Zookeeper-批量启动和停止zookeeper节点脚本

背景

由于zookeeper的服务启动和停止，需要一台一台地去启动和停止。当部署的zookeeper节点多时非常麻烦，所以编写下面的脚本，用于提升启动和停止的效率。

执行如下脚本需要确保：脚本存放的服务器与所有的zookeeper节点直接可以免密登录（服务器之间建立互信）。

1、编辑脚本

vi manage-zookeeper.sh

#!/bin/bash

zookeeper_home=/usr/local/zookeeper
zookeeper_array=(hadoop01 hadoop02 hadoop03)

## 启动和停止Zookeeper
function zookeeper_operate(){
    zookeeper_operate=$@
    if [[ ${zookeeper_operate} == "status" ]]
    then
        echo "~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~"
        echo "About to check  zookeeper  status ...."
        sleep  5
    fi
    echo "****************************************Zookeeper ${zookeeper_operate}*******************************************"
    for zookeeper_node in ${zookeeper_array[@]}
    do
        echo "======================${zookeeper_node} ${zookeeper_operate}========================"
        ssh ${zookeeper_node} "source /etc/profile;${zookeeper_home}/bin/zkServer.sh  ${zookeeper_operate}"
        if [[ ${zookeeper_node} == "stop" ]]
        then
            ssh  ${zookeeper_node}  "rm -rf ${zookeeper}/logs/* "
        fi
    done

}


echo  "=======Start Zookeeper cluster,please intput : start or 1 ======"
echo  "=======Stop  Zookeeper cluster,please intput : stop  or 0 ======"
read -p "please input : "  inputStr
case ${inputStr} in 
    start|START|1)
        ## 启动zookeeper 
        zookeeper_operate  start 
        ## 检查所有节点的状态
        zookeeper_operate  status 
    ;;
    stop|STOP|0)
        zookeeper_operate   stop
        zookeeper_operate   status
    ;;
    *)
        echo "Input wrong,please check!"
        break
