What is the Linux file system structure explained?
The Linux file system starts with the root directory (/) and uses a unified tree structure to organize files. 1. The root directory/ is the starting point of all files, integrating all hard disk and partition content; 2./home stores user personal files, which are protected by default; 3./etc is used to store system and application configuration files; 4./usr contains system programs such as command tools, library files; 5./var stores logs, caches and other variable data; 6./dev contains device files, representing hardware devices; 7./proc and/sys provide real-time information on the kernel and hardware. Understanding these directories helps quickly locate problems, manage services, and write scripts, which are complex at first but are easy to master after actual use.

No wifi after installing linux
After installing Linux, you can't connect to Wi-Fi, and follow the following steps to solve it: 1. Check whether the wireless is disabled, use the rfkill command to view and unlock it; 2. Confirm whether the network card driver is installed, check the device through lspci or iplink and install the corresponding driver; 3. Check whether the NetworkManager is running normally, restart the service or use command line tools to connect if necessary; 4. Troubleshoot the conflict between BIOS settings, hardware switches or dual systems, turn off Windows Quick Start or adjust the BIOS settings. Most of the problems are caused by the driver not being installed or the wireless is disabled, so you can solve it by checking it in order.

How to find the parent process ID (PPID) of a process?
To check the parent process ID (PPID) of the process, the method varies from system to system. ① In Unix-like systems, you can use the ps command to query the PPID of the specified PID with the -o parameter, such as ps-oppid=-p; if the process name is unknown, use ps-ef|grep to view the third column PPID; ② By reading the /proc//status file, use cat/proc//status|grepPPid to obtain more stable information; ③ PowerShell can use Get-WmiObject to query the ParentProcessId field, or add the "parent process ID" column to display through the task manager; ④ In terms of programming, in C/

What is the difference between df and du commands?
df displays the overall usage of the disk, providing an overview of used and available space; du counts the space usage of specific directories and files. 1.df is used to view the total space, used, remaining and usage percentage of each mounted file system, which is suitable for understanding the overall storage status of the system. 2.du goes deep into the directory structure, helps locate specific files or subdirectories that occupy space, and often simplifies output with options such as -sh. 3. The results of the two may differ due to different processing methods of deleted but not released files, hidden metadata or mount points. Tools such as lsof need to be used to troubleshoot abnormal space occupation.

What is a container and how does it differ from a virtual machine?
The core difference between containers and virtual machines (VMs) is the isolation method and resource usage. 1. The container shares the host system kernel, and achieves process isolation through namespace and cgroups, and is lightweight and fast-start, suitable for microservices and cloud-native applications; 2. The virtual machine simulates a complete computer, including an independent operating system, providing stronger isolation but consumes a lot of resources, suitable for running legacy systems or multi-operating system environments; 3. In actual use, containers, VMs or combinations can be selected according to needs to take into account performance and security.

What is Ansible and what are its main components (playbook, inventory, role)?

The Inventory file is used to define hosts and host groups managed by Ansible. It can specify variables, IP ranges, nested groups, and supports dynamic acquisition of host lists. Role is a reusable unit that organizes tasks, templates, files and variables. It has a standard directory structure to improve code reusability and collaboration efficiency. When using it, specify the target host through inventory, define the operation task through playbook, and use r
