How to Install RabbitMQ on CentOS 7
RabbitMQ is a widely used open-source message broker written in the Erlang programming language. As a message-oriented middleware, RabbitMQ can be used to implement the Advanced Message Queuing Protocol (AMQP) on all modern operating systems.
This article explains how to install RabbitMQ on a Vultr Ubuntu 16.04 server instance.
Before getting started, you need to:
- Deploy a brand new Vultr Ubuntu 16.04 server instance.
- Log into the server as a non-root sudo user.
Step 1: Update the system
Use the following commands to update your Ubuntu 16.04 system to the latest stable status:
sudo apt-get update sudo apt-get upgrade
Step 2: Install Erlang
Since RabbitMQ is written in Erlang, you need to install Erlang before you can use RabbitMQ:
cd ~ wget http://packages.erlang-solutions.com/site/esl/esl-erlang/FLAVOUR_1_general/esl-erlang_20.1-1~ubuntu~xenial_amd64.deb sudo dpkg -i esl-erlang_20.1-1/~ubuntu/~xenial_amd64.deb
Verify your installation of Erlang:
You will be brought into the Erlang shell which resembles:
Erlang/OTP 20 [erts-9.1] [source] [64-bit] [smp:8:8] [ds:8:8:10] [async-threads:10] [hipe] [kernel-poll:false] Eshell V9.1 (abort with ^G)
Ctrl+C twice to quit the Erlang shell.
Step 3: Install RabbitMQ
Add the Apt repository to your Apt source list directory (
echo "deb https://dl.bintray.com/rabbitmq/debian xenial main" | sudo tee /etc/apt/sources.list.d/bintray.rabbitmq.list
Next add our public key to your trusted key list using
wget -O- https://www.rabbitmq.com/rabbitmq-release-signing-key.asc | sudo apt-key add -
Run the following command to update the package list:
sudo apt-get update
sudo apt-get install rabbitmq-server
Step 4: Start the Server
sudo systemctl start rabbitmq-server.service sudo systemctl enable rabbitmq-server.service
You can check the status of RabbitMQ:
sudo rabbitmqctl status
By default RabbitMQ creates a user named “
guest” with password “
guest”. You can also create your own administrator account on RabbitMQ server using following commands. Change
password to your own password.
sudo rabbitmqctl add_user admin password sudo rabbitmqctl set_user_tags admin administrator sudo rabbitmqctl set_permissions -p / admin ".*" ".*" ".*"
Step 5: Enable and use the RabbitMQ management console
Enable the RabbitMQ management console so that you can monitor the RabbitMQ server processes from a web browser:
sudo rabbitmq-plugins enable rabbitmq_management sudo chown -R rabbitmq:rabbitmq /var/lib/rabbitmq/
Next, you need to setup an administrator user account for accessing the RabbitMQ server management console. In the following commands, “
mqadmin” is the administrator’s username, “
mqadminpassword” is the password. Remember to replace them with your own.
sudo rabbitmqctl add_user mqadmin mqadminpassword sudo rabbitmqctl set_user_tags mqadmin administrator sudo rabbitmqctl set_permissions -p / mqadmin ".*" ".*" ".*"
Now, visit the following URL:
Log in with the credentials you had specified earlier. You will be greeted with the RabbitMQ remote management console, where you can learn more about RabbitMQ.
