What is amazon linux?

Amazon Linux is a distribution powered and updated by Amazon Web Services that can be used with Elastic Compute Cloud (EC2) instances.

Integrated and extensible:

The Amazon Linux AMI is packaged and configured to provide tight integration with Amazon Web Services, many AWS APIs Tools and CloudInit are preinstalled. On startup, CloudInit allows remote provisioning of Amazon EC2 instances by passing instance configuration operations to the instance via EC2 user data fields.

Security Configuration:

Amazon Linux AMI configuration enhances security by focusing on two main security goals, one is to restrict access and the other is to reduce software vulnerabilities. Amazon Linux AMI limits remote access functionality by using an SSH key pair and disabling remote root login. In addition, Amazon Linux AMIs reduce the number of non-critical software packages installed on the instance, limiting the risk of potential security vulnerabilities. Security updates rated Critical or Important are automatically applied on the initial startup of the AMI.

Package Repository Access:

The Amazon Linux AMI is designed to be used with online package repositories hosted in various Amazon EC2 regions . Hosting repositories in each region helps deploy updates quickly without incurring any data transfer charges.

Related Extensions:

Amazon Linux 2023 is optimized for Amazon EC2, deeply integrated with the latest AWS features, and provides an integrated experience with many AWS-specific tools.

In terms of security, Amazon said Amazon Linux 2023 comes with preconfigured security policies to help users set up the system to meet various common industry guidelines. Amazon Linux 2023 also comes with a hardened Linux kernel by default for added security.

In terms of lifecycle support, Amazon will release a new major version of Amazon Linux every two years, including significant changes to the kernel, toolchain, GLib C, OpenSSL, and other system libraries and utilities. In addition to this, security updates will be available when they are ready, and there will be quarterly updates that include security updates, bug fixes, and new features and packages. These quarterly updates will update things like language runtimes and popular software packages.

Each version of Amazon Linux will be supported for five years, but after the initial two years and subsequent releases, a version will enter a maintenance phase and will only receive security vulnerability fixes and patches. Ideal for users who don't want to keep upgrading their operating system.

The Building Blocks of Linux: Key Components ExplainedApr 30, 2025 am 12:26 AM

The core components of the Linux system include the kernel, file system, and user space. 1. The kernel manages hardware resources and provides basic services. 2. The file system is responsible for data storage and organization. 3. Run user programs and services in the user space.

Using Maintenance Mode: Troubleshooting and Repairing LinuxApr 29, 2025 am 12:28 AM

Maintenance mode is a special operating level entered in Linux systems through single-user mode or rescue mode, and is used for system maintenance and repair. 1. Enter maintenance mode and use the command "sudosystemctlisolaterscue.target". 2. In maintenance mode, you can check and repair the file system and use the command "fsck/dev/sda1". 3. Advanced usage includes resetting the root user password, mounting the file system in read and write mode and editing the password file.

Linux Maintenance Mode: Understanding the PurposeApr 28, 2025 am 12:01 AM

Maintenance mode is used for system maintenance and repair, allowing administrators to work in a simplified environment. 1. System Repair: Repair corrupt file system and boot loader. 2. Password reset: reset the root user password. 3. Package management: Install, update or delete software packages. By modifying the GRUB configuration or entering maintenance mode with specific keys, you can safely exit after performing maintenance tasks.

Linux Operations: Networking and Network ConfigurationApr 27, 2025 am 12:09 AM

Linux network configuration can be completed through the following steps: 1. Configure the network interface, use the ip command to temporarily set or edit the configuration file persistence settings. 2. Set up a static IP, suitable for devices that require a fixed IP. 3. Manage the firewall and use the iptables or firewalld tools to control network traffic.

Maintenance Mode in Linux: A System Administrator's GuideApr 26, 2025 am 12:20 AM

Maintenance mode plays a key role in Linux system management, helping to repair, upgrade and configuration changes. 1. Enter maintenance mode. You can select it through the GRUB menu or use the command "sudosystemctlisolaterscue.target". 2. In maintenance mode, you can perform file system repair and system update operations. 3. Advanced usage includes tasks such as resetting the root password. 4. Common errors such as not being able to enter maintenance mode or mount the file system, can be fixed by checking the GRUB configuration and using the fsck command.

Maintenance Mode in Linux: When and Why to Use ItApr 25, 2025 am 12:15 AM

The timing and reasons for using Linux maintenance mode: 1) When the system starts up, 2) When performing major system updates or upgrades, 3) When performing file system maintenance. Maintenance mode provides a safe and controlled environment, ensuring operational safety and efficiency, reducing impact on users, and enhancing system security.

Linux: Essential Commands and OperationsApr 24, 2025 am 12:20 AM

Indispensable commands in Linux include: 1.ls: list directory contents; 2.cd: change working directory; 3.mkdir: create a new directory; 4.rm: delete file or directory; 5.cp: copy file or directory; 6.mv: move or rename file or directory. These commands help users manage files and systems efficiently by interacting with the kernel.

Linux Operations: Managing Files, Directories, and PermissionsApr 23, 2025 am 12:19 AM

In Linux, file and directory management uses ls, cd, mkdir, rm, cp, mv commands, and permission management uses chmod, chown, and chgrp commands. 1. File and directory management commands such as ls-l list detailed information, mkdir-p recursively create directories. 2. Permission management commands such as chmod755file set file permissions, chownuserfile changes file owner, and chgrpgroupfile changes file group. These commands are based on file system structure and user and group systems, and operate and control through system calls and metadata.
