1. Linux C++ muduo 库学习——库的编译安装

1. 下载

https://github.com/chenshuo/muduo

2. 安装依赖库

1. 安装 boost 库

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

下面我们测试一下 boost 库

#define BOOST_BIND_GLOBAL_PLACEHOLDERS#include <iostream>
#include <boost/bind.hpp>
#include <string>
using namespace std;class Hello
{
public:void say(string name) { cout << name << " talk to America.!" << endl; }
};int main()
{Hello h;auto func = boost::bind(&Hello::say, &h, "Li si");func();return 0;
}

代码写好了，开始编译一下：

g++ test.cpp -o test -std=c++11

2. 安装 cmake

sudo apt install cmake  -y

3. 编译

./build.sh

4. 手动安装头文件和 .a （默认静态编译）

1. 头文件

sudo cp muduo/ /usr/include/

2. 库文件

进入到 build 目录下面的 lib 目录，将所有文件拷贝到

sudo cp * /usr/local/lib/

5. 测试 muduo 库

创建一个 C++ 文件

#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();
}

代码编译：

g++ test_muduo1.cc -o test_muduo1 -lmuduo_net -lmuduo_base -lpthread -std=c++11

测试：
终端1：

./test_muduo1 

终端2：

echo "hello world" | nc localhost 8888

测试结果如下：
