【4】Kafka集群启动/关闭脚本

说明：本脚本基于SSH服务器免密登录，如集群未配置SSH，参照：《SSH安装配置》 。

一、启动脚本：start-kafka-cluster.sh

#!/bin/bash
brokers="server1 server2 server3"
KAFKA_HOME="/usr/local/services/kafka/kafka_2.11-2.3.0"
KAFKA_NAME="kafka_2.11-2.3.0"

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

for broker in $brokers
do
  echo "INFO : Starting ${KAFKA_NAME} 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 !"

为脚本添加执行权限：

chmod a+x start-kafka-cluster.sh

二、停止脚本：stop-kafka-cluster.sh

#!/bin/bash
brokers="server1 server2 server3"
KAFKA_HOME="/usr/local/services/kafka/kafka_2.11-2.3.0"
KAFKA_NAME="kafka_2.11-2.3.0"

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

for broker in $brokers
do
  echo "INFO : Shut down ${KAFKA_NAME} on ${broker} ..."
  ssh ${broker} "source /etc/profile;bash ${KAFKA_HOME}/bin/kafka-server-stop.sh"
  if [[ $? -ne 0 ]]; then
      echo "INFO : Shut down ${KAFKA_NAME} on ${broker} is down"
  fi
done

echo "INFO : kafka cluster shut down completed!"

为脚本添加执行权限：

chmod a+x stop-kafka-cluster.sh
