Checking method: 1. Use the "cat /etc/os-release" command to check the system version in the "name" item in the output list; 2. Use the "cat /proc/version" command to check the system version in the "name" item in the output list. Check the system version in the output information; 3. Use the "dmesg | grep "linux"" command.
#The operating environment of this tutorial: Red Hat Enterprise Linux 7.3 system, Dell G3 computer.
For mainstream distribution versions such as rhel, debian, opensuse, and archlinux, they each have different package managers to manage software packages on the system. If you don't know which distribution system you are using, you will have no idea where to start when installing the software package.
The following article will share with you some methods of checking the Linux distribution system.
Method 1: Use cat /etc/os-release command
rhel system cat /etc/os-release cat / etc/system-release cat /etc/redhat-release centos system cat /etc/centos-release fedora system
Method 2: cat /proc/version
The /proc/version file records the version of the Linux kernel released, the gcc version used to compile the kernel, the time of kernel compilation, and the user name of the kernel compiler
Method 3: dmesg command
dmesg (display message or driver message) is a command on most unix operating systems, used to print kernel message buffer information

The core components of Linux include kernel, file system, shell, user and kernel space, device drivers, and performance optimization and best practices. 1) The kernel is the core of the system, managing hardware, memory and processes. 2) The file system organizes data and supports multiple types such as ext4, Btrfs and XFS. 3) Shell is the command center for users to interact with the system and supports scripting. 4) Separate user space from kernel space to ensure system stability. 5) The device driver connects the hardware to the operating system. 6) Performance optimization includes tuning system configuration and following best practices.

The five basic components of the Linux system are: 1. Kernel, 2. System library, 3. System utilities, 4. Graphical user interface, 5. Applications. The kernel manages hardware resources, the system library provides precompiled functions, system utilities are used for system management, the GUI provides visual interaction, and applications use these components to implement functions.

Linux maintenance mode can be entered through the GRUB menu. The specific steps are: 1) Select the kernel in the GRUB menu and press 'e' to edit, 2) Add 'single' or '1' at the end of the 'linux' line, 3) Press Ctrl X to start. Maintenance mode provides a secure environment for tasks such as system repair, password reset and system upgrade.

The 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.

The 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.

The 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.

The 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.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),

DVWA
Damn Vulnerable Web App (DVWA) is a PHP/MySQL web application that is very vulnerable. Its main goals are to be an aid for security professionals to test their skills and tools in a legal environment, to help web developers better understand the process of securing web applications, and to help teachers/students teach/learn in a classroom environment Web application security. The goal of DVWA is to practice some of the most common web vulnerabilities through a simple and straightforward interface, with varying degrees of difficulty. Please note that this software
