基于UNIX的数据库应用系统设计

Design of database application system based on UNIX

基于安全问题的考虑,提出了以UNIX+MySql框架为基础的数据库应用系统的设计方案.该系统与其它系统相比,具有稳定性、经济性、安全性和高效性的特点,同时在该系统结构中增加了前置服务器.前置服务器物理上为双网卡结构,一个用来与外界通讯,另一个用来与后置数据库服务器通讯,从而实现了杜绝外界客户直接访问后置数据库的功能.

Based on the security of system,the design scheme of UNIX + MYSQL used for the database application is presented.Compared with others,this system is more stable,more economical, more secure and more effective. The frontend server which is physically stored double NIC (Network Interface Card) is adopted. One NIC will complete the communication with Internet clients,the other is used to communicate with the backend server.In this way, any access to backend server from the outside will be refused.
