or reset a system administrator's password. We use systemd to manage services. We configured live and saved network configuration. We configured a network time protocol client. We created at and cron jobs and limited access to them. There are a lot of shortcuts and power tools for the Linux command line. In the next chapter, we used both input and output redirection. We used grep and regular expressions to find search criteria in files. We used tar along with compressors to archive files. We used the command line tools to create, copy, move and delete files. We learned the basics of editing texts with vim and we learned about system logging using rsyslog and journald. In the last chapter, we installed and removed both packages and package groups using DNF. We learned to query the RPM database and output the information using complex RPM package name filters. We also searched for packages using DNF and managed entire operating system updates, including updating the kernel and managing kernel modules. That course is the foundation course for this one. Since in that course, we created our virtual machines that we will use in this course, it is imperative that you take that course before taking this one.
