利用Hadoop自带脚本编写一个一次启动集群的所有进程的脚本

准备工作，集群机器之间相互ssh免密登录

集群脚本注意脚本的权限和文件格式（若不会可参考本人以前的脚本问题的博客）

开启集群 start-jiqun

#!/usr/bin/env bash
echo "开启hdfs"
ssh hadoop01 "/home/hadoop/install/hadoop-2.5.0-cdh5.3.6/sbin/start-dfs.sh"
echo "开启历史服务器"
ssh hadoop01 "/home/hadoop/install/hadoop-2.5.0-cdh5.3.6/sbin/mr-jobhistory-daemon.sh start historyserver"
echo "开启yarn"
#resourcemanager在节点hadoop02上，后面为命令全路径
ssh hadoop02 "/home/hadoop/install/hadoop-2.5.0-cdh5.3.6/sbin/start-yarn.sh"

关闭集群 stop-jiqun

#!/usr/bin/env bash
echo "关闭hdfs"
ssh hadoop01 "/home/hadoop/install/hadoop-2.5.0-cdh5.3.6/sbin/stop-dfs.sh"
echo "关闭历史服务器"
ssh hadoop01 "/home/hadoop/install/hadoop-2.5.0-cdh5.3.6/sbin/mr-jobhistory-daemon.sh stop historyserver"
echo "关闭yarn"
ssh hadoop02 "/home/hadoop/install/hadoop-2.5.0-cdh5.3.6/sbin/stop-yarn.sh"

还有一些zookeeper，hive，Redis等后面再补上
