# 2.相关概念 #

nsqlookupd：管理nsqd节点拓扑信息并提供最终一致性的发现服务的守护进程  
    nsqd：负责接收、排队、转发消息到客户端的守护进程，并且定时向nsqlookupd服务发送心跳  
    nsqadmin：nsq的web统计界面，可实时查看集群的统计数据和执行一些管理任务  
    utilities：常见基础功能、数据流处理工具，如nsq\_stat、nsq\_tail、nsq\_to\_file、nsq\_to\_http、nsq\_to\_nsq、to\_nsq

nsq官网下载二进制linux安装包：nsq-1.0.0-compat.linux-amd64.go1.8.tar.gz  
      解压到家目录tar -xvzf nsq-1.0.0-compat.linux-amd64.go1.8.tar.gz  
给bin目录下文件添加执行权限

cd ~/nsq-1.0.0-compat.linux-amd64.go1.8
    sudo chmod -R u+x bin/

## 3.1.简单启动 ##

进入bin目录

打开一个终端，启动nsqlookupd

nohup ./nsqlookupd &

打开另一个终端，启动nsqd

nohup ./nsqd --lookupd-tcp-address=127.0.0.1:4160 &

打开另一个终端，启动nsqadmin

nohup ./nsqadmin --lookupd-http-address=127.0.0.1:4161 &

访问nsqadmin监控

http://127.0.0.1:4171

打开另外一个终端，启动nsq\_to\_file，将消息写入/tmp文件的日志文件，文件名默认由主题topic+主机+日期时间戳组成

nohup ./nsq_to_file --topic=test --output-dir=/tmp --lookupd-http-address=127.0.0.1:4161 &

使用curl命令，发布一条消息

curl -d 'hello world' 'http://127.0.0.1:4151/pub?topic=test'

## 3.2本地多nsq启动     ##

把~nsq/bin目录加入path

### start.sh ###

#!/bin/sh
    #服务启动
    #lookupd:151 152
    #更改 --data-path 所指定的数据存放路径，否则无法运行
    echo '删除日志文件'
    rm -rf ./log/*
    
    echo '启动nsqlookupd服务'
    nohup nsqlookupd >./log/nsqlookupd.log 2>&1 &
    
    
    echo '启动nsqd服务'
    nohup nsqd --lookupd-tcp-address=0.0.0.0:4160 -tcp-address="0.0.0.0:4153" --data-path=./data1  >./log/nsqd1.log 2>&1 &
    nohup nsqd --lookupd-tcp-address=0.0.0.0:4160 -tcp-address="0.0.0.0:4154" --data-path=./data2 -http-address="0.0.0.0:4155" >./log/nsqd2.log 2>&1 &
    
    
    echo '启动nsqdadmin服务'
    nohup nsqadmin --lookupd-http-address=127.0.0.1:4161 >./log/nsqadmin.log 2>&1 &

### stop.sh ###

#!/bin/sh
    #服务停止
    ps -ef | grep nsq| grep -v grep | awk '{print $2}' | xargs kill -2

## 3.2集群nsq启动 ##

假设我们的服务器安装下面要求编排。

### nsqlookup 集群列表 ###

192.168.234.77
    192.168.234.36
    192.168.234.39

### nsq 节点 ###

192.168.234.117
    192.168.234.118

### nsqadmin 节点 ###

192.168.234.119

###    构建环境变量 ###

设置nsq的环境变量，假设nsq的bin路径在/usr/local/software/nsq下。

运行命令如下：

vi /etc/profile
    export NSQ_HOME=/usr/local/software/nsq
    export PATH=$PATH:$NSQ_HOME/bin
    
    . /etc/profile

### 构建运行脚本 ###

创建执行脚本,分别创建start-nsqlookup.sh, start-nsq.sh和 start-nsqadmin.

### start-nsqlookup.sh ###

#nsqlookup
    eval nsqlookupd --verbose > nsqlookup.log 2>&1 "&"

### start-nsq.sh  ###

#nsq 
    eval nsqd –data-path=/usr/local/software/nsq/data –lookupd-tcp-address=192.168.234.77:4160,192.168.234.36:4160,192.168.234.39:4160 > nsqd.log 2>&1 “&”

### start-nsqadmin.sh  ###

#nsqadmin 
    eval nsqadmin –lookupd-http-address=192.168.234.77:4161,192.168.234.36:4161,192.168.234.39:4161 > nsqadmin.log 2>&1 “&”

# 运行脚本 #

首先需要安装次序运行上面的脚本，**必选先运行nsqlookup集群，在运行start-nsqadmin.sh或者start-nsq.sh.**

在对应服务器上执行对应的脚本。

## nsqlookup节点 ##

\#192.168.234.77  
\#192.168.234.36  
\#192.168.234.39  
sh start-nsqlookup.sh

## nsq节点上  ##

\#192.168.234.117   
\#192.168.234.118   
sh start-nsq.sh

## nsqadmin节点上  ##

\#192.168.234.119   
sh start-nsqadmin.sh

查看运行效果，可以直接访问nsqadmin节点

http://192.168.234.119:4171/。

## 创建Producer ##

package main
    
    import (
        "log"
        "github.com/bitly/go-nsq"
        "io/ioutil"
        "strconv"
    )
    var nullLogger = log.New(ioutil.Discard, "", log.LstdFlags)
    
    func sendMsg(message string){
        //init default config
        config := nsq.NewConfig()
    
        w, _ := nsq.NewProducer("192.168.2.117:4150", config)
        err := w.Ping()
        if err != nil {
            //192.168.2.117:4150,192.168.2.68:4150
            log.Fatalln("error ping 10.50.115.16:4150", err)
            // switch the second nsq. You can use nginx or HAProxy for HA.
            w, _ = nsq.NewProducer("192.168.2.68:4150", config)
        }
        w.SetLogger(nullLogger, nsq.LogLevelInfo)
    
        err2 := w.Publish("a-test", []byte(message))
        if err2 != nil {
            log.Panic("Could not connect nsq")
        }
    
        w.Stop()
    }
    func main() {
        for i := 0; i < 2; i ++ {
            sendMsg("msg index "+ strconv.Itoa(i + 10000))
        }
    
    }

恭喜，你已经成功发送两个消息到nsq节点。创建Consumer

package main
    
    import (
        "log"
        "github.com/bitly/go-nsq"
        "fmt"
    )
    
    
    func doSimpleConsumerTask(){
    
        config := nsq.NewConfig()
        q, _ := nsq.NewConsumer("a-test", "ch", config)
        q.AddHandler(nsq.HandlerFunc(func(message *nsq.Message) error {
    
            log.Printf("message: %v", string(message.Body))
            message.Finish()
            return nil
        }))
        lookupAddr := []string {
            "192.168.234.77:4161",
            "192.168.234.36:4161",
            "192.168.234.39:4161",
        }
        err := q.ConnectToNSQLookupds(lookupAddr)
        if err != nil {
            log.Panic("Could not connect")
        }
        <-q.StopChan
    
        stats := q.Stats()
        fmt.Sprintf("message received %d, finished %d", stats.MessagesReceived, stats.MessagesFinished)
    }
    func main(){
        doSimpleConsumerTask()
    }

程序运行输出：

2017/02/23 09:07:50 message: msg index 10000  
2017/02/23 09:07:50 message: msg index 10001  
  
消费者持续接受发送来的信息,运行程序后端。
