【RabbitMQ】【Docker】基于docker-compose构建rabbitmq容器_Erlang

本文通过docker-compose构建一个单体的rabbtimq容器。

1，docker、docker-compose环境

首先需要有docker和docker-compose环境，docker安装[1]，docker-compose安装[2]。

通过下列命令确定docker、docker-compose是否安装成功。

[root@192 gengzhihao]# docker version
client: docker engine - community
 version:           25.0.3
 api version:       1.44
 go version:        go1.21.6
 git commit:        4debf41
 built:             tue feb  6 21:17:10 2024
 os/arch:           linux/amd64
 context:           default

server: docker engine - community

  version:          25.0.3
  api version:      1.44 (minimum version 1.24)

  git commit:       f417435
  built:            tue feb  6 21:16:08 2024

  gitcommit:        ae07eda36dd25f8a1b98dfbf587313b99c0190bb
 runc:
  version:          1.1.12
  gitcommit:        v1.1.12-0-g51d5e94
 docker-init:
  version:          0.19.0
  gitcommit:        de40ad0

[root@192 bin]# docker-compose version
docker compose version v2.24.6

2，构建dockerfile，启动容器

docker-compose在/usr/local/bin里，我们就在/usr/local下构建一个docker-compose目录，里面再构建各级不同容器的目录，用于构建dockerfile和挂载目录[3]。

[root@192 bin]# cd /usr/local
[root@192 local]# ls
bin  docker-mount  etc  games  include  lib  lib64  libexec  mongodb  mycat  mysql  sbin  share  src
[root@192 local]# mkdir docker-compose
[root@192 local]# ls
bin             docker-mount  games    lib    libexec  mycat  sbin   src
docker-compose  etc           include  lib64  mongodb  mysql  share
[root@192 local]# cd docker-compose/
[root@192 docker-compose]# mkdir rabbitmq
[root@192 docker-compose]# cd rabbitmq/

在其中构建dockerfile

[root@192 rabbitmq]# vim docker-compose.yml

内容如下：

version: '3.1'
services:
  rabbitmq:
    restart: always
    image: daocloud.io/library/rabbitmq:3.8.8
    volumes:
      - ./data/:/var/lib/rabbitmq/
      - ./log/:/var/log/rabbitmq/log/
    ports:
      - 15672:15672
      - 5672:5672

启动rabbitmq的容器，curl其端口看一下是否正常返回amqp，docker ps看一下容器名字是什么，后面进入容器内部用得上。

[root@192 rabbitmq]# docker-compose up -d

启动的时候，有的时候会报错，

error response from daemon: head "https://daocloud.io/v2/library/rabbitmq/manifests/3.8.8": get "https://daohub-auth.daocloud.io/auth?scope=repository%3alibrary%2frabbitmq%3apull&service=daocloud.io": net/http: request canceled (client.timeout exceeded while awaiting headers)

解决方法就是多试几次命令就好[4]。

3，进入容器，配置可视化界面

进入容器，进入其/opt/rabbitmq目录，其中plugins和sbin目录书我们需要注意的。进入容器时用到的容器名字，是docker ps时查看到的rabbitmq容器的名字。

[root@192 rabbitmq]# docker exec -it rabbitmq-rabbitmq-1 /bin/bash
root@39dc5f01ded3:/# cd /opt/rabbitmq/
root@39dc5f01ded3:/opt/rabbitmq# ls
install				license-bsd-base64js	     license-mit-flot	    license-mpl		  etc
license				license-bsd-recon	     license-mit-mochi	    license-mpl-rabbitmq  plugins
license-apache2			license-isc-cowboy	     license-mit-sammy	    license-erlcloud	  sbin
license-apache2-explorercanvas	license-mit-ejs		     license-mit-sammy060   license-httpc_aws	  share
license-apache2-excanvas	license-mit-ejs10	     license-mit-jquery     license-rabbitmq_aws
license-apl2-stomp-websocket	license-mit-erlware-commons  license-mit-jquery164  escript

进入plugins目录，可以看到一个 rabbitmq_management-3.8.8.ez，是可视化界面需要用到的脚本，复制rabbitmq_management，版本号不用记。

root@39dc5f01ded3:/opt/rabbitmq/plugins# ls

去和plugins同级的sbin目录下，开启可视化界面

root@39dc5f01ded3:/opt/rabbitmq/plugins# cd ../sbin/
root@39dc5f01ded3:/opt/rabbitmq/sbin# ls
rabbitmq-defaults     rabbitmq-env	rabbitmq-queues  rabbitmq-upgrade
rabbitmq-diagnostics  rabbitmq-plugins	rabbitmq-server  rabbitmqctl
root@39dc5f01ded3:/opt/rabbitmq/sbin# ./rabbitmq-plugins enable rabbitmq_management
enabling plugins on node rabbit@39dc5f01ded3:

the following plugins have been configured:

  rabbitmq_prometheus
  rabbitmq_web_dispatch
applying plugin configuration to rabbit@39dc5f01ded3...
the following plugins have been enabled:
  rabbitmq_management

started 1 plugins.

这是在linux的浏览器中访问localhost:15672，即可看到可视化界面，账号密码都是guest。
