启动fe

sh bin/start_fe.sh --daemon
#连接fe
mysql -h IP -P 9030 -uroot -p

+be节点

#添加 be节点
ALTER SYSTEM ADD BACKEND "host:port";
#启动be
sh bin/start_be.sh --daemon
#查看be节点
SHOW PROC '/backends';
#删除be节点
ALTER SYSTEM dropp BACKEND "host:port";
#DECOMMISSION
ALTER SYSTEM DECOMMISSION BACKEND "be_host:be_heartbeat_service_port";

+broker节点

#启动broker
sh bin/start_broker.sh --daemon
#添加 Broker
ALTER SYSTEM ADD BROKER broker_name "host1:port1","host2:port2",...;
#查看 Broker 状态
SHOW PROC "/brokers";

扩容缩容

+fe Follower节点

# 添加Follower
ALTER SYSTEM ADD FOLLOWER "host:port";
# 启动 Follower
bin/start_fe.sh --helper host:port --daemon
# 查看 Follower 状态
SHOW PROC '/frontends';

+fe Observer节点

# 添加OBSERVER
ALTER SYSTEM ADD OBSERVER "host:port";
# 启动OBSERVER
bin/start_fe.sh --helper host:port --daemon
# 查看OBSERVER 状态
SHOW PROC '/frontends';

--helper 参数仅在 follower 和 observer 第一次启动时才需要。
