Hbase配置文件从Master到Slave同步

对于其中使用的rsync ,参见:rsync 的基本使用

#!/bin/bash
# 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...";
# –v 表示复杂的输出信息 ; -a 表示权限保存模式,相当于 -rlptgoD 参数.很快速的保存几乎所有的权限设定,除了硬式连接 ;-z 表示压缩

# 指定排除一个不需要传输的文件匹配模式  

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."

同样的功能，下面的简单些

#!/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..."; 

#  ––delete    删除那些接收端还有而发送端已经不存在的文件 
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."
