Kafka集群启停脚本参考

对kafka-server-start.sh脚本和kafka-server-stop.sh脚本进行二次封装

#! /bin/bash

# Kafka代理节点地址, 如果节点较多可以用一个文件来存储
hosts=(dn1 dn2 dn3)

# 打印启动分布式脚本信息
mill=`date "+%N"`
tdate=`date "+%Y-%m-%d %H:%M:%S,${mill:0:3}"`

echo [$tdate] INFO [Kafka Cluster] begins to execute the $1 operation.

# 执行分布式开启命令

            sleep 1
