Zookeeper、Kafka集群一键启动、关闭，脚本编写

Zookeeper集群一键启动

在 /usr/local/bin目录下创建脚本 zk

#!/bin/sh

case $1 in
"start"){
    
    

	for i in centos3 centos4 centos5
	do
		echo "********$i --> zkServer.sh start **********"
		ssh $i 'source /etc/profile; /opt/module/zookeeper/bin/zkServer.sh start;exit'
	done
};;

"stop"){
    
    

    for i in centos3 centos4 centos5
    do
        echo "********$i --> zkServer.sh stop **********"
        ssh $i 'source /etc/profile;  /opt/module/zookeeper/bin/zkServer.sh stop;exit'
    done
};;

"status"){
    
    

    for i in centos3 centos4 centos5
    do
        echo "********$i --> zkServer.sh status **********"
        ssh $i 'source /etc/profile; /opt/module/zookeeper/bin/zkServer.sh status;exit'
    done
};;
"restart"){
    
    

    for i in centos3 centos4 centos5
    do
        echo "********$i --> zkServer.sh restart **********"
        ssh $i 'source /etc/profile; /opt/module/zookeeper/bin/zkServer.sh restart;exit'
    done
};;
esac

可在任何位置执行该脚本
启动、查看状态、关闭zookeeper集群：
zk start

jps脚本查看执行进程

zk status

zk stop

kafka集群启动关闭脚本

/usr/local/bin下编写脚本 kk

#!/bin/sh

case $1 in
"start"){
    
    

        for i in centos3 centos4 centos5
        do
                echo "******** $i --> kafka-server-start.sh **********"
                ssh $i 'source /etc/profile;sh /opt/module/kafka/bin/kafka-server-start.sh -daemon /opt/module/kafka/config/server.properties'
        done

};;

"stop"){
    
    

        for i in centos3 centos4 centos5
        do
                echo "******** $i --> kafka-server-stop.sh **********"
                ssh $i 'source /etc/profile; /opt/module/kafka/bin/kafka-server-stop.sh /opt/module/kafka/config/server.properties;exit'
        done

};;
esac

启动kafka集群

查看启动进程

关闭kafka

xjps集群查看java进程脚本

#!/bin/sh

for i in centos3 centos4 centos5
do

   echo "============  $i -> jps============"
   ssh $i '/opt/module/jdk1.8.0_271/bin/jps'
done

/opt/module/jdk1.8.0_271为jdk安装目录
直接使用 xjps执行脚本。

本文脚本在集群中正常执行的前提

1. 修改集群中每个主机的/etc/hosts文件
   

2. 须生成rsa密钥，配置给从机(关键)
   可以参考xsync同步脚本的使用。

3. sync脚本

#!/bin/sh

# 获取输入参数个数，如果没有参数，直接退出
pcount=$#
if((pcount!=4)); then
    echo Usage: $0 filename servername startno endno
    exit;
fi


# 获取文件名称
p1=$1
fname=`basename $p1`
echo fname=$fname

# 获取上级目录到绝对路径
pdir=`cd -P $(dirname $p1); pwd`
echo pdir=$pdir
# 获取当前用户名称
user=`whoami`
# 获取hostname及起止号
slave=$2
startline=$3
endline=$4

# 循环
for((host=$startline; host<=$endline; host++)); do
    echo $pdir/$fname $user@$slave$host:$pdir
    echo ==================$slave$host==================
    rsync -rvl $pdir/$fname $user@$slave$host:$pdir
done

调用形式：xsync 文件或目录 centos 4 5

脚本文件存放目录：/usr/local/bin
