(Turn) ZEROMQ installation

Http://youzifei.iteye.com/blog/1698237zeromq 

It took a great effort to install ZEROMQ today.

Here's a look at the process of installing ZEROMQ on Linux

First of all

http://download.zeromq.org/

1. Download the latest version of ZEROMQ

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

2 Decompression

TAR-XVF zeromq-3.1.0-beta.tar.gz

3 Running Configure

./configure--prefix=/data/zeromq (prefix specified installation directory)

4. Make

5. Make install

6. Setting Environment variables

Export cppflags=-i/home/mine/0mq/include/

Export ldflags=-l/home/mine/0mq/lib/

7. Test code

Server.c

#include </data/zeromq/include/zmq.h>

#include <stdio.h>

#include <unistd.h>

#include <string.h>

#include <stdlib.h>

int main (void)

{

void *context = Zmq_init (1);

Socket to talk to clients

void *responder = Zmq_socket (context, zmq_rep);

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 if we do, this would is how we end

Zmq_close (responder);

Zmq_term (context);

return 0;

}

JZMQ is the Java Client for ZEROMQ

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

2../configure

This time requires the configuration of the above environment variables,

also need

Just

Vi/data/zeromq/.bashrc

Export path= $PATH:/data/zeromq/include

Export Ld_library_path= $LD _library_path:/data/zeromq/lib:/data/zeromq/include

The makefile file will be generated as soon as the Configure is finished executing

3.make

4.make Install

Hwserver.java

//

Hello World Server in Java

Binds REP socket to tcp://*:5555

Expects "Hello" from the client, replies with "World"

//

Naveen Chawla <[email protected]>

//

Import Org.zeromq.ZMQ;

public class Hwserver {

public static void Main (string[] args) {

Prepare our context and socket

ZMQ. Context context = Zmq.context (1);

ZMQ. Socket socket = Context.socket (ZMQ. REP);

Socket.bind ("tcp://*:5555");

while (true) {

Byte[] request;

Wait for next request from client

We'll wait for a 0-terminated string (C string) from the client,

So, this server also works with the guide ' s C and C + + "Hello World" clients

Request = SOCKET.RECV (0);

In order to display the 0-terminated string as a string,

We omit the last byte from request

SYSTEM.OUT.PRINTLN ("Received Request: [" +

New String (REQUEST,0,REQUEST.LENGTH-1)//Creates a string from request, minus the last byte

+ "]");

Do some ' work '

try {

Thread.Sleep (1000);

}

catch (Interruptedexception e) {

E.printstacktrace ();

}

Send reply back to client

We'll send a 0-terminated string (C string) back to the client,

So, this server also works with the guide ' s C and C + + "Hello World" clients

String replystring = "World" + "";

Byte[] Reply = Replystring.getbytes ();

reply[reply.length-1]=0; Sets the last byte of the reply to 0

Socket.send (reply, 0);

}

}

}

Hwclient.java

//

Hello World Client in Java

Connects REQ socket to tcp://localhost:5555

Sends "Hello" to server, expects ' world ' back

//

Naveen Chawla <[email protected]>

//

Import Org.zeromq.ZMQ;

public class hwclient{

public static void Main (string[] args) {

Prepare our context and socket

ZMQ. Context context = Zmq.context (1);

ZMQ. Socket socket = Context.socket (ZMQ. REQ);

SYSTEM.OUT.PRINTLN ("Connecting to Hello World server ...");

Socket.connect ("tcp://localhost:5555");

Do ten requests, waiting each time for a response

for (int request_nbr = 0; Request_nbr! =; request_nbr++) {

Create a "Hello" message.

Ensure the last byte of our "Hello" message is 0 because

Our ' Hello World ' server is expecting a 0-terminated string:

String requeststring = "Hello" + "";

byte[] request = Requeststring.getbytes ();

request[request.length-1]=0; Sets the last byte to 0

Send the message

SYSTEM.OUT.PRINTLN ("Sending request" + REQUEST_NBR + "...");

Socket.send (request, 0);

Get the reply.

Byte[] Reply = socket.recv (0);

When displaying reply as a String, omit the last byte because

Our ' Hello World ' server has sent us a 0-terminated string:

System.out.println ("Received reply" + Request_nbr + ": [" + New String (reply,0,reply.length-1) + "]");

}

}
