2 application fields of Linux 2.1 People desktop field application
- This area is the weakest link of traditional Linux application, traditional Linux has been suppressed by windows because of its simple interface, complicated operation and the disadvantage of application.
- However, in recent years, with the emergence of excellent desktop environment such as Ubuntu and Fedora, and the increasing support of major hardware vendors, the occupancy rate of Linux in the field of personal desktops is increasing gradually.
2.2 Server domain
- Linux is the strongest application in the server domain.
- Linux free, stable, efficient and so on has been very good embodiment, this year, the Linux server market has been a rapid upgrade, especially in some high-end areas particularly extensive.
2.3 Embedded Field
- In recent years, the application of Linux in the field of embedded has also been improved rapidly.
- Linux is stable, good support for the network, low cost, and can be cut according to the needs of the software, the kernel can reach the minimum of hundreds of KB, making its application in the embedded field has been greatly improved in recent years.
- Main applications: Set-top box, digital TV, VoIP, PBX, mobile phone, smart home, smart hardware, etc. are its application fields.
3 The path of Advanced Linux experts
- Linux is an open source, free operating system, its stability, security, processing and multi-concurrency has been recognized by the industry, many medium-sized, large and even cluster projects are using Linux, many software companies consider the development cost of Linux preferred.
- The advanced path of Linux is as follows
- Basic operation commands in ①linux environment, including file operation commands, use of editing tools, Linux user management, etc.
- Various configurations of the ②LINUX (environment variable configuration, network configuration, service configuration).
- ③linux how to build the corresponding language development environment (big Data, Java EE, Python, etc.).
- ④ can write shell scripts to maintain Linux servers.
- ⑤ can make security settings, prevent attacks, ensure the normal operation of the server, the system can be tuned.
- ⑥ in-depth understanding of the Linux system (research on the kernel), proficient in large-scale website application architecture, and familiar with the Brother link deployment and maintenance methods.
