Rabbitmq is a free and open source message broker system that implements the Advanced Message Queuing Protocol (AMQP). It is also known as message-oriented middleware written in the Erlang programming language and built on the Open Telecom Platform framework for clustering and failover.
Rabbitmq is a scalable implementation of an AMQP broker. AMQP is the most widely used open-source standard for distributing and transferring messages from a source to a destination.
The Rabbitmq message broker system provides lot's of features some of them are listed below:
- Supports multiple protocols such as MQTT, STOMP and HTTP.
- Supports routing capabilities, you can implement rules to route messages between exchanges and queues.
- Supports multiple programming language with a variety of supported clients.
- Supports clustering, so you can clustered several rabbinmq server on local network.
- Supports high availability, so if a broker fails then communication will be redirected to different broker instance.
- Provides user friendly web interface to monitor and control every aspect of your message broker.
- Rabbitmq comes with lot's of plugins, you can easily extend it and also write your own.
- Rabbitmq provides tracing features that can be used to find out what's going on.
In this tutorial, we will learn how to install rabbitmq on Ubuntu 16.04 server.
Requirements
- A server running Ubuntu 16.04.
- A non-root user with sudo privileges configure on your server.
Update System
Before starting, you will need to update Ubuntu repository with the latest one.
You can do this by running the following commands:
sudo apt-get update -y
sudo apt-get upgrade -y
Installing Erlang
Before installing rabbitmq, you will need to install erlang as a prerequisite of rabbitmq. You can install them by running the following commands:
wget http://packages.erlang-solutions.com/ubuntu/erlang_solutions.asc
sudo apt-key add erlang_solutions.asc
sudo apt-get update -y
sudo apt-get install erlang -y
sudo apt-get install erlang-nox -y
Once you have Erlang, you can continue with installing RabbitMQ:
Installing RabbitMQ
First, you will need to add rabbitmq repository to apt. You can easily add it with the following command:
sudo echo 'deb http://www.rabbitmq.com/debian/ testing main' >> /etc/apt/sources.list
Once the repository is added, you will need to add the RabbitMQ public key to our trusted key list to avoid any warnings about unsigned packages:
wget https://www.rabbitmq.com/rabbitmq-signing-key-public.asc
sudo apt-key add rabbitmq-signing-key-public.asc
Next update the apt repository with the following command:
sudo apt-get update
Once the repository is up to date, then install rabbitmq server by running the following command:
sudo apt-get install rabbitmq-server
Once installation is complete, start the rabbitmq server and enable it to start on boot by running the following command:
sudo systemctl start rabbitmq-server
sudo systemctl enable rabbitmq-server
You can check the status of rabbitmq server with the following command:
Rabbitmq Install Windows
sudo systemctl status rabbitmq-server
RabbitMQ comes with default built-in settings which will quite likely be sufficient for running your RabbitMQ server effectively. If it runs fine, then you possibly don't need any configuration at all.
There are three way to customize RabbitMQ server.
- environment variables
You can define ports, file location and names using environment variable file.
- configuration file
You can defines server component settings for permissions, limits and clusters using configuration file.
- runtime parameters and policies You can defines cluster-wide settings which can change at run time .
You can find location of configuration file by inspecting RabbitMQ log file.
If you want to manage the maximum amount of connections upon launch, then you will need to modify rabbitmq-server
file located at /etc/default/ directory.
sudo nano /etc/default/rabbitmq-server
Find the line that containing word ulimit
and uncomment it:
Save and close the file, then you can proceed to next step.
Allow RabbitMQ Through Firewall
By default RabbitMQ web management console runs on port 15672
. So you will need to allow this port through UFW firewall. By default UFW firewall is disabled in Ubuntu 16.04, so you will need to enable it first.You can enable UFW filrewall with the following command:
sudo ufw enable
Once UFW is enabled, allow port 15672
using the following command:
sudo ufw allow 15672
Once you are done, you can proceed to next step.
Accessing RabbitMQ Web Management Console
Once everything is setup properly, it's time to access Rabbitmq web management console.Before starting, you will need to install rabbitmq web management plugin first. You can easily manage and monitor your RabbitMQ server in a variety of ways using this plugin.Using this console, you can manage queues, bindings and users, monitor queues, message rates, connections and also monitor Erlang processes, memory usage etc.
To install this plugin simply run the following command:
sudo rabbitmq-plugins enable rabbitmq_management
Rabbitmq Install Mac
The above command will enable the following plugins:
- mochiweb
- webmachine
- rabbitmq_web_dispatch
- amqp_client
- rabbitmq_management_agent
- rabbitmq_management
Once the plugin is enabled, you will need to restart rebbitmq service for the changes to come into effect.
Next, you will also need to create new admin user.
