1. 首先安装boost库；

sudo apt-get update
sudo apt-get install libboost-all-dev

2. 下载muduo库， https://github.com/chenshuo/muduo

3. 解压后进入解压目录，vim CMakeLists.txt，注释掉略过unit_test测试用例代码的编译，节省编译时间；

4. 未安装cmake则先安装；

apt-get install cmake

5. 执行muduo-master目录下的build.sh编译

./build.sh

6. 安装muduo库

./build.sh install

7. 进入与muduo-master同级的build目录，将muduo头文件和lib库文件分别拷贝到系统路径下：

（1）包含头文件的muduo文件夹拷贝到/usr/include

（2）lib库文件拷贝到/usr/local/lib

此时g++会自动从系统路径找muduo库.

8. 编码测试

#include <muduo/net/TcpServer.h>
#include <muduo/base/Logging.h>
#include <boost/bind.hpp>
#include <muduo/net/EventLoop.h>// 使用muduo开发回显服务器
class EchoServer
{public:EchoServer(muduo::net::EventLoop* loop,const muduo::net::InetAddress& listenAddr);void start(); private:void onConnection(const muduo::net::TcpConnectionPtr& conn);void onMessage(const muduo::net::TcpConnectionPtr& conn,muduo::net::Buffer* buf,muduo::Timestamp time);muduo::net::TcpServer server_;
};EchoServer::EchoServer(muduo::net::EventLoop* loop,const muduo::net::InetAddress& listenAddr): server_(loop, listenAddr, "EchoServer")
{server_.setConnectionCallback(boost::bind(&EchoServer::onConnection, this, _1));server_.setMessageCallback(boost::bind(&EchoServer::onMessage, this, _1, _2, _3));
}void EchoServer::start()
{server_.start();
}void EchoServer::onConnection(const muduo::net::TcpConnectionPtr& conn)
{LOG_INFO << "EchoServer - " << conn->peerAddress().toIpPort() << " -> "<< conn->localAddress().toIpPort() << " is "<< (conn->connected() ? "UP" : "DOWN");
}void EchoServer::onMessage(const muduo::net::TcpConnectionPtr& conn,muduo::net::Buffer* buf,muduo::Timestamp time)
{// 接收到所有的消息，然后回显muduo::string msg(buf->retrieveAllAsString());LOG_INFO << conn->name() << " echo " << msg.size() << " bytes, "<< "data received at " << time.toString();conn->send(msg);
}int main()
{LOG_INFO << "pid = " << getpid();muduo::net::EventLoop loop;muduo::net::InetAddress listenAddr(8888);EchoServer server(&loop, listenAddr);server.start();loop.loop();
}

编译：

g++ main.cpp -lmuduo_net -lmuduo_base -lpthread -std=c++11

服务端运行后，打开新的shell作为客户端，输入以下nc命令测试连接。

echo "hello world" | nc localhost 8888

若成功，则服务端会显示如下：
