摘　　要：基于视频课程的学习平台用户体验差的问题是一个困扰运维人员的技术难点。本文采用集群与镜像技术对某学习平台进行部署架构改造:通过Nginx代理服务器做负载均衡的Session保持,通过Redis技术实现Session保存与共享,解决了集群环境下学习平台Session丢失的问题;通过镜像技术和学习平台Web服务器、FTP课程服务器与学员用户设备IP地址绑定,实现了视频课程稳定输出,解决了学习平台用户体验差、视频播放不流畅的问题。The problem of poor user experience in the learning platform based on video course is a technical difficulty that disturbs the operation and maintenance personnel.In this paper,cluster and mirroring technologies are adopted to transform the deployment architecture of the learning platform.Session retention is performed by Nginx proxy server for load balancing and Session storage and sharing is realized by Redis technology,which solves the problem of Session loss of the learning platform in the cluster environment.By binding the learning platform WEB server,FTP course server and the student user device IP address,the stable output of the video course is realized.It solves the problems of poor user experience and uneven video playback on the learning platform.

关 键 词：Session保持与共享 镜像 负载均衡 IP地址hash绑定
