In order to solve the problem that the cost of building a server system for small and medium-sized enterprises is too high, a solution is proposed to build a multi-function server system using free (open-source) software such as CentOS and MySQL. With Ghost technology, you can quickly install a multi-function server system within 30 minutes. The actual application shows that the server system has the advantages of multiple functions, stable performance, convenient upgrade and expansion, and safety and practicality, which can effectively reduce the cost of common software and hardware and meet the basic requirements of most SMEs. This solution can be used as a free server solution for small and medium-sized enterprises and is worth promoting.

With the development of computer technology, network technology, and enterprise information, enterprises are concerned with computer software and hardware (functions, speed), Network (Internet, LAN), security (systems, networks, and information) and Enterprise Informatization requirements are getting higher and higher; routers, firewalls, anti-virus servers, ERP servers, database servers, file servers, printing servers, Web servers, and MAIL servers, FAX servers are also subdivided. Because most enterprises use Microsoft products, according to the Microsoft technical whitepaper, other software systems cannot be installed on servers, that is, different server software must be installed on different machines, with the increase in the number of users (License) or the upgrade of software (from the standard edition to the Enterprise Edition), the number of machines and the cost of software and hardware will become more and more, software and Hardware Management will become more and more complex.

1. How can enterprises reduce the cost of common software and hardware?

Software fees can be reduced by using a variety of solutions, such as using inexpensive software, developing software on your own, or using open-source software Linux. Among these solutions, the current feasible solution is to use Linux, because "Linux has been officially announced for nearly 20 years since 1991.9", and there are many releases and users. Among the many Linux distributions, we chose CentOS as the Server System Software for small and medium-sized enterprises for the following reasons:

"Red Hat Enterprise Linux and Fedora have become mainstream Linux distributions"; "CentOS is the source code re-compiled version of Red Hat Enterprise Linux. CentOS is compatible with RHEL, has many advantages of RHEL."

"CentOS can be regarded as a clone of Red Hat Enterprise Linux, but it is free of charge ."; "CentOS will not have any copyright issues and there is no fee for authentication and support ."

Stable CentOS performance. "With CentOS, you can experience the stability, reliability, and Enterprise functions of Red Hat Enterprise Linux without commercial support ."; "Linux can run continuously for several months or years without restarting, which is especially prominent compared with NT (dead .."

CentOS is powerful. "Linux now has many professional-level databases and office assembly. It includes not only Oracle and IBM databases, but also OpenOffice and Koffice office programs ". For example, CentOS provides a GUI, Firefox, OpenOffice, Java, C ++, Perl, PHP, Mysql, and other script languages, programming languages, and databases, which can be installed on your PC.

Convenient remote management. "Linux Remote Management is very convenient: Linux can be operated through command lines, which is very suitable for remote management. You can use machines installed with any operating system ". For example, you can use Telnet and VNC (graphical interface) to remotely manage the CentOS System in Windows.

"IPTABLES (Linux Firewall) has developed into a powerful firewall that has most of the features that can only be found in proprietary commercial firewalls ."

"RHEL does not have high CPU requirements. If the system simply uses the text mode, the memory requirements are very low. Generally, the computer memory can be used ." Therefore, if you do not select a graphical interface, Chinese character system, or unused features when installing the CentOS system, the system will become faster. You can install many server software on one machine to reduce the number and cost of the machine, it also facilitates centralized management.

Fewer viruses: no virus has been detected in CentOS so far.
