- Explore benchmarking tools under Linux: a powerful tool for evaluating hardware and software performance
- Benchmarking is the act of running a computer program to evaluate the performance of hardware and software. Basic hardware testing includes evaluating the performance of different components such as processors, video memory, motherboards, hard drives, and networks. There are two categories of benchmarks: composite and applied. Composite benchmarks perform stress tests on a piece of hardware, such as continuously writing and reading data. Application benchmarks judge the performance of real-world applications such as databases and servers. Benchmark testing software allows system testers and users to objectively and independently evaluate hardware performance. There are many excellent open source Linux benchmark testing tools under Linux, such as PhoronixTestSuite, IOzone, netperf, etc. PhoronixTestSuite is a well-known website in the industry. It often

- Two methods and risk control for installing Linux dual systems under windows
- There are two ways to install Linux dual system under window: 1. U disk installation (the method I used, explained earlier) 2. EasyBCD tool installation (detailed tutorial on using EasyBCD to implement Windows 7 and Linux dual systems) Use U disk win10 to install centos7 dual system System, there are many articles on the Internet, I won’t list them one by one, but this does not save me from taking detours. I don’t know whether it is due to historical legacy or the system itself. Things that were very simple at first have made netizens say that they are very complicated. . There is the biggest risk point here: Linux covers the window system. Control this risk, and even if you don’t succeed once, you can try it again. Let’s talk about a few big steps: 1.

- How to operate Linux proficiently? Learning the directory file operation command cd is the key
- Click "Linux Commune" under the title above to quickly follow the explanation of Linux common directory file operation commands.

First of all, what we need to learn is Linux directory file operation command cd switches the user's current working directory cd (options) (parameters) The cd command is used to switch the user's working directory to a specified directory. You can use an absolute path or a relative path for this specified directory. (The absolute path means starting from the root directory, and the relative path means starting from the current directory) If you use the cd command directly without adding any parameters, it will switch to the home directory of the logged in user.

- Amazon Cloud sets up a server for free to create your instance
- As a developer, I have always hoped to have my own server to deploy applications. I have been interested in Alibaba Cloud/Tencent Cloud for a long time, but the trial period of both is not long. Alibaba’s is up to 30 days, and Tencent’s is longer. It is only 7 days. I have put it aside because I have no special needs. I heard that Amazon Cloud has a one-year free trial, but I was worried that the overseas server might be inconvenient, so I didn’t try it. Recently, on a boring afternoon, I finally decided to try it. After trying it out, I found it quite convenient after playing around with two of them. Now I will summarize my experience of stepping into the pit and share it with you. It is very generous to create a free EC2 instance account on AWS and apply for free qualifications of Amazon Cloud (AWS for short). As long as you are new Users who apply can get a one-year free trial qualification

- An in-depth interpretation of the plus sign and dot in the permission column in Linux
- 1. Overview In Linux, the ls-l command is the most commonly used. The first column in the command display result is also where we are more concerned. Generally speaking, the characters indicating permissions occupy 10 positions. However, we often see content displayed at the eleventh position in this column. The most common one is the dot (.), and the plus sign (+) will also appear in this position. What is this? What's going on? Let's try it out with our own hands, shall we? 2. Regarding the dot (.) in the permission column 2.1 Let us take a look at the root directory. [root@DCGH~]#ls-lZ/lrwxrwxrwx.rootrootsystem_u:object_r:bin_t:s0bin->

- How to configure security groups for cloud hosts in batches in Python?
- The biggest change for operation and maintenance personnel in recent years may be the emergence of the public cloud. I believe that many small partners may run their business on the public cloud. Because of the company's business relationship, I personally came into contact with the public cloud very early, probably I started using Amazon Cloud around 2012, and later gradually came into contact with domestic Alibaba, Tencent Cloud, etc. As the company's business developed domestically, we have also used many domestic public cloud vendors in the past few years, so in terms of cloud operation and maintenance I have also accumulated some experience, from traditional physical machines to public cloud operation and maintenance. I personally think that the biggest question is whether you can think in terms of public cloud to achieve a safe, stable, scalable and economical business architecture. Cloud operation and maintenance is different from traditional operation and maintenance. For example, anyone who understands public cloud knows the concept of security group.
