This guide will cover the steps required to Install RabbitMQ on CentOS 7 / CentOS 6 server. My Lab is based on my previous guide Using Vagrant with Libvirt on Linux. RabbitMQ is a message broker software that implements AMQP (Advanced Message Queuing Protocol).
For Ubuntu, check: How to install Latest RabbitMQ Server on Ubuntu
Installation Requirements:
- EPEL repository
- Erlang repository
- RabbitMQ repository
I prefer using repositories to install the Rabbitmq server and Erlang as opposed to using rpm packages which tends to bring package dependency issues and having to manually update packages.
Step 1: Set System Hostname
You can start by configuring the hostname for your server.
Set server hostname on CentOS 6:
$ sudo vi /etc/sysconfig/network
NETWORKING=yes
HOSTNAME=mq-01.example.com
Restart network service once you make the changes.
sudo /etc/init.d/network restartThen confirm current hostname setting:
$ hostname
mq-01.example.comTo temporarily set the hostname for the current shell session, use:
sudo hostname mq-01.example.comSet server hostname on CentOS 7:
For CentOS 7 server, you can easily set server hostname using a hostnamectl command.
sudo hostnamectl set-hostname mq-01.example.com --static
Step 2: Add EPEL repository
Add epel repository to your system using yum command as below:
sudo yum -y install epel-release wgetYou can check the repository has been added and working using the following command:
sudo yum repolistStep 3: Install Erlang
Add Erlang official YUM repository:
wget https://packages.erlang-solutions.com/erlang-solutions-2.0-1.noarch.rpm
sudo rpm -Uvh erlang-solutions-2.0-1.noarch.rpmThen install Erlang RPM package:
sudo yum install erlangAccept installation prompt and import GPG key:

qStep 4: Install RabbitMQ Server
Add RabbitMQ Repository:
Run the commands below to add RabbitMQ YUM repository to yourCentOS 7 / CentOS 6:
cat << EOF | sudo tee /etc/yum.repos.d/rabbitmq.repo
[rabbitmq_rabbitmq-server]
name=rabbitmq_rabbitmq-server
baseurl=https://packagecloud.io/rabbitmq/rabbitmq-server/el/\$releasever/\$basearch

gpgcheck=0
enabled=1
gpgkey=https://packagecloud.io/rabbitmq/rabbitmq-server/gpgkey
sslverify=1
sslcacert=/etc/pki/tls/certs/ca-bundle.crt
metadata_expire=300
EOFUpdate repositories cache
sudo yum clean all
sudo yum makecacheList available repositories as configured in the system:
$ sudo yum repolist

Use the commands below to start the service on CentOS 6:
sudo chkconfig rabbitmq-server on
sudo chkconfig --list | grep rabbitmq
sudo service rabbitmq-server startTo use RabbitMQ, add user first. By default, only guest user exists and he can connect from localhost.
$ rabbitmqctl add_user admin NUaiMe0k
Adding user "admin" ...
$ rabbitmqctl set_user_tags admin administrator
$ rabbitmqctl list_users
Listing users ...
admin [administrator]
guest [administrator]Other rabbitmqctl administration commands are:
Delete User:
rabbitmqctl delete_user userChange User Password:
rabbitmqctl change_password user strongpasswordAdd virtualhost:
rabbitmqctl add_vhost /my_vhostList virtualhosts:
rabbitmqctl list_vhostsDelete virtualhost:
rabbitmqctl delete_vhost /my_vhostGrant user permissions for vhost:
rabbitmqctl set_permissions -p /my_vhost user ".*" ".*" ".*"List vhost permissions:
rabbitmqctl list_permissions -p /my_vhostTo list user permissions:
rabbitmqctl list_user_permissions userDelete user permissions:
rabbitmqctl clear_permissions -p /my_vhost userStep 5: Enable RabbitMQ UI
You can enable the Management Plugin to use a web-based interface to administer RabbitMQ.
### For CentOS 7 ###
sudo rabbitmq-plugins enable rabbitmq_management
sudo systemctl restart rabbitmq-server
### For CentOS 6 ###
sudo service rabbitmq-server restartConfigure Firewall
Open ports on the firewall:
sudo firewall-cmd --add-port={4369/tcp,25672}/tcp --permanentWith Iptables:
sudo iptables -A INPUT -p tcp -m tcp --dport 4369 -j ACCEPT
sudo iptables -A INPUT -p tcp -m tcp --dport 25672 -j ACCEPTAccess RabbitMQ Admin web console
Access to the “http://server:15672/” from a client: You should get a login window:
