运行须知：
1.  该项目由C++编写，运行需要配置好g++或类似环境。
2.  该项目使用到的库有 muduo，json（项目附有），hiredis，mysqlclient，pthread。
3.  该项目服务器使用到了nginx的TCP负载均衡，需要配置好才能运行。

ngnix的TCP负载均衡模块配置：

stream{

        upstream Myserver{
                server 127.0.0.1:6001 weight=1 max_fails=3 fail_timeout=30s;
                server 127.0.0.1:6002 weight=1 max_fails=3 fail_timeout=30s;

        }



        server{

        listen 6000;
        proxy_pass Myserver;

}
