Preface
As a bridge between hardware and software, I am most exposed to Windows and Centos. I still remember the original Linux private dish of Brother Niao , and Centos is about to stop maintenance and updates (Centos7 will be maintained until 2024), which has no impact on personal learning. Impact, but for enterprises, they need to consider alternatives to future server operating systems. This article discusses the causes and consequences of Centos becoming out of print and the learning and understanding of openEuler.
1. The causes and consequences of Linux distribution Centos becoming out of print
Reason for saving money: To make money
Specific explanation: Red Hat no longer supports the subsequent development of CentOS and launched CentOS Stream as an open source and free community version. However, one of the important reasons why many users choose Centos is that the version precipitated based on the stable commercial version is more stable (there is no commercial version Some new features but insignificant), now Centos Stream is not as stable as the commercial version (official statement: CentOS Stream is no longer suitable for use as an enterprise Linux operating system), users who are used to Centos can only pay the price, or upgrade to RHEL Business Edition, or choose another option.
Reflection on the incident: Due to its stable characteristics and use by many companies, CentOS has a large number of users and rich documentation in the country. It is the standard server OS of almost all Internet companies, including first-tier manufacturers such as BAT (big manufacturers according to their own Business development, small factories directly use). It cannot be said that using open source is a good thing. It is indeed wonderful at the beginning and is in line with the spirit of the open source community. But behind open source organizations are companies. When they make changes, their users will have to pay a huge price. CentOS 7 is currently supported until 2024. For many Internet companies, there is still a buffer time of at least 5-10 years. We hope that we can find our "CentOS" after that. Source of quotation for this paragraph: Zhihu
Quality operating system:
- RT-Thread (Internet of Things operating system with contributions from embedded engineers across the country)
- Kirin (won the bid for Kirin, U-Kirin, Galaxy Kirin and other Kirin to be used in operating systems for domestic units’ own use)
- openEuler (HarmonyOS is a mobile operating system, and oepnEuler is also an os supported by Huawei)
- Debian series
ubantu (suitable for development environment and novice learning)
kali (integrates many tools, understands everything)
Debian (suitable for server, requires certain skills)
- If you are a Linux expert, I recommend debian
- If you are an ordinary user (enthusiast), I recommend ubuntu
- For the choice of enterprise production server system, I personally recommend Debian
2. Learning and understanding openEuler
Last year, the school organized a practical openEuler open source internship. In addition to learning the operation of git and Linux distributions and the open source community and other related knowledge, I was also able to get a certificate and write it on my resume, which can be used to improve the word count, which is quite good. The papers given by the school can be used to offset the cost of purchasing the certification course and taking the exam, which doubles the happiness. I still remember that I participated in a Huawei Cloud event during the winter vacation and received a Huawei headset in the final draw. One of Huawei's partner companies came to the school to give a lecture and asked questions and also received a sports bracelet. Huazi was so generous! So boldly participate in the openEuler open source community
Introducing
the official website address of openEuler: https://openeuler.org/
openEuler is an open source, Linux kernel-based operating system (Centos-based Linux distribution)
Registration
Since openEuler itself is open to gitee.com, you need to have an account on gitee. I also sincerely hope that gitee can grow into a world-class code hosting platform.
Register a community account and sign the mulan V2 agreement. The open source agreement is very important. If you don’t know, you can learn about it;
How to get involved in the community
-
To submit some requirements or bugs , simply put, if you find something that is not working well, you can make a request directly. Or you find some problems while using openEuler, and then you need to raise this issue in the community.
-
Correcting bugs for the community is a higher level of community participation. At this level, participants essentially enter the community as a developer. Generally speaking, we advocate that in addition to raising questions, we also hope that everyone can solve problems.
-
Contribute software packages and find that openEuler is missing a software package. Help openEuler fill in this package. In fact, the process of contributing software packages is the process of helping openEuler provide richer functions. We hope that with everyone’s participation, openEuler can become an “all-inclusive” software ecosystem.
-
Develop new software , have some ideas of your own, develop a brand new software independently, and contribute this software to the openEuler community and become a part of the openEuler release.
The above four ways to participate in the community are from low to high in difficulty, and there is an article that teaches you how to participate in detail: https://www.infoq.cn/article/miENi1pmmQoDLQrmd9SA
