基于LDAP的高可用目录服务器的设计与实现

摘要

LDAP stands for Lightweight Directory Access Protocol.It has been widely applied to all most directory servers such as identity authentication system and information management system,etc.With the growing amount of data stored in the directory server users' requests,single centralized directory server can not meet the application re-quirements,How to build LDAP-based directory server availability becomes the current research focus.This paper presents a design scheme which makes the read and write operations of accessing directory server be separated, meanwhile designing an architecture of one master and multi-slave.The design can not only optimize the directory server response time,but also improve the availability of directory server.%LDAP是一种轻量级目录访问协议,现已被广泛应用到身份认证系统、人员信息管理系统等目录服务器中.随着目录服务器存储数据量和用户访问量的不断增长,单一集中式的目录服务器已经不能满足应用需求,如何构建基于 LDAP 的高可用目录服务器成为当下的研究热点.本文提出一种设计方案,将对目录服务器的访问操作进行读写分离,同时设计一主多从的服务架构,不仅可以优化目录服务器的响应时间,而且提高了目录服务器的可用性.
