即时通讯系统源码（完整开源的即时通讯系统源码下载）

即时通讯系统源码介绍

这是一个完整开源的即时通讯系统源码，该系统可以在Android、iOS和PC三个平台上运行。源码压缩包内有详细搭建教程。

这款即时通讯系统源码，服务器的配置要求4核CPU,4G内存，5M带宽（这是最低要求），如果配置太低，可能会引起卡顿，影响用户体验。

这款即时通讯系统源码是一个可以在Android、iOS和PC三个平台上运行的即时通讯独立系统源码。安装该通讯系统的步骤包括安装宝塔，替换Nginx配置文件，上传服务端并解压缩，以及配置IP和启动文件服务。

安装Nginx ，安装好Nginx 去配置文件把以下复制进去
