shell腳本啓動kafka集羣

前提：kafka集羣之間已配置ssh免密登錄，kafka集羣配置路徑一致

要實現kafka羣起腳本
思路：通過ssh登錄後，循環啓動每臺機器的kafka和zookeeper

kafka和zookeeper單機啓動腳本：remote_server.sh 

#!/bin/bash
#zookeeper 進程號
ZK_PID=`ps -ef|grep zookeeper|grep -v grep|awk '{print $2}'`
#kafka 進程號
KAFKA_PID=`ps -ef|grep kafka|grep -v grep|awk '{print $2}'`
#機器的hostname
NODE_NAME=`hostname`
#選址“啓動服務”
case $1 in "start"){
#如果zookeeper進程存在
if [ -n "$ZK_PID" ];then
  echo "zkServer is already started"
else
  echo "starting zkServer.....";
  sh /apphome/zookeeper/zookeeper-3.4.14/bin/zkServer.sh "start";
  if [ $? -eq 0 ]; then
    echo "zkServer of $NODE_NAME started Success!"
  else
    echo "zkServer of $NODE_NAME started failure!"
  fi
fi
#如果kafka進程存在
if [ -n "$KAFKA_PID" ];then
  echo "KAFKA Server is already started"
else
  echo "starting KAFKA Server.....";
#啓動kafka
  echo "/apphome/kafka_2.11-0.11.0.0/bin/kafka-server-start.sh -daemon /apphome/kafka_2.11-0.11.0.0/config/server.properties" |sh
  if [ $? -eq 0 ]; then
    echo "KAFKA Server of $NODE_NAME started Success!"
  else
    echo "KAFKA Server of $NODE_NAME started failure!"
  fi
fi

};;
#如果選址“停止服務”
"stop"){
if [ -z "$KAFKA_PID" ];then
  echo "KAFKA Server is already stopped"
else
  echo "stopping KAFKA Server.....";
  sh /apphome/kafka_2.11-0.11.0.0/bin/kafka-server-stop.sh
  if [ $? -eq 0 ]; then
    echo "KAFKA Server of $NODE_NAME stopped Success!"
  else
    echo "KAFKA Server of $NODE_NAME stopped failure!"
  fi
fi

if [ -z "$ZK_PID" ];then
  echo "zkServer is already stopped"
else
  echo "stopping zkServer.....";
  sh /apphome/zookeeper/zookeeper-3.4.14/bin/zkServer.sh "stop";
  if [ $? -eq 0 ]; then
    echo "zkServer of $NODE_NAME stopped Success!"
  else
    echo "zkServer of $NODE_NAME stopped failure!"
  fi
fi

};;
esac

kafka集羣啓動入口：start-server-check.sh，在此腳本中連接ssh調用remote_server.sh 

#!/bin/bash
for ip in rabbit-node1 rabbit-node2 rabbit-node3
  do
   ssh $ip 'bash -s' <remote_server.sh "$1" 
  done

腳本執行：sh start-server-check.sh start  和  sh start-server-check.sh start
