摘　　要：传统的即时通讯系统的弊端之一是数据库I/O次数频繁,因为在IM中大量短而多的消息持续在磁盘的数据库上进行读写。为了解决数据库造成的系统瓶颈,选取Mysql和内存Key-Value引擎的No SQL数据库Redis两级存储,从而给出基于XMPP的即时通讯系统高可用的优化方案。One of the drawbacks of the traditional instant messaging system is the frequent number of database I / O,because a large number of short messages in IM continue to read and write on the disk database. In order to solve the system bottleneck caused by the database, the NoSQL database Redis two-level storage of Mysql and Key-Value engine of memory is selected, and the optimization scheme of XMPP-based instant communication system is presented
