Linux安装和配置nsq

NSQ简介

NSQ 是一个实时分布式消息平台，旨在大规模运行，每天处理数十亿条消息。

它提倡没有单点故障的分布式和分散式拓扑结构，实现容错和高可用性，同时保证可靠的消息传递。请看特点和保证。

在操作上，NSQ很容易配置和部署（所有参数都在命令行上指定，编译的二进制文件没有运行时的依赖性）。为了获得最大的灵活性，它与数据格式无关（消息可以是JSON、MsgPack、协议缓冲区或其他任何形式）。官方的Go和Python库是开箱即用的（还有许多其他的客户端库），如果你有兴趣建立自己的库，有一个协议规范。

特点:

• 追求简单部署

• 追求高可用、避免单点故障、无中心设计

• 确保消息送达

• 生产者消费者自动发现、消费者连接所有生产者、向消费者推的模式

• 提供 HTTP 接口

• 提供几乎所有编程语言的客户端开发包

NSQ是由知名短链接服务商bitly用Go语言开发的实时消息处理系统，具有高性能、高可靠、无视单点故障等优点，是一个非常不错的新兴的消息队列解决方案。

下载和安装nsq

官方安装地址:https://nsq.io/overview/quick_start.html

官方下载地址:https://nsq.io/deployment/installing.html

#创建目录,并进入
mkdir -p /data/software
cd /data/software

#下载nsq包
wget https://s3.amazonaws.com/bitly-downloads/nsq/nsq-0.3.8.linux-amd64.go1.6.2.tar.gz

#解压
tar -zxvf nsq-0.3.8.linux-amd64.go1.6.2.tar.gz

#复制到指定目录
cp -r /data/software/nsq-0.3.8.linux-amd64.go1.6.2 /data/beyond/nsq

启动时可配置文件的参考地址: https://liushuchun.gitbooks.io/mixapi/content/nsq_config.html

启动相关服务

nohup /data/beyond/nsq/bin/nsqd &
#（守护进程；接收，缓存和投递消息给客户端）  如：nsqd -config=/home/nsq/bin/nsqd.cfg

nohup /data/beyond/nsq/bin/nsqlookupd &
#（守护进程；为消费者提供运行时发现服务，来查找指定话题（topic）的生产者 nsqd） 

nohup /data/beyond/nsq/bin/nsqadmin &
#（提供 Web 页面用来实时的管理你的 NSQ 集群。它通过和 nsqlookupd 实例交流，来确定生产者）

指定端口启动 nohup /data/beyond/nsq/bin/nsqadmin --lookupd-http-address localhost:4160 &

指定配置文件启动 nohup /data/beyond/nsq/bin/nsqlookupd -config=/data/beyond/nsq/conf/nsqlookupd.cfg &

nohup /data/beyond/nsq/bin/nsqadmin -config=/data/beyond/nsq/conf/nsqadmin.cfg &

nohup /data/beyond/nsq/bin/nsqd -config=/data/beyond/nsq/conf/nsqd.cfg &

集群管理 记得谁说过，go调用nsq时，只能在代码里配置多个地址，去轮询调用
