NSQ是一个实时的分布式消息平台。它的设计目标是为在多台计算机上运行的松散服务提供一个现代化的基础设施骨架。

NSQ是由3个进程组成的：

• nsqd 是一个接收、排队、然后转发消息到客户端的进程。
• nsqlookupd管理拓扑信息并提供最终一致性的发现服务。
• nsqadmin用于实时查看集群的统计数据（并且执行各种各样的管理任务）。

1 源码部署

软件下载直接去官网：https://nsq.io/deployment/installing.html

cd /usr/local/nsq-1.1.0.linux-amd64.go1.10.3/bin/
nohup ./nsqlookupd > /dev/null 2>&1 &
nohup ./nsqd --lookupd-tcp-address=127.0.0.1:4160 > /dev/null 2>&1 &
nohup ./nsqadmin --lookupd-http-address=127.0.0.1:4161 > /dev/null 2>&1 &

2 docker部署nsq

获取镜像

docker pull nsqio/nsq

启动容器

• 运行lookupd

~docker run -d --name lookupd -p 4160:4160 -p 4161:4161 nsqio/nsq /nsqlookupd
450cbab82b8eb491d42bf105185c1022010b4d05e65a04f6c52ba15e1f5af06f

• 获取docker host的IP地址

~ docker inspect -f '{{ .NetworkSettings.IPAddress }}' lookupd
172.17.0.2

• 运行nsqd

# --broadcast-address=广播到虚拟机地址
~ docker run -d --name nsqd -p 4150:4150 -p 4151:4151 nsqio/nsq /nsqd --broadcast-address=172.17.0.1 --lookupd-tcp-address=172.17.0.2:4160
3bc0901c8c485c351cfe31b0ef1a4fa32bf6bf148f0d74907afec6cbb1e4a034

• 运行nsqadmin

~ docker run -d --name nsqadmin -p 4171:4171 nsqio/nsq /nsqadmin  --lookupd-http-address=172.17.0.2:4161

注意：宿主机防火墙是否有拦截

• 查看docker容器是否正常启动运行

~ docker ps -a

3 docker-compose部署

创建docker-compose.yml

➜  nsq pwd
/root/nsq
➜  nsq vim docker-compose.yml

文件内容如下

version: '2'
services:

  nsqlookupd:
    image: nsqio/nsq
    command: /nsqlookupd
    networks:
      - nsq-network
    hostname: nsqlookupd
    ports:
      - "4161:4161"
      - "4160:4160"
      
  nsqd:
    image: nsqio/nsq
    # -broadcast-address=宿主机地址 
    command: /nsqd --lookupd-tcp-address=nsqlookupd:4160 -broadcast-address=172.17.0.1
    depends_on:
      - nsqlookupd
    hostname: nsqd
    networks:
      - nsq-network
    ports:
      - "4151:4151"
      - "4150:4150"
      
  nsqadmin:
    image: nsqio/nsq
    command: /nsqadmin --lookupd-http-address=nsqlookupd:4161
    depends_on:
      - nsqlookupd
    hostname: nsqadmin
    ports:
      - "4171:4171"
    networks:
      - nsq-network
 
networks:
  nsq-network:
    driver: bridge

配置检查

docker-compose config

启动 docker-compose

➜  nsq docker-compose up -d
Starting nsq_nsqlookupd_1_a12f31d6a776 ... done
Starting nsq_nsqd_1_1c0db410157f       ... done
