集群內快速同步配置

在多數集群中，節點的配置必須保持一致，一旦管理節點修改了配置，就需要把配置同步到其他節點，通常情況下是下面這樣的，它的缺點是每次都需要寫全路徑。

scp -r /path/conf node1:/path/conf

scp -r /path/conf node2:/path/conf
scp -r /path/conf node3:/path/conf

#!/bin/bash

[ $# -lt 1 ] && 
# nodes must can login without password
nodes=
(node1 node2 node3)
echo -n "action executing on hosts: $, [yes/no] "
read input
["$input"
=="yes"]||
exit 1
for host in
