编写zookeeper远程执行脚本过程中出现，zookeeper进程不能正常启动的问题：

进入配置文件conf目录下，查看zookeeper.out文件，内容如下所示：

问题：通过分析异常代码可以看出是java异常的问题，没有找到java的路径
解决方案：在配置文件中加入java的路径
打开文件 vi /etc/profile

# java_home
# java
export JAVA_HOME=/home/serverai/bigdata/jdk1.8.0_221
export PATH=:{JAVA_HOME}/bin:$PATH

更新配置source /etc/profile

执行的脚本代码如下：
zookeeper集群启动脚本,zk-all-start.sh

#!/usr/bin/env bash

for host in hadoopmaster hadoopslave01 hadoopslave02
do
# 输出当前服务器的zookeeper启动情况
echo "{$host} start zkServer..."
# 启动zookeeper根据自己安装路径修改
ssh $host "source /etc/profile;/root/bigdata/zookeeper-3.4.9/bin/zkServer.sh start"
done

sleep 2

for host in hadoopmaster hadoopslave01 hadoopslave02
do
echo "{$host} zkServer status..."
# 显示状态
ssh $host "source /etc/profile;/root/bigdata/zookeeper-3.4.9/bin/zkServer.sh status"
done

zookeeper集群停止脚本,zk-all-stop.sh

#!/usr/bin/env bash

for host in hadoopmaster hadoopslave01 hadoopslave02
do
# 输出当前服务器的zookeeper启动情况
echo "{$host} start zkServer..."
# 启动zookeeper根据自己安装路径修改
ssh $host "source /etc/profile;/root/bigdata/zookeeper-3.4.9/bin/zkServer.sh stop"
done

sleep 2

for host in hadoopmaster hadoopslave01 hadoopslave02
do
echo "{$host} zkServer status..."
# 显示状态
ssh $host "source /etc/profile;/root/bigdata/zookeeper-3.4.9/bin/zkServer.sh status"
done
