Unix IBM AIX System Administration Zero to Hero for Beginner

Create your Azure free account to receive 200 credits, sign in with your Gmail, verify email, and access the Azure portal with a virtual machine, databases, and storage.

Learn how to set up AIX practice environments using IBM hardware racks or IBM Cloud, with Power servers, enterprise setup, and 200 credits in the first month.

Explore cloud options for installing AIX—IBM Cloud and Azure—using Skytap, upgrading to a 200 credit trial, and selecting a minimal 2gb ram, 40gb disk AIX template (versions 6.1–7.2).

Create a SkyTap vm on Azure, deploy an AIX 7.2 TLS3 SP2 image, configure 2 GB RAM and 40 GB disk, attach a static public IP, and log in.

Explore shell terminals and the Bash family, compare Bash with other shells like zsh and tcsh, and learn why Bash is favored for autocompletion and scripting.

Explore how HMC and VIOS manage IBM Power servers and AIX environments, with HMC as a browser-based appliance for multiple servers and VIOS dividing RAM, CPU, and storage for LPAR/VM.

Explore the Linux file system hierarchy rooted at slash, learn absolute paths, and understand how mounting a new disk creates a /test branch under the root for system organization.

Learn the pipeline concept in Unix and Linux, using pipes to pass command output to subsequent commands. Filter results with multiple pipeline stages to reach the desired output.

Learn essential unix commands for daily use across unix flavors, including ls, cd, pwd, cp, mv, cat, grep, sudo, redirection, man, hostname, and basic permissions.

Master essential unix commands for beginners, including ls and man, cd and pwd, cp, mv, rm, touch, mkdir, grep, su and sudo, plus hidden files, permissions, and output redirection.

Learn to edit files on unix/linux using vim and nano, understand insert mode, and master save and quit commands for efficient command-line editing.

Master redirection operators to capture stdout and stderr, append or overwrite files, and send output to dev/null, enabling reliable reporting in Unix IBM AIX system administration.

Explore SMITTY and SMIT in AIX, a system management interface for performing user management, software installation, and configuration via menus or command line; understand logs, scripting, and best practice.

Explore Linux file permissions by reading ls -l output to identify owner, group, size, date, and access rights; understand file types, directories, and links and how they affect permissions.

Learn how Unix permissions are organized into user, group, and others, with read, write, and execute flags, and how to change these modes using plus and minus signs.

Learn how numeric permissions map to read, write, and execute for user, group, and others, and how chmod 644, 755, and 777 control access; beware dash r for recursive changes.

Understand Unix permissions and use groups to control directory access efficiently. Automate access changes by adding or removing group members, reducing repetitive tasks when staff join or leave.

Learn how to manage file ownership and permissions on Unix AIX, using chown and chmod commands, including recursive changes and ownership group scenarios.

Learn how to transfer files between Windows and Linux/Unix using SFTP or SCP, with GUI tools like WinSCP or FileZilla and command-line scp, including permissions, destinations, and network considerations.

Master user management on aix and unix systems by creating, deleting, and resetting passwords with mkuser or useradd. Understand uid, gid, shell, and home directory in /etc/passwd.

Master unix user management by viewing who is logged in, switching to root, and setting or resetting passwords; enforce security with login locks and removing remote-shell access.

Explore the su command to switch to another user, typically root, and understand root password requirements. Compare su dash versus non-dash behavior and its impact on your working directory.

Learn to manage access in AIX using role based access control, assigning file system administration, password reset, and network configuration tasks through defined roles like ISSO, without always using root.

Learn how to assign and manage roles in Unix AIX, granting domainAdmin, sesPolicy, and sesConfig to control passwords and security policies, and switch roles for privileged tasks.

discover how sudo lets trusted users run privileged commands, compare roles versus sudoers, edit with visudo, and manage permissions, password prompts, and audit logs for secure system administration.

Learn to manage services across Unix, Solaris, Oracle, and AIX with src and lssrc, listing, starting, stopping, or refreshing subsystems using -a, -s, or -g, and active or inoperative statuses.

Master managing AIX services using lssrc -a, filter active vs inoperative subsystems, and stop, start, or kill by pid; distinguish single and group services for troubleshooting.
