Linux For DevOps In One Shot | Complete Beginners to Advanced Linux (Hindi)
Summary of Key Technological Concepts, Features, and Tutorials
1. Introduction to Internet and Networking Basics
- Explanation of how the internet works: fiber optic cables laid under oceans connect data centers to devices.
- Role of servers and clients; different types of servers such as email server, file server, database server, application server, and web server.
- Domain Name System (DNS) and IP addresses linking.
- Basic networking commands explained with practical examples:
ping,netstat,traceroute,nslookup,telnet, andmtr. - Concepts of ports, protocols (TCP/IP), and network interfaces (NIC).
- Tools introduced for network diagnostics and scanning:
net-tools,wireless-tools, andnmap.
2. Operating Systems Overview
- Comparison between Windows and Linux highlighting Linux’s advantages: open-source nature, security, multitasking, and no forced updates.
- Introduction to Linux kernel, shell, and boot loader (GRUB).
- Explanation of Linux system architecture: kernel, shell as an interface, applications, and hardware interaction.
- Overview of different Linux distributions: Ubuntu, Kali, CentOS, Fedora, Arch, Gentoo.
3. Linux Basics and Commands
- File system basics: root folder
/and common directories like/home,/usr,/bin,/etc,/var,/tmp. - Common commands:
ls,pwd,cd,mkdir,rm,touch,cat,echo,head,tail,less,more,cp,mv,wc,diff. - File and directory permissions: read (r), write (w), execute (x) for user, group, and others.
- Numeric representation of permissions (0-7) and usage of
chmodto change permissions. - User and group management commands: creating users (
useradd), changing passwords (passwd), switching users (su), deleting users (userdel), creating groups (groupadd), adding users to groups (gpasswd). - Use of
sudofor superuser privileges. - Changing file ownership with
chownandchgrp. - Introduction to symbolic (soft) and hard links, their differences, and commands to create them (
ln,ln -s).
4. Remote Access and Cloud Setup
- Using SSH to connect to remote Linux servers, including AWS EC2 instances.
- Creating AWS accounts and launching EC2 instances (free tier eligible).
- Using key pairs (public/private keys) for secure SSH access.
- Tools for remote desktop access: SSH, RDP, AnyDesk.
- Copying files between local and remote systems using
scpand syncing withrsync. - Basic AWS EC2 instance management: starting, stopping, rebooting instances.
5. Package Management and Software Installation
- Different package managers:
apt(Ubuntu/Debian),yum(CentOS/RedHat),dnf(Fedora),pacman(Arch),portage(Gentoo). - Installing, updating, and removing packages (e.g., Docker).
- Importance of keeping the system updated (
apt-get update).
6. Compression and Archiving
- Using
zipandunziputilities for compressing and extracting files. - Using
tarwith flags (cfor create,xfor extract,vfor verbose,zfor gzip compression,ffor file name) for archiving and compressing files. - Explanation of
.tar.gzfiles and how to handle them.
7. Process and System Monitoring
- Viewing running processes with
psandtop. - Understanding process states: running, sleeping, zombie, terminated.
- Managing processes, including killing processes.
- Checking disk usage (
df), memory usage (free,vmstat). - Using
nohupto run commands in the background and capture output.
8. Advanced Text Processing and Shell Scripting
- Using
awk,sed, andgrepfor text processing, filtering logs, and extracting specific data. - Differences between:
awk(structured data processing),sed(stream editor for unstructured data),grep(pattern matching).
- Examples include extracting log entries, counting occurrences, replacing text in files.
- Introduction to shell scripting basics for automation.
9. Logical Volume Management (LVM) and Storage
- Explanation of physical volumes (PVs), volume groups (VGs), and logical volumes (LVs).
- Creating and managing LVM on AWS EC2 instances with attached EBS volumes.
- Mounting and formatting volumes.
- Benefits of LVM: combining multiple physical volumes into one group and creating flexible logical volumes that can be resized.
