An in-depth analysis of CentOS's default file system
CentOS operating system is an open source Linux distribution that is widely used in server environments. When installing the CentOS operating system, there are many choices for common file systems. Among them, the most commonly used file system is ext4. This article will introduce in detail the characteristics and advantages of CentOS default file system ext4.
First of all, ext4 is a common file system on Linux and is an upgrade from the previous version ext3. Compared with ext3, the ext4 file system has improved performance, reliability and functionality. In CentOS, ext4 is often considered the default file system choice because it is considered the best balance of performance and stability.
The ext4 file system supports larger file and partition sizes, up to 16TB files and 1EB partitions. This means that on CentOS systems, users can store more and larger files, which is suitable for scenarios that require large-scale data storage in server environments.
In addition, the ext4 file system also has higher performance. It supports higher concurrent file system operations, faster disk checks, and faster file writing speeds. This allows using the ext4 file system on CentOS systems to provide more stable and efficient data storage and access.
Another advantage of the ext4 file system is its greater fault tolerance. It has better logging capabilities and can quickly restore the file system in the event of an unexpected power outage or system crash, reducing the probability of data loss. This is critical for data protection in server environments, ensuring data security and integrity.
In the CentOS system, the ext4 file system is selected by default because of its compatibility and stability. As one of the mainstream file systems in Linux systems, ext4 is widely supported and used, and has good compatibility with various applications and tools. At the same time, after years of development and testing, the ext4 file system has high stability, can run stably for a long time, and is not prone to data loss or damage.
In short, in the CentOS system, the ext4 file system is selected by default due to considerations of performance, capacity, fault tolerance, and stability. As a powerful and widely used file system, ext4 performs well in server environments and can meet the needs of most users. Therefore, when installing the CentOS operating system, choosing the ext4 file system by default is a wise choice, which can provide users with a stable and reliable data storage and management environment.

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.

Linux 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.

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),
