- Master teaches you how to install and use Docker on Linux
- Containers allow you to scale delivery capabilities (both internally and externally) in ways never possible before. For example, you can quickly deploy multiple NGINX instances (even for multiple different stages - such as development and production). Unlike virtual machines, containers do not consume too many system resources. Docker makes it extremely easy to create, deploy, and manage containers. Even better, installing and using Docker is particularly convenient on the Linux platform. I will show you how easy it is to install Docker on Linux and get you started with Docker. My demonstration platform is Ubuntu16.04Server, but the process is similar on most other Linux platforms. I'm assuming you

- What are the best Linux distributions for programming? This article evaluates them and provides some perspective here. In short, the purpose is to help find one that suits your style. What are Linux distributions? A Linux distribution is a complete and packaged operating system based on the Linux kernel. But what is the Linux kernel? good question! This is the core of the operating system, as it interacts directly with the computer's hardware and manages system resources. However, the Linux kernel alone is not enough for most users, as it lacks many software applications and tools required for daily estimation tasks. A Linux distribution consists of the Linux kernel and a series of libraries, software packages, system utilities and graphical interfaces that make it

- Teach you how to change the font on the Linux console
- I try to keep my mind as peaceful as possible, but there are always some things that throw me off, like the console font being too small. Mark my words, friend, one day your eyes will degenerate and you will no longer be able to see those tiny fonts you use when coding, and then you will regret it. Luckily, Linux diehards, you can change the console font. According to the consistent nature of Linux, the ever-changing Linux environment makes this problem less simple and clear, and there is no such thing as font management on Linux, which makes us easily confused. In this article, I'm going to show you the easiest way I've found to change fonts. What the hell is a Linux console? First let’s clarify what exactly we are talking about. When I

- Analysis of common permission maintenance backdoor technologies under Linux
- Obtaining the target's permissions during the penetration process is just the beginning. Usually, a side door is left for easy access again (APT for short). Therefore, it is necessary to maintain permissions and hide the side door. This article will analyze the common permission maintenance side door technologies under Linux, so that you can fight against them if you know them. 1. Principle of adding root account: lower the root password to password for the root user useradd-u-0-o-groot-Groot:password|chpasswd. The above command may not be added. If it cannot be added, execute the two commands separately useradd- u0-o-groot-Grootrootechoroot:root|chpasswdIf it still fails p

- Linux performance monitoring
- This article mainly talks about the operation of performance monitoring on Linux (CentOS). 1. Monitor cpu usage --uptime. This command will print out how long the system has been running at the current time. The current number of logged-in users and the average load of the system. The load here is the number of processes in the CPU waiting queue per unit time. Waiting The more processes there are, the busier the CPU is. 2. Monitor the usage of memory and swap partition - free 3. System disk usage - df Here we use df-h to display capacity information in a user-friendly manner 4.

- The regular directory structure of the Linux system, no matter what version of directory you switch between
- After we install the Linux system, the Linux system will also manually generate many files and directories like the Windows system. Such directories all contain different meanings. Next, let’s introduce what this kind of directory represents? Also, what are the distribution versions of the Linux operating system in the command line interface, and how do we switch between different directories. 1. Linux system directory structure. What we introduce here is the regular directory structure of the Linux system.

- linux htop An in-depth understanding of the top command under Linux: performance analysis tools and common options
- 1. top command 1. Introduction The top command is a commonly used performance analysis tool under Linux. It can display the resource usage of each process in the system in real time, similar to the Windows Task Manager. top is a dynamic display process, that is, the current status can be continuously refreshed through the user's keyboard. If this command is executed in the foreground, it will occupy the foreground exclusively until the user terminates the program. To be more precise, the top command provides real-time control of the system. Processor status monitoring. It will display a list of the most "sensitive" tasks for the CPU in the system. This command can sort tasks by CPU usage, video memory usage and execution time; and many features of this command can be accessed through interactive commands or Then set it in the personal customization file. 2,

- Use Linux find command with caution
- When using the find command under Linux, use the -ok option to avoid accidental deletion of files. This option will ask for your permission before removing any files. Recently, a friend reminded me that there is a useful option to run the find command more cautiously, which is -ok. It works similarly to -exec, except for one important difference, which causes the find command to request permission before performing the specified operation. Here's an example. If you use the find command to find files and delete them, you may use the following command: $find.-namerunme-execrm{}\; Any file named "runme" in the current directory and its subdirectories will be deleted immediately—

- Do you know several techniques to solve the problem of Linux space not being released?
- In the Linux system, the Linux command chm, when the user installs, uninstalls, or adds a program, the system space may be weakened. The following are some of my methods to solve the problem of Linux space not being released: 1. Disk space detection. The reason why the space is not released may be because the C drive space is not enough for Linux certification, so we should use the df-h command to check the remaining space of the C drive. Such as: $df-hFilesystemSizeUsedAvailUse%Mountedonudev7.8G07.8G0%/devtmpfs1.6G9.5M1.6G1%/run/dev/mapper/ubuntu-vg925G287G639G31%
