Step-by-Step Guide to Installing and Configuring RabbitMQ on CentOS 7

1. Environment Setup: Use CentOS 7.x (free) as the operating system.

2. Install required plugin: Install yum install socat -y because RabbitMQ depends on the socat utility.

3. Install Erlang: Download the Erlang package from https://packagecloud.io/rabbitmq/erlang/packages/el/7/erlang-21.3.8.16-1.el7.x86_64.rpm and install it with the following commands:

curl -s https://packagecloud.io/install/repositories/rabbitmq/erlang/script.rpm.sh | sudo bash
sudo yum install erlang-21.3.8.16-1.el7.x86_64

Verify the installation with erl -v .

4. Install RabbitMQ Server: Download the source package from https://github.com/rabbitmq/rabbitmq-server/releases , extract it, configure, compile and install:

wget https://github.com/rabbitmq/rabbitmq-server/archive/refs/tags/v3.10.7.tar.gz
tar -axvf v3.10.7.tar.gz
cd v3.10.7
./configure --prefix=/etc/erlang
make && make install

Start the service and check its status:

systemctl start rabbitmq-server
systemctl status rabbitmq-server

Enable the service to start on boot and manage its lifecycle:

systemctl enable rabbitmq-server
systemctl stop rabbitmq-server
systemctl restart rabbitmq-server

5. Enable Management Plugin: Activate the web management UI with rabbitmq-plugins enable rabbitmq_management and restart the server.

Access the UI at http:// your_ip :15672 using the default credentials guest / guest .

6. User Management: Create users, assign tags, set permissions, change passwords, and delete users using rabbitmqctl commands, for example:

rabbitmqctl add_user username password
rabbitmqctl set_user_tags username role
rabbitmqctl set_permissions -p "/" username ".*" ".*" ".*"
rabbitmqctl change_password username new_password
rabbitmqctl delete_user username
rabbitmqctl list_user

These steps complete the installation, configuration, and basic administration of RabbitMQ on a CentOS 7 system.
