Red Hat System Administration I (RH124)

The first certification that I’m attempting is the Red Hat Administration 1 (RH124). Given my limited experience with Red Hat, it’s best to start at the beginning and get the basics right!

The following is an outline for the certification:

• Get started with Red Hat Enterprise Linux

  Describe and define open source, Linux, Linux distributions, and Red Hat Enterprise Linux

• Access the command line

  Log into a Linux system and run simple commands using the shell.

• Manage files from the command line

  Copy, move, create, delete, and organize files while working from the bash shell.

• Get help in Red Hat Enterprise Linux

  Resolve problems by using local help systems.

• Create, view, and edit text files

  Manage text files from command output or in a text editor.

• Manage local users and groups

  Create, manage, and delete local users and groups, as well as administer local password policies.

• Control access to files

  Set Linux file system permissions on files and interpret the security effects of different permission settings.

• Monitor and manage Linux processes

  Evaluate and control processes running on a Red Hat Enterprise Linux system.

• Control services and daemons

  Control and monitor network services and system daemons with the systemd service.

• Configure and secure SSH

  Configure secure command line service on remote systems, using OpenSSH.

• Analyze and store logs

  Locate and accurately interpret logs of system events for troubleshooting purposes.

• Manage networking

  Configure network interfaces and settings on Red Hat Enterprise Linux servers.

• Install and update software packages

  Download, install, update, and manage software packages from Red Hat and DNF package repositories.

• Access Linux files systems

  Access, inspect, and use existing file systems on storage attached to a Linux server.

• Analyze servers and get support

  Investigate and resolve issues in the web-based management interface, getting support from Red Hat to help solve problems.

I will start by creating notes for each section, which I will come back and link to from here. I plan to use this as a cheat sheet for myself in the future. It’ll save me from having to Google the same stuff repeatedly!