You can create a new admin user with the following commands:
sudo rabbitmqctl add_user radmin radmin
sudo rabbitmqctl set_user_tags radmin administrator
Before starting, you will need to update Ubuntu repository with the latest one.
You can do this by running the following commands:
sudo apt-get update -y
sudo apt-get upgrade -y

Sentora, an open source web hosting control panel alternative to popular Cpanel/WHM built specifically to work on a variety of Linux distributions such as Ubuntu, CentOS and more…
Cloud or VPS (virtual private hosting) servers are more popular nowadays because of the ability they provide a user to fully & easily manage the installation and hosting various kind of software or projects at a convenient price. However, the thing to be noted that these VPS or cloud servers, for example, Google cloud, AWS, DigitalOcean etc. only provides a bare server with options to install different Linux distributions with root permissions. Now it's upon you what you want to do further on that.
Apart from developing some applications, if you are not a developer and want to host your website or blog on Cloud hosting like Droplet of DigitalOcean then definitely you miss one thing i.e popular Cpanel. Albeit you can install the Cpanel/WHM on the DigitalOcean too but for that, you have to give license fee to Cpanel creators which is $20/month. However, Cpanel has its own benefits because of commercial support and regular security updates. But you can also choose some opensource CPanel alternative like Sentora. Although the Sentora is an opensource control panel, the premium support is available too. The benefit of Sentora is you don't have to pay for the software or updates.
So, let's see step by step guide to know how to install Sentora on Ubuntu or CentOS over the DigitalOcean Droplet cloud hosting.
Sentora requirements:
RightNow, the Sentora supports the CentOS 6, CentOS 7, Ubuntu 12.04 and Ubuntu 14.04. These are the officially approved Linux operating system where Sentora can work smoothly. Other Linux derivation can also be used base on the above given Linux distros but Snetora developer team will not be going to provide any kind of support to unsupported OS.
Also, we tried to install the Sentora on Ubuntu 16.04 and 18 but we got an error: Sorry, this os is not supported by sentora.
The process mentioned here is the same for installing the Sentora on CentOS 6, CentOS 7, Ubuntu 12.04 and Ubuntu 14.04; including the commands… Rammstein megamix.
One more thing that needs to be noted before installing the Sentora; make sure none these already been installed on your server.
- Any other Web or server management software should be installed prior to Sentora.
- None of the web services such as Nginx, MySQL, Apache, PHP, FTP Server, Mail Server, etc. should be on the server before installing Sentora.
- Ports those needed by the Santora to perform different operations
- 20 & 21 : FTP
- 25 (TCP) : SMTP
- 53 (TCP & UDP) : DNS
- 80 (TCP & UDP) : HTTP
- 110: POP3
- 143: IMAP
- If you want to use SSL then 443 for HTTPS and 3306 for MySQL
- 22 for SSH
Rabbitmq Install Management Plugin
Steps to Install Sentora on Ubuntu and Centos
Access Droplet Ubuntu or Centos server
Go to the DigitalOcean Droplet Ubuntu or Centos server. The steps given below are also applicable for the local installation in order to test the Sentora before going public.
Command to run:
- For both CentOS and Ubuntu, the following commands are work to install the Sentora Web Control Panel.
- First of all login to your server as root user:
- Make sure that you are on your home directory, in case not the type the below command:
- Run the command to download the Sentora installer
- If you get a certificate error from GitHub; try one of the two lines below:
- Make the installer executable:
- Run the installer:
- After the Sentora downloaded and installed, you will get an installation configuration screen to further configure for the web interface.
- First, it asks you to configure the Geographic area to select the time zone.
- Finally, select the time zone for your Sentora Control Panel.
- If you already have assigned the domain to the DigitalOcean then you can create a subdomain and assigned to Sentora web control panel right from this step. Otherwise just mentioned panel.yourdomian.com or whatever you want and later assigned into your DNS. For example, you can see that in the below image I got the warning that panel.how2shout.com is not defined in the DNS panel but nothing about to worry that can be set later. For now onwards just type the ‘y‘ and press the Enter button to move the installation further.
- The installer now setup Apache, PHP, MySQL and other web services those you need in a Web control panel. Once everything is set up, it will show the Sentora admin account password including MySQL username and password details. In case you want to access the password details later then you will get it from /root/passwords.txt file.
- Now type ‘Y' and press enter to restart the server for completing the Sentora installation.
How to access the Sentora web control panel GUI interface?
To access the web interface of the Sentrora Control Panel, go to the browser and use the public IP you got on DigitalOcean for your server. Or just configure the subdomain value and propagate the DNS to access the Sentora using the fully qualified sub-domain web address. If you are testing it locally then use your server local IP address.
Enter your Sentora Admin login details to access the control panel.
Once you Login successfully you can use the Sentora open source control panel to manage the website, database and all.
