Linux is an embedded system and a widely used system software. Its characteristics are: 1. The Linux system is completely open and free; 2. The significant advantage of the Linux operating system is that it is multi-user and multi-purpose. Tasks ensure that multiple users do not affect each other; 3. The device is independent. As long as the driver is installed, any user can use and operate any device.
The operating system of this tutorial: linux5.18.14 system, DELL G3 computer.
Linux is an embedded system.
The biggest feature of Linux is that the source code is open and follows the GPL agreement; it can run on handheld computers, set-top boxes or game consoles; it can run on a variety of hardware platforms, such as x86, 680x0, SPARC, Alpha and other processor platforms.
Embedded Operating System (Embedded Operating System, referred to as: EOS) refers to the operating system used for embedded systems. The embedded operating system is a widely used system software, which usually includes hardware-related underlying driver software, system kernel, device driver interface, communication protocol, graphical interface, standardized browser, etc.
The embedded operating system is responsible for the allocation of all software and hardware resources, task scheduling, control and coordination of concurrent activities of the embedded system. It must embody the characteristics of the system in which it is located, and be able to achieve the functions required by the system by loading and unloading certain modules.
The operating systems currently widely used in the embedded field include: embedded real-time operating system µC/OS-II, embedded Linux, Windows Embedded, VxWorks, etc., as well as Android, iOS etc.
Embedded Linux
A system that makes appropriate modifications and deletions to Linux and can be used on embedded systems is the embedded Linux operating system. It has the following characteristics:
Linux system is completely open and free. It is the openness that enables it to be compatible with other systems and thereby realize the interconnection of information. And it can modify the source code arbitrarily, which is not available in other systems.
The significant advantages of the Linux operating system are multi-user and multi-tasking. It ensures that multiple users do not interfere with each other; after multi-tasking is started independently, they do not interfere with each other, greatly improving efficiency and giving full play to performance.
Devices are independent. As long as the driver is installed, with the support and help of the driver, any user can use and operate any device just like using files, which eliminates the need for people to consider the specific form of the device.

Linux: How to Enter Recovery Mode (and Maintenance)Apr 18, 2025 am 12:05 AMThe steps to enter Linux recovery mode are: 1. Restart the system and press the specific key to enter the GRUB menu; 2. Select the option with (recoverymode); 3. Select the operation in the recovery mode menu, such as fsck or root. Recovery mode allows you to start the system in single-user mode, perform file system checks and repairs, edit configuration files, and other operations to help solve system problems.
Linux's Essential Components: Explained for BeginnersApr 17, 2025 am 12:08 AMThe core components of Linux include the kernel, file system, shell and common tools. 1. The kernel manages hardware resources and provides basic services. 2. The file system organizes and stores data. 3. Shell is the interface for users to interact with the system. 4. Common tools help complete daily tasks.
Linux: A Look at Its Fundamental StructureApr 16, 2025 am 12:01 AMThe basic structure of Linux includes the kernel, file system, and shell. 1) Kernel management hardware resources and use uname-r to view the version. 2) The EXT4 file system supports large files and logs and is created using mkfs.ext4. 3) Shell provides command line interaction such as Bash, and lists files using ls-l.
Linux Operations: System Administration and MaintenanceApr 15, 2025 am 12:10 AMThe key steps in Linux system management and maintenance include: 1) Master the basic knowledge, such as file system structure and user management; 2) Carry out system monitoring and resource management, use top, htop and other tools; 3) Use system logs to troubleshoot, use journalctl and other tools; 4) Write automated scripts and task scheduling, use cron tools; 5) implement security management and protection, configure firewalls through iptables; 6) Carry out performance optimization and best practices, adjust kernel parameters and develop good habits.
Understanding Linux's Maintenance Mode: The EssentialsApr 14, 2025 am 12:04 AMLinux maintenance mode is entered by adding init=/bin/bash or single parameters at startup. 1. Enter maintenance mode: Edit the GRUB menu and add startup parameters. 2. Remount the file system to read and write mode: mount-oremount,rw/. 3. Repair the file system: Use the fsck command, such as fsck/dev/sda1. 4. Back up the data and operate with caution to avoid data loss.
How Debian improves Hadoop data processing speedApr 13, 2025 am 11:54 AMThis article discusses how to improve Hadoop data processing efficiency on Debian systems. Optimization strategies cover hardware upgrades, operating system parameter adjustments, Hadoop configuration modifications, and the use of efficient algorithms and tools. 1. Hardware resource strengthening ensures that all nodes have consistent hardware configurations, especially paying attention to CPU, memory and network equipment performance. Choosing high-performance hardware components is essential to improve overall processing speed. 2. Operating system tunes file descriptors and network connections: Modify the /etc/security/limits.conf file to increase the upper limit of file descriptors and network connections allowed to be opened at the same time by the system. JVM parameter adjustment: Adjust in hadoop-env.sh file
How to learn Debian syslogApr 13, 2025 am 11:51 AMThis guide will guide you to learn how to use Syslog in Debian systems. Syslog is a key service in Linux systems for logging system and application log messages. It helps administrators monitor and analyze system activity to quickly identify and resolve problems. 1. Basic knowledge of Syslog The core functions of Syslog include: centrally collecting and managing log messages; supporting multiple log output formats and target locations (such as files or networks); providing real-time log viewing and filtering functions. 2. Install and configure Syslog (using Rsyslog) The Debian system uses Rsyslog by default. You can install it with the following command: sudoaptupdatesud
How to choose Hadoop version in DebianApr 13, 2025 am 11:48 AMWhen choosing a Hadoop version suitable for Debian system, the following key factors need to be considered: 1. Stability and long-term support: For users who pursue stability and security, it is recommended to choose a Debian stable version, such as Debian11 (Bullseye). This version has been fully tested and has a support cycle of up to five years, which can ensure the stable operation of the system. 2. Package update speed: If you need to use the latest Hadoop features and features, you can consider Debian's unstable version (Sid). However, it should be noted that unstable versions may have compatibility issues and stability risks. 3. Community support and resources: Debian has huge community support, which can provide rich documentation and
