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 18.04, 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.
Set Hostname
You can start by configuring the hostname for your server.
Set server hostname on CentOS 6:
$ cat /etc/sysconfig/network
NETWORKING=yes
HOSTNAME=mq-01.example.comRestart 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 --staticAdd EPEL repository:
Add epel repository to your system using yum command as below:
sudo yum -y install epel-releaseAdd Erlang repository and install Erlang.
wget http://packages.erlang-solutions.com/erlang-solutions-1.0-1.noarch.rpm
sudo rpm -Uvh erlang-solutions-1.0-1.noarch.rpm
sudo yum install erlangAdd RabbitMQ Repository:
For CentOS 7:
cat << EOF | sudo tee /etc/yum.repos.d/rabbitmq.repo
[bintray-rabbitmq-server]
name=bintray-rabbitmq-rpm
baseurl=https://dl.bintray.com/rabbitmq/rpm/rabbitmq-server/v3.8.x/el/7/
gpgcheck=0
repo_gpgcheck=0
enabled=1
EOFFor CentOS 6:
cat << EOF | sudo tee /etc/yum.repos.d/rabbitmq.repo
[bintray-rabbitmq-server]
name=bintray-rabbitmq-rpm
baseurl=https://dl.bintray.com/rabbitmq/rpm/rabbitmq-server/v3.8.x/el/6/
gpgcheck=0
repo_gpgcheck=0
enabled=1
EOFInstall rabbitmq-server package.
sudo yum -y install rabbitmq-serverStart and enable rabbitmq-server to start on boot.
CentOS 7:
sudo systemctl enable --now rabbitmq-serverCentOS 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 userEnable 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:
Login with username and the password created earlier:
