QTalk是基于ejabberd，根据业务需要改造而来。修改和扩展了很多 ejaberd不支持的功能。
- 分布式：去掉了依赖mnesia集群的代码，来支持更大的集群，以及防止由于网络分区导致的集群状态不一致。
- 消息处理：通过ejabberd和kafka相连接，实现了消息的路由和订阅发布，可以对消息添加更丰富的处理逻辑。

IM核心组件，负责维持与客户端的长连接和消息路由
IM负载均衡组件，负责验证客户端身份，以及转发http请求到对应的后台服务
IM HTTP接口服务，负责IM相关数据的查询、设置以及历史消息同步
- qtalk_cowboy(后面所有的接口都会迁移到im_http_service，这个服务会废弃)
IM HTTP接口服务，负责IM相关数据的查询、设置以及历史消息同步，后面会全部迁移到im_http_service上
IM文件服务，负责文件的上传和下载
- redis
IM缓存服务
- postgresql
IM数据库服务
前提条件：
- 所有项目都安装到/home/work下面
- 安装用户和用户组是：foo:foo，要保证foo用户有sudo权限
- 家目录下有download文件夹，所有文件会下载到该文件夹下
- 数据库用户名密码是ejabberd:123456，服务地址是：127.0.0.1
- redis密码是：123456，服务地址是：127.0.0.1
- 数据库初始化sql在doc目录下
- 保证可访问主机的：5222、5202、8080端口
- IM服务的域名是:qtalk.test.org
