CentOS下RabbitMQ安装

一、准备环境

由于RabbitMQ是由Erlang语言编写的基于amqp协议的消息代理中间件,所以安装RabbitMQ之前需要先安装Erlang和socat环境。

  • 安装socat
yum -y install socat
  • 安装Erlang
    由于Erlang在默认的YUM存储库中不可用,所以这里是从GitHub上下载rpm安装文件进行安装,下载地址如下(此次环境下载22.1.6版本):
https://github.com/rabbitmq/erlang-rpm/releases/tag/v22.1.6

下载完成后将安装包上传至centos系统

执行下面命令进行安装

rpm -ivh erlang-22.1.6-1.el7.x86_64.rpm
安装Erlang

查看Erlang的版本

[root@localhost opt]# erl -version
Erlang (SMP,ASYNC_THREADS,HIPE) (BEAM) emulator version 10.5.4
[root@localhost opt]#

至此,Erlang环境安装完毕

二、安装RabbitMQ

1. 首先从RabbitMQ官网下载RabbitMQ安装包
image
2. 导入GPG密钥
[root@localhost opt]# rpm --import https://www.rabbitmq.com/rabbitmq-release-signing-key.asc
[root@localhost opt]# 
3. 将RabbitMQ安装包上传到centOS
image

执行下面命令开始安装RabbitMQ

[root@localhost opt]# rpm -ivh rabbitmq-server-3.8.1-1.el7.noarch.rpm 
准备中...                          ################################# [100%]
正在升级/安装...
   1:rabbitmq-server-3.8.1-1.el7      ################################# [100%]
[root@localhost opt]#

至此,RabbitMQ已经安装在CentOS上。

三、配置RabbitMQ

  • 启动RabbitMQ
[root@localhost opt]# systemctl start rabbitmq-server
[root@localhost opt]#
  • 将RabbitMQ设置成开机自启动
[root@localhost opt]# systemctl enable rabbitmq-server
Created symlink from /etc/systemd/system/multi-user.target.wants/rabbitmq-server.service to /usr/lib/systemd/system/rabbitmq-server.service.
[root@localhost opt]# 
  • 查看RabbitMQ状态信息
[root@localhost opt]# systemctl status rabbitmq-server
● rabbitmq-server.service - RabbitMQ broker

[root@localhost opt]#
  • 开启RabbitMQ Web控制台
    RabbitMQ Web控制台默认情况下是关闭的,可以通过以下命令进行开启
[root@localhost opt]# rabbitmq-plugins enable rabbitmq_management
Enabling plugins on node rabbit@localhost:
rabbitmq_management
The following plugins have been configured:
  rabbitmq_management
  rabbitmq_management_agent
  rabbitmq_web_dispatch
Applying plugin configuration to rabbit@localhost...
The following plugins have been enabled:
  rabbitmq_management
  rabbitmq_management_agent
  rabbitmq_web_dispatch

started 3 plugins.
[root@localhost opt]# 

开启RabbitMQ Web控制台之后,还需要为该控制台创建管理用户,

rabbitmqctl add_user admin admin123
rabbitmqctl set_user_tags admin administrator
rabbitmqctl set_permissions -p / admin ".*" ".*" ".*"

以上命令的意思是:新建一个用户名为admin,密码为admin123的用户,并且给该用户设置成administrator的角色,最后给该用户授予访问 “/” 虚拟主机空间的权限


创建管理用户
  • 通过上一步的配置之后,可以通过访问系统的15672端口进行访问RabbitMQ Web控制台,用户名和密码是上一步创建的
