Creating a RabbitMQ Virtual Host

Each virtual host serves as an independent RabbitMQ server. Virtual hosts provide logical separation of exchanges, queues, and bindings. Different applications run on different virtual hosts without interfering with each other. An instance can have multiple virtual hosts, and a virtual host can have multiple exchanges and queues. To connect a producer or consumer to a RabbitMQ instance, you must specify a virtual host. For details, see Virtual Hosts on the official RabbitMQ website.

Methods of creating a virtual host:

After an instance is created, a virtual host named / is automatically created.

Creating a RabbitMQ Host (Console)

  1. Log in to the console.
  2. In the upper left corner, click and select a region.

    Select the region where your RabbitMQ instance is.

  3. Click and choose Application > Distributed Message Service for RabbitMQ to open the console of DMS for RabbitMQ.
  4. Click an instance name to go to the instance details page.
  5. In the navigation pane, choose Virtual Hosts.
  6. Click Create Virtual Host.

    Once a virtual host is created, its name is fixed and it is displayed in the virtual host list.
