RabbitMQ 安装使用教程

环境 CentOS7 + Python3.5

yum -y install epel-release erlang socat
cd /usr/local/src
wget http://www.rabbitmq.com/releases/rabbitmq-server/v3.6.15/rabbitmq-server-3.6.15-1.el7.noarch.rpm
yum install rabbitmq-server-3.6.15-1.el7.noarch.rpm 

插件列表查询： rabbitmq-plugins list
开启管理功能： rabbitmq-plugins enable rabbitmq_management

增加访问用户，默认用户guest只能本地访问。
rabbitmqctl add_user admin 123456

设置用户角色： rabbitmqctl set_user_tags admin administrator
权限设置：rabbitmqctl set_permissions [-p vhostpath] {user} {conf} {write} {read}
    conf:    一个正则表达式match哪些配置资源能够被该用户访问。
    write:    一个正则表达式match哪些配置资源能够被该用户读。
    read:    一个正则表达式match哪些配置资源能够被该用户访问。
    
权限设置示例：  rabbitmqctl set_permissions -p / admin ".*" ".*" ".*"

列出所有用户：    rabbitmqctl list_users
删除用户：    rabbitmqctl delete_user {username}
修改用户密码：    rabbitmqctl change_password {username} {newpassword}

启动：    rabbitmq-server -detached
关闭：    rabbitmqctl stop
服务器状态：    rabbitmqctl status 
集群状态：    rabbitmqctl cluster_status
添加vhost:     rabbitmqctl add_vhost {name}
删除vhost:     rabbitmqctl delete_vhost {name}

channel.queue_declare(queue="hello-queue") #声明队列
channel.queue_bind(queue="hello-queue", exchange="hello-exchange", routing_key="hola")  # 使用路由键绑定队列和交换器

def msg_consumer(channel, method, header, body):    # 处理消息
    channel.basic_ack(delivery_tag=method.delivery_tag)  # 消息确认
    print ("%d : '%s' " %(method.delivery_tag, body) )
    if body == b'quit':     # 这里的 body 是 bytes 类型
        channel.basic_cancel(consumer_tag="hello-consumer") # 停止消费并退出
        channel.stop_consuming()
        return

# 订阅消费者
channel.basic_consume( msg_consumer, queue="hello-queue", consumer_tag="hello-consumer")
channel.start_consuming() # 开始消费
