RabbitMQ的基础安装与使用

安装

主机部署

http://www.rabbitmq.com/install-rpm.html

选择RPM包下载，选择对应平台，本次安装在CentOS 7，其它平台类似。

由于使用了erlang语言开发，所以需要erlang的包。erlang和RabbitMQ的兼容性

参考https://www.rabbitmq.com/which-erlang.html#compatibility-matrix

下载rabbitmq-server-3.7.16-1.el7.noarch.rpm、erlang-21.3.8.6-1.el7.x86_64.rpm。socat在CentOS中源中有

# yum install erlang-21.3.8.6-1.el7.x86_64.rpm rabbitmq-server-3.7.16-1.el7.noarch.rpm

或者在线安装

https://www.rabbitmq.com/install-rpm.html#yum-legacy

新建yum源

$ vim /etc/yum.repos.d/rabbitmq.repo

更新所有软件

$ yum update -y

安装依赖

$ yum install socat logrotate -y

安装

$ yum install erlang rabbitmq-server -y

容器部署

docker-compose容器编排清单

version: '3'
services:
    rabbitmq:
      image: rabbitmq:3.11.7-management
      restart: always
      ports:
      - "15672:15672"
      - "5672:5672"
      container_name: rabbitmq
      environment:
        RABBITMQ_DEFAULT_USER: admin
        RABBITMQ_DEFAULT_PASS: admin
      volumes:
      - ./data/:/var/lib/rabbitmq
      - /usr/share/zoneinfo/Asia/Shanghai:/etc/localtime

启动插件

$ docker-compose exec rabbitmq rabbitmq-plugins enable rabbitmq_management rabbitmq_mqtt rabbitmq_web_mqtt

配置

http://www.rabbitmq.com/configure.html#config-location

环境变量

使用系统环境变量，如果没有使用rabbitmq-env.conf 中定义环境变量，否则使用缺省值

RABBITMQ_NODE_IP_ADDRESS the empty string, meaning that it should bind to all network interfaces.

RABBITMQ_NODE_PORT 5672

RABBITMQ_DIST_PORT RABBITMQ_NODE_PORT + 20000 内部节点和客户端工具通信用

RABBITMQ_CONFIG_FILE 配置文件路径默认为/etc/rabbitmq/rabbitmq

环境变量文件，可以不配置

插件管理

列出所有可用插件

$ rabbitmq-plugins list

启动WEB管理插件，会依赖启用其它几个插件。

$ rabbitmq-plugins enable rabbitmq_management

The following plugins have been enabled:

  rabbitmq_management

  rabbitmq_management_agent

  rabbitmq_web_dispatch
set 3 plugins.
[E ] rabbitmq_management               3.7.16
[e ] rabbitmq_management_agent         3.7.16
[e ] rabbitmq_web_dispatch             3.7.16

启动服务

$ systemctl start rabbitmq-server

启动中，可能出现下面的错误

Error when reading /var/lib/rabbitmq/.erlang.cookie: eacces

就是这个文件的权限问题，修改属主、属组为rabbitmq即可

$ chown rabbitmq.rabbitmq /var/lib/rabbitmq/.erlang.cookie: eacces

服务启动成功

$ ss -ntlp| grep 5672
LISTEN     0      128          *:15672                    *:*                   users:(("beam.smp",pid=90005,fd=35))
LISTEN     0      128          *:25672                    *:*                   users:(("beam.smp",pid=90005,fd=18))
LISTEN     0      128       [::]:5672                  [::]:*                   users:(("beam.smp",pid=90005,fd=33))

用户管理

新建管理员用户

使用guest/guest只能本地地登录，远程登录会报错

rabbitmqctl

rabbitmqctl [-n <node>][-t timeout] [-l][-q] <command> [<command options>]
General options:
    -n node              
    -q, --quiet            
    -t,--timeout timeout
    -l longnames
Commands:
    add_user <username> <password>        添加用户
    list_users                            列出用户
    delete_user username                  删除用户
    change_password <username> <password> 修改用户名、密码
    set_user_tags <username> <tag> [...]  设置用户tag
    list_user_permissions <username>      列出用户权限

添加用户:
rabbitmqctl add_user username password

删除用户:
rabbitmqctl delete_user username
更改密码:
rabbitmqctl change_password username newpassword
设置权限Tags，其实就是分配组
rabbitmqctl set_user_tags username tag

查看所有用户

rabbitmqctl list_users

设置hxg用户为管理员tag后登录

$ rabbitmqctl add_user hxg hxg
Adding user "hxg" ...
$ rabbitmqctl list_users

Listing users ...

hxg   []

guest   [administrator]
$ rabbitmqctl set_user_tags hxg administrator
Setting tags for user "hxg" to [administrator] ...
$ rabbitmqctl list_users

Listing users ...

hxg   [administrator]

guest   [administrator]
