As we all know, Linux is a Unix-like operating system that is free to use and spread freely. It is a multi-user, multi-task, multi-threading and multi-CPU operating system based on POSIX and UNIX. It can run major UNIX software tools, applications and network protocols. Today we will take a look at what Linux is mainly used for.
Most companies will not use Linux as a desktop operating system. Linux is mainly used for back-end server operating systems. Many facts have proven that Linux can fully undertake critical tasks. Computing applications, and there are many Linux systems that have never been down since they started running.
Linux system mainly occupies the server market. Where Linux systems are usually used:
1. Linux control
Linux is more free. I can write a piece of my own script code to use according to my own needs. When executing the program, I only need to set You can open it by setting your own shortcut key. Under Linux, almost all software is open source, and everyone can modify it for their own use, even Linux itself.
2. Personal entertainment or office
Linux distribution Ubuntu, because this operating system is relatively friendly to many individual users. It does not require too many settings or writing any complicated code. It is enough for personal entertainment.
3. Government enterprises and other departments use operating systems internally for confidentiality reasons.
With the exposure of the Prism Gate, governments and enterprises around the world are paying more and more attention to network security issues. The security issues of Windows have also revealed increasingly obvious shortcomings, while high security and stability The powerful Linux system has become the preferred government office operating system in various countries and is purchased in large quantities.

The core components of the Linux system include the kernel, file system, and user space. 1. The kernel manages hardware resources and provides basic services. 2. The file system is responsible for data storage and organization. 3. Run user programs and services in the user space.

Maintenance mode is a special operating level entered in Linux systems through single-user mode or rescue mode, and is used for system maintenance and repair. 1. Enter maintenance mode and use the command "sudosystemctlisolaterscue.target". 2. In maintenance mode, you can check and repair the file system and use the command "fsck/dev/sda1". 3. Advanced usage includes resetting the root user password, mounting the file system in read and write mode and editing the password file.

Maintenance mode is used for system maintenance and repair, allowing administrators to work in a simplified environment. 1. System Repair: Repair corrupt file system and boot loader. 2. Password reset: reset the root user password. 3. Package management: Install, update or delete software packages. By modifying the GRUB configuration or entering maintenance mode with specific keys, you can safely exit after performing maintenance tasks.

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.
