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 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.

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.

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.

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.

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.
