RabbitMQ - SSL Example

SSL-Example for Python and Java Clients from https://www.rabbitmq.com/ssl.html.

Docker - RabbitMQ-Server

Simple use docker-compose to create a docker rabbitmq container with ssl support.

cd Docker
docker-compose up

RabbitMQ-Server Certificates

SSL Certificate Generation

Rabbitmq ssl-tutorial --> https://www.rabbitmq.com/ssl.html

Using tls-gen's tool from michael klishin --> https://github.com/michaelklishin/tls-gen

git clone https://github.com/michaelklishin/tls-gen
cd tls-gen/basic
# private key password
make PASSWORD=bunnies
make verify
make info

ls -l ./result
# Files generated in result folder
--> ca_certificate.pem
--> ca_key.pem
--> client_certificate.pem
--> client_key.p12
--> client_key.pem
--> server_certificate.pem
--> server_key.p12
--> server_key.pem

Create a Java Keystore File

https://docs.cloudera.com/documentation/enterprise/5-10-x/topics/cm_sg_openssl_jks.html

cd result

keytool.exe -importkeystore -srckeystore server_key.p12
  -srcstoretype PKCS12 -srcstorepass bunnies 
  -deststorepass bunnies -destkeypass password 
  -destkeystore server_store.jks

SSL Certificate Setup

Copy /Certificates/testca/cacert.pem, /Certificates/server/key.pem and /Certificates/server/cert.pem to /etc/ssl/rabbit/ to setup certificate example files to establish a RabbitMQ-TLS connection.

cd /etc/ssl/
mkdir rabbit
cd <GIT_Project_PATH>
cp /Certificates/testca/cacert.pem /etc/ssl/rabbit/cacert.pem
cp /Certificates/server/cert.pem /etc/ssl/rabbit/cert.pem
cp /Certificates/server/key.pem /etc/ssl/rabbit/key.pem

SSL-Configuration

Copy this example file for RabbiMQ and restart service.

Old syntax by rabbitmq.config

[
  {rabbit, [
     {ssl_listeners, [5671]},
     {ssl_options, [{cacertfile,"/etc/ssl/rabbit/cacert.pem"},
                    {certfile,"/etc/ssl/rabbit/cert.pem"},
                    {keyfile,"/etc/ssl/rabbit/key.pem"},
                    {verify,verify_peer},
                    {fail_if_no_peer_cert,true}]}
   ]}
].

New syntax by rabbitmq.conf

listeners.tcp = none
listeners.ssl.default = 5671

ssl_options.cacertfile           = /etc/ssl/rabbit/ca_certificate.pem
ssl_options.certfile             = /etc/ssl/rabbit/server_certificate.pem
ssl_options.keyfile              = /etc/ssl/rabbit/server_key.pem
ssl_options.verify               = verify_peer
ssl_options.fail_if_no_peer_cert = true

Execute Examples

Use Java (Gradle) or Python examples to execute examples.

Python

Python client is split up for a consumer (rabitssl_consume.py) and producer (rabitssql_send.py). Producer sends a message to RabbitMQ-Server and consumer receives this message. PIKA is needed to establish connections.

cd Python
python rabitssql_consume.py/rabitssql_send.py

Java

Java client sends and receives message from a single main file. Simple use Gradle to build and run example.

cd Java
gradle run

Spring-Boot-amqp

RabbitMQ-SSL Spring-Boot example can be build and executed to use Gradle. Clients sends by scheduled task every 5 seconds a sample message.

cd Spring
gradle bootRun
