docker+rocketMQ中的坑（一）brokerIP1 设置无效

### 1、安装rocketMQ

#### 安装nameserver rocketmq:server-4.5.2

```

docker run -d -p 9876:9876  --network mynetwork --ip 10.20.0.11 --name rmqserver  foxiswho/rocketmq:server-4.5.2

```

#### 安装broker  rocketmq:broker-4.5.1

```

docker run -d -p 10911:10911 -p 10909:10909 --network mynetwork --ip 10.20.0.12 --name rmqbroker --link rmqserver:namesrv -e "NAMESRV_ADDR=namesrv:9876" -e "JAVA_OPTS=-Duser.home=/opt" -e "JAVA_OPT_EXT=-server -Xms128m -Xmx128m" -v /config/rocketmq/broker.conf:/etc/rocketmq/broker.conf  foxiswho/rocketmq:broker-4.5.1

```

#### 安装rocketmq console  styletang/rocketmq-console-ng:latest

```

docker run -d --name rmqconsole -p 8180:8080  --network mynetwork --ip 10.20.0.13 --link rmqserver:namesrv\

-e "JAVA_OPTS=-Drocketmq.namesrv.addr=namesrv:9876\

-Dcom.rocketmq.sendMessageWithVIPChannel=false"\

-t styletang/rocketmq-console-ng

```

ps:这种方式启动后 远程访问 broker的地址总是显示的docker的内网地址 例如上面设定的10.20.0.12:10911  看网上说修改broker的配置文件 /etc/rocketmq/broker.conf 中的 brokerIP1 为外网地址 

```

brokerClusterName = DefaultCluster

brokerName = broker-a

brokerId = 0

namesrvAddr = 192.168.199.177:9876  #内网地址，将broker的IP告诉nameserver

brokerIP1 = 61.188.xxx.xx  #修改为自己的外网地址

deleteWhen = 04

fileReservedTime = 48

brokerRole = ASYNC_MASTER

flushDiskType = ASYNC_FLUSH

```

然而，没有卵用，还是内网地址，真是搞人心态。

为了验证不是MQ本身的其他问题，我将测试项目放到线上去运行，地址就用docker的内网地址，结果没有意外的成功发送和接受了。所以MQ没有问题，还是地址设置的问题。

#### 采用 docker-compose去部署

所以，我换了docker-compose的方式去部署，加上使用配置文件启动的命令，并自定义了网络，再做尝试，docker-compose.yml文件如下：

```

version: '3.5'

services:

  rmqnamesrv:

    image: foxiswho/rocketmq:server-4.5.2

    container_name: rmqnamesrv

    ports:

      - 9876:9876

    volumes:

      - /opt/rocketmq/logs:/opt/logs

      - /opt/rocketmq/store:/opt/store

    environment:

      JAVA_OPT_EXT: "-Duser.home=/opt -Xms128m -Xmx128m -Xmn128m"

    networks:

        rmq:

          aliases:

            - rmqnamesrv

  rmqbroker:

    image: foxiswho/rocketmq:broker-4.5.1

    container_name: rmqbroker

    ports:

      - 10909:10909

      - 10911:10911

    volumes:

      - /opt/rocketmq/logs:/opt/logs

      - /opt/rocketmq/store:/opt/store

      - /opt/rocketmq/conf/broker.conf:/etc/rocketmq/broker.conf

    environment:

        JAVA_OPT_EXT: "-Duser.home=/opt -server -Xms128m -Xmx128m -Xmn128m"

    command: ["/bin/bash","mqbroker","-c","/etc/rocketmq/broker.conf","-n","rmqnamesrv:9876","autoCreateTopicEnable=true"]  #这里设置了配置文件

    depends_on:

      - rmqnamesrv

    networks:

      rmq:

        aliases:

          - rmqbroker

  rmqconsole:

    image: styletang/rocketmq-console-ng

    container_name: rmqconsole

    ports:

      - 8180:8080

    environment:

        JAVA_OPTS: "-Drocketmq.namesrv.addr=rmqnamesrv:9876 -Dcom.rocketmq.sendMessageWithVIPChannel=false"

    depends_on:

      - rmqnamesrv

    networks:

      rmq:

        aliases:

          - rmqconsole

networks:

  rmq:

    name: rmq

    driver: bridge

```

命令如下

docker-comose stop/start/rm/restart/logs

然而，还是访问的内网地址，准备放弃。

但是，我还是不愿意就这么算了。

接着我查看docker-compose logs rmqconsole 查看日志

```2019-12-02 22:42:11 INFO ShutdownHook - Try to shutdown service thread:TransactionalMessageCheckService started:true lastThread:Thread[TransactionalMessageCheckService,5,main]

2019-12-02 22:42:11 INFO ShutdownHook - shutdown thread TransactionalMessageCheckService interrupt false

2019-12-02 22:42:50 INFO main - rocketmqHome=/opt/rocketmq-4.5.1  #这句话比较关键

2019-12-02 22:42:50 INFO main - namesrvAddr=rmqnamesrv:9876

2019-12-02 22:42:50 INFO main - brokerIP1=172.22.0.3  #日志显示也是用的内部地址

2019-12-02 22:42:50 INFO main - brokerIP2=172.22.0.3

```

这时候我就开始觉得，是不是初始化的时候根本就没有读取/etc/rocketmq/broker.conf这个配置文件，而是还有别的。

于是我就去  日志提示的 rocketMQ的项目路径下去一探究竟。rocketmqHome=/opt/rocketmq-4.5.1

```

[root@2bf75e4b1aa2 rocketmq-4.5.1]# cd /opt/rocketmq-4.5.1/

[root@2bf75e4b1aa2 rocketmq-4.5.1]# ls

LICENSE  NOTICE  README.md  benchmark  bin  conf  lib                     

#bin下为执行文件  例如关闭broker 就用 sh mqshutdown broker

# conf为配置文件

[root@2bf75e4b1aa2 rocketmq-4.5.1]# cd conf/

[root@2bf75e4b1aa2 conf]# ls

2m-2s-async  2m-2s-sync  2m-noslave  broker.conf.old  dledger  logback_broker.xml  logback_namesrv.xml  logback_tools.xml  plain_acl.yml  tools.yml

# broker.conf.old 这个文件引起了我的注意，他的内容和 /etc/rocket/broker.conf一样，我就严重怀疑，是不是初始化读取的就是这个文件。

#于是我修改了，内容同上，重启容器，开始祈祷。。。。。

```

```

```

一切索然无味，浪费我大好青春。

#### 总结 broker-4.5.1这个版本，配置文件读取的是/opt/rocketmq-4.5.1/broker.conf.old这个文件，因此修改它即可。
