Because Web Server products are designed for a certain type of network operating system, they are incompatible with each other Website Design The dynamic web page in is interpreted and executed by the Web Server, that is, the dynamic web page design technology is determined by the Web Server. Therefore, the construction of e-commerce website application environment depends on the selected network operating system. This section mainly introduces the construction methods of several mainstream Web application environments. In the Internet environment, UNIX, NT and Linux are the three major network operating systems.
1、 UNIX operating system
Among many network operating systems, UNIX is an old qualified network operating system. It is outstanding in security and stability. Servers using UNIX rarely appear crash, system paralysis, etc. It has very strict protection measures for file and directory permissions, user permissions, and data. UNIX also has its shortcomings. From the perspective of application, UNIX has the disadvantage of complex operation and management, which is difficult for ordinary users to master. Because the UNIX system itself is huge, the correlation between different functions is strong, there are many versions, and it is strongly associated with machine equipment. For example, AIX is used on IBM minicomputers, Solaris is used on SUN minicomputers, and Didial Unix is used on DEC minicomputers. In general, UNIX applications focus on large high-end network application areas, such as establishing Internet websites, establishing WAN or large LAN. There is a certain distance between them and ordinary small and medium-sized network users, and they are rarely used in small and medium-sized networks.
2、 Windows NT/2000 operating system
Windows NT and Linux developed rapidly. Windows NT was affordable and easy to use. It had a familiar operating interface similar to Windows 2000. With the high market share of Windows desktop system, it steadily occupied the market share of small and medium-sized enterprises. NT has won the favor of small and medium-sized enterprises for its outstanding advantages such as easy use and management, friendly interface, simple configuration, etc. Users can economically build and maintain their own networks without too much professional knowledge. NT has a wealth of network protocols, including TCP/IP, IPS/SPX, PPP, etc., which can be used as the operating system of the server, and can easily be interconnected with the remote city network and Internet through routers, X.25, DDN, etc. NT integrates many network service functions, such as DNS, RAS, DHCP, etc., with high practicability. The network management function of NT is powerful. It can easily add new users and establish shared directories. In addition, NT also shows excellent performance in terms of security, stability and reliability, which is suitable for small and medium-sized network users. At the same time of seizing the city network market of the bureau, NT has squeezed into the ranks of the Internet competition. At present, some websites also use NT in large quantities when they are set up.
3、 Linux operating system
Linux is rapidly expanding its customer base with its open source code and low price. Linux is the product of the network age, which is a kind of free software. The so-called freedom means that users can obtain programs and a source code for free, and can easily add their own expanded functions. Linux is designed and developed by many excellent programmers. Numerous users have participated in testing and debugging. After seven or eight years of development, Linux has finally been recognized by users. Linux inherits the excellent design idea of UNIX and is fully compatible with UNIX. It is a multi-user and multi task operating system with built-in network support and can be seamlessly connected with Netware, NT, UNIX, etc. Linux can run on a variety of hardware platforms. Low requirements for hardware, high stability and reliability of the system, and high cost performance ratio.
