```
-## Example
+## Required Parameters
-1. Add two brokers
+**1. `<broker_name>`**
- ```sql
- ALTER SYSTEM ADD BROKER "host1:port", "host2:port";
- ```
-2. When fe enable
fqdn([fqdn](../../../admin-manual/cluster-management/fqdn.md)),add one Broker
+The name given to the added broker process. It is recommended to keep the
broker_name consistent within the same cluster.
- ```sql
- ALTER SYSTEM ADD BROKER "broker_fqdn1:port";
- ```
+**2. `<host>`**
+
+The IP of the node where the broker process needs to be added. If FQDN is
enabled, use the FQDN of the node.

default value of this port is 8000.
- ALTER, SYSTEM, ADD, FOLLOWER, ALTER SYSTEM
