NSQ无法获取消息

Question

我是这样看的：nsq cannot consume message by connecting to nsqlookupd

但他并不适用于我，所有的方式都可以被tried.It的环境。

系统: VMware CentOS + Docker-compose NSQ版本:全部最新

docker-compose.yml：

version: '3'
services:
  nsqlookupd:
    image: nsqio/nsq
    command: /nsqlookupd
    ports:
      - "4160:4160"
      - "4161:4161"
  nsqd:
    image: nsqio/nsq
    command: /nsqd --lookupd-tcp-address=nsqlookupd:4160
    depends_on:
      - nsqlookupd
    ports:
      - "4150:4150"
      - "4151:4151"
  nsqadmin:
    image: nsqio/nsq
    command: /nsqadmin --lookupd-http-address=nsqlookupd:4161
    depends_on:
      - nsqlookupd
    ports:
      - "4171:4171"

我尝试在NSQD命令中添加-broadcast-address=127.0.0.1，但它会导致管理员页面错误。

docker-compose配置

services:
  nsqadmin:
    command: /nsqadmin --lookupd-http-address=nsqlookupd:4161
    depends_on:
    - nsqlookupd
    image: nsqio/nsq
    ports:
    - 4171:4171/tcp
  nsqd:
    command: /nsqd --lookupd-tcp-address=nsqlookupd:4160 -broadcast-address=127.0.0.1
    depends_on:
    - nsqlookupd
    image: nsqio/nsq
    ports:
    - 4150:4150/tcp
    - 4151:4151/tcp
  nsqlookupd:
    command: /nsqlookupd
    image: nsqio/nsq
    ports:
    - 4160:4160/tcp
    - 4161:4161/tcp
version: '3.0'

我希望你能理解我的意思，毕竟我的英语很差，你对此有什么想法吗？

func Producer() {
    producer, err := nsq.NewProducer("192.168.132.128:4150", nsq.NewConfig())
    if err != nil {
        fmt.Println("NewProducer", err)
        panic(err)
    }

    for i := 0; i < 5; i++ {
        if err := producer.Publish("test", []byte(fmt.Sprintf("Hello World "))); err != nil {
            fmt.Println("Publish", err)
            panic(err)
        }
    }
}

此代码成功他可以将消息添加到nsqd，但我无法连接到nsqd

看看这个：

2019/07/05 14:19:00 INF    2 [test/testq] querying nsqlookupd http://192.168.132.128:4161/lookup?topic=test
2019/07/05 14:19:00 INF    2 [test/testq] (60366475943f:4150) connecting to nsqd
2019/07/05 14:19:01 ERR    2 [test/testq] (60366475943f:4150) error connecting to nsqd - dial tcp: i/o timeout

还有这个

{"channels":["testq"],"producers":[{"remote_address":"172.19.0.2:57250","hostname":"60366475943f","broadcast_address":"60366475943f","tcp_port":4150,"http_port":4151,"version":"1.1.0"}]}

我认为问题出现在查找连接NSQ，但我不知道如何处理他。

Answer 1

我想你忘了什么。您是否已将其添加到/etc/hosts中

127.0.0.1 nsqd

它允许您的计算机识别带有docker上的nsq网络的本地网络。希望这能对你有所帮助。CMIIW。

Answer 2

我试着按照下面的方式添加，

--broadcast-address=nsqd

因此您docker组成应该如下所示，

nsqd:
  command: /nsqd --lookupd-tcp-address=nsqlookupd:4160 --broadcast-address=nsqd
  depends_on:
  - nsqlookupd
  image: nsqio/nsq
  ports:
  - 4150:4150/tcp
  - 4151:4151/tcp

它现在应该可以工作了
