Preface
Security and stability are the eternal pursuit of operating systems. The security management business of a well-known IT company serves the company's multiple businesses, covering code security management platforms, digital signature platforms, and multiple internal R&D platforms. The bottom layer runs the CentOS 7 operating system. . As CentOS operating system versions are discontinued one after another, it will bring huge risks to the enterprise's security management business. Therefore, CentOS migration and replacement work is urgent.
Anolis OS is committed to becoming the best alternative to CentOS, and has mature migration cases in many industries such as government affairs, finance, transportation, and electricity. After many selections and comparisons, the company set its sights on Inspur KeyarchOS, a commercial version of the operating system developed based on the Anolis OS . KeyarchOS is widely compatible with mainstream software and hardware in the market, ensuring the stable, safe, and efficient operation of user businesses . It has created a complete solution to cope with CentOS outage, which can meet user needs in different scenarios and help users smoothly migrate their businesses.
Business research and evaluation, tailor-made migration plan
The enterprise's security management business involves more than ten cloud business systems , running multiple CentOS versions including CentOS 7.4, CentOS7.6, etc. The application development languages are mainly Python and Java, and its system components include mariadb and nginx Open source databases and middleware including , gnupg, etc.
The overall migration process includes four links: business environment research, migration assessment, migration implementation, and monitoring and operation . For CentOS 7 running in virtual machines, KeyarchOS provides one-click batch in-situ migration tool X2Keyarch. This tool has migration risk assessment functions including software package assessment, hardware assessment, etc., and provides assessment reports to solve the problem during the migration process. Provide support for potential risks and issues. The in situ migration plan is shown in the figure below:
(Figure 1 / In-situ migration plan)
Migration verification to further identify migration risks
Based on the preliminary environmental research and strategy formulation, build a customer business environment model in the laboratory to simulate migration verification, repeatedly verify the accuracy of the migration process, and timely optimize and adjust the migration process, migration tools, etc. based on the problems encountered during the migration process. . For example, during the testing process, it was discovered that the grub2 version of some services was too low, causing migration to fail. By optimizing the underlying logic of the migration tool, the solution to this problem is directly written into the migration tool upgrade logic framework, and a migration solidification plan is formed for such scenarios to fully prepare for the migration of the production environment.
Migration tools help to achieve efficient migration implementation
According to the customer's business situation, according to the importance and scope of the business, a batch and gradual migration strategy is adopted. Prioritize the migration of non-core businesses with smaller impact, and migrate core businesses last. During the migration implementation process, with the help of the X2Keyarch migration tool , the average migration implementation time for each machine was about 10 minutes , which greatly improved the system migration efficiency and shortened business downtime.
After the migration was completed, business systems such as code security management, digital signatures, and security business research and development were successfully run on Inspur Information KeyarchOS. The business system functions were normal and the data was complete. The person in charge of the security management business said that Inspur Information's X2Keyarch migration tool realizes automated migration, which greatly improves migration efficiency and reduces migration adaptation costs. The migrated system runs stably and fully meets the department's business needs.

Work steadily and continue to create industry migration benchmarks
This CentOS migration fully verified the feasibility and reliability of the KeyarchOS migration solution, proved that the KeyarchOS team has excellent capabilities in CentOS migration, and provided valuable experience for subsequent KeyarchOS migration services. At the same time, it was further verified that solutions based on the commercial version of the Dragon Lizard operating system can replace foreign operating system products in IT industry scenarios . As more and more migration projects are implemented, Inspur Information KeyarchOS will continue to set the industry migration benchmark.
As a governing unit of the Dragon Lizard Community, Inspur Information has always practiced the concept of open source and openness, actively participated in community contributions, and jointly promoted the development and prosperity of the operating system. In the future, Inspur Information will continue to contribute to community construction, follow the mainstream technology development trends in the community, and actively meet the opportunities and challenges brought about by the outage of CentOS.
