RabbitMQ是流行的開源消息隊列系統，用erlang語言開發。
安裝（Windows）:
Windows：
首先需要安裝 Erlang環境
官網:
http://www.erlang.org/
Windows版下載地址:http://www.erlang.org/download/otp_win64_17.3.exe
Linux版: 使用yum安裝
安裝模塊 pip install pika
Linux（centos7）：
安裝都是需要Erlang環境的。
wget rpm -Uvh erlang-solutions-1.0-1.noarch.rpm rpm --import http://packages.erlang-solutions.com/rpm/erlang_solutions.asc yum install erlang
erlang 安裝完成後，開始安裝rabbitmq。
從官網下載（http://www.rabbitmq.com）rpm包；
rpm -ivh rabbitmq-server-3.4.1-1.noarch.rpm #安裝
service rabbitmq-server start #啓動
chkconfig rabbitmq-server on #開機自啓動
#編輯配置文件
cp /usr/share/doc/rabbitmq-server-3.4.1/rabbitmq.config.example /etc/rabbitmq/rabbitmq.config
vim /etc/rabbitmq/rabbitmq.config
%% The default "guest" user is only permitted to access the server
%% via a loopback interface (e.g. localhost).
%% {loopback_users, [<<"guest">>]},
%%
%% Uncomment the following line if you want to allow access to the
%% guest user from anywhere on the network.
{loopback_users, []} #將改行取消註釋，即允許遠程用戶訪問。開啓web界面管理工具
rabbitmq-plugins enable rabbitmq_management #開啓web界面管理工具 systemctl restart rabbitmq-server.service #重啓服務
界面如圖所示，默認端口爲15672.
默認用戶名和密碼均爲 guest
默認網頁是不允許訪問的，需要增加一個用戶修改一下權限，代碼如下：
添加用戶:rabbitmqctl add_user tanx tanx
添加權限:rabbitmqctl set_permissions -p "/" tanx ".*" ".*" ".*"
修改用戶角色rabbitmqctl set_user_tags tanx administrator
然後就可以遠程訪問了，然後可直接配置用戶權限等信息。
set_permissions [-p vhost] {user} {conf} {write} {read}
vhost
The name of the virtual host to which to grant the user access, defaulting to /.
user
The name of the user to grant access to the specified virtual host.
conf
A regular expression matching resource names for which the user is granted configure permissions.
write
A regular expression matching resource names for which the user is granted write permissions.
read
A regular expression matching resource names for which the user is granted read permissions.
rabbitmq常用命令
add_user <UserName> <Password>
delete_user <UserName>
change_password <UserName> <NewPassword>
list_users
add_vhost <VHostPath>
delete_vhost <VHostPath>
list_vhostsset_permissions [-p <VHostPath>] <UserName> <Regexp> <Regexp> <Regexp>
clear_permissions [-p <VHostPath>] <UserName>
list_permissions [-p <VHostPath>]
list_user_permissions <UserName>
list_queues [-p <VHostPath>] [<QueueInfoItem> ...]
list_exchanges [-p <VHostPath>] [<ExchangeInfoItem> ...]
list_bindings [-p <VHostPath>]
list_connections [<ConnectionInfoItem> ...]
2.python代碼
先來一段簡單的代碼實現
producter端
#!/usr/bin/env python
import pika
connection = pika.BlockingConnection(pika.ConnectionParameters(
'localhost'))
channel = connection.channel()
#聲明queue
channel.queue_declare(queue='hello')
#n RabbitMQ a message can never be sent directly to the queue, it always needs to go through an exchange.
channel.basic_publish(exchange='',
routing_key='hello',
body='Hello World!')
print(" [x] Sent 'Hello World!'")
connection.close()customer端
#_*_coding:utf-8_*_
__author__ = 'Alex Li'
import pika
connection = pika.BlockingConnection(pika.ConnectionParameters(
'localhost'))
channel = connection.channel()
#You may ask why we declare the queue again we have already declared it in our previous code.
# We could avoid that if we were sure that the queue already exists. For example if send.py program
#was run before. But we're not yet sure which program to run first. In such cases it's a good
# practice to repeat declaring the queue in both programs.
channel.queue_declare(queue='hello')
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()
