List of Linux commands for Server Administrators

Gbadamosi Tajudeen — Thu, 27 Jul 2023 13:44:36 +0000

Linux commands are powerful tools that give users access to the operating system and a range of functions. Each command is a piece of software created to carry out a particular activity, from basic file operations to intricate system management duties. The terminal, which offers a text-based user interface for interacting with the Linux system, is used to execute these instructions.

The flexibility and adaptability of Linux commands is one of its main advantages. To build sophisticated processes and automate operations, they may be combined and used in a variety of ways. A lot of commands also offer input and output redirection, which enables one command's output to be stored to files or supplied as input to another.

Linux commands may be used to handle a variety of things, including files and directories, processes, networking, users, system monitoring, packages, and more. Users have the capabilities to monitor and control their Linux systems efficiently because to the broad variety of commands that are accessible.

Being productive and efficient while dealing with Linux systems may be considerably improved by learning and mastering Linux commands. Users can explore the file system, edit files and directories, analyze system resources, troubleshoot difficulties, and automate repetitive processes by being familiar with the most frequently used commands and their associated parameters.

Overall, Linux commands are the foundation of the Linux operating system and enable users to fully use its capabilities and complete a variety of activities quickly and effectively.

1.
Sudo Su
In Linux, the sudo command enables a user to run a command with the rights of a different user, often the superuser or root. "Sudo" stands for "superuser do." Using the sudo prefix and your password causes a command to run with elevated privileges, giving you momentary administrative access. When you need to carry out actions that need root access, such as system setup, package management, or editing protected files, this might be helpful.

The su command in Linux is used to switch to another user account, typically the superuser or root. "su" stands for "switch user." When you run the "su" command, you are prompted to enter the password for the target user. By default, when you run "su" without specifying a username, it assumes you want to switch to the root user. However, you can also use "su" to switch to other user accounts if you have the necessary permissions.

sudo su has shown in the command line above, helps Switches to the root user. It opens a new shell as the root user, providing a root prompt without requiring a password. To exit from the root user shell, you can type exit.

2.
apt update
For updating the local package lists, Debian-based Linux systems like Ubuntu utilise the apt update command. Your system will always have the most up-to-date knowledge of the software packages that are accessible thanks to the synchronisation of package information from the preset repositories.

When you use the _apt update _ command, the package manager (often apt) makes contact with the package repositories listed in the /etc/apt/sources.list file and obtains details about the packages and their versions. It searches for new packages or updates that have become available since the last update.

3.
apt install wget
The apt install command is used in Debian-based Linux distributions, such as Ubuntu, to install software packages from the configured repositories. In this case, you want to install the wget package, which is a command-line tool for downloading files from the web.

4.
mkdir
The mkdir command is used in Linux to create directories (also known as folders). It allows you to create one or more directories (dir1 dir2 dir3 etc.) at a specified location within the file system.

Their is need for appropriate permissions to create directories in specific locations. If you encounter a permission denied error, consider running the mkdir command with root privileges using sudo if necessary.

5.
cd
The cd command in Linux is used to switch from the current working directory to previous in the terminal. It allows you to navigate the file system and switch to a different directory. To navigate into the previous directory you were in, you can use the command cd -

The fundamental tool to navigate the terminal's file system is the cd command. You can access files, navigate directories, and run commands from various locations.

6.
touch

The touch command in Linux is used to create empty files or update the timestamps (access time and modification time) of existing files. It is a versatile command that is often used to quickly create new files or update timestamps. To create a empty file use touch

If you want to create multiple files at once, you can provide a space-separated list of file names use touch "file1.txt", "file2.txt", and "file3.txt".

After running the touch command, the specified file(s) will be created. You can verify the creation or modification of the file(s) using other commands such as ls or stat.

7.
ls
The ls command is used in Linux to list the contents of a directory. It allows you to view the files and directories within the specified directory.

The ls command provides various options to modify its behavior. Here are a few commonly used options:

'-l' (long format): Displays detailed information about files, including permissions, ownership, size, and timestamps.
'-a' (all files): Shows all files, including hidden files that start with a dot (.).
'-h' (human-readable): Displays file sizes in a human-readable format, such as kilobytes or megabytes.
'-r' (reverse order): Lists files and directories in reverse order.

8.
sudo rm
The sudo rm command is used in Linux to delete files or directories with root privileges. "sudo" is used to execute the command as the superuser or root, and "rm" stands for "remove."

Note to use sudo_carefully, as it grants elevated privileges, including the ability to delete important system files. Verify your actions and ensure that you are deleting the intended files or directories.
To check if the action has been successfully executed, the Linux command _lS is used.

9.
mv

To move a file from one directory to another directory

Follow the steps below;

Create the second directory with the same command mkdir

Supply both the file's name and the destination folder's name when using the "mv" command to move a file.
Use the command mv /
To confirm if the file have been moved into the second created directory, navigate into the second directory using cd and Input the command "ls" to view the moved file.

10.
pwd
pwd Linux command stands for "Print Working Directory." It is a simple command that allows you to display the current working directory, which is the directory you are currently located in within the file system.
To use the pwd command, type the command in the terminal.

This output will vary depending on where you are in the file system. It helps you quickly identify your current location so you can navigate or work with files and directories effectively.

11.
cd ..
The cd command represents "Change Directory," why the .. stands for the parent directory. To change to the parent directory.

Open your terminal or command prompt.
Type the following command: cd .. and press the Enter key.

The parent directory of your current working directory will be reached with this command. For example, if your current directory is /home/username1/docs, running cd .. will take you to /home/username1/.

