Linux Essentials for Amazon Web Services

Launch a Linux instance in AWS, download a key pair, open a security group for SSH, then connect with an SSH client using the public IP or DNS.

Explore the linux file system hierarchy from the root, examining key directories such as /home, /data, /usr, /bin, /lib, and /media to understand user data and system configuration.

Master Linux basics for AWS environments: navigate the filesystem, view the system information, and manage files with ls, pwd, cp, mv, rm, mkdir, find, head, and tail.

Explore Linux editors like vi and ed, create and edit files, and master saving techniques. Learn to zip and unzip files with zip and unzip utilities on Linux.

Manage linux users and groups, including root and system accounts, by understanding user ids, group ids, home directories, and sudo privileges.

Explore how the Linux shadow file stores password data, including last change date, expiry, min/max password age, inactivity, and grace periods, and learn how to view, edit, and lock users.

Learn linux permissions for files and directories, managing user, group, and others with read, write, and execute rights, viewing with ls -l and setting via chmod.

Explore managing Linux processes with ps, top, and jobs control, handle foreground and background tasks, and learn to start, suspend, list, and terminate tasks while monitoring memory and CPU usage.

Explore linux package management, comparing rpm and yum, understanding dependencies, repositories like epel, and how to install, update, and verify software on linux systems.

Configure and verify hostnames, explore basic network commands for linux, including dns queries, port status, routing, and output redirection for aws environments.

Extend an existing volume in Linux on AWS by identifying the current filesystem, expanding the volume size, and updating the partition and filesystem to reflect the new capacity.

Create a new user on an EC2 instance, enable password authentication, set a login password, and log in by password without using a key.
