+**Install rabbitmq-server**
+
+Reference: `lindevs.com/install-rabbitmq-on-ubuntu/ <https://lindevs.com/install-rabbitmq-on-ubuntu/>`_
+
+.. code-block:: bash
 
     sudo apt update && sudo apt upgrade && sudo apt install wget -y
-    echo "deb https://packages.erlang-solutions.com/ubuntu focal contrib" | sudo tee /etc/apt/sources.list.d/rabbitmq.list

+    # add the erlang repository
+    sudo add-apt-repository -y ppa:rabbitmq/rabbitmq-erlang
 
-    sudo apt update
-    sudo apt install erlang
+    # add the rabbitmq repository
+    wget -qO - https://packagecloud.io/install/repositories/rabbitmq/rabbitmq-server/script.deb.sh | sudo bash

+    sudo apt install -y rabbitmq-server
 
-    sudo apt update
-    sudo apt install rabbitmq-server
+    # check the status (it should already be running)
+    sudo systemctl status rabbitmq-server
 
-    sudo systemctl start rabbitmq-server.service
-    sudo systemctl enable rabbitmq-server.service
+    # check the service is enabled (it should already be enabled)
+    sudo systemctl is-enabled rabbitmq-server.service
 
-    systemctl is-enabled rabbitmq-server.service
+    # enable the web frontend and allow access through firewall
+    # view this interface at http://<your ip>:15672
     sudo rabbitmq-plugins enable rabbitmq_management
     sudo ufw allow proto tcp from any to any port 5672,15672
 
+**Create admin user**
+
+This is the user that GeoNode will use to communicate with rabbitmq-server.
+
+.. code-block::
+
     sudo rabbitmqctl delete_user guest
     sudo rabbitmqctl add_user admin <your_rabbitmq_admin_password_here>
-    sudo rabbitmqctl change_password admin <your_rabbitmq_admin_password_here>
     sudo rabbitmqctl set_user_tags admin administrator
     sudo rabbitmqctl add_vhost /localhost
     sudo rabbitmqctl set_permissions -p / admin ".*" ".*" ".*"
     sudo rabbitmqctl set_permissions -p /localhost admin ".*" ".*" ".*"
 
+**Managing RabbitMQ**
+
+You can manage the rabbitmq-server service like any other service::
+
+    sudo systemctl stop rabbitmq-server
+    sudo systemctl start rabbitmq-server
+    sudo systemctl restart rabbitmq-server
+
+You can manage the rabbitmq-server node with `rabbitmqctl <https://www.rabbitmq.com/rabbitmqctl.8.html>`_.
+For example, to fully reset the server, use these commands::
+
+    sudo rabbitmqctl stop_app
+    sudo rabbitmqctl reset
+    sudo rabbitmqctl start_app
+
+After reset, you'll need to recreate the ``admin`` user (see above).
