zookeeper集羣一鍵啓動shell腳本

1.我腳本放在/root/bin下面,命名zkmanager.sh

2.root目錄下面沒有bin目錄就創建 mkdir /root/bin -p

3.創建zkmanager.sh腳本,vim zkmanager.sh(沒有vim可以安裝,也可以用vi,vim安裝yum -y install vim*)

4.編寫shell腳本

#!/bin/bash
echo $1"ing zkServer ..."

for i in 2 3 4 5
  do
    echo "centos10"$i" is "$1"ing..."
    ssh centos10$i "source /etc/profile;/home/hadoop/apps/zookeeper-3.4.10/bin/zkServer.sh $1"
  done
  
sleep 2

for i in 2 3 4 5
  do
    ssh centos10$i "source /etc/profile;/home/hadoop/apps/zookeeper-3.4.10/bin/zkServer.sh status"
  done

5.爲了方便導出都可以啓動,可以把/root/bin加入環境變量

6.source /etc/profile

7.啓動zkmanager.sh start

8.停止zkmanager.sh stop
