Kafka还能这样玩！同时启/停Kafka所有节点脚本

Kafka并没有提供同时启动集群中所有节点的执行脚本，在生产中一个Kafka集群往往会有多个节点，若逐个节点启动稍微有些麻烦，在这里自定义一个脚本用来启动或者停止集群中所有节点。

启动：

#!/bin/bash

brokers="hadoop3 hadoop4 hadoop5"
KAFKA_HOME="/opt/kafka/kafka_2.11-1.0.0"

echo "INFO:Begin to start kafka cluster..."

for broker in $brokers
do
		echo "INFO:Start kafka on ${broker} ..."
		ssh $broker -C "source /etc/profile; sh ${KAFKA_HOME}/bin/kafka-server-start.sh -daemon ${KAFKA_HOME}/config/server.properties" 
		if [ $? -eq 0 ]; then
				echo "INFO:[${broker}] Start successfully "
		fi
done

echo "INFO:Kafka cluster starts successfully!"

停止：

#!/bin/bash

brokers="hadoop3 hadoop4 hadoop5"
KAFKA_HOME="/opt/kafka/kafka_2.11-1.0.0"

echo "INFO:Begin to stop kafka cluster..."

for broker in $brokers
do
		echo "INFO:Stop kafka on ${broker} ..."
		ssh $broker -C "source /etc/profile; sh ${KAFKA_HOME}/bin/kafka-server-stop.sh" 
		if [ $? -eq 0 ]; then
				echo "INFO:[${broker}] Stop successfully "
		fi
done

echo "INFO:Kafka cluster stop successfully!"
