Go *** 作nsq

创作不易感谢支持。
一条主写Go和PHP的小菜鸟。平常有时间喜欢自己写点东西，如有不对的地方，欢迎大佬指点。 个人博客：太阳上的雨天 地址：http://blog.caixiaoxin.cn 善于分享，希望有助他人. 非常感谢各位大佬的关注和支持

Go *** 作nsq 一. 基于docker-compose 搭建nsq集群 二. nsq 简单了解 nsqd：一个负责接收、排队、转发消息到客户端的守护进程nsqlookupd：管理拓扑信息并提供最终一致性的发现服务的守护进程nsqadmin：一套Web用户界面，可实时查看集群的统计数据和执行各种各样的管理任务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 三. docker-compose.yml

version: "3"
services:
   my-nsq-admin:
     image: nsqio/nsq:v1.1.0
     command: /nsqadmin -lookupd-http-address my-nsq-nsqlookupd1:4161 -lookupd-http-address my-nsq-nsqlookupd2:4261
     ports:
     - "4171:4171"
   my-nsq-nsqd1:
     image: nsqio/nsq:v1.1.0
     hostname: my-nsq-nsqd1
     command: /nsqd -tcp-address 0.0.0.0:4150 -data-path /usr/local/nsq/bin/data --http-address 0.0.0.0:4151 -lookupd-tcp-address my-nsq-nsqlookupd1:4160 -lookupd-tcp-address my-nsq-nsqlookupd2:4260 -broadcast-address my-nsq-nsqd1
     volumes:
     - "./data1:/usr/local/nsq/bin/data"
     ports:
     - "4150:4150"
     - "4151:4151"
   my-nsq-nsqd2:
     image: nsqio/nsq:v1.1.0
     hostname: my-nsq-nsqd2
     command: /nsqd -tcp-address 0.0.0.0:4250 -data-path /usr/local/nsq/bin/data -http-address 0.0.0.0:4251 -lookupd-tcp-address my-nsq-nsqlookupd1:4160 -lookupd-tcp-address my-nsq-nsqlookupd2:4260 -broadcast-address=my-nsq-nsqd2
     volumes:
     - "./data2:/usr/local/nsq/bin/data"
     ports:
     - "4250:4250"
     - "4251:4251"
   my-nsq-nsqd3:
     image: nsqio/nsq:v1.1.0
     hostname: ysdp-nsq-nsqd3
     command: /nsqd -tcp-address 0.0.0.0:4350 -data-path /usr/local/nsq/bin/data --http-address 0.0.0.0:4351 -lookupd-tcp-address my-nsq-nsqlookupd1:4160 -lookupd-tcp-address my-nsq-nsqlookupd2:4260 -broadcast-address=my-nsq-nsqd3
     volumes:
     - "./data3:/usr/local/nsq/bin/data"
     ports:
     - "4354:4350"
     - "4355:4351"
   my-nsq-nsqlookupd1:
     image: nsqio/nsq:v1.1.0
     command: /nsqlookupd -http-address 0.0.0.0:4161 -tcp-address 0.0.0.0:4160 -broadcast-address my-nsq-nsqlookupd1
     ports:
     - "4160:4160"
     - "4161:4161"
   my-nsq-nsqlookupd2:
     image: nsqio/nsq:v1.1.0
     command: /nsqlookupd -http-address 0.0.0.0:4261 -tcp-address 0.0.0.0:4260 -broadcast-address my-nsq-nsqlookupd2
     ports:
     - "4260:4260"
     - "4261:4261"

四. 启动集群

docker-compose up -d

浏览器访问：127.0.0.1:4171/nodes

五. 配置本机hosts

因为基于nsqlookupd 的数据发现需要访问broadcast-address 暴露的地址，所以需要配置，同时都需要加上

127.0.0.1 my-nsq-nsqd1
127.0.0.1 my-nsq-nsqd2
127.0.0.1 my-nsq-nsqd3

六. Go使用
