复制master节点上的版本内容到所有slaves节点上

注意：

1：版本目录做了软链接，如 ln -s hbase-0.94.6 hbase

2: 要根据实际情况，将/usr/local/修改为hbase所在的目录

#!/bin/bash
# copy a new release of HBase from the masternode to all slave nodes
# Rsyncs HBase files across all slaves. Must run on master.
# Assumes all files are located in /usr/local
if [ "$#" != "2" ]; then
        echo "usage: $(basename $0) <dir-name> <ln-name>"
        echo " example: $(basename $0) hbase-0.1 hbase"
        exit 1
fi

SRC_PATH="/usr/local/$1/conf/regionservers"

for srv in $(cat $SRC_PATH); do
        echo "Sending command to $srv...";
        rsync -vaz --exclude='logs/*' /usr/local/$1 $srv:/usr/local/
        ssh $srv "rm -fR /usr/local/$2 ; 
        ln -s /usr/local/$1 /usr/local/$2"
done
echo "done."

同步master节点上的配置文件到所有region servers

注意：

1：版本目录做了软链接，如 ln -s hbase-0.94.6 hbase

2: 要根据实际情况，将/usr/local/修改为hbase所在的目录

#!/bin/bash
# Rsync's HBase config files across all region servers. Must run on master.
for srv in $(cat /usr/local/hbase/conf/regionservers); do
	echo "Sending command to $srv...";
	rsync -vaz --delete --exclude='logs/*' /usr/local/hadoop/ $srv:/usr/local/hadoop/
	rsync -vaz --delete --exclude='logs/*' /usr/local/hbase/ $srv:/usr/local/hbase/
done
echo "done."

rsync命令简介

Rsync（remote synchronize）是一个远程数据同步工具，可通过LAN/WAN快速同步多台主机间的文件。Rsync使用所谓的“Rsync算法”来使本地和远程两个主机之间的文件达到同步，这个算法只传送两个文件的不同部分，而不是每次都整份传送，因此速度相当快。

工作模式

rsync [OPTION]... SRC DEST
rsync [OPTION]... SRC [USER@]HOST:DEST
rsync [OPTION]... [USER@]HOST:SRC DEST
rsync [OPTION]... [USER@]HOST::SRC DEST
rsync [OPTION]... SRC [USER@]HOST::DEST
rsync [OPTION]... rsync://[USER@]HOST[:PORT]/SRC [DEST]
