In Beijing, because Linux technology is widely used, there are many certifications to choose from. The following are some certifications that I think can be considered:

Red Hat Certified Engineer (RHCE): RHCE certification is the highest level certification provided by Red Hat, covering the skills of Linux system management, security and maintenance. In Beijing, RHCE certification holders are very popular because Red Hat has a high market share in enterprise Linux.

Linux foundation certified engineer (lfce): lfce certification is provided by the Linux foundation and one of the top certifications in the field of Linux system management. Holding LFCE certification can prove that you have a deep understanding and comprehensive skills of Linux system.

Oracle certified professional, Linux administration: Oracle is the market leader of database and enterprise software, and its Linux certification is mainly aimed at the management and optimization of Oracle Linux.

in addition to these certifications, there are many other Linux certifications to choose from, including IBM certified advanced system administrator for Linux on z-series certification and NSE certifications from nmap project certification. Choosing which certification is best depends on your personal interests and career planning.

There are many training institutions and online education platforms in Beijing that offer courses related to Linux, which can help you learn and master Linux skills systematically.

in addition, you can choose the appropriate certification by understanding the market demand and industry trends. The IT industry is changing rapidly, so I suggest you pay attention to the latest technical trends and recruitment needs in order to better choose the Linux certification that suits you.

finally, I want to emphasize that no matter which Linux certification you choose, the key is to master the practical operation and problem-solving ability. Theoretical knowledge and test scores are important, but practical experience is also indispensable. Therefore, it is suggested that you do more practical operation and project experience accumulation in order to better understand and apply Linux technology.

In a word, choosing which Linux certification is best needs to consider many factors, including personal interests, career planning, learning resources, market demand and so on. In Beijing, RHCE, LFCE, CompTIA Linux+, SCE and Oracle Certified Professional are all good choices. Through continuous study and practice, you can constantly improve your technical level and competitiveness and lay a solid foundation for future career development.
