Build a Linux LAN

Create a Linux Lan-Linux Enterprise Application-Linux server application. For more information, see. With the development of Internet, China has successively established CERNET, CSETNET, and CHINANET) and CHINAGBN. In this context, qualified enterprises and institutions are connected with each other, so enterprises need LAN construction solutions.

In the past, most LAN construction solutions were built based on Windows operating systems. A typical solution is to use Windows NT as the operating system of the server and Windows 98 as the operating system of workstation of each user (unit or individual.

However, with the rapid development and popularization of Linux operating systems, the advantages of Linux are fully apparent. Linux has played an important role in LAN construction. Based on the practice, we propose a cost-effective, fast, and reliable Linux LAN construction solution with Turbo Linux as the main operating system. This solution allows LAN users to securely and reliably access internal and external resources.

Linux lan network architecture (NetworkStructure ):

Use a converter to convert the Internet interface to twisted pair wires and connect directly to a dual Nic Server. Another Nic of the Server and other servers and clients are connected to a Hub to form a LAN. The dual-nic server acts as a firewall and gateway to control the security of Intranet and Internet connections. We can also run other services, such as file servers, proxy servers, email servers, and Web servers. Another server can be used as a database server to mainly run database services.

An external Nic must have a formal IP address. Another Nic and another computer Nic can use a private IP address ranging from 192.168.1 ~ 192.168.254 is freely allocated. The Gateway Addresses of other computers point to the internal IP address of the firewall gateway server. The network configuration of the firewall gateway server should be set according to the applied IP address.

Hardware requirements for Linux LAN (Hardware): In this solution, Hardware requirements include two servers and seven PCs, as well as Hardware required for network implementation, such: HUB, network cable, and converter. The most important hardware part is that the server's performance requirements for Linux are very important. Turbo Linux supports Intel's latest Itanium processor, which has great advantages in supporting intel chip servers and PC products. The support for IA-64 and high security and reliability are the reasons for the use of TurboLinux as hardware to support the operating system.

Linux LAN Software requirements ):

The software for the two servers uses TurboLinux 6.0. Run the database software package that comes with Turbo Linux on the database server. The firewall gateway server can run a variety of Internet applications, such as email servers, Web servers, and proxy servers.

The built-in database software packages in Turbo Linux include s SQL and MySQL, which have their own advantages. PostgresSQL is better than structured specifications and functions, while MySQL is faster. Both have a large number of development tools and interfaces in various languages, making it easy to develop. However, it should be noted that the MySQL database does not have the row lock and nested Select functions. When selecting it, you should consider more. Software Installation and debugging for servers should be completed by Linux engineers or professionals.

The design of this scheme fully considers the scalability, openness and maintainability of the system, and can adapt to the development requirements. It also meets the demands of information management for high speed, high reliability and multi-application.
