Shell：Zookeeper简单的群起脚本

1、在自己的用户下创建脚本文件（此目录下的脚本Mark用户可以在任何情景下使用）

[code][Mark@hadoop102 bin]$ cd /home/Mark/bin
[Mark@hadoop102 bin]$ mkdir zkS.sh

2、进入文件编写脚本内容

[code][Mark@hadoop12 bin]$ vim zkS.sh

[code]#!/bin/bash
if (($#==0))
then
exit 1;
fi
for i in hadoop12 hadoop13 hadoop14
do
echo "=====================  Starting zk in $i  ======================="
ssh $i "zkServer.sh $1" 2> /dev/null
done

3、执行脚本

[code][Mark@hadoop12 ~]$ zkS.sh start

 执行结果：

[code]=====================  Starting zk in hadoop12  =======================
Starting zookeeper ... STARTED
=====================  Starting zk in hadoop13  =======================
Starting zookeeper ... STARTED
=====================  Starting zk in hadoop14  =======================
Starting zookeeper ... STARTED
