139.1. RabbitMQ

RabbitMQ

139.1.1. 安装 RabbitMQ

running on 127.0.0.1 (localhost) on port 5672 (standard AMQP port).

139.1.1.1. Ubuntu

			
$ sudo apt-get install rabbitmq-server			
			

			

139.1.1.2. CentOS

			
# yum install -y rabbitmq-server
# chkconfig rabbitmq-server on
# service rabbitmq-server start			
			

			

添加用户, 添加权限, 删除guest用户

			
# rabbitmqctl add_user rabbit password
# rabbitmqctl set_permissions -p "/" rabbit ".*" ".*" ".*"
# rabbitmqctl delete_user guest			
			

			

139.1.1.3. OSCM 一键安装

			
curl -s https://raw.githubusercontent.com/oscm/shell/master/mq/rabbitmq/rabbitmq-server-3.6.10.sh | bash

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

139.1.1.4. 检查端口

			
[root@netkiller ~]# ss -lnt | grep 5672
LISTEN 0 128 *:25672 *:*
LISTEN 0 128 :::5672 :::*			
						
			

139.1.2. 配置 RabbitMQ

创建配置文件,默认情况/etc/rabbitmq/下面什么都没有。你需要从共享文档中复制一份配置文件过去。

		
cp /usr/share/doc/rabbitmq-server-3.6.10/rabbitmq.config.example /etc/rabbitmq/rabbitmq.config
		
		

139.1.2.1. 监听所有适配器地址

默认 RabbitMQ 监听 localhost 如果你需要让外部机器连接进来,需要配置 tcp_listeners 0.0.0.0

			
 {tcp_listeners, [{"0.0.0.0",5672}]}		
			
			

139.1.3. rabbitmqctl - command line tool for managing a RabbitMQ broker

			rabbitmqctl status
		

139.1.3.1. change_password

			
rabbitmqctl change_password admin <new_password>
			
			

139.1.3.2. list_users

			
# rabbitmqctl list_users
Listing users ...
guest [administrator]
...done.			
			
			

139.1.3.3. 虚拟机管理

			
$ rabbitmqctl add_vhost test
$ rabbitmqctl add_user testuser password
$ rabbitmqctl set_permissions -p test testuser ".*" ".*" ".*"			
						
			

139.1.3.4. list_queues

			
# rabbitmqctl list_queues
Listing queues ...
amq.gen-RhBwbb9EdZ8Fgk_heGZQ2w 0
bb 0
customer 276930
demo 0
email 0
example 0
hello 1
members_id 282
new_members_id 0
q_linvo 0
real 0
...done.
				
			

			
			

139.1.3.5. list_exchanges

			
# rabbitmqctl list_exchanges
Listing exchanges ...
direct
amq.direct direct
amq.fanout fanout
amq.headers headers
amq.match headers
amq.rabbitmq.log topic
amq.rabbitmq.trace topic
amq.topic topic
email direct
...done.
			
			

139.1.4. rabbitmq-plugins - command line tool for managing RabbitMQ broker plugins

启用插件

		
rabbitmq-plugins enable rabbitmq_management		
		
		

139.1.4.1. rabbitmq_management

RabbitMQ Management HTTP API (https://cdn.rawgit.com/rabbitmq/rabbitmq-management/rabbitmq_v3_6_0/priv/www/api/index.html)

启用插件 Management and Monitoring 插件

						
rabbitmq-plugins enable rabbitmq_management
systemctl restart rabbitmq-server
