下载RabbitMQ安装包
[root@localhost ~]# wget https://packagecloud.io/rabbitmq/rabbitmq-server/packages/el/7/rabbitmq-server-3.7.7-1.el7.noarch.rpm [root@localhost ~]# yum -y localinstall rabbitmq-server-3.7.7-1.el7.noarch.rpm
启用RabbitMQ的web插件
[root@localhost ~]# rabbitmq-plugins enable 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 ~]# netstat -ntlp Active Internet connections (only servers) Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name tcp 0 0 0.0.0.0:111 0.0.0.0:* LISTEN 1/systemd tcp 0 0 0.0.0.0:4369 0.0.0.0:* LISTEN 38383/epmd tcp 0 0 192.168.122.1:53 0.0.0.0:* LISTEN 1253/dnsmasq tcp 0 0 0.0.0.0:22 0.0.0.0:* LISTEN 1015/sshd tcp 0 0 127.0.0.1:631 0.0.0.0:* LISTEN 1012/cupsd tcp 0 0 127.0.0.1:25 0.0.0.0:* LISTEN 1182/master tcp 0 0 0.0.0.0:25672 0.0.0.0:* LISTEN 38454/beam.smp tcp6 0 0 :::111 :::* LISTEN 1/systemd tcp6 0 0 :::4369 :::* LISTEN 38383/epmd tcp6 0 0 :::22 :::* LISTEN 1015/sshd tcp6 0 0 ::1:631 :::* LISTEN 1012/cupsd tcp6 0 0 ::1:25 :::* LISTEN 1182/master tcp6 0 0 :::5672 :::* LISTEN 38454/beam.smp
开机启动rabbit
[root@localhost ~]# systemctl enable rabbitmq-server
启动rabbitmq
[root@localhost ~]# systemctl restart rabbitmq-server Job for rabbitmq-server.service failed because the control process exited with error code. See "systemctl status rabbitmq-server.service" and "journalctl -xe" for details.
查看状态
[root@localhost ~]# systemctl status rabbitmq-server ● rabbitmq-server.service - RabbitMQ broker Loaded: loaded (/usr/lib/systemd/system/rabbitmq-server.service; enabled; vendor preset: disabled) Active: active (running) since Tue 2019-01-15 01:24:21 CST; 1min 19s ago Process: 41443 ExecStop=/usr/sbin/rabbitmqctl shutdown (code=exited, status=69) Main PID: 41607 (beam.smp) Status: "Initialized"
一般这个状态是因为文件".erlang.cookie"用户和用户组权限的问题
将该文件通过chown授权给rabbitmq
启动rabbitmq，查看端口
[root@localhost ~]# netstat -antlp | grep 5672 tcp 0 0 0.0.0.0:15672 0.0.0.0:* LISTEN 3641/beam.smp tcp 0 0 0.0.0.0:25672 0.0.0.0:* LISTEN 3641/beam.smp tcp 0 0 127.0.0.1:25672 127.0.0.1:56251 TIME_WAIT - tcp6 0 0 :::5672 :::* LISTEN 3641/beam.smp
浏览器访问测试
用户名密码都是guest
rabbit搭建完成!
RabbitMQ使用方法
查看当前的连接
[root@localhost ~]# rabbitmqctl list__connectios
列出多有队列及队列的消息数
[root@localhost ~]# rabbitmqctl list__queues
查看当前队列消息
[root@localhost ~]# rabbitmqctl status
Status of node rabbit@localhost ...
[{pid,3641},
...
设置用户权限为超级管理员权限
[root@localhost ~]# rabbitmqctl set_user_tags root administartor
创建虚拟机管理消息队列
[root@localhost ~]# rabbitmqctl add_vhost read Adding vhost "read" ...
删除虚拟机
[root@localhost ~]# rabbitmqctl delete_vhost read
查看当前虚拟机
[root@localhost ~]# rabbitmqctl list_vhosts Listing vhosts ... / ##默认虚拟机 read
RabbitMQ用户管理、角色和权限管理
创建用户
[root@localhost ~]# rabbitmqctl add_user {user}root {password}123456
删除用户
[root@localhost ~]# rabbitmqctl add_user {username}
修改用户密码
[root@localhost ~]# rabbitmqctl change_password {username} {newpassword}
查看用户列表
[root@localhost ~]# rabbitmqctl list_users
使用python调用rabbitmq测试
安装py
[root@localhost ~]# yum -y install python-pip
安装epel扩展源
[root@localhost ~]# yum -y install epel-release
更新pip
[root@localhost ~]# pip install --upgrade pip
安装pika模块
[root@localhost ~]# pip install pika
创建生产者代码
[root@localhost ~]# cat send.py
#!/bin/env python
import pika
#指定连接的主机参数为localhost
connection=pika.BlockingConnection(pika.ConnectionParameters(host='localhost'))
#连接引导
channel=connection.channel()
#声明rabbitmq的队列BindingKey
channel.queue_declare(queue='hello')
#指定Exchange匹配模式，指定RoutingKey
channel.basic_publish(exchange='',
routing_key='hello',
body='Hello World!')
print("[x] Sent 'Hello World'")
#关闭连接
connection.close()
创建消费者代码
[root@localhost ~]# cat receive.py
#!/usr/bin/env python
import pika
#指定连接的主机参数为localhost
connection = pika.BlockingConnection(pika.ConnectionParameters(host='localhost'))
#连接引导
channel = connection.channel()
#声明rabbitmq的队列BindingKey
channel.queue_declare(queue='hello')
#指定调用的消息
def callback(ch, method, properties, body):
print(" [x] Received %r" % body)
channel.basic_consume(callback,
queue='hello',
no_ack=True)
print(' [*] Waiting for messages. To exit press CTRL+C')
channel.start_consuming()
测试脚本
[root@localhost ~]# python send.py [x] Sent 'Hello World'
查看浏览器，消息队列产生了两个(脚本执行两次)且已处理完成
