AMQP server: RabbitMQ
RabbitMQ is an excellent low-level messaging server. You can use it with different technologies.
Contents
Requirements
You need PostgreSQL + Python
apt-get install postgresql python3
apt-get install python3-amqplib
Installation
Add repository
You must add a new repository for RabbitMQ.
- Even though the name is "testing" it's actually the latest stable version
- They use "testing" as this is not in the "main" Ubuntu repo yet.
[source: http://www.rabbitmq.com/install-debian.html]
vim /etc/apt/sources.list
Add the new repository
deb http://www.rabbitmq.com/debian/ testing main
Add repo key
wget http://www.rabbitmq.com/rabbitmq-signing-key-public.asc
sudo apt-key add rabbitmq-signing-key-public.asc
Update package list
sudo apt-get update
Binary installation
apt-get install rabbitmq-server amqp-tools
Enable plugins
Enable RabbitMQ command line client
rabbitmq-plugins enable amqp_client
Enable web console
rabbitmq-plugins enable rabbitmq_management
Restart server to take on your changes
service rabbitmq-server restart
Now you can access RabbitMQ using the default ports:
- Web console: TCP 15672, http://localhost:15672/
- AMQP Messages: TCP 5672
Create administration user
Create new user, replace rtd by your username.
rabbitmqctl add_user rtd strong_password
Set user rights
rabbitmqctl set_user_tags rtd administrator
rabbitmqctl set_permissions -p / rtd ".*" ".*" ".*"
Remove default guest user
rabbitmqctl delete_user guest
Restart service to take on your changes
service rabbitmq-server restart
Advanced configuration
Change port number
source: https://www.rabbitmq.com/configure.html
If activeMq is install, stop it
service activemq stop
Create or update the configuration file:
vim /etc/rabbitmq/rabbitmq-env.conf
Add the following at the beginning of the file
NODE_PORT=5673
Restart server
service rabbitmq-server restart
Firewall
You must let the OUTPUT unfiltered because RabbitMQ port is dynamic.
You have to open Input TCP 5672 (messages), TCP 15672 (web interface).
vi /etc/init.d/firewall
Add this rules
#rabbitMq
$IPT -A INPUT -p tcp --dport 15672 -j ACCEPT
$IPT -A INPUT -p tcp --dport 5673 -j ACCEPT
Update startup
The server should start at every reboot. The following hack is only required if your installation is old or buggy.
cd /etc/init.d/
update-rc.d rabbitmq-server defaults
