zeromq 安装

今天在安装zeromq的时候费了好大的力气才算装好

下面来回顾一下在linux安装zeromq的过程

首先

http://download.zeromq.org/

1.下载最新版的zeromq

    http://download.zeromq.org/zeromq-3.1.0-beta.tar.gz

2 解压

    tar -xvf zeromq-3.1.0-beta.tar.gz

3 运行configure

    ./configure --prefix=/data/zeromq     (prefix  指定安装目录)

4. make

5. make install

6. 设置环境变量

    export CPPFLAGS=-I/home/mine/0mq/include/

    export LDFLAGS=-L/home/mine/0mq/lib/

7.测试代码

server.c

    zmq_bind (responder, "tcp://192.168.0.185:5555");

    printf("binding on port 5555.\nwaiting client send message...\n");

    while (1) {

        // Wait for next request from client

        zmq_msg_t request;

        zmq_msg_init (&request);

        char buf[32];

        zmq_recv (responder,buf, &request, 0);

        int size = zmq_msg_size (&request);

        char *string = malloc (size + 1);

        memset(string,0,size+1);

        memcpy (string, zmq_msg_data (&request), size);

        printf ("Received Hello string=[%s]\n",string);

        free(string);

        zmq_msg_close (&request);

        // Do some 'work'

        sleep (1);

        // Send reply back to client

        zmq_msg_t reply;

        char res[128]={0};

        snprintf(res,127,"reply:%d",random());

        zmq_msg_init_size (&reply, strlen(res));

        memcpy (zmq_msg_data (&reply), res, strlen(res));

        char buf2[32];

        zmq_send (responder, buf2, &reply, 0);

        zmq_msg_close (&reply);

    }

    // We never get here but if we did, this would be how we end

    zmq_close (responder);

gcc server.c -o server -lzmq   -L/data/zeromq/lib -I/data/zeromq/include 

gcc client.c -o client -lzmq   -L/data/zeromq/lib -I/data/zeromq/include 

./server

./client

jzmq 是zeromq 的java客户端

下载地址

https://github.com/zeromq/jzmq/downloads

1. tar xzf zeromq-jzmq-semver-90-g58c6108.tar.gz

2. ./configure

   这个时候需要上面环境变量的配置,

   还需要

   随便  

    vi /data/zeromq/.bashrc

    export PATH=$PATH:/data/zeromq/include

    export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/data/zeromq/lib:/data/zeromq/include

    只要configure 执行完毕就会生成makefile文件

3.make

4.make install