Capture the Image of a VM, Save in Azure Compute Gallery and Create a VMSS

Gbadamosi Tajudeen — Sun, 25 Jun 2023 10:52:33 +0000

In Azure, the "Capture" button is used to capture and generalize a virtual machine (VM) in order to create a similar reusable image on series of VM. The main function of the "Capture" button in Azure is to create a VM image that can be used to deploy new instances of virtual machines.

Prerequisite
Sign in to the Azure portal using [www.azure.microsoft.com]
Select a VM form the existing VM in the Azure resource list or create a new VM or attach a VM to the already created compute gallery.

To capture the image of a VM

Click to open the created VM, on the Azure service home page resource list.

Deallocate the VM: Before capturing the image, it is recommended to deallocate the VM to ensure a clean state.
To deallocate, Select the VM and click on the "Stop" button to deallocate it. Wait until the VM is in the "Stopped (Deallocated)" state.

Click on the "Capture" button in the toolbar at the top. This will open the "Capture virtual machine" blade.

To create the VM image

Provide the following details:
Image resource group: Choose an existing resource group or create a new one to hold the captured image.
Image region: Select the Azure region where you want to store the captured image.

Target azure compute gallery: Choose an existing compute gallery or create a new one to store the captured image.
Image OS state: Select the Azure operating system state (Generalized or Specialized)
Target VM image definition: click on create new and enter a unique VM image definition name for the captured image
Click on Ok button

Enter the version number and click Review and Create

Click Create and wait for the deployment to be completed.

Click the Go to resource to view the VM image definition overview

Differences Between Generalized and Specialized Image

Generalized Image:
A generalized image is represented by a clean and generic template that does not contain any VM-specific configurations or data. It serves as a base image for creating new VM instances. Visually, you can imagine a generalized image as a blank slate or a template without any specific details tied to a particular VM instance. It represents a clean starting point for deploying multiple VMs with consistent configurations.
A generalized image is meant to serve as a simple, repeatable template for building new virtual machine instances.
A VM goes through a process known as generalization in which all VM-specific settings, configuration, and data are eliminated. This procedure detaches the VM from the original VM instance and makes it ready to be used as a base image. No machine-specific configurations, such as hostname, user accounts, or network settings, are present in a generalized image. These settings are anticipated to be used for creating new virtual machine instances based on the generalized image.

Specialized Image
A specialized image represents a customized and specific VM instance, including all the configurations, settings, and software installations that were present in the original VM. Visually, a specialized image can be imagined as a snapshot or a copy of the original VM, preserving its specific configurations. It captures the state of a VM at a particular point in time, including any modifications made to the VM during its usage.
A specialized image is made especially for a certain VM instance.
All of the parameters, settings, and installed applications from the original VM instance are included in a specialized image.
When you wish to save and reuse a virtual machine with a specific configuration or software installation, specialized images might be helpful. They are frequently used to build backups, move VMs between subscriptions, or record a VM state for future usage or recovery.
Specialized images are frequently bound to the original virtual machine instance and may not be readily distributed on multiple virtual machines without risking conflicts or inconsistencies.

Procedure to create an Azure Compute Gallery

Gbadamosi Tajudeen — Sat, 24 Jun 2023 05:30:49 +0000

A Compute Gallery, also known as gallery images or image definitions, is a service Azure provides that enables you to build and manage a collection of virtual machine (VM) images. It offers a central location to store, arrange, and distribute customized VM images, making deploying standardized and pre-configured virtual machines simpler. By creating standardized images with pre-configured settings, apps, and customizations using Compute Galleries, you can simplify VM deployments. This makes the process of creating new virtual machines (VMs) easier, ensures consistency across deployments, and makes it easier for teams and organizations to share images.

A Compute Gallery consists of the following key components:

Image Definitions: A VM image definition designates a particular version of the picture. It contains information like the publisher, SKU, and version number. To create new VM instances, image definitions act as templates.
Shared Image Gallery, Image Versioning: Allow to capture updates and changes to new version of image over time.
Replication: the option help to replicate images across multiple Azure regions within a Compute Gallery. Replication helps enhance availability and reduces latency by making images available closer to the Azure regions where you need to deploy virtual machines.
Access Control and Sharing: Compute Galleries provide access control mechanisms to manage who can view, create, and use the images within the gallery. You can define fine-grained permissions to allow or restrict access to specific users or Azure Active Directory (AAD) groups.

Change Tier: Hot, Cool and Archive

Azure offers three storage tiers: Hot, Cool, and Archive. To assist organization in managing their data storage based on various usage patterns and financial considerations, Here is a quick breakdown of each tier:

Hot: Azure's "Hot" tier is created for frequently accessed data that demands quick access and high-performance storage. Although it costs higher than other levels, it has the best availability and shortest access times. Active databases, real-time analytics, and regularly viewed files are examples of the types of data that are appropriate for the Hot tier and are necessary for day-to-day operations.

Cool: The "Cool" tier is intended for less frequently used data but nonetheless needs rapid access when needed. Compared to the Hot tier, it offers a more affordable storage alternative. Backups, archive data, disaster recovery data, and files that are rarely used but yet need quick access times should all be stored in the Cool tier.

The "Archive" tier of Azure's storage is the least expensive option and is intended for long-term storage of data that is infrequently accessed but must be kept for compliance or regulatory purposes. The Archive layer has a retrieval time delay but has the lowest storage cost. It is perfect for keeping historical data, records required by regulations, and other information that must be kept for a long period but is not likely to be often accessed.

In conclusion, Organizations may reduce storage costs while ensuring the appropriate degree of speed and availability for their data depending on usage patterns and retention needs by employing Azure's Hot, Cool, and Archive storage tiers. Depending on changing demands, Azure offers the freedom to transfer data across various tiers with ease, enabling effective data management and cost reduction.
