Operation and MaintenanceLinux Operation and MaintenanceDetermine whether linux is 64-bit or 32-bit
Method 1:
getconf LONG_BIT
Enter the getconf LONG_BIT command in the Linux terminal. If it is a 32-bit machine, the result will be 32.
For example:
[root@localhost ~]# getconf LONG_BIT 32
If it is a 64-bit machine, the result is 64.
[root@localhost ~]# getconf LONG_BIT 64
Method 2:
uname -a
If it is a 64-bit machine, x86_64 will be output.
[chenzhou@testweb01 ~]$ uname -a Linux testweb01 2.6.18-308.4.1.el5 #1 SMP Tue Apr 17 17:08:00 EDT 2012 x86_64 x86_64 x86_64 GNU/Linux
You can see that x86_64 is output in the execution result of uname-a, indicating that the machine is 64-bit, otherwise it means that the machine is 32-bit.
[root@localhost ~]# uname -a Linux localhost.localdomain 2.6.18-164.el5 #1 SMP Tue Aug 18 15:51:54 EDT 2009 i686 i686 i386 GNU/Linux

Linux: A Deep Dive into Its Fundamental PartsApr 21, 2025 am 12:03 AMThe 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.
Linux Architecture: Unveiling the 5 Basic ComponentsApr 20, 2025 am 12:04 AMThe 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 Operations: Utilizing the Maintenance ModeApr 19, 2025 am 12:08 AMLinux 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.
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.

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),
